15 Best Antioxidant Supplements to Boost Cell Vitality

Your DNA sustains roughly 10,000 oxidative lesions per cell, per day. Meanwhile, blood levels of glutathione—your body's master antioxidant—steadily decline after age 40, widening the gap between damage and defense. This invisible war between free radicals and your cellular defenses determines how quickly you age, how resilient your immune system remains, and whether your skin, heart, and brain stay vibrant or deteriorate prematurely.

The 15 best antioxidant supplements in this guide can help close that gap. By neutralizing free radicals before they damage your DNA, proteins, and cell membranes, targeted antioxidants support everything from cardiovascular function and cognitive clarity to youthful skin and sustained energy. It's no coincidence that populations with the highest antioxidant intake—particularly those following traditional Mediterranean diets rich in olive polyphenols—consistently show lower rates of heart disease, cognitive decline, and premature aging.

Modern supplementation makes it possible to capture these benefits without overhauling your entire diet. Below, we've curated 15 top antioxidant supplements across various categories, with Olivea's EVOO & Hydroxytyrosol Supplement leading for its exceptional polyphenol potency and absorption.

How We Rate Antioxidant Supplements

Choosing an outstanding antioxidant supplement requires digging deeper than marketing claims. We evaluated products on four key criteria to ensure you get effective, safe, and bioavailable antioxidants:

1. Scientific Evidence Base – 35%

Does it actually work? This is the foundation of our evaluation. We prioritize supplements backed by peer-reviewed clinical research—not marketing hype or cherry-picked testimonials. The top products feature ingredients with documented antioxidant benefits at specific, therapeutic dosages. Take Olivea, which provides 20 mg of hydroxytyrosol, four times the European Food Safety Authority's recommended minimum, because that's the dose research validates. If credible science doesn't support the claims, we don't recommend it.

2. Potency of Active Antioxidants – 25%

Are you getting enough to make a difference? Underdosed supplements are a waste of your money. We sought products delivering meaningful amounts of antioxidants, whether specific polyphenols with proven potency or high-ORAC whole-food concentrates. The best supplements clearly disclose their antioxidant content and standardization levels—no proprietary blend hiding games. Higher potency means stronger free-radical protection and more noticeable results for your skin, energy, and cardiovascular and overall health.

3. Formulation Quality and Bioavailability – 20%

Can your body actually absorb it? Even powerful antioxidants are worthless if they pass through your system unused. We favor products employing advanced delivery technologies that enhance absorption. Superior formulation means antioxidants reach your cells where they can protect, repair, and rejuvenate.

4. Ingredient Integrity and Purity – 20%

Is it clean and trustworthy? We examined every supplement for quality and transparency. Top-rated products feature pristine formulas without unnecessary fillers, questionable additives, or hidden allergens. Supplements using organic, non-GMO, vegan, and allergen-free ingredients scored higher, as did those sourcing bioactive or wildcrafted ingredients over cheap synthetics. The best antioxidant supplements combine potent actives with clean ingredient profiles—delivering maximum benefits without compromise.

Let’s now dive deeper into detailed reviews of each supplement, understanding their unique strengths, limitations, and how they compare directly to the benchmark set by Olivea.

1. Olivea EVOO & Hydroxytyrosol Supplement – Best Overall Antioxidant Supplement for Skin, Aging, and Heart Health

Active Ingredients

Olivea’s signature formula delivers 20 mg of pure hydroxytyrosol per capsule, suspended in high-phenolic extra virgin olive oil for optimal absorption. Hydroxytyrosol is the star polyphenol from olives, and Olivea packs it in via a patented capsule-in-capsule design: an inner core of concentrated hydroxytyrosol nested inside a liquid EVOO capsule. This provides the full spectrum of olive’s antioxidants in a natural olive oil matrix.

The result is a medical-grade olive polyphenol supplement—essentially the benefits of 100 tablespoons of extra virgin olive oils, without the calories. Each capsule is non-GMO, organic, vegan, pesticide-free, and made from early-harvest Greek olives rich in polyphenols.

Key Antioxidant Benefits

• Heart and Vascular Health: Hydroxytyrosol helps prevent LDL cholesterol oxidation, protecting arteries from plaque formation. Olivea’s 20 mg dose exceeds the 5 mg/day EFSA recommendation for cardiovascular antioxidant benefits. This can support healthy blood pressure, improved cholesterol ratios, and reduced risk of heart attack or stroke.

• Longevity & Anti-Aging: Olive polyphenols have been linked to lower mortality—high olive oil intake correlates with 17% reduced risk of cancer and neurodegenerative death in studies. Hydroxytyrosol’s ORAC antioxidant score is among the highest known, scavenging free radicals system-wide to slow cellular aging.

• Brain Protection: As a unique polyphenol that crosses the blood-brain barrier, hydroxytyrosol can directly combat neuronal oxidative stress. This may support cognitive function and guard the brain as we age. In an Auburn University clinical trial demonstrated that extra virgin olive oil uniquely crosses the blood-brain barrier to reduce amyloid-β accumulation and protect neurons from oxidative damage—two critical factors in Alzheimer's prevention

• Anti-Inflammatory & Metabolic Support: Olivea EVOO and Hydroxytyrosol supplement may help lower systemic inflammation by neutralizing inflammatory free radicals. Users have noted benefits like reduced joint pain and healthier metabolism. Olive polyphenols can improve endothelial function and insulin sensitivity, contributing to overall vitality and energy.

Why Olivea EVOO & Hydroxytyrosol Supplement for Antioxidant Support

Hydroxytyrosol is one of the most powerful natural antioxidants ever measured—stronger than vitamin C, vitamin E, or resveratrol. It neutralizes free radicals before they damage your cells, oxidize your cholesterol, or break down collagen in your skin. Olivea delivers 20 mg per capsule, four times what European regulators recognize as effective for protecting blood lipids from oxidative stress.

Most antioxidants lose potency before reaching your bloodstream. Olivea solves this with a capsule-in-capsule design that suspends hydroxytyrosol in extra virgin olive oil, ensuring absorption rather than waste. One capsule delivers the health benefits of 100 tablespoons of extra virgin olive oil.

The result is antioxidant protection across your whole body—defending arteries, slowing oxidative aging in skin, and supporting healthy heart, brain, and cellular function. For a single supplement with the broadest antioxidant reach and strongest clinical backing, Olivea is the clear choice.

Pros & Cons of Olivea

Who Is Olivea EVOO & Hydroxytyrosol Supplement For?

Olivea is ideal for adults 30+ who are proactive about long-term health and longevity. Consider this supplement if you:

• Have a family history of heart disease, high cholesterol, or stroke, and want extra arterial protection

• Follow a longevity or Mediterranean-style lifestyle—Olivea delivers olive oil’s life-extending compounds without excess calories.

• Are focused on brain health and cognitive aging, especially if you don’t regularly consume olive oil (hydroxytyrosol helps support memory and neuronal health).

• Prefer natural, food-based supplements with rigorous science behind them. Olivea appeals to those seeking a potent yet holistic antioxidant source.

• Are health-conscious or biohackers aiming to reduce inflammation and oxidative stress as part of an anti-aging regimen.

• Want to“age-proof” your cardiovascular system and overall health in a convenient way.

Olivea vs Other Antioxidant Supplements

Most antioxidant supplements fall into two camps: broad-spectrum blends with dozens of ingredients at tiny doses, or single vitamins like C and E that cover the basics but little else. Olivea takes a different approach—one clinically validated compound at a dose that actually works.

Hydroxytyrosol outperforms popular antioxidants like vitamin C, vitamin E, and resveratrol in free-radical scavenging power. At 20 mg per capsule, Olivea provides four times what European regulators consider the minimum effective dose. Most competitors don't come close to this potency, and those that do often use dry powder formats with poor absorption.

This is where Olivea pulls ahead. Its capsule-in-capsule design delivers hydroxytyrosol suspended in extra virgin olive oil—so it actually reaches your bloodstream instead of passing through unused. Broad-spectrum blends and standard capsules can't match this bioavailability, which means you'd need to take far more of them to achieve the same antioxidant effect.

For anyone who wants real free-radical protection rather than a long ingredient list, Olivea offers the strongest combination of potency, absorption, and clinical evidence in a single daily capsule.

2. Olivie Anti-Age – Best Whole-Food Antioxidant

Active Ingredients

Olivie Anti-Age is an organic, whole-plant olive supplement harnessing the entire olive tree’s polyphenols. Each 500 mg vegetarian capsule contains powder from olive fruits, mature leaves, young buds, and olive oil—all USDA organic. Key active compounds include hydroxytyrosol, tyrosol, oleuropein and other olive antioxidants in their natural ratios. Olivie adds a bit of its own organic olive oil into the capsule as well, to improve absorption of these fat-soluble nutrients. Essentially, it’s 100% olive-derived nutrition—“food in a capsule” that captures the synergy of the whole olive tree.

Key Antioxidant Benefits

• Active Cellular Rejuvenation: The broad spectrum of olive polyphenols in Olivie stimulates mitochondrial biogenesis, helping your cells produce more energy and stay biologically “younger.” This can enhance vitality and slow cellular aging at the root level. Users often report improvements in skin radiance and energy levels, aligning with the product’s anti-aging focus.

• Powerful Free Radical Neutralization: Olivie Anti-Age boasts an ORAC antioxidant value over 250,000 μmol TE/100g, among the highest ever reported. In fact, it’s said to have 200× the antioxidant power of curcumin by ORAC. This intense free radical scavenging can protect DNA, lipids, and proteins from oxidative damage throughout the body.

• Whole-Food Synergy: Because it contains the olive’s full matrix (polyphenols plus fiber and micronutrients), it may provide more comprehensive benefits than isolated extracts. For example, oleuropein supports immune function and metabolism, while hydroxytyrosol handles oxidative stress – together they cover multiple health angles. This synergy can help with inflammation reduction and overall resilience.

• Heart and Metabolic Health: The combination of hydroxytyrosol and oleuropein in Olivie has EFSA-validated antioxidant effects on blood lipids. Regular use may improve cholesterol profiles and blood pressure moderation.

Why Olivie Anti-Age for Antioxidant Support

Olivie Anti-Age takes a holistic approach: instead of delivering one superstar ingredient, it leverages the entourage effect of the olive tree’s multiple antioxidants. This supplement is essentially a concentrated olive superfood. For those who believe nutrients work best in their natural context, Olivie is compelling. The product boasts its extreme potency, reporting that one capsule provides the polyphenols of 2 liters of regular olive oil. It’s also certified organic and free of any synthetic additives, appealing to clean-label enthusiasts.

Including Olivie into your diet can mean that you’re essentially getting the benefits of an olive-rich diet in a convenient capsule. It’s like a potent olive leaf tea, olive oil, and olive fruit extract all in one. This makes it a top pick for anti-aging enthusiasts who want a natural, food-based supplement that doesn’t compromise on strength.

Pros & Cons of Olivie Anti-Age

Who Is Olivie Anti-Age For?

This supplement appeals to individuals who favor a natural, minimally processed route to health. You might consider Olivie if you:

• Are a natural/organic lifestyle devotee, who wants antioxidants from whole foods rather than lab-isolated chemicals.

• Believe in “food as medicine” and you prefer consuming nutrients in their native matrix for synergy.

• Are sensitive to synthetic additives. Olivie contains no fillers, binders, or synthetic vitamins, reducing risk of reactions.

• Want gentle immune support. Olive leaf is known for its immune-modulating and antimicrobial properties.

Olivie vs Olivea

Both products come from the olive tree, but that's where the similarities end. Olivie Anti-Age takes a whole-food approach, combining olive leaves, fruit, and oil into a broad-spectrum blend. The upside is natural synergy; the downside is unpredictability. Olivie doesn't disclose how much hydroxytyrosol you're actually getting per capsule, and as a whole-food product, potency can shift from batch to batch.

Olivea goes the opposite direction: one compound, one standardized dose, proven absorption. Every capsule delivers exactly 20 mg of hydroxytyrosol—the amount clinical research supports for meaningful antioxidant protection. And because it's suspended in extra virgin olive oil rather than packed as dry powder, your body actually absorbs it.

For serious antioxidant support, Olivea is the clear winner. It offers the precise dosing, guaranteed potency, and superior bioavailability that Olivie simply can't match. Olivie may appeal to those who prefer whole-food labels, but when it comes to measurable results, Olivea delivers what actually matters.

3. ProHealth Hydroxytyrosol Extreme – Best Single-Ingredient Antioxidant Formula

Active Ingredients

ProHealth’s Hydroxytyrosol Extreme is a single-ingredient powerhouse. Each vegetarian capsule provides 100 mg of Olea25® olive leaf extract, standardized to 25 mg of pure hydroxytyrosol. It’s free of gluten, soy, dairy, and artificial fillers. Essentially, ProHealth Extreme is hydroxytyrosol in its purest capsule form, designed for maximum potency.

Key Antioxidant Benefits

• Cardiovascular Protection: With 25 mg hydroxytyrosol per pill, this formula packs more of this heart-healthy antioxidant than many clinical studies even used.

• Anti-Inflammatory & Immune Support: Hydroxytyrosol’s potent antioxidant action also translates to reduced inflammation markers. One 2023 human study found that hydroxytyrosol can lower inflammatory cytokines and even modulate immune response.

• Anti-Aging & Cellular Health: High-dose hydroxytyrosol can trigger cellular antioxidant defenses. This helps protect mitochondria and DNA from age-accelerating free radicals. Over time, one might experience improved skin health and more resilient cells. In fact, ProHealth’s cites an ORAC value of 68,576 μmol TE for their Olea25® extract. That suggests significant anti-aging potential.

Why ProHealth Hydroxytyrosol Extreme for Antioxidant Support

If you’re looking for pure, unadulterated potency, ProHealth’s Hydroxytyrosol Extreme is hard to beat. It was selected as the “Highest Potency” option in our research on best hydroxytyrosol supplements for delivering 25 mg in one capsule, which is at or above the dose shown effective in various studies. ProHealth uses the top-notch Olea25® extract, ensuring you’re getting a reliable and standardized polyphenol content every time.

Another big plus: the formula is extremely clean and allergen-free. It contains no unnecessary herbs or mixes—just the olive phenol. This makes it easy to combine with other supplements without worrying about interactions. It’s a “no fluff” supplement, so you pay for hydroxytyrosol and that’s what you get, at a strength that rivals any competitor.

Pros & Cons of ProHealth Hydroxytyrosol Extreme

Who Is ProHealth Hydroxytyrosol Extreme For?

This antioxidant supplement is tailored for the advanced health optimizer or specific-condition user. You’ll likely benefit from ProHealth Extreme if you:

• Demand high potency—you want the absolute highest intake of olive’s key antioxidant without dilution.

• Already take oils or a fatty diet, since there’s no oil in the capsule, it’s perfect if you plan to take it alongside your fish oil, olive oil in salad, or a meal.

• Are a biohacker or longevity enthusiast who understands how to stack supplements.

• Prefer simplicity and control. If you don’t like multi-ingredient formulas where it’s unclear which component is doing what, you’ll appreciate the singular focus here.

ProHealth vs Olivea

On paper, ProHealth lists a slightly higher hydroxytyrosol amount (25 mg vs. 20 mg of Olivea per capsule). But the real question isn’t how much hydroxytyrosol you swallow, it’s how much your body actually absorbs. And this is where Olivea capsules clearly outperforms.

Hydroxytyrosol is a lipid-loving (fat-soluble) polyphenol, that’s why Olivea is formulated exactly this way: each dose is suspended in clinically-verified extra virgin olive oil, which acts as a natural carrier and dramatically improves intestinal uptake.

ProHealth’s capsules, while high-dose, rely on a dry extract without a built-in lipid delivery system, meaning absorption can vary substantially and may depend on whether the user takes it with the right fats at the right time. Without consistent fat co-ingestion, a meaningful portion of those 25 mg may never be fully utilized.

That said, ProHealth is excellent for certain users, especially when used correctly. But for many people, Olivea EVOO and Hydroxytyrosol Supplement wins head-to-head, considering ease of use, formulation expertise, and consistent delivery.

4. Bulletproof Superfood Antioxidants – Best Multi-Antioxidant Blend

Active Ingredients 

Bulletproof Superfood Antioxidants is a broad-spectrum polyphenol blend featuring extracts from nine different plants. Its formula reads like a “who’s who” of superfoods: pomegranate fruit extract, turmeric root (curcumin) extract, green tea leaf extract (decaf), along with a medley of berry and botanical concentrates such as blueberry, apple, chokeberry (aronia), grape skin and seed (MegaNatural®), bitter orange, and more. Notably, it includes patented high-absorption forms—Longvida® curcumin (a curcumin formulation known for crossing the blood-brain barrier) and Pomella® pomegranate extract.

Each daily serving is 4 capsules, providing a robust dose of these plant antioxidants. The product is caffeine-free, sugar-free, and keto-friendly. No synthetic vitamins here, just plant extracts standardized for their bioactive polyphenols.

Key Antioxidant Benefits

• Comprehensive Free Radical Defense: By combining nine antioxidant sources, this supplement addresses a wide range of oxidative stress in the body. The berries (blueberry, chokeberry, grape) deliver anthocyanins for vascular and eye health; green tea gives EGCG for metabolic and cellular protection; turmeric contributes curcuminoids for systemic inflammation relief. The synergy means you’re covering both water-soluble and fat-soluble antioxidants, potentially neutralizing free radicals in many tissues.

• Longevity and Cognitive Support: Longvida® curcumin is chosen for its ability to support brain health. Curcumin has neuroprotective effects but normally poor bioavailability, so Longvida solves that. Users may experience sharper cognitive function or reduced brain fog due to the combined effect of curcumin, green tea EGCG, and other polyphenols improving neural blood flow and reducing neuroinflammation.

• Metabolic and Energy Benefits: The inclusion of decaffeinated green tea extract still provides catechins that aid metabolism and mitochondrial function, without the stimulant effect. Turmeric supports healthy insulin sensitivity. Many users take these capsules in the morning to help maintain steady energy and reduce oxidative byproducts of metabolism throughout the day. Essentially, it’s like eating a basket of superberries and spices daily, which can contribute to feeling healthier and more energized.

Why Bulletproof Superfood Antioxidants for Antioxidant Support

This supplement shines for those who want an “all-in-one” antioxidant regimen. Rather than juggling separate pills for turmeric, green tea, grapes, etc., Bulletproof has combined them into one product. The use of proven patented extracts (Longvida®, Pomella®) shows they targeted both potency and bioavailability in the design.

Bulletproof is a brand known for catering to keto and wellness enthusiasts, so they ensured this formula is keto-friendly, gluten-free, and contains no junk additives. It fits well into modern diets focused on brain and body performance. If you’re someone who already eats well but wants to cover your bases with extra polyphenols, this is appealing—you get a “rainbow” of antioxidants in a few capsules.

Bulletproof encapsulated that philosophy for those aiming to hack aging and stay “bulletproof” against oxidative stress.

Pros & Cons of Bulletproof Superfood Antioxidants

Who Is Bulletproof Superfood Antioxidants For?

This product is a great match for individuals who want a one-stop-shop antioxidant solution. Consider it if you:

• Are a busy professional or parent who can’t fuss with multiple supplements.

• Follow a Bulletproof, keto, or general wellness lifestyle. This fits into a supplement stack aimed at peak performance, especially for brain and aging.

• Are concerned about chronic inflammation or toxin exposure. This blend’s variety can provide a buffer.

• Prefer stimulant-free supplements. This formula is entirely stimulant-free, so it’s suitable even for those avoiding caffeine.

Bulletproof vs Olivea

Bulletproof offers breadth—a little bit of everything, which is excellent for general wellness. However, the focused hydroxytyrosol dose of Olivea EVOO and Hydroxytyrosol Supplement is clinically tuned for cardiovascular longevity, which tends to yield more pronounced results in that domain. For example, if someone has high LDL oxidation or borderline blood pressure, Olivea’s targeted approach may have a clearer impact than Bulletproof’s diffuse approach. Olivea gives a specific 20 mg of one of the world’s most potent antioxidants with near-perfect absorption, directly tackling heart and vascular health. Bulletproof’s capsules, while rich in variety, each contain smaller amounts of each antioxidant, so beneficial, but potentially not at the therapeutic threshold individually.

For a consumer deciding between them, it comes down to goals. General prevention and convenience? Bulletproof is great. Maximizing specific longevity pathways (like the olive polyphenol route)? Olivea EVOO and Hydroxytyrosol Supplement is superior. In our analysis, if the aim is extending healthy lifespan and protecting the most critical aging organs (i.e. heart, brain) with the best evidence, Olivea emerges as the stronger choice.

5. Codeage Polyphenols Broad Spectrum – Best Antioxidant for Everyday Defense

Active Ingredients

Codeage Polyphenols Broad Spectrum is a 15-in-1 plant polyphenol supplement designed for daily wellness. Its formula features 15 different polyphenol-rich fruits and botanicals. Key players include organic decaf green tea extract, quercetin, turmeric root, olive leaf, grape seed, acai berry, pomegranate, blueberry, celery stalk, noni fruit, and more. Essentially, it blends a spectrum of well-known antioxidants from greens, berries, and herbs.

Key Antioxidant Benefits

• Daily Whole-Body Protection: With 15 different polyphenols, this supplement is all about everyday defense. The variety ensures that most organ systems receive some antioxidant support. Taken daily, it helps maintain an overall balance, preventing free radicals from accumulating and causing damage.

• Convenient Nutritional Insurance: If your diet is less than perfect on a given day, these capsules can fill the gap by providing polyphenols from greens (tea, olive, celery), fruits (berries, pomegranate) and spices (turmeric). This can result in subtle benefits like more stable energy, fewer inflammatory flares, and better recovery from exercise or stress.

• Immune & Detox Support: Ingredients like noni, olive leaf, and quercetin have antimicrobial or immune-modulating properties. Noni and olive leaf, for example, have traditional uses for infections. Meanwhile, green tea and turmeric support liver detox pathways. Daily intake might strengthen your immune resilience and help your body handle daily toxins more efficiently. Many users choose this product during cold/flu seasons or when traveling, as a natural shield.

• Healthy Aging & Skin Glow: A 2022 study found that natural polyphenols were found to improve skin appearance by reducing oxidative stress and protecting skin cells from damage. Ingredients in this blend, such as resveratrol and vitamin C, can support skin health primarily by protecting collagen through their antioxidant effects. Regular consumption of these polyphenols may contribute to maintaining healthy skin texture, joint function, and arterial health as part of an overall anti-aging approach. However, the extent of these benefits depends on formulation, dosage, individual factors, and consistent use over time.

Why Codeage Polyphenols Broad Spectrum for Antioxidant Support

Codeage’s Broad Spectrum formula is tailored for the everyday health-conscious individual who wants robust protection without juggling many products. It’s arguably the most comprehensive polyphenol blend among our picks, with one of the longest ingredient lists of plant extracts. This “kitchen sink” approach ensures you get a little of everything, and importantly, Codeage emphasizes quality. The green tea is organic and decaf, so you get the antioxidants without caffeine, which is good for daily use any time. The product is also USDA Organic certified for several components and avoids common allergens, making it accessible to most people’s lifestyles.

Pros & Cons of Codeage Polyphenols Broad Spectrum

Who Is Codeage Polyphenols Broad Spectrum For?

This supplement is ideal for those seeking everyday preventive care. You should consider Codeage if you:

• Want a broad safety net. Perhaps you’re in your 20s, 30s, or 40s and in generally good health, and you want to keep it that way.

• Don’t eat enough fruits/veggies. If you know your diet is lacking in colorful plant foods, these capsules can help supply the missing phytonutrients.

• Have multiple mild health goals. Because it’s broad, you might see subtle improvements across various areas, rather than a dramatic change in one thing.

• Are sensitive to stimulants or high doses. There’s no caffeine here, and everything is balanced.

Codeage vs Olivea

When pitting Codeage’s broad approach against the focused one of Olivea, consider depth vs breadth again. Codeage gives you a sprinkling of many polyphenols daily, great for general wellness. But Olivea provides a clinical-depth dose of one polyphenol from hydroxytyrosol that’s exceptionally powerful, especially for cardiovascular longevity. If your primary goal is to achieve specific anti-aging effects (like arterial plaque reduction or cognitive protection as seen in olive oil studies), Olivea’s singular potency is more likely to move the needle significantly.

Additionally, bioavailability and synergy differ: Codeage has no built-in fat or bio-enhancers, so taking it with food is important. Olivea EVOO and Hydroxytyrosol Supplement inherently solves absorption for its content by using olive oil and a novel delivery method. Furthermore, Olivea’s hydroxytyrosol is standardized and proven—you know you get 20 mg daily, which evidence suggests is beneficial. Codeage’s blend is not standardized to a single marker, so daily antioxidant intake might fluctuate and is less quantifiable.

6. Country Farms Super Reds – Best Value Antioxidant

Active Ingredients

Country Farms Super Reds is a powdered superfood drink mix rather than capsules. Each serving contains a blend of 48 antioxidant-rich superfoods, fruits, and berries. This impressive roster includes red fruits like raspberry, blueberry, strawberry, pomegranate, cranberry, exotic berries like goji and acai, and even vegetable extracts like beet, carrot, and tomato for additional phytonutrients. It also provides natural enzymes and fiber from ingredients such as apple fiber and flaxseed, which help absorption and digestion. Notably, beet root is a key component, contributing nitrates for circulatory health.

Key Antioxidant Benefits

• Heart and Circulation Support: The inclusion of beets and dark berries means Super Reds is excellent for cardiovascular wellness. Beets provide nitrates that help prevent cardiovascular disease and improve blood flow and oxygen delivery. The berry polyphenols help strengthen blood vessels and prevent oxidative damage to cholesterol. This can contribute to healthier blood pressure and a lower risk of arterial plaque.

• Energy and Vitality Boost: Users may feel a natural energy lift from taking Super Reds in the morning. This is likely from improved nutrient intake and circulation. The formula also contains B-vitamin ingredients and enzymes that can aid digestion, so you may feel more nourished and less sluggish.

• Immune & Detox Benefits: Loaded with antioxidants, Super Reds helps the immune system by neutralizing free radicals and reducing inflammation. Ingredients like elderberry, cranberry, and goji have traditional immune-boosting reputations.

Why Country Farms Super Reds for Antioxidant Support

Super Reds stands out for its exceptional value and convenience. For around the cost of a few fresh-pressed juices, you get a whole month’s supply of 48 superfoods. If you’re budget-conscious but still want a powerful antioxidant regimen, this is hard to beat. It’s delicious and easy to incorporate—just mix a scoop in water or a smoothie, and you’ve instantly increased your antioxidant intake for the day. This ease means you’re more likely to actually use it consistently.

Country Farms, the maker, emphasizes farm-to-table nutrition; they source natural ingredients and keep the product free of artificial colors or sweeteners. The mixed berry flavor makes it enjoyable. Users can drink it in place of an afternoon sugary drink, thereby boosting health while satisfying a sweet craving. However, it is not smart to drink it as often as drinking water.

Pros & Cons of Country Farms Super Reds

Who Is Country Farms Super Reds For?

Super Reds is perfect for:

• Students or busy professionals on a budget who want to boost their nutrition easily.

• People who dislike pills. If swallowing capsules isn’t for you, a tasty drink is a great alternative.

• Those new to supplements. If you’re just starting a health regimen, this is a gentle, food-like introduction.

• Anyone with a sweet tooth trying to cut down on junk. Because it tastes fruity and sweet without real sugar, it can replace a high-calorie snack or dessert with something beneficial.

• Fitness enthusiasts for recovery. The nitrates from beets and antioxidants from berries can aid workout performance and recovery. However, while it can help, it is not a guaranteed effect.

Super Reds vs Olivea

Super Reds covers a wide array of antioxidants in modest amounts, which is fantastic for general wellness and is very accessible. Olivea EVOO and Hydroxytyrosol Supplement, on the other hand, gives a pharmaceutical-grade dose of one of the most potent antioxidants from hydroxytyrosol in a clinically effective delivery. If we’re talking pure antioxidant power, Olivea’s hydroxytyrosol content in one capsule likely exceeds the total antioxidant capacity of a scoop of Super Reds. Remember, hydroxytyrosol has one of the highest ORAC values known.

Additionally, Olivea’s impact on critical health metrics (cholesterol oxidation, arterial health) will be more direct and pronounced than Super Reds, which is more of a general tonic. Super Reds shines in improving dietary diversity and baseline nutrition; it’s like ensuring you eat your 5-a-day in a pinch. Olivea shines in therapeutic application, almost like a natural medicine for longevity.

Another factor is consistency and formulation: Olivea gives the same dose every day with maximum absorption. With Super Reds, the actual polyphenol content might vary by scoop measurement or how well you mix it, and not every compound may be at effective doses each day, although cumulatively beneficial. And while Super Reds is superb for its cost, Olivea is an investment delivering targeted results that a cheaper blend simply can’t replicate at the same level.

7. NOW Extra Strength Grape Seed – Best Antioxidant for Cellular & Tissue Protection

Active Ingredients

NOW Foods Extra Strength Grape Seed extract provides 250 mg of Vitis vinifera (grape seed) extract per capsule, standardized to 90% polyphenols (including oligomeric proanthocyanidins, OPCs).

Aside from the grape seed extract, the only other ingredients are the veg capsule and typical minimal fillers, like rice flour or stearate, as is common with NOW’s supplements. It’s vegetarian/vegan and free of common allergens. Essentially, you’re getting a concentrated dose of grape-derived antioxidants equivalent to what you’d find in a large amount of grape seeds.

Key Antioxidant Benefits

• Connective Tissue & Skin Health: Grape seed extract works two ways: it reinforces your body's collagen structure while fighting the oxidative damage that breaks it down. This dual protection strengthens blood vessel walls and supports healthy circulation – benefits recognized for generations. You'll find visible skin improvements too: firmer texture, better elasticity, and fewer aging signs. In a 12-week clinical trial, topical application of grape seed extract with hyalurosome vesicles improves skin hydration and enhances cell viability.

• Cellular Protection: OPCs are potent scavengers of hydroxyl and peroxyl radicals, providing broad cellular defense. They can enter the bloodstream and distribute into tissues, even crossing the blood-brain barrier to some extent. This helps safeguard cells from DNA damage and lipid peroxidation. Over time, this can mean a lower risk of degenerative changes and a supportive effect on longevity at the cellular level.

• Heart & Circulation Support: Grape seed extract supports cardiovascular health in multiple ways. It helps protect LDL cholesterol from oxidation (a key step in atherosclerosis). It also promotes vasodilation by enhancing nitric oxide production, which can aid healthy blood pressure. A 16-week clinical trial found that grape seed extract supplementation reduced systolic and diastolic blood pressure.

• Tissue Repair & Recovery: Because OPCs help stabilize collagen and reduce capillary leakage, they aid the body’s recovery processes. Bruises may resolve faster, injuries might heal better due to improved microcirculation.

Why NOW Extra Strength Grape Seed for Antioxidant Support

NOW Foods is a long-trusted brand in the supplement industry, known for quality at an affordable price. Their Extra Strength Grape Seed is a standout for anyone specifically looking to protect and strengthen their tissues and blood vessels.

Moreover, the product is simple and hypoallergenic. There’s no fancy blend—just grape seed extract. That means it’s easy to fit into an existing regimen without overlap or unwanted extras. If you’re, say, already taking vitamin C or other antioxidants, adding this gives you the grape OPC benefits without doubling up on things you don’t need.

Pros & Cons of NOW Extra Strength Grape Seed

Who Is NOW Extra Strength Grape Seed For?

Consider this supplement if you:

• Are concerned about skin aging, spider veins, or loss of firmness, grape seed’s OPCs are your friend.

• Have a family history of vascular issues. Such as varicose veins or cardiovascular problems.

• Are an athlete or physically active. It can support recovery by reducing oxidative stress and inflammation in tissues after exercise.

• Prefer a targeted approach. You already take a multivitamin or other general supplements, and you want to add one specific powerful antioxidant without overlap.

NOW Grape Seed vs Olivea

While grape seed extract is fantastic, when comparing it to Olivea EVOO and Hydroxytyrosol Supplement, there are differences in potency and scope. Hydroxytyrosol is a smaller molecule with higher antioxidant capacity (ORAC) and broad effects, particularly on heart health. Grape seed OPCs excel at structural protection (collagen, vessels) and certainly have cardiovascular benefits, but hydroxytyrosol is directly linked with the Mediterranean diet’s longevity effects and can cross into the brain more easily.

One key point: hydroxytyrosol is highly bioavailable and active at low concentrations, whereas OPC absorption can be variable as they’re larger molecules that gut bacteria often metabolize. Olivea’s hydroxytyrosol in EVOO likely hits the bloodstream rapidly and acts on arteries, whereas grape seed’s OPCs, while powerful, might not all get absorbed intact. Olivea’s direct impact on reducing LDL oxidation and improving cholesterol profiles is well-documented; grape seed also does this, but in head-to-head, hydroxytyrosol might be more potent per mg.

For pure cellular antioxidant power and longevity signaling, Olivea has an edge. Also, Olivea’s hydroxytyrosol benefits include significant reductions in heart attack and stroke risk when taken regularly.

If choosing one, and the goal is overall longevity and oxidative stress reduction, Olivea is the more comprehensive and clinically backed choice. It’s the clear victor for core anti-aging outcomes, whereas grape seed is somewhat more niche in its strengths. Therefore, Olivea wins as the superior antioxidant for lifespan and healthspan extension, while grape seed remains a superb adjunct or a more affordable alternative focusing on tissue protection.

8. Barlean’s Olive Leaf Complex – Best Antioxidant for Natural Detox Support

Active Ingredients

Barlean’s Olive Leaf Complex is a liquid olive leaf extract providing a broad spectrum of olive’s beneficial compounds. Each 15 mL tablespoon delivers about 95 mg of oleuropein (standardized close to 40% oleuropein content) along with naturally-occurring amounts of hydroxytyrosol, tyrosol, verbascoside, luteolin, and other olive polyphenols.

Each dose also contains trace amounts of other olive constituents like flavonoids. It’s free of sugar, gluten, and artificial ingredients. Notably, Barlean’s also offers this complex in softgel form, but the liquid is the most popular for its versatility and faster absorption.

Key Antioxidant Benefits

• Immune System Booster & Detox: A 2023 study found that two varieties of olive leaf extracts showed antioxidant and antiviral properties, which makes it a good source for supporting cellular health and immune defense mechanisms.

• Anti-Inflammatory & Cleansing: By delivering oleuropein and hydroxytyrosol together, this liquid reduces systemic oxidative stress and inflammation. It also supports liver function indirectly by reducing these stressors. The term “detox support” applies because as it helps eliminate unwelcome microbes and reduces inflammation, your elimination pathways (liver, kidneys, lymph) can work more efficiently.

• Heart and Metabolic Benefits: Olive leaf can help maintain healthy blood pressure and blood sugar. Oleuropein has vasodilatory effects – many find that taking this complex leads to more normalized blood pressure readings over time. It also can improve insulin sensitivity.

• Quick Absorption and Flexible Dosing: Because it’s liquid, the polyphenols are already dissolved and can absorb faster than pills. Some people even take smaller doses spread out through the day for a steady supply.

Why Barlean’s Olive Leaf Complex for Antioxidant Support

Barlean’s product is the go-to if you prefer a natural, whole-herb approach to reaping olive’s benefits. Since it’s not just an isolated compound, you get the synergy of various olive polyphenols working together. This can provide a more gentle, holistic effect. The liquid format also means no pills to swallow and easy mixing into water or juice if desired.

Barlean’s as a brand is respected for its oils and herbal extracts. They ensure the olive leaves are processed fresh and cold to preserve enzymes and nutrients, which gives this product a sort of “raw juice” quality that some others don’t have.

For those focusing on a “cleanse” or “detox,” this Olive Leaf Complex is often in the toolkit because it’s one of the few antioxidant supplements that clearly has direct antimicrobial detox effects as well.

Pros & Cons of Barlean’s Olive Leaf Complex

Who Is Barlean’s Olive Leaf Complex For?

This is an excellent choice if you:

• Prefer liquids or have pill fatigue. You take a lot of supplements already and like the idea of sipping one of them.

• Are focused on immune health or dealing with an infection. If you catch colds often or bacterial issues, olive leaf is a time-honored remedy.

• Are doing a cleanse/detox program. It pairs well with detox diets or protocols – as it helps kill off pathogens and reduce inflammation, easing the detox load.

Barlean’s vs Olivea

Barlean's offers breadth with its whole olive leaf extract, delivering immune support and antimicrobial benefits from oleuropein. But when it comes to concentrated longevity power, Olivea EVOO and Hydroxytyrosol Supplement operate in an entirely different league. Here's the reality: Olivea provides 20 mg of hydroxytyrosol per capsule—you'd need approximately 27 servings of Barlean's liquid to match that concentration.

For cardiovascular protection and serious antioxidant capacity, this potency gap matters profoundly. Olivea's targeted hydroxytyrosol dose dramatically outperforms in raising blood antioxidant levels and reducing oxidized LDL—the measurable health markers that predict long-term outcomes. While Barlean's offers broad olive benefits in a dilute form, Olivea delivers the most potent compound from the olive in a format engineered for near-perfect absorption.

Practicality also favors Olivea decisively. One small, tasteless capsule requires no refrigeration and fits seamlessly into any routine—the kind of effortless compliance that actually sustains long-term results. Barlean's liquid, despite its quality, demands measuring, refrigeration, and taste tolerance that can derail consistency over months.

Barlean's certainly has its place for those prioritizing antimicrobial support or preferring liquid formats. But for readers seeking maximal anti-aging effects, cardiovascular protection, and longevity optimization, Olivea is unambiguously the superior choice.

9. Gundry MD Vital Reds – Best Vegan/Plant-Based Antioxidant

Active Ingredients

The core is the Polyphenol Blend: a mix of red and purple fruits such as blueberries, strawberries, cranberries, mulberry, blackcurrant, aronia, acai, grapeseed, pomegranate, and more—basically an anthology of superfruits.

Then there’s a Metabolic Boosting Blend with natural ingredients like cinnamon bark, ginger root, green tea extract (decaf), bitter melon, and black pepper fruit (to enhance nutrient absorption).

Lastly, a Probiotic Blend provides about 3 billion CFUs from Bacillus coagulans and strains of Lactobacillus and Bifidobacterium to support gut health.

Key Antioxidant Benefits

• Boosted Energy and Metabolism: Some of the key ingredients are found to provide metabolic support. Green tea improves lipid metabolism, cinnamon aids blood sugar control, and ginger/pepper can rev up digestion.

• Improved Digestion and Nutrient Absorption: The inclusion of probiotics means Vital Reds supports gut health. A healthy gut microbiome can reduce oxidative stress and inflammation throughout the body. This supplement can improve digestion and reduce bloating. Plus, a healthy gut enhances absorption of all those polyphenols. The black pepper extract (piperine) specifically boosts absorption of certain antioxidants like curcumin and others in the blend. So, you’re not just ingesting nutrients – you’re utilizing them better, which amplifies their antioxidant effects systemically.

• Cardiovascular and Skin Health: The rich berry polyphenols (from grape, aronia, pomegranate, etc.) benefit blood vessels and skin. They improve endothelial function and reduce oxidative damage in blood vessels, which can lead to better circulation and blood pressure. Skin benefits as well – users have noted improved skin clarity and glow. This makes sense as antioxidants from within reduce skin inflammation and protect collagen.

• Weight Management & Anti-Aging: Another angle is that by combining metabolism boosters with antioxidants, Vital Reds help combat two issues of aging: slowing metabolism and increasing oxidative damage. The result can be subtle improvements in body composition (easier to lose fat when paired with diet) and a general youthful feeling. Probiotics also help by aiding digestion and possibly improving hormonal balance related to weight. While not a weight-loss product per se, the synergy of better metabolism and lower oxidative stress often leads to feeling lighter and more youthful.

Why Gundry MD Vital Reds for Antioxidant Support

Vital Reds is like an all-in-one wellness drink formulated by a renowned heart surgeon, Dr. Gundry. The philosophy behind it is that polyphenols plus probiotics equals a thriving gut and body. If you’re a vegan or plant-based eater, this fits perfectly as it’s entirely plant-derived yet covers bases that some plant-based diets lack (like certain polyphenols from exotic fruits you might not get often, or probiotics usually found in yogurt). It’s 100% vegan, which earns it the title of best plant-based antioxidant blend here.

Gundry MD emphasizes quality and purity. There are no artificial sweeteners (just stevia and natural flavors) and no synthetic vitamins thrown in. For those wary of mass-market supplements, Gundry’s brand promises a higher standard and is often backed by his research and guarantee.

Users often love that Vital Reds tastes good – it’s like a mildly sweet berry juice. This makes compliance easier: you actually look forward to your daily glass.

Pros & Cons of Gundry MD Vital Reds

Who Is Gundry MD Vital Reds For?

Vital Reds is a great fit if you:

• Want a comprehensive wellness supplement but hate pills. Vital Reds is about as close as it gets in covering multiple bases.

• Follow a plant-based or vegan diet. It ensures you’re getting a broad array of plant nutrients (even exotic ones) and beneficial bacteria not found in vegetables.

• Feel low on energy or have stubborn weight. If you suspect your metabolism is slow or your energy dips in the afternoon, the metabolic blend here might help. Effects vary for each user, however.

• Care about gut health. If you experience occasional bloating, irregularity, or you just know the importance of the gut, the probiotics plus polyphenols will appeal to you.

Gundry MD vs Olivea

Vital Reds and Olivea EVOO and Hydroxytyrosol Supplement may both support wellness, but they are built for completely different outcomes—and only one is engineered for true, measurable longevity benefits. Vital Reds is a “feel-good” blend: a little energy, a little gut support, a wide sweep of berries and botanicals. It’s a general pick‑me‑up.

Olivea, on the other hand, delivers a clinically validated, high‑impact dose of hydroxytyrosol, which is one of the most powerful antioxidants ever studied for vascular, cellular, and longevity protection. Its benefits are documented in human research, Mediterranean‑diet epidemiology, and EFSA‑approved health claims.

Where Vital Reds helps you feel more energized, Olivea helps ensure your heart, arteries, cells, and even your DNA are better protected for the long haul. Hydroxytyrosol has been shown to reduce LDL oxidation, improve endothelial function, lower chronic inflammation, and support healthy blood pressure.

Put simply: Vital Reds helps you feel good today. Olivea EVOO and Hydroxytyrosol helps you stay healthy for decades. Vital Reds is broad, light, and lifestyle-focused. Olivea is precise, potent, and built for real longevity science.

10. Integrative Therapeutics Cortisol Manager – Best Antioxidant for Stress Relief & Recovery

Active Ingredients

Cortisol Manager by Integrative Therapeutics is a specialized formula aiming to reduce stress and balance cortisol levels. Its key ingredients include a proprietary blend of adaptogenic herbs: Sensoril® Ashwagandha (Withania somnifera extract)—a patented, clinically-studied form of ashwagandha and L-Theanine—an amino acid from green tea known for promoting relaxation.

Additionally, it contains a blend of Magnolia bark extract and Epimedium extract, along with a small amount of Phosphatidylserine (from soy lecithin). These support healthy adrenal response and calmness.

Key Antioxidant Benefits

• Reduces Stress-Related Oxidative Damage: Chronic stress elevates cortisol, which over time can increase inflammation and free radical production in the body. By helping normalize cortisol levels, Cortisol Manager indirectly reduces the oxidative stress that high cortisol can cause. Ashwagandha in particular has been shown to lower cortisol in stressed adults. Lower stress = lower systemic inflammation = less oxidative damage to cells.

• Improves Sleep Quality & Recovery: The combination of ashwagandha and L-theanine promotes relaxation and can improve sleep depth. Quality sleep is when our body’s antioxidant defenses (like melatonin, glutathione) peak and repair happens. Sleep is the ultimate antioxidant, in a sense, and Cortisol Manager helps you harness that natural process.

• Enhances Mood & Cognitive Function: High stress can impair memory and cognitive function by oxidative mechanisms in the brain. By using L-theanine, which some studies suggest increases alpha brain waves, inducing a relaxed but alert state, and ashwagandha, Cortisol Manager can sharpen focus and reduce anxious feelings in the day.

• Supports Adrenal Health & Hormonal Balance: Over time, high cortisol can wreak havoc on the adrenal glands and hormones, like DHEA, which is a longevity hormone that drops under stress. By controlling nighttime cortisol spikes and flattening abnormal cortisol curves, this supplement helps maintain a healthier diurnal rhythm. That equates to more stable energy, better metabolism, and even normal appetite.

Why Integrative Therapeutics Cortisol Manager for Antioxidant Support

It might seem odd to include a “stress supplement” in an antioxidant list, but it makes perfect sense—stress is one of the silent agers. Cortisol Manager by Integrative Therapeutics is arguably the top stress relief formula on the market, often recommended by integrative doctors for patients with burnout or sleep issues. It earned the spot of “best for stress relief & recovery” because reducing stress has a compounding positive effect on every aspect of health, including how well our bodies handle oxidative stress and repair damage.

Integrative Therapeutics ensures that their formula is evidence-based: Sensoril Ashwagandha is clinically studied. For example, a 2021 systematic review of seven studies found that ashwagandha reduced the stress and anxiety levels of participants in the reviewed studies.

Pros & Cons of Integrative Therapeutics Cortisol Manager

Who Is Integrative Therapeutics Cortisol Manager For?

Consider Cortisol Manager if you:

• Have a busy job and many family responsibilities, or just internal anxiety.

• Exercise andfeel perpetually sore or fatigued, or you notice that even small stresses knock you out, your cortisol might be imbalanced.

• Have insomnia, especially stress-related, or irregular sleep patterns could benefit. It’s a gentler alternative to sleeping pills and helps address the root (stress hormones) rather than just sedating you.

• Want to focus on anti-aging. People don’t often realize chronic cortisol breaks down collagen (causing wrinkles), leaches bone, and impairs immunity. If you’re already taking care of diet and skincare, etc., but ignoring stress, you’re missing a piece..

Integrative Therapeutics vs Olivea

The strength of Olivea EVOO and Hydroxytyrosol Supplement is directly fighting oxidative stress with a potent compound, hydroxytyrosol. Cortisol Manager’s strength is reducing the source of a lot of oxidative stress—chronic cortisol and poor sleep.

In terms of immediate measurable antioxidant impact, Olivea wins. You could see effects like lower oxidized LDL or higher antioxidant capacity in blood with Olivea. Cortisol Manager won’t show that directly, but in a person with high stress, after using it, you might see indirect improvements: better sleep leads to lower inflammatory markers, etc. However, those are less directly tied and can vary.

For longevity, ideally one would use both: manage stress and take potent antioxidants. But if we have to pick the “clear winner” in a head-to-head for an antioxidant product list, Olivea EVOO and Hydroxytyrosol would edge out because it is explicitly an antioxidant-rich supplement with concrete, broad physiological benefits.

So, while Cortisol Manager is incredibly valuable (indeed, perhaps undervalued in how big an impact stress reduction has on aging), Olivea stands as the more directly impactful and “visible” champion in an antioxidant lineup. Therefore, Olivea remains the winner overall, but with the wise note that combining a product like Cortisol Manager with Olivea could give a one-two punch to both causes and effects of oxidative aging.

11. Terry Naturally CuraMed 750 mg – Best Allergen-Free Antioxidant

Active Ingredients

CuraMed 750 mg is a potent curcumin (from turmeric) supplement produced by Terry Naturally (also known as EuroPharma). Each softgel contains 750 mg of a curcumin complex called BCM-95® (also marketed as Curcugreen®), which is a unique blend of curcumin extract and turmeric essential oils for enhanced absorption.

CuraMed is free of common allergens – it’s non-GMO, gluten-free, and contains no yeast, dairy, or artificial sweeteners.

Key Antioxidant Benefits

• Powerful Inflammation Fighter: Curcumin is one of the most studied natural anti-inflammatories. By inhibiting NF-κB and COX-2, it helps reduce the production of inflammatory cytokines. This translates to relief in conditions like joint pain, muscle soreness, and overall chronic inflammation. Less inflammation means less oxidative stress (since inflammation generates free radicals).

• Cellular Protection & Detox: Curcumin is a strong antioxidant in its own right – it directly scavenges free radicals and upregulates the body’s own antioxidant enzymes. A 2020 systematic review of four clinical trials found that curcumin can boost the body’s overall antioxidant capacity, which can help protect against oxidative stress.

• Heart and Brain Health: Curcumin’s antioxidant and anti-inflammatory powers benefit the cardiovascular system, improving endothelial function and possibly helping keep arteries clear by reducing oxidative modifications of fats. For the brain, curcumin crosses the blood-brain barrier and has shown promise in supporting cognitive health. It may help clear or prevent buildup of oxidized proteins in the brain.

• Allergen-Free & Gentle on Stomach: As an allergen-free formula, CuraMed is ideal for those who can’t take common supplements due to fillers (some vitamin C or E supplements have soy, gluten, etc., which this doesn’t). Curcumin itself can sometimes cause stomach upset in very high doses, but BCM-95’s inclusion of turmeric oils often actually eases digestion. And since you only need one softgel for a potent dose, it’s easy on the regimen.

Why Terry Naturally CuraMed 750 mg for Antioxidant Support

Terry Naturally’s CuraMed is often hailed as the gold standard of curcumin supplements. The fact that one softgel provides a clinical dose of curcumin that stays in the blood for hours means you’re truly reaping curcumin’s benefits (whereas raw turmeric or cheap curcumin might be mostly unabsorbed).

For someone looking for a strong natural antioxidant but who might have had issues with other supplements (due to allergies or additives), CuraMed is a perfect find. It is free of allergens and extremely pure.

Another key reason is that curcumin covers many bases: it’s an antioxidant, anti-inflammatory, and even supports glutathione production. Some antioxidants only scavenge free radicals (like vitamin C), but curcumin actually orchestrates a better antioxidant response in the body.

Pros & Cons of Terry Naturally CuraMed 750

Who Is Terry Naturally CuraMed 750 mg For?

CuraMed is ideal if you:

• Suffer from chronic inflammation or pain. Those with arthritis, back pain, or autoimmune conditions often use curcumin to find relief.

• Want a potent antioxidant but have allergies. If you’ve had issues with vitamin supplements or formulas that contain soy, dairy, gluten, etc., CuraMed offers a potent alternative without those triggers.

• Are concerned about brain aging or cognitive support. Those with a family history of neurodegenerative diseases or who want to maintain cognitive health might choose CuraMed as part of their regimen.

• Prefer minimal pills, because one softgel packs a punch, it’s good for those who don’t want to take multiple capsules throughout the day. Dosage is typically 1 softgel once or twice daily, which is convenient.

Terry Naturally vs Olivea

When it comes to powerful antioxidant supplements, Olivea EVOO & Hydroxytyrosol clearly emerges as the better choice, especially if longevity, heart health, and youthful aging matter most to you. Hydroxytyrosol, Olivea’s active compound, is more than just another antioxidant. It’s an exceptional longevity molecule, directly linked by extensive research to reduced heart disease risk, improved vascular health, lower inflammation, and overall healthier aging outcomes. Derived straight from the renowned Mediterranean diet, Olivea brings a clinically validated, targeted dose of 20mg per capsule of hydroxytyrosol.

Unlike curcumin, which broadly targets inflammation across multiple body systems, Olivea’s hydroxytyrosol specifically and powerfully tackles oxidative stress at its root, protecting your arteries, blood lipids, and even your DNA from daily damage. While curcumin is a valuable generalist, hydroxytyrosol acts with laser precision, making Olivea an ideal daily regimen for anyone serious about cardiovascular longevity, radiant skin, and sustained cognitive function.

Additionally, Olivea’s advanced capsule-in-capsule EVOO delivery maximizes bioavailability, ensuring your body truly benefits from its extraordinary antioxidant potency.

Curcumin has undeniable merit, yet for focused, proven longevity benefits supported by robust human studies, Olivea EVOO & Hydroxytyrosol stands unmatched. It isn’t merely a supplement; it’s an evidence-backed investment in your long-term health and vitality.

12. Solgar Ester-C Plus – Best Antioxidant for Sensitive Stomachs

Active Ingredients

Solgar Ester-C Plus is a vitamin C supplement formulated as Calcium Ascorbate (a neutral pH, non-acidic form of vitamin C) along with natural co-factors. Each tablet typically provides 500 mg or 1000 mg of Ester-C (Vitamin C), depending on the variant, and includes Citrus Bioflavonoids Complex, acerola berry, and rose hips.

Key Antioxidant Benefits

• Gentle, Ongoing Immune Support: Vitamin C is a cornerstone antioxidant for the immune system, protecting immune cells from free radicals generated during fighting infections. Ester-C’s unique metabolites help it stay in immune cells for up to a day, which means round-the-clock immune support with fewer doses. People with sensitive stomachs can take higher doses of Ester-C without gastric irritation, making it possible to use vitamin C therapeutically (like 1000 mg 2x daily during colds) comfortably. This continuous presence of C helps maintain a robust immune defense and quick recovery from illness.

• Collagen Formation & Skin Health: Vitamin C is required for collagen synthesis. It literally helps “cement” collagen fibers. Ester-C provides ample C for your body to produce collagen, benefiting skin elasticity, wound healing, gum health, and joints. Those with sensitive stomachs might avoid high citrus or ascorbic acid intake (due to acid), so Ester-C allows them to get collagen-supporting doses without reflux or upset. Over time, this can lead to healthier, more youthful skin and stronger connective tissues (less bruising, etc.).

• Alkaline and Stomach-Friendly: Traditional vitamin C (ascorbic acid) in high doses can cause heartburn or diarrhea due to its acidity. Ester-C is non-acidic, so even at gram-level doses it’s more tolerated, a boon for those with acid reflux or sensitive GI tracts. A calm stomach means you can consistently take an antioxidant dose that saturates your body’s tissues (consistency is key for antioxidant benefits).

Why Solgar Ester-C Plus for Antioxidant Support

Solgar is a respected brand with a long history of quality, and their Ester-C Plus stands out because it addresses one of the main drawbacks of high-dose vitamin C: acidity. By providing a form of C that is pH neutral and accompanied by natural co-factors, it’s arguably one of the best thought-out vitamin C supplements for holistic health support. The inclusion of bioflavonoids, acerola, and rose hips means you get a boost similar to eating vitamin C-rich fruits, not just isolated ascorbate.

For someone aiming to fight oxidative stress, vitamin C is fundamental: it recycles vitamin E, regenerates glutathione, and directly scavenges radicals. Ester-C’s extended retention in the body means you have antioxidant protection even hours after taking it (24-hour presence in white blood cells has been cited by Solgar and studies). This can be particularly beneficial for older adults, who often have lower vitamin C status.

Pros & Cons of Solgar Ester-C Plus

Who Is Solgar Ester-C Plus For?

This is the go-to vitamin C for:

• Individuals with sensitive stomachs or GERD. If normal vitamin C gives you acid reflux, or you avoid orange juice due to acidity, Ester-C lets you supplement C without those issues.

• Those wanting consistent immune support. If you tend to catch colds or want to bolster your immune system.

• People with periodontal or skin concerns: Since C is crucial for gum health and skin collagen, anyone noticing bleeding gums or wanting to improve skin healing (post-surgery recovery, for instance) would benefit.

• Vegans/Vegetarians. They often rely on vitamin C for iron absorption from plant foods.

Solgar vs Olivea

When comparing Ester‑C to Olivea EVOO and Hydroxytyrosol Supplement, the difference becomes clear: one offers basic daily support, while the other delivers true, measurable longevity benefits. Vitamin C is universally important, but most people already consume enough from food to prevent deficiency. Increasing intake helps immunity and collagen production, but the body can only absorb so much before excreting the rest. It is foundational—yet limited.

Olivea, however, provides something the typical diet cannot: a clinically validated dose of hydroxytyrosol, one of the most powerful polyphenols found in nature and a star of the Mediterranean diet’s proven longevity effects. Research shows hydroxytyrosol protects LDL cholesterol from oxidation, improves arterial function, reduces systemic inflammation, supports blood pressure health, and enhances cellular resilience. These are the exact mechanisms that slow biological aging and prevent the most common age‑related diseases. Its power per milligram far surpasses vitamin C, and its benefits extend deeply into vascular health, cognitive function, skin aging, and long‑term vitality.

Ester‑C is helpful, especially for sensitive stomachs, but Olivea is transformative. If vitamin C is the “baseline,” Olivea is the upgrade. It is a strategic, science‑backed investment in heart health, longevity, and graceful aging. For anyone truly serious about antioxidant protection, Olivea stands in a class of its own.

13. Bausch + Lomb PreserVision AREDS 2 – Best Antioxidant for Healthy Vision as You Age

Active Ingredients

PreserVision AREDS 2 by Bausch + Lomb is an eye vitamin based on the Age-Related Eye Disease Study 2 (AREDS2) formula, which has been clinically proven to support eye health in aging.

Each daily serving (2 softgels) contains the exact nutrients used in the AREDS2 trial: 500 mg Vitamin C, 400 IU Vitamin E, 10 mg Lutein, 2 mg Zeaxanthin, 80 mg Zinc (as zinc oxide), and 2 mg Copper (as cupric oxide). Notably, this formula does not include beta-carotene (which was in original AREDS but removed in AREDS2 due to lung cancer risk in smokers), and instead includes lutein and zeaxanthin—carotenoids that accumulate in the macula of the eye.

Key Antioxidant Benefits

• Protects Macular Health: The primary benefit is protecting the retina (specifically the macula) from oxidative damage. Lutein and zeaxanthin accumulate in the eye and act like internal sunglasses, plus antioxidants. They neutralize free radicals produced by UV and blue light exposure. For someone at risk of AMD or with early signs, PreserVision can slow the progression of vision loss. Essentially, it’s targeted antioxidant therapy for the eyes, one of the organs most susceptible to oxidative stress with age (due to constant light exposure and high metabolic rate).

• Full-Spectrum Eye Nutrients: Vitamin C and E in the formula provide broad antioxidant coverage for the entire body, including ocular blood vessels. Zinc plays a role in antioxidant enzymes like superoxide dismutase in the eye. By having these in robust amounts, the supplement not only helps eyes but provides general antioxidant benefits (C and E together also help regenerate each other). Many older adults might not get enough of these, so this supplement covers nutritional gaps that specifically relate to vision health.

• Clinically Proven Efficacy: Unlike many supplements, this exact combination has been tested in large-scale trials (AREDS, AREDS2). The evidence showed a 25% risk reduction in developing advanced AMD over 5 years. That’s significant. So the benefit is not theoretical, it’s demonstrated in tens of thousands of patients. For someone with moderate AMD, this can be the difference between maintaining vision or losing it.

• Age-Related Wellness: Even beyond AMD, the components help with overall aging. Lutein/zeaxanthin have been linked in some studies to improved cognitive function in older adults (possibly by protecting brain tissues similarly).

Why PreserVision AREDS2 for Antioxidant Support

PreserVision AREDS2 makes the list because it’s the gold standard for vision-specific antioxidant therapy. Eyesight is something many fear losing with age, and this is a proven measure one can take to maintain it. It exemplifies a scenario where targeted antioxidant supplementation (vs. diet alone) is warranted and effective, an important concept in longevity circles.

From an antioxidant perspective, it’s a great formulation: it doesn’t go overboard with dozens of ingredients, it sticks to what works in the right doses. The removal of beta-carotene (which in smokers could cause harm) shows it’s updated for safety and efficacy. They also balanced high zinc with copper to avoid anemia (smart, evidence-based tweak). So you’re getting a thoughtfully formulated product with high-quality control from Bausch + Lomb, a company known in eye care..

Pros & Cons of PreserVision AREDS 2

Who Is PreserVision AREDS 2 For?

This is for you if you:

• Have Age-Related Macular Degeneration. If you have intermediate AMD in one or both eyes (drusen present, etc.) or advanced AMD in one eye, this is for you, per your eye doctor's recommendation.

• Are over 50 with early signs of macular changes or strong family history.

• Are a smoker or an ex-smoker who needs eye support. The original formula had beta-carotene which smokers had to avoid; the AREDS2 formula is safe for smokers, so they can now take this eye-protective formula without risk.

• Are an ophthalmologist/optometrist recommended case. If your eye doctor measures low macular pigment density or otherwise thinks your diet is lacking in those eye nutrients, they might recommend it, even without AMD.

PreserVision vs Olivea

Comparing PreserVision to Olivea is like comparing a precision tool to a powerhouse, they excel in fundamentally different domains. PreserVision is laser-focused on preserving vision, particularly preventing age-related macular degeneration, backed by the landmark AREDS2 study. Its specific combination of lutein, zeaxanthin, vitamins C and E, zinc, and copper has documented efficacy for slowing AMD progression. If your primary concern is protecting your eyesight as you age, PreserVision is the evidence-based choice.

However, when evaluating broader longevity and antioxidant impact, Olivea EVOO and Hydroxytyrosol Supplement pulls decisively ahead. Hydroxytyrosol's extensive research portfolio demonstrates significant effects on cardiovascular health, arterial function, and possibly cognitive aging. addressing the leading causes of mortality like heart disease and stroke. PreserVision's ingredients, while protective for eyes, don't carry the same weight of evidence for systemic longevity benefits.

The two can certainly complement each other, and many would benefit from both: PreserVision for targeted vision protection and Olivea for comprehensive cardiovascular and cellular defense. There's no ingredient conflict, they actually fill different nutritional gaps.

But if choosing one antioxidant supplement for overall longevity, Olivea EVOO and Hydroxytyrosol Supplement is the clear winner. It directly addresses conditions that impact both lifespan and healthspan, whereas PreserVision addresses quality of life through vision preservation, crucial, but not life-extending. PreserVision remains unbeatable in its specialized niche, yet Olivea's broad, powerful impact on the systems that determine how long and how well you live makes it the superior choice for comprehensive anti-aging supplementation.

14. Life Extension Neuro-Mag – Best Antioxidant for Brain Health as You Age

Active Ingredients

Life Extension’s Neuro-Mag is a brain-focused magnesium supplement featuring Magnesium L-Threonate. Each serving (3 capsules) provides 2,000 mg of magnesium L-threonate, yielding 144 mg of elemental magnesium.

Key Antioxidant Benefits

• Cognitive Function & Memory: Adequate magnesium in the brain supports synaptic plasticity, which is crucial for learning and memory. Magnesium L-threonate has demonstrated in studies improvements in short-term and long-term memory, as well as executive function, especially in older adults.

• Neuroprotection & Brain Aging: Magnesium helps the brain age more gracefully, potentially lowering risk or delaying onset of cognitive decline by keeping neurons healthy and stress-resistant (magnesium is known to stabilize mitochondrial function and DNA repair processes too).

• Better Sleep & Stress Response: Many find that magnesium L-threonate improves sleep quality. Good sleep is one of the best antioxidants for the brain, as that’s when cleanup of toxins (like beta-amyloid via the glymphatic system) occurs. So, by enhancing sleep (magnesium is calming, helps with insomnia especially in magnesium-deficient individuals), Neuro-Mag indirectly ensures the brain gets its nightly “wash” of oxidative byproducts.

Why Neuro-Mag Magnesium L-Threonate for Antioxidant Support

Neuro-Mag by Life Extension is the top brain-health supplement in the mineral category. It’s included not because magnesium is a classic antioxidant, but because it addresses brain aging in a unique, foundational way that antioxidants do: by preserving cognitive function and preventing oxidative damage indirectly.

For anyone worried about memory loss or “senior moments”, Neuro-Mag offers a nutritional approach to head that off. It basically fills a gap: many people are magnesium deficient (common in older folks due to diet or absorption issues), and while taking magnesium oxide or citrate might help muscles, they won’t do much for the brain’s magnesium levels. Neuro-Mag is specifically solving the brain magnesium issue, which no other form does as effectively.

Pros & Cons of Life Extension Neuro-Mag

Who Is Neuro-Mag Magnesium L-Threonate For?

Neuro-Mag is ideal if you:

• Are middle-aged or older and noticing memory or learning issues. It’s practically designed for the 50+ crowd to keep their brains youthful.

• Have a family history of dementia or Alzheimer’s. As a preventative measure, ensuring optimal brain magnesium might reduce risk factors or at least delay onset.

• Suffer from brain fog or mental fatigue. Even younger individuals under high stress or intense mental workload will benefit.

• Struggle with sleep or anxiety along with wanting cognitive support. Magnesium is calming, and L-threonate crosses into the brain to potentially have an anxiolytic effect.

• Prefer to avoid heavy sedatives or stimulants. This is a nutritional approach, not a stimulant like some nootropics or a sedative.

Life Extension vs Olivea

When comparing Neuro-Mag and Olivea EVOO & Hydroxytyrosol Supplement, Olivea emerges as the superior choice for anyone serious about longevity, heart health, and overall wellness. Olivea’s hydroxytyrosol directly provides potent antioxidant protection, targeting cardiovascular health. With extensive research backing its impact, hydroxytyrosol significantly reduces oxidative stress, enhances arterial function, lowers inflammation, and directly addresses leading causes of mortality, including heart attacks and strokes.

Neuro-Mag, while valuable, is not actually an antioxidant. It indirectly protects the brain by supporting cognitive function through improved magnesium levels. This approach is beneficial for brain aging and preserving cognitive independence, but it doesn't offer the broad, powerful antioxidant protection that Olivea does. Hydroxytyrosol, Olivea’s active ingredient, penetrates cells directly, neutralizes damaging free radicals, and actively protects DNA, arteries, and skin from oxidative damage.

If you prioritize comprehensive longevity support and powerful, proven antioxidant protection, Olivea EVOO & Hydroxytyrosol clearly stands out. Neuro-Mag can complement your brain-health strategy, but Olivea remains the essential, evidence-backed foundation for true long-term wellness.

15. Purely Beneficial Resveratrol 1450 – Best Antioxidant for General Wellness Support

Active Ingredients

Purely Beneficial’s Resveratrol 1450 is a high-potency resveratrol complex claiming a total of 1450 mg per serving (2 capsules) of various polyphenols. The blend is led by Trans-Resveratrol and supported by Green Tea Extract, Grape Seed Extract (95% OPCs), Acai Berry Extract, Red Wine Extract, Pomegranate Extract, Blueberry Extract, Noni Fruit, Alfalfa, and Hawthorn Berry.

Key Antioxidant Benefits

• Cardiovascular and Longevity Support: In this supplement, a substantial dose of trans-resveratrol aims to support heart health by improving endothelial function and reducing inflammation. The added grape seed, green tea, and red wine extracts complement this by further protecting blood vessels and supporting healthy cholesterol levels.

• General Wellness & Energy: With ingredients spanning acai, noni, blueberry, etc., you’re getting a broad array of antioxidants that can improve overall vitality. The presence of vitamin C and all these fruit extracts likely supports immune function and metabolic health as well. Essentially, it’s like taking a shortcut to consuming multiple servings of berries and green tea daily.

• Anti-Inflammatory and Joint Support: Resveratrol and many of the included polyphenols have anti-inflammatory properties. Some people take resveratrol specifically for joint pain or inflammatory conditions. While not as potent as curcumin for pain, the cumulative effect of these ingredients can help reduce systemic inflammation, which might manifest as less joint stiffness or improved mobility for some, or just less CRP in blood tests.

Why Purely Beneficial Resveratrol 1450 for Antioxidant Support

Purely Beneficial’s Resveratrol 1450 earned “best for general wellness” because it’s like a multivitamin of antioxidants. It’s budget-friendly, especially considering it’s a 3-month supply in one bottle. They’ve made it a point to have no fillers and a lot of natural extracts, which appeals to the health-conscious who want potency without junk. The diversity in ingredients ensures you get both water-soluble and fat-soluble antioxidants, and ones that work in different parts of the body (green tea more in liver metabolism, grape seed in blood, resveratrol in cell nuclei, etc.).

Pros & Cons of Purely Beneficial Resveratrol 1450

Who Is Resveratrol 1450 For?

This supplement is for:

• Adults in mid-life (30s, 40s, 50s) who want to take a proactive approach to their health with one convenient product.

• People who prefer a natural cocktail over many pills. It's simpler for those new to supplements or who don't want a complex regimen.

• Those who can't drink wine but want its benefits. If you like the idea of red wine’s resveratrol but avoid alcohol or sugar, this gives you concentrated resveratrol without those downsides.

• General antioxidant maintenance. It’s for the person who wants to cover general antioxidant and anti-inflammatory support.

Purely Beneficial vs Olivea

When comparing Resveratrol 1450 to Olivea EVOO & Hydroxytyrosol Supplement, Olivea clearly stands apart as the superior choice, particularly for targeted and proven longevity benefits. While Resveratrol 1450 takes a broader approach, combining multiple polyphenols like resveratrol, green tea extract, and other antioxidants. Olivea EVOO and Hydroxytyrosol Supplement, in contrast, provides a potent, clinically validated 20 mg dose of hydroxytyrosol, directly delivering remarkable antioxidant benefits that specifically target cardiovascular health, LDL cholesterol oxidation, inflammation reduction, and cellular longevity.

For anyone committed to serious anti-aging strategies, Olivea’s laser-focused approach offers far greater potency, clarity of purpose, and clinical support than a generalized blend like Resveratrol 1450. Simply put, if your goal is robust, targeted antioxidant support backed by substantial clinical evidence and clear longevity outcomes, Olivea EVOO & Hydroxytyrosol Supplement is the undisputed winner.

Frequently Asked Questions About Antioxidants

What is the most powerful source of antioxidants?

Among supplements, concentrated olive‑derived hydroxytyrosol is emerging as one of the most powerful antioxidant sources. Studies show it penetrates cellular tissues, reduces oxidative damage, and supports cardiovascular and skin health. This positions Olivea EVOO and Hydroxytyrosol Supplement as one of the strongest options for total antioxidant support.

What are the big three antioxidants?

Traditionally, the “big three” antioxidants are vitamin C, vitamin E, and polyphenols, with hydroxytyrosol (the powerhouse polyphenol in Olivea EVOO & Hydroxytyrosol Supplement) standing out as one of the most potent and clinically supported. Olivea EVOO & Hydroxytyrosol Supplement delivers a pharmaceutical dose of hydroxytyrosol, offering far stronger cellular, cardiovascular, and skin‑protective benefits than basic vitamin antioxidants. Vitamins C and E remain important, but hydroxytyrosol is in a league of its own for longevity and vascular protection.

Is it safe to take antioxidants every day?

Yes. High‑quality antioxidants are safe to take daily when used in appropriate, evidence‑based doses. Supplements like Olivea EVOO & Hydroxytyrosol Supplement are particularly safe because hydroxytyrosol comes from olives, one of the most well‑studied and widely consumed foods in the Mediterranean diet. The key is choosing clean, well‑formulated products rather than megadosing random blends. Daily antioxidant intake can support immunity, slow aging, and protect heart and brain health

Do I really need antioxidant supplements if I eat a healthy diet?

If you already eat an abundance of fruits, vegetables, and healthy fats (like extra virgin olive oil), you’re getting plenty of natural antioxidants, which is fantastic. Supplements aren’t a replacement for a good diet, but rather an addition. People turn to these supplements either to target specific concerns or to get a concentrated dose of certain antioxidants hard to obtain from food alone, like 20 mg of hydroxytyrosol from olives. If your diet is impeccable, you may not need all of these. However, diets aren’t perfect every single day. Supplements such as Olivea EVOO and Hydroxytyrosol Supplement ensures you consistently meet high antioxidant levels.

Is it safe to take multiple antioxidant supplements together?

For most people, yes. Combinations are generally safe as long as you stay within recommended doses for each. In fact, many of the supplements above naturally complement each other.

How long does it take to notice benefits from these antioxidant supplements?

It varies by supplement and individual. Some people experience a boost in energy or mental clarity within a few weeks. For vascular benefits, such as improved blood pressure or cholesterol levels from polyphenols, you’re looking at 1-3 months of consistent use to see changes in lab tests or blood pressure readings. Eye health changes are typically long-term and preventative; you wouldn’t “feel” it working day-to-day, but over years it makes a difference in disease progression.

What is the best time of day to take these antioxidant supplements?

As a rule, fat-soluble nutrients, like the lutein & zeaxanthin in PreserVision, or curcumin in CuraMed, absorb better with food, especially a meal containing some fat. Olivea EVOO and Hydroxytyrosol Supplement capsule is inherently in oil, so you can take it anytime, but taking with a meal is fine too. Water-soluble ones (vitamin C, any B vitamins in a multi) can be taken on empty stomach if tolerated, but sometimes vitamin C empty can cause minor nausea in sensitive folks.

For some supplements, you have to consider the effects. A multi-ingredient like Resveratrol 1450 has green tea, a bit of caffeine, so morning or early afternoon is better, to avoid sleep interference. With Olivea EVOO and Hydroxytyrosol Supplement, you can do morning to start the day with a dose of longevity, or honestly whenever, there’s no stimulant or sedative effect, so it's flexible.

What Is the Best Antioxidant Supplement?

After evaluating 15 top antioxidant supplements across potency, absorption, clinical evidence, and ingredient purity, one product stands above the rest: Olivea EVOO & Hydroxytyrosol Supplement. It delivers the strongest antioxidant protection in the most absorbable form, backed by decades of Mediterranean diet research and rigorous clinical validation.

Why Olivea EVOO and Hydroxytyrosol Supplement Wins

• Unmatched Free-Radical Fighting Power: Hydroxytyrosol is one of the most potent natural antioxidants ever tested, with an ORAC value that far exceeds vitamin C, vitamin E, resveratrol, and CoQ10. It neutralizes reactive oxygen species before they can damage your DNA, oxidize your cholesterol, or degrade collagen in your skin and joints.

• Clinically Effective Dose: Each capsule delivers 20 mg of hydroxytyrosol—four times what the European Food Safety Authority recognizes as the minimum effective dose for protecting blood lipids from oxidative damage. Most competitors underdose or hide amounts behind proprietary blends.

• Absorption That Actually Works: Even powerful antioxidants are useless if they don't reach your cells. Olivea's capsule-in-capsule design suspends hydroxytyrosol in extra virgin olive oil, dramatically improving bioavailability compared to dry powder formats. You absorb what you take.

• Whole-Body Antioxidant Protection: Unlike single-target antioxidants, hydroxytyrosol works across multiple systems simultaneously—defending arteries from oxidation, protecting skin from free-radical aging, supporting brain health, reducing systemic inflammation, and promoting healthy cellular function throughout your body.

• Proven Longevity Connection: Research links higher olive polyphenol intake to 15% lower cardiovascular disease risk and 17% reduced all-cause mortality. Olivea gives you the compound behind the Mediterranean diet's remarkable health outcomes—concentrated and optimized for daily use.

• Clean, Pure Formula: Made from organic Greek olives. Non-GMO, vegan, free of fillers, artificial additives, and common allergens. Just the antioxidant and the oil that helps you absorb it.
