13 Best Olive Leaf Extract Supplements (2025 Review)

Olive leaf extract has become one of the most sought-after supplements for cardiovascular health, immune support, and healthy aging. The key compounds responsible for these benefits are polyphenols like oleuropein and hydroxytyrosol, which give olive oil its legendary health properties.

With the supplement market flooded with options in 2025, choosing the right olive leaf extract can feel overwhelming. Some products focus on high oleuropein content, others prioritize organic sourcing, and a few take innovative approaches to maximize absorption and effectiveness.

How We Rate Olive Leaf Extract Supplements

Choosing the right olive leaf supplement requires looking beyond marketing claims to understand what actually makes a difference in your body. Our evaluation process examined hundreds of products through the lens of scientific evidence, laboratory analysis, and real user outcomes. Here's what separated the exceptional from the ordinary:

Potency & Standardization

The amount of active compounds matters, but so does consistency. We prioritized supplements that clearly state their oleuropein or hydroxytyrosol content and deliver clinically meaningful doses. For context, research shows that at least 5 mg of hydroxytyrosol daily provides cardiovascular benefits according to European health authorities. Products earning top marks delivered well above minimum thresholds while maintaining batch-to-batch consistency through standardization.

Bioavailability & Delivery Method

Even the most potent supplement won't help if your body can't absorb it. We favored products with enhanced delivery systems that improve polyphenol absorption. Olivea's innovation of suspending hydroxytyrosol in extra virgin olive oil earned exceptional marks because it mimics how these compounds naturally occur in the Mediterranean diet. Liquid formulations and capsules with absorption enhancers also scored well for maximizing the amount of active compounds that actually reach your bloodstream.

Quality & Purity

We scrutinized sourcing, certifications, and manufacturing standards. Top products use Mediterranean-grown olives or certified organic sources, undergo third-party testing, and avoid unnecessary fillers or allergens. Established manufacturers with transparent quality control processes and certifications like USDA Organic, Non-GMO, or GMP earned higher ratings. Patented extracts backed by clinical research received additional recognition for consistency and safety data.

Complementary Ingredients & Synergy

Some supplements enhance olive leaf's benefits through thoughtful additions. We evaluated whether extra ingredients genuinely amplify results or just inflate the price. Smart combinations like Solaray's addition of lemon balm for stress-related blood pressure support earned points, while cluttered formulas that dilute key actives were penalized. The best synergistic formulas amplify specific benefits without compromising the primary olive compounds.

Value & User Experience

True value goes beyond price per bottle. We calculated cost per effective dose and considered practical factors like capsule size, dosing frequency, and how long a bottle lasts. Products that make supplementation easy and sustainable scored highest. This includes pleasant taste for liquids, reasonable capsule sizes, money-back guarantees, and responsive customer service. After all, the best supplement is one you'll actually take consistently.

Olive Leaf Extract Supplements Ranked (Comparison Table)

Below is our comprehensive comparison of the top 13 olive leaf extract supplements available today. We've evaluated each product across the five criteria discussed above.

Each category uses a simple rating system: 🟢 indicates excellent performance, 🟡 shows good or moderate results, and 🔴 highlights areas where products fall short. After extensive testing and analysis, Olivea's innovative formula earned our top recommendation for delivering unmatched cardiovascular benefits.

The comparison reveals why Olivea stands apart from traditional olive leaf extracts. While many supplements focus solely on oleuropein content, Olivea delivers the more potent hydroxytyrosol compound suspended in extra virgin olive oil for superior absorption. This table will help you understand exactly what you're getting with each option and why we believe Olivea offers the most comprehensive cardiovascular and antioxidant benefits available.

1. Olivea EVOO & Hydroxytyrosol Supplement

Olive Leaf Extract Content

Olivea represents a breakthrough in olive-based supplementation. Rather than traditional olive leaf extract, each capsule delivers 20 mg of pure hydroxytyrosol—the most potent polyphenol in olives—suspended in premium Greek extra virgin olive oil. This dose equals the polyphenols you'd get from drinking 100 tablespoons of top-quality olive oil daily, providing 4 times the minimum effective dose identified by European health authorities for protecting LDL cholesterol.

Notable Features

• Capsule-in-Capsule Technology: Inner capsule of hydroxytyrosol suspended within outer capsule of golden EVOO for optimal absorption 

• Physician-Developed: Created in collaboration with cardiologists specifically for cardiovascular support 

• Premium Sourcing: Early-harvest Kalamata olives from Messinia, Greece provide exceptional polyphenol content 

• Complete Support System: More than just a supplement—includes educational booklets, digital resources, and ongoing guidance about vascular health 

• Third-Party Tested: Every batch verified for purity and potency with no preservatives or fillers

About Olivea EVOO & Hydroxytyrosol Supplement

Olivea emerged from a simple question: how can we capture the heart-healthy benefits of the Mediterranean diet in a convenient daily capsule? The answer required innovation beyond traditional extraction methods. By combining concentrated hydroxytyrosol with organic extra virgin olive oil in their patented capsule-in-capsule design, Olivea mimics how these polyphenols naturally occur in food, dramatically improving absorption.

What sets Olivea apart extends beyond the capsule itself. Customers receive a comprehensive vascular health education system including science-backed booklets explaining cardiovascular wellness, email series with actionable health tips, and digital resources covering nutrition, exercise, and lifestyle factors that support heart health. This holistic approach transforms supplementation from a passive activity into an active journey toward better health.

Why We Chose Olivea EVOO & Hydroxytyrosol Supplement

Olivea earned our top ranking by revolutionizing olive supplementation. While competitors focus on oleuropein, Olivea delivers hydroxytyrosol—a smaller, more bioactive molecule with superior cardiovascular benefits. The capsule-in-capsule technology ensures maximum absorption, while the educational resources empower users to make comprehensive lifestyle improvements.

Pros & Cons of Olivea EVOO & Hydroxytyrosol Supplement

Who Is Olivea EVOO & Hydroxytyrosol Supplement For?

Olivea's EVOO & Hydroxytyrosol Supplement is designed for adults who take their cardiovascular health seriously and want the most advanced olive polyphenol supplement available. Here's who will benefit most:

• People with Cardiovascular Risk Factors. If you have elevated cholesterol, high blood pressure, or a family history of heart disease, Olivea's clinically-proven dose of hydroxytyrosol directly addresses these concerns. It's particularly valuable for those whose doctors have suggested dietary changes to improve heart health markers.

• Mediterranean Diet Enthusiasts. Perfect for those who understand the longevity benefits of olive oil consumption but struggle to incorporate 3-4 tablespoons of high-quality EVOO into their daily diet. Olivea captures these benefits in one convenient capsule.

• Active Adults and Athletes. The powerful antioxidant properties help combat exercise-induced oxidative stress and support faster recovery. Ideal for runners, cyclists, and fitness enthusiasts who want to protect their cardiovascular system during intense training.

• Professionals in High-Stress Careers. Chronic stress damages blood vessels and increases inflammation. Olivea's anti-inflammatory properties are particularly beneficial for executives, healthcare workers, and others in demanding roles who need cardiovascular protection.

• People Taking Statin Medications. Those on cholesterol-lowering drugs often seek complementary natural support. Olivea's hydroxytyrosol protects LDL cholesterol from oxidation—a benefit statins don't provide—making it an excellent addition to pharmaceutical treatment (with doctor approval).

• Individuals Focused on Brain Health. Emerging research links hydroxytyrosol to cognitive protection. If you're concerned about maintaining mental sharpness as you age or have a family history of cognitive decline, Olivea offers dual cardiovascular and neuroprotective benefits.

• Those Who've Tried Other Olive Leaf Supplements. If you've used traditional olive leaf extracts and want to upgrade to something more potent and bioavailable, Olivea represents the next generation of olive-based supplementation with superior absorption and stronger clinical evidence.

2. Gaia Herbs Olive Leaf 

Olive Leaf Extract Content

Gaia Herbs delivers 680 mg of olive leaf extract per capsule, standardized to 50 mg oleuropein.

Notable Features

• Farm-to-Capsule Quality: Grown on Gaia's certified organic farm in North Carolina

• Liquid Phyto-Caps®: Extract suspended in liquid form inside vegetarian capsules

• High Oleuropein: 50 mg per capsule exceeds many competitors

• Transparency Program: "Meet Your Herbs" traceability with testing results

Their olive leaf supplement reflects this commitment—grown on their certified organic farm, harvested at peak potency, and processed using proprietary extraction methods. The liquid phyto-cap technology sets them apart, delivering herbs in their most bioavailable form without tablets or powders.

Why We Chose Gaia Herbs Olive Leaf

Gaia earned high marks for combining potency with purity. The 50 mg oleuropein per capsule means effective dosing without handfuls of pills. Their organic certification, transparent testing, and decades of herbal expertise make this a trustworthy choice for traditional olive leaf benefits.

Pros & Cons of Gaia Herbs Olive Leaf

Who Is Gaia Herbs Olive Leaf For?

Gaia's olive leaf appeals to health-conscious individuals who value organic sourcing and traditional herbal medicine:

• Immune System Supporters: Those seeking natural defense during cold and flu season

• Organic Purists: Consumers who exclusively buy certified organic supplements

• Holistic Health Practitioners: Often recommended by naturopaths and herbalists 

• Sensitive Individuals: Perfect for those avoiding fillers and synthetic additives

Gaia Herbs vs. Olivea

While Gaia offers excellent organic olive leaf extract, Olivea surpasses it in several key areas. Gaia provides 50 mg oleuropein per capsule, but Olivea delivers 20 mg of the more potent hydroxytyrosol—a compound with superior cardiovascular benefits. Olivea's capsule-in-capsule technology with EVOO ensures optimal absorption, while Gaia's liquid caps, though good, lack this advanced delivery system. Additionally, Olivea includes comprehensive educational resources about vascular health, transforming supplementation into a complete wellness journey. For those seeking maximum cardiovascular protection and innovation, Olivea clearly outperforms traditional olive leaf extracts like Gaia's.

3. Solgar Olive Leaf Extract

Olive Leaf Extract Content

Solgar combines 225 mg of standardized olive leaf extract (6% oleuropein, yielding 13.5 mg) with 225 mg of olive leaf powder per capsule. This dual approach provides both concentrated oleuropein and the full spectrum of olive leaf compounds. The recommended dose of 1-3 capsules daily can deliver up to 40 mg oleuropein.

Notable Features

• Dual Formula: Standardized extract plus whole leaf powder 

• PhytO2X® System: Antioxidant blend with vitamin C and beta-carotene 

• Heritage Brand: Over 75 years of supplement manufacturing

By including both standardized extract and whole leaf powder, they honor the belief that nature's full spectrum of compounds work synergistically. The addition of PhytO2X®—their proprietary antioxidant blend—helps preserve freshness while providing additional immune support.

Why We Chose Solgar Olive Leaf Extract

Solgar made our list for its trusted brand legacy and balanced formulation approach. While the oleuropein content per capsule is modest, the flexibility to adjust dosing and the inclusion of whole herb powder appeals to those who believe in holistic supplementation. Their rigorous quality standards and wide availability make this a reliable mainstream choice.

Pros & Cons of Solgar Olive Leaf Extract

Who Is Solgar Olive Leaf Extract For?

Solgar's olive leaf suits those who value established brands and gentle supplementation:

• Supplement Beginners: Lower dose per capsule allows gradual introduction to olive leaf  

• Brand Loyalists: Those who trust Solgar's decades of quality and consistency

• Flexible Dosing Needs: Perfect for adjusting intake based on wellness goals 

• Whole Food Advocates: Appeals to those wanting both extract and whole herb benefits

Solgar vs. Olivea

While Solgar represents quality traditional supplementation, Olivea operates in an entirely different league. Solgar's 13.5 mg oleuropein per capsule pales compared to Olivea's 20 mg hydroxytyrosol—a more bioactive compound. Where Solgar requires three capsules for meaningful benefits, Olivea delivers superior results in one. Solgar's conventional approach, while time-tested, lacks Olivea's innovative capsule-in-capsule technology that ensures maximum absorption. Most significantly, Olivea provides a complete cardiovascular wellness system with educational resources, while Solgar offers just a basic supplement. For serious heart health support, Olivea's advanced formulation and comprehensive approach make it the clear superior choice.

4. Pure Encapsulations Olive Leaf Extract

Olive Leaf Extract Content

Pure Encapsulations delivers 500 mg of olive leaf extract standardized to 15% oleuropein, providing 75 mg per capsule. This represents one of the higher single-capsule oleuropein doses available.

Manufactured in their Sudbury, Massachusetts facility, every batch undergoes independent laboratory testing for contaminants and potency verification. This meticulous approach has made them the go-to brand for integrative medicine practitioners.

Why We Chose Pure Encapsulations Olive Leaf Extract

Pure Encapsulations earned its spot through exceptional purity and potency. The 75 mg oleuropein per capsule ranks among the highest available, while the hypoallergenic formula ensures virtually anyone can take it safely. Their professional-grade manufacturing and transparent testing protocols provide confidence in consistent quality.

Pros & Cons of Pure Encapsulations Olive Leaf Extract

Who Is Pure Encapsulations Olive Leaf Extract For?

Pure Encapsulations appeals to those requiring the cleanest possible supplementation:

• Allergy and Sensitivity Sufferers: Ideal for those with multiple food allergies or chemical sensitivities

• Healthcare-Recommended Users: Perfect when prescribed by naturopaths or integrative doctors 

• Therapeutic Dose Seekers: Those needing higher oleuropein levels for specific health conditions

• Long-Term Supplement Users: The pure formula minimizes exposure to unnecessary additives over time

Pure Encapsulations vs. Olivea

Pure Encapsulations offers exceptional purity, but Olivea provides superior overall benefits. While Pure delivers 75 mg oleuropein, Olivea's 20 mg hydroxytyrosol has greater antioxidant potency and direct cardiovascular benefits. Pure Encapsulations uses a standard capsule, whereas Olivea's innovative capsule-in-capsule design with EVOO dramatically enhances absorption. Additionally, Olivea addresses heart health comprehensively through both its formula and educational resources, while Pure offers just the supplement. For those prioritizing maximum cardiovascular protection and bioavailability over hypoallergenic considerations, Olivea's advanced delivery system and complete wellness approach make it the optimal choice.

5. NOW Foods Olive Leaf Extract

Olive Leaf Extract Content

NOW Foods provides 500 mg of olive leaf extract standardized to 6% oleuropein, yielding 30 mg per capsule. The suggested use of 1-3 capsules daily allows flexible dosing up to 90 mg oleuropein. With 100-120 capsules per bottle, this budget-friendly option can last 1-4 months depending on usage.

Notable Features

• Budget-Friendly: One of the most affordable reputable options 

• GMP Certified: Manufactured in NOW's own facilities 

• Non-GMO: Verified through testing programs

Manufactured in their Illinois facilities with extensive in-house testing, NOW ensures that budget-conscious doesn't mean compromising on quality. They test raw materials and finished products for identity, purity, and potency.

Why We Chose NOW Foods Olive Leaf Extract

NOW Foods earned inclusion as our best value pick. While the per-capsule potency is moderate, the ability to take multiple capsules still costs less than premium brands. Their GMP certification, transparent testing, and 50+ year reputation prove that affordable can still mean effective.

Pros & Cons of NOW Foods Olive Leaf Extract

Who Is NOW Foods Olive Leaf Extract For?

NOW's olive leaf serves budget-conscious consumers seeking reliable benefits:

• First-Time Users: Affordable entry point to try olive leaf supplementation 

• Fixed-Income Individuals: Retirees and students needing quality on a budget

• Maintenance Dosing: Those wanting modest daily support without high costs

• Bulk Buyers: Families or individuals who prefer stocking up on basics

NOW Foods vs. Olivea

While NOW Foods offers solid value, Olivea delivers dramatically superior benefits. NOW's 30 mg oleuropein per capsule would require three capsules to approach the potency of Olivea's single capsule—and even then, oleuropein can't match hydroxytyrosol's cardiovascular effects. NOW uses standard encapsulation, while Olivea's capsule-in-capsule technology ensures optimal absorption. Most importantly, NOW provides just a basic supplement, whereas Olivea includes comprehensive cardiovascular education and support. For those who can invest in their health, Olivea's advanced formulation and complete wellness system justify the higher price through measurably better results.

The company sources from Mediterranean regions where olives naturally develop high polyphenol content.

Why We Chose Nature's Way Olive Leaf

Nature's Way impressed us with its combination of high standardization, third-party certifications, and reasonable pricing. The 20% oleuropein extract delivers potent benefits in small, easy-to-swallow capsules. Their TRU-ID authentication provides extra confidence in an industry sometimes plagued by adulteration.

• Blood Pressure Support: Those using olive leaf specifically for cardiovascular health

• Twice-Daily Supplement Users: Already taking other supplements on similar schedule

Nature's Way vs. Olivea

Nature's Way offers respectable potency, but Olivea provides superior cardiovascular benefits. While Nature's Way delivers 50 mg oleuropein per capsule, this requires twice-daily dosing to achieve 100 mg. Olivea's single daily capsule contains 20 mg hydroxytyrosol—a more potent compound that directly protects LDL cholesterol. Nature's Way uses conventional encapsulation, whereas Olivea's oil-suspended delivery dramatically improves absorption. Furthermore, Olivea includes educational resources transforming supplementation into a complete wellness journey. For comprehensive heart health support in convenient once-daily dosing, Olivea's innovative formulation clearly surpasses traditional extracts like Nature's Way.

Why We Chose Oregon's Wild Harvest Olive Leaf

• Environmental Advocates: Support sustainable, family-owned businesses

Oregon's Wild Harvest vs. Olivea

Oregon's Wild Harvest offers exceptional organic purity, but Olivea delivers superior therapeutic benefits. While Oregon provides 40 mg organic oleuropein, Olivea's 20 mg hydroxytyrosol has greater cardiovascular impact according to research. Oregon uses traditional capsules, whereas Olivea's innovative oil-suspension technology ensures maximum absorption. Most significantly, Olivea provides comprehensive heart health education alongside supplementation, while Oregon offers just the product. For those seeking measurable cardiovascular improvements rather than just organic certification, Olivea's advanced formulation and complete wellness approach make it the clear winner.

• Combination Seekers: Prefer multi-benefit formulas over single ingredients 

• Evening Supplement Users: Lemon balm's calming effects complement nighttime dosing

Solaray vs. Olivea

While Solaray offers an interesting combination, Olivea provides more powerful cardiovascular protection. Solaray's 55 mg oleuropein with lemon balm addresses stress, but Olivea's 20 mg hydroxytyrosol directly protects arterial health at the cellular level. Solaray requires understanding herb interactions, while Olivea's pure olive-based formula works universally.

• Data-Driven Consumers: Appreciate clinical studies behind their supplements

Life Extension vs. Olivea

Life Extension offers impressive blood pressure support, but Olivea provides broader cardiovascular benefits. While Life Extension delivers 80 mg oleuropein plus celery, it requires twice-daily dosing and focuses primarily on blood pressure. Olivea's single daily capsule with 20 mg hydroxytyrosol protects against LDL oxidation, supports arterial health, and provides anti-inflammatory benefits beyond just blood pressure. Life Extension's standard capsules can't match Olivea's innovative oil-suspension delivery for absorption. Additionally, Olivea's comprehensive educational resources empower users to improve overall vascular health through lifestyle changes. For complete cardiovascular wellness rather than targeted blood pressure support, Olivea's advanced formulation and holistic approach make it the superior choice.

DFH uses standard encapsulation that can't compete with Olivea's innovative oil-suspension technology for bioavailability. Most significantly, Olivea includes comprehensive educational resources about heart health, while DFH provides just the supplement. For complete cardiovascular protection with optimal absorption and lifestyle support, Olivea's advanced delivery system and wellness approach clearly outperform even clinical-grade oleuropein products.

Healths Harmony vs. Olivea

Healths Harmony impresses with raw oleuropein content, but Olivea delivers superior cardiovascular benefits through innovation. While Healths Harmony's 150 mg oleuropein seems substantial, Olivea's 20 mg hydroxytyrosol provides more potent antioxidant protection according to research. Healths Harmony uses standard capsules that can't match Olivea's oil-suspension technology for absorption—meaning much of that 150 mg may not reach your bloodstream. Additionally, Olivea includes educational resources transforming supplementation into a complete wellness journey. For genuine cardiovascular protection rather than just high numbers on a label, Olivea's bioavailable formula and comprehensive approach make it the clear winner.

About NusaPure Olive Leaf Extract

NusaPure specializes in ultra-concentrated herbal extracts for those seeking maximum potency.

By adding BioPerine® (black pepper extract), they address the absorption challenges of such concentrated extracts. This family-owned company emphasizes small-batch production and rigorous testing to ensure their extreme potency claims are accurate.

Why We Chose NusaPure Olive Leaf Extract

NusaPure earned recognition for pushing the boundaries of olive leaf concentration. The 375 mg oleuropein per capsule appeals to those who believe maximum dosing yields maximum benefits. The addition of BioPerine® shows thoughtful formulation beyond just high numbers, addressing the bioavailability concerns of ultra-concentrated extracts.

Pros & Cons of NusaPure Olive Leaf Extract

Who Is NusaPure Olive Leaf Extract For?

This ultra-strength formula suits specific high-dose applications:

• Maximum Dose Believers: Think higher doses equal better results 

• Acute Support Needs: Fighting active infections or health challenges 

• Experienced Users: Have taken olive leaf before without adverse effects 

• Cost-Per-Milligram Shoppers: Want the most oleuropein for their money

NusaPure vs. Olivea

NusaPure offers extreme oleuropein content, but Olivea provides smarter cardiovascular support. While NusaPure's 375 mg oleuropein seems impressive, such high doses may exceed what the body can effectively use. Olivea's 20 mg hydroxytyrosol is precisely dosed based on clinical research and has superior bioactivity. Even with BioPerine®, NusaPure's standard capsule can't match Olivea's innovative oil-suspension delivery. Most importantly, Olivea includes educational resources helping users understand optimal dosing and lifestyle factors. For evidence-based cardiovascular protection rather than extreme dosing, Olivea's balanced approach and advanced delivery system make it the wiser choice.

• Potency Maximizers: Want the highest standardization possible 

• Data-Driven Users: Appreciate lab-verified potency claims

Toniiq vs. Olivea

While Toniiq impresses with extraction technology, Olivea provides superior real-world benefits. Toniiq's 250 mg oleuropein represents technical achievement, but Olivea's 20 mg hydroxytyrosol has greater cardiovascular impact according to research. Toniiq's standard capsule, despite high concentration, cannot match Olivea's oil-suspension delivery for actual absorption into the bloodstream. Furthermore, Olivea includes comprehensive educational resources about heart health, while Toniiq focuses solely on potency numbers. For meaningful cardiovascular protection with optimal bioavailability and lifestyle support, Olivea's complete wellness system clearly outperforms even the most concentrated traditional extracts.

What Is the Best Olive Leaf Extract Supplement?

After thoroughly evaluating 13 top olive leaf extract supplements, Olivea EVOO & Hydroxytyrosol Supplement stands alone as the clear winner. While every product on our list has merit, only Olivea delivers the complete package for cardiovascular health and longevity.

Why Olivea Is the Best Choice

• Olivea delivers 20 mg of pure hydroxytyrosol—the most potent olive polyphenol—providing 4x the clinically effective dose for protecting LDL cholesterol from oxidation.

• The patented capsule-in-capsule technology suspends hydroxytyrosol in extra virgin olive oil, mimicking nature's delivery system for maximum absorption that dry powders can't match.

• Beyond supplementation, Olivea includes educational booklets, email guidance, and digital resources that transform pill-taking into a comprehensive cardiovascular wellness journey.

• Every capsule contains physician-developed, third-party tested ingredients from premium early-harvest Greek olives with zero fillers or artificial additives.

• While competitors require multiple capsules or twice-daily dosing, Olivea provides complete cardiovascular support in just one small, easy-to-swallow daily capsule.

Why Standard OLE Supplements Aren't Enough

Traditional olive leaf extracts focus on oleuropein, which must convert to hydroxytyrosol in your body—an inefficient process. Even "high-potency" products with 100-300 mg oleuropein can't match the cardiovascular benefits of Olivea's 20 mg pure hydroxytyrosol.

Standard capsules also limit absorption. Whether it's organic, hypoallergenic, or ultra-concentrated, a dry powder in a regular capsule simply can't compete with Olivea's oil-suspension technology for bioavailability.

Most importantly, other supplements are just pills in a bottle. Olivea provides a complete cardiovascular wellness system with the education and support needed to maximize your results.

Take Action for Your Heart Health

Don't settle for outdated olive leaf extracts when you can experience the next generation of cardiovascular supplementation. Olivea's innovative formula, superior absorption, and comprehensive support system make it the smartest investment in your heart health.
