7 Best Hydroxytyrosol Supplements for Longevity (2026)
Type "hydroxytyrosol" into a supplement search bar and you get olive leaf extracts that never name a milligram, beauty drinks with unlisted doses, and a handful of capsules that actually put a number on the label. This roundup covers that handful. Seven products, ranked by the only three things that matter for this compound: how many milligrams of hydroxytyrosol a capsule actually carries, whether that figure comes from a lab report you can read, and whether the source is olive fruit, olive leaf, or an extract standardized to something else entirely.
Two things to know before the list. First, the reference dose is small. The EU-recognized health claim for olive polyphenols is built on 5 mg of hydroxytyrosol and its derivatives a day, which is why a 20 to 25 mg capsule clears it several times over; our EFSA claim breakdown explains the threshold. Second, "for longevity" in the title means what the aging research measures, which is oxidative-stress and inflammation biomarkers, not lifespan. We are careful about that distinction below, because the supplement aisle is not.
One of the seven is ours, and it sits at number one for two reasons that matter more than the number printed on a label. It is the only product on the list where the hydroxytyrosol figure is lab-verified per batch and published, and it is the only one that delivers the compound inside extra virgin olive oil, the carrier a randomized trial found recovers more hydroxytyrosol than any other. Two products print a higher number on the label; neither publishes a report, and neither delivers it in oil.
The seven, in ranked order:
- Olivea Hydroxytyrosol Supplement: Best Overall. Lab-verified 23.5 mg per capsule, fruit-derived, delivered inside high-phenolic extra virgin olive oil.
- ProHealth Longevity Hydroxytyrosol Extreme: Best Pure-Dose Capsule. 25 mg per capsule from organic olive leaf, 90 capsules.
- Swanson Olea25 Olive Leaf Extract: Best Value Standardized Capsule. 100 mg olive leaf extract standardized to 25 percent hydroxytyrosol, 25 mg per capsule.
- MCS Formulas Hydroxytyrosol: Highest Labeled Dose. 50 mg per capsule, shipped from Europe.
- Island Nutrition 20 Percent Hydroxytyrosol Complex: Best Fruit-Extract Alternative. 100 mg Spanish olive fruit extract, about 20 mg hydroxytyrosol.
- Designs for Health Olive Leaf Extract: Best Olive Leaf Complex. Standardized to about 100 mg oleuropein; hydroxytyrosol present but unquantified.
- Pure Encapsulations Olive Leaf Extract: Best Hypoallergenic Option. About 75 mg oleuropein; not a hydroxytyrosol product, included because people search for it as one.
How We Rate Hydroxytyrosol Supplements
Five criteria, weighted toward the verified number, the proof behind it, and whether the carrier lets the compound be absorbed.
1. Labeled Hydroxytyrosol Dose
The label has to state hydroxytyrosol in milligrams, or a standardization percentage that lets you calculate it. "Olive extract, 500 mg" tells you nothing. We rated every product against the 5 mg daily figure behind the EU claim and the 5 to 20 mg range the human trials actually used, which our hydroxytyrosol dosage guide lays out.
2. Verification
A "lab tested" badge is decoration. A batch certificate of analysis you can open is proof. Products that publish one scored highest; products that state a number without a report scored in the middle; products with no hydroxytyrosol number at all scored lowest on this criterion regardless of how good the rest of the label looked.
3. Source
Hydroxytyrosol in the Mediterranean-diet research comes from olive fruit and oil. Most capsules on the market are olive leaf extracts converted toward hydroxytyrosol, or olive leaf standardized to oleuropein, which is a related but different compound. We favored fruit-derived products and, where the source is leaf, products that still put a hydroxytyrosol milligram on the label.
4. Format and Delivery
Hydroxytyrosol is a small polar molecule, and how it is carried decides how much of it you absorb. A 20-person randomized trial gave the same 5 mg dose in six different carriers. Extra virgin olive oil produced the highest plasma peak at 30 minutes and the highest 24-hour urinary recovery: 37 percent more than refined olive oil, 56 percent more than flax oil, 2.6 times grapeseed oil, and the water and yogurt arms showed no significant rise at all. A milligram that is not absorbed is not a dose. That is why the carrier weighs as much as the number in our ranking.
5. Value per Milligram
Price divided by total verified hydroxytyrosol in the bottle. A more expensive bottle with a published number routinely beats a cheaper bottle with none.
Hydroxytyrosol Supplements Compared
Doses are as labeled by each producer. Prices and counts for non-Olivea products are from publicly available sources at the time of writing and should be checked before purchase.
| Product | Hydroxytyrosol per capsule | Source | Count and price | Lab report | Best for |
| Olivea Hydroxytyrosol Supplement | 23.5 mg, lab-verified | Olive fruit extract in extra virgin olive oil | $40 one-time, $28 to $32 on subscription | Published per batch | Verified dose, delivered in EVOO |
| ProHealth Longevity Hydroxytyrosol Extreme | 25 mg, as labeled | Organic olive leaf | 90 capsules, about $37 | Not published | Labeled 25 mg, no report, dry capsule |
| Swanson Olea25 Olive Leaf Extract | 25 mg, as labeled (100 mg at 25 percent) | Olive leaf | 60 capsules | Not published | Value standardized capsule |
| MCS Formulas Hydroxytyrosol | 50 mg, as labeled | Spanish olive trees | Sold from Europe, international shipping | Not published | Labeled 50 mg, above the trial range, dry capsule |
| Island Nutrition 20 Percent Hydroxytyrosol Complex | About 20 mg (100 mg at 20 percent) | Spanish olive fruit extract | Amazon | Not published | Fruit-derived dry capsule |
| Designs for Health Olive Leaf Extract | Not stated (about 100 mg oleuropein) | Olive leaf | Practitioner channels | Not published | Olive leaf complex |
| Pure Encapsulations Olive Leaf Extract | Not stated (about 75 mg oleuropein) | Olive leaf | Retail and online | Not published | Hypoallergenic olive leaf |
Read the second and fifth columns together. Only one product pairs a hydroxytyrosol number with a published report, and it is also the only one delivered in olive oil. Two products print a higher number on the label than our verified 23.5 mg; neither backs it with a report, and both are dry capsules. Two products do not state a hydroxytyrosol figure at all and are here because searchers keep landing on them looking for one.
Absorption: Why the Number on the Label Is Not the Point
Most comparisons of hydroxytyrosol supplements stop at milligrams. The research does not. In the trial above, every arm received exactly 5 mg of hydroxytyrosol, the figure behind the EU health claim, and the only variable was what carried it. Extra virgin olive oil recovered 0.86 micrograms per milligram of creatinine in 24-hour urine. Refined olive oil recovered 0.63, flax oil 0.55, grapeseed oil 0.33, and the yogurt and water arms produced no significant increase over baseline. Same molecule, same dose, up to 2.6 times the recovery depending on the carrier, and in the non-fat arms almost none.
The trial did not test an Olivea product. It tested the design decision behind it. A dry powder capsule dissolving in the stomach is closer to the water arm of that trial than to the oil arm; that is an inference from the trial rather than something it measured, and it is the reason we built the capsule with the extract sealed inside extra virgin olive oil instead of pressed into a powder. Olive phenols are already among the best-absorbed dietary phenols when they arrive in oil, and the carrier is how you keep that advantage in a capsule. Read the labeled doses on this page with that in mind: 25 mg or 50 mg in a dry capsule is a bigger number, not a proven bigger dose.
1. Olivea Hydroxytyrosol Supplement: Best Overall
Dose and Source
Each capsule carries a lab-verified 23.5 mg of hydroxytyrosol, more than four times the 5 mg behind the EU health claim. The compound comes from olive fruit extract, 200 mg of it, sealed inside a 400 mg core of high-phenolic extra virgin olive oil in a capsule-in-capsule design. The oil is not a filler. It is the carrier that recovered 2.6 times more hydroxytyrosol than grapeseed oil and 37 percent more than refined olive oil at the same dose in the trial above, and the reason we chose the format.
Notable Features
- Published lab results: the hydroxytyrosol figure is verified per batch and posted on our lab results page.
- Fruit-derived: olive extract, not olive leaf standardized to oleuropein.
- Oil delivery: the extract sits inside high-phenolic EVOO rather than a dry powder.
- Medical advisory board: a board of Harvard-trained cardiologists sets Olivea's polyphenol thresholds.
- One capsule a day: $40 one-time, or $32, $30 and $28 a month on monthly, quarterly and six-month subscriptions.
About Olivea Hydroxytyrosol Supplement
Olivea built the capsule for people who used to take a morning olive oil shot and wanted the hydroxytyrosol without the calories or the taste. The design question was how to keep the compound in oil, since a plain powder capsule leaves the matrix behind. The answer was to put the extract inside the oil rather than beside it. Every batch is tested, and the number is published rather than claimed, which is the standard we hold every other product on this page to.
Pros and Cons
| Pros | Cons |
| Lab-verified 23.5 mg hydroxytyrosol per capsule, results published | Two products print a higher number on the label, without a report or an oil carrier |
| Fruit-derived hydroxytyrosol delivered in extra virgin olive oil | Premium price at $40 one-time |
| Subscription pricing down to $28 a month | Sold direct; not in mass-market retail |
| Single daily capsule | Small batches can sell out between harvests |
Who It Is For
Anyone who wants a hydroxytyrosol number they can check, and who prefers the compound in the oil it comes from. It is the natural next step for people who take olive oil shots and want the dose without the ritual. If you would rather get hydroxytyrosol from food, our polyphenol-rich olive oil roundup covers the oils that publish their numbers.
2. ProHealth Longevity Hydroxytyrosol Extreme: Best Pure-Dose Capsule
Dose and Source
ProHealth labels 25 mg of hydroxytyrosol per capsule, derived from organic olive leaf, in a 90-capsule bottle sold on its own site and through retailers for about $37. On the labeled number it is slightly above our verified 23.5 mg, and it is the most widely stocked dedicated hydroxytyrosol product in the United States. As a dry leaf-extract capsule it does not carry the oil matrix that drove absorption in the trial.
Notable Features
- 25 mg labeled dose: among the highest available from a US brand.
- Organic olive leaf source: standardized extract rather than fruit.
- 90 capsules: a three-month supply at one a day.
- Wide availability: brand site, iHerb and Amazon.
About ProHealth Longevity Hydroxytyrosol Extreme
ProHealth is a longevity-focused supplement brand, and this is its dedicated hydroxytyrosol capsule. If you search "hydroxytyrosol" on the major online vitamin retailers, it is essentially the one standalone product you will find, surrounded by olive leaf extracts standardized to oleuropein instead. That reach is its strength. The gap is verification: the dose is stated on the label, but we did not find a batch certificate of analysis published for the product.
Pros and Cons
| Pros | Cons |
| 25 mg labeled hydroxytyrosol per capsule | No published batch lab report |
| Three-month supply for about $37 | Leaf-derived, delivered as a dry capsule |
| Easiest dedicated product to find in the US | Marketplace listings vary in who ships them |
Who It Is For
Buyers who want the highest labeled dose from a US brand at a low cost per milligram, and who are comfortable taking the label's word for it. If you buy it on Amazon, use the "ships from and sold by" filter and prefer the brand or Amazon as the seller.
3. Swanson Olea25 Olive Leaf Extract: Best Value Standardized Capsule
Dose and Source
Each 100 mg olive leaf capsule is standardized to 25 percent hydroxytyrosol, which works out to 25 mg per capsule, in a 60-capsule bottle sold through swansonvitamins.com. The standardization is the important part: most olive leaf products are standardized to oleuropein, and this one is standardized to hydroxytyrosol itself.
Notable Features
- 25 percent hydroxytyrosol standardization: rare for an olive leaf product.
- 25 mg per capsule: level with ProHealth on the labeled number.
- Legacy brand: Swanson has sold supplements direct for decades.
- 60 capsules: a two-month supply at one a day.
About Swanson Olea25
Olea25 sits in Swanson's Superior Herbs line and is the value entry among the standardized capsules here. It does the one thing that matters on the label, naming hydroxytyrosol rather than hiding behind "olive extract," and it does it at a legacy-brand price. Like ProHealth, it is leaf-derived and does not publish a batch report.
Pros and Cons
| Pros | Cons |
| Standardized to hydroxytyrosol, not oleuropein | No published batch lab report |
| 25 mg per capsule | Smaller 60-count bottle |
| Established direct-sale brand | Leaf-derived dry capsule |
Who It Is For
Price-conscious buyers who still insist on a hydroxytyrosol milligram on the label. It is the sensible pick if ProHealth is out of stock.
4. MCS Formulas Hydroxytyrosol: Highest Labeled Dose
Dose and Source
MCS Formulas labels 50 mg of hydroxytyrosol per capsule, sourced from Spanish olive trees, and sells from Europe with international shipping. That is double the dose of anything else on this list and well above the range the human trials used, which is worth pausing on rather than treating as a bonus.
Notable Features
- 50 mg labeled dose: the highest here.
- Spanish olive source.
- European brand: international shipping to the US.
About MCS Formulas Hydroxytyrosol
MCS Formulas is a European supplement maker with a following among people who read the research closely. The 50 mg figure is the reason it is on this list. The trade-offs are practical: shipping from Europe, no US retail presence, and no published batch report we could find. On dose, remember that the trials with the best evidence used 5 to 20 mg a day, and the EU's 2017 safety opinion on hydroxytyrosol as a novel food set intake levels well below what a 50 mg daily capsule provides. More is not obviously better; a higher dose is a reason to check with a clinician, not a reason to skip the check.
Pros and Cons
| Pros | Cons |
| 50 mg labeled hydroxytyrosol per capsule | Dose is above the trial range and the EFSA novel-food intake levels |
| Named olive source | Ships from Europe; no US retail |
| Clear milligram labeling | No published batch lab report |
Who It Is For
Experienced supplement users who specifically want a high single-capsule dose and have discussed it with their doctor. Not the place to start.
5. Island Nutrition 20 Percent Hydroxytyrosol Complex: Best Fruit-Extract Alternative
Dose and Source
Island Nutrition sells 100 mg capsules of Spanish olive fruit extract standardized to 20 percent hydroxytyrosol, about 20 mg per capsule, primarily through Amazon. It is the only product on this list other than ours that is fruit-derived, which matters if you want the compound as the research studied it.
Notable Features
- Olive fruit extract: not leaf.
- About 20 mg per capsule: four times the EU claim threshold.
- Amazon availability: fast shipping, easy returns.
About Island Nutrition Hydroxytyrosol Complex
This is a straightforward fruit-extract capsule with a clear standardization on the label. Its weakness is the channel: Amazon is the widest hydroxytyrosol marketplace and also the riskiest, because listings may be fulfilled by resellers and polyphenols degrade in warehouse heat. We did not find a published batch report. If you buy it, buy from the brand or Amazon as the seller, not a third party.
Pros and Cons
| Pros | Cons |
| Fruit-derived hydroxytyrosol | No published batch lab report |
| Clear 20 percent standardization | Marketplace channel with variable sellers |
| Fast Amazon shipping | Dry capsule, no oil matrix |
Who It Is For
Buyers who want fruit-derived hydroxytyrosol at a lower price than ours and are willing to do the seller check on Amazon themselves.
6. Designs for Health Olive Leaf Extract: Best Olive Leaf Complex
Dose and Source
Each capsule carries 500 mg of olive leaf extract standardized to 20 percent oleuropein, about 100 mg, and the extract contains other olive phenols including hydroxytyrosol, though the label does not quantify the hydroxytyrosol. That makes it a strong olive leaf product and a weak hydroxytyrosol product, and it is important to know which one you are buying.
Notable Features
- About 100 mg oleuropein per capsule: a high standardization for olive leaf.
- Practitioner-grade brand: widely used through clinician channels.
- Whole olive leaf phenol profile: hydroxytyrosol present but unstated.
About Designs for Health Olive Leaf Extract
Designs for Health is a practitioner brand, and this is one of the more potent oleuropein-standardized olive leaf extracts on the market. Oleuropein is the compound olive leaf is known for; the body converts some of it toward hydroxytyrosol, but how much reaches you from a leaf extract is not something the label can tell you. Our olive leaf extract roundup ranks it against its actual peers. It typically involves twice-daily dosing.
Pros and Cons
| Pros | Cons |
| High oleuropein standardization | No hydroxytyrosol milligram on the label |
| Trusted practitioner brand | Twice-daily dosing |
| Full olive leaf phenol profile | Not a hydroxytyrosol supplement in the strict sense |
Who It Is For
People who want the olive leaf complex specifically, or whose practitioner recommended it. If you want a hydroxytyrosol number, look higher up this list.
7. Pure Encapsulations Olive Leaf Extract: Best Hypoallergenic Option
Dose and Source
Pure Encapsulations offers 500 mg of olive leaf extract standardized to 15 percent oleuropein, about 75 mg per capsule, in a hypoallergenic formula without fillers or common allergens. It does not state a hydroxytyrosol content. We include it because a large share of searches for "Pure Encapsulations hydroxytyrosol" land on this page, and the honest answer is that Pure Encapsulations does not make a standalone hydroxytyrosol capsule; this olive leaf product is the closest thing in its catalog.
Notable Features
- About 75 mg oleuropein per capsule.
- Hypoallergenic: no fillers or common allergens.
- Widely stocked: practitioner and retail channels.
About Pure Encapsulations Olive Leaf Extract
Pure Encapsulations is known for clean, allergen-free formulations, and this product fits that reputation. As an olive leaf extract it is solid and moderately potent. As a hydroxytyrosol source it is unquantified, so it belongs at the bottom of a hydroxytyrosol ranking even though it might sit near the top of an olive leaf one.
Pros and Cons
| Pros | Cons |
| Hypoallergenic, filler-free formulation | No hydroxytyrosol milligram on the label |
| Reliable, widely available brand | Moderate oleuropein dose |
| Good choice for sensitive users | Not a hydroxytyrosol supplement |
Who It Is For
People with allergies or sensitivities who want an olive leaf extract from a brand they already trust. Not for anyone shopping specifically for hydroxytyrosol.
Leaf-Derived vs Fruit-Derived Hydroxytyrosol
Most capsules on the market start from olive leaf, because leaf is cheap and rich in oleuropein, which can be processed toward hydroxytyrosol. The research on olive polyphenols, from the EUROLIVE trial onward, used olive oil, which means fruit-derived hydroxytyrosol in a fat matrix. The bioavailability trial found the same dose recovered 2.6 times higher from extra virgin olive oil than from grapeseed oil, with no significant rise from water or yogurt. That is not proof that dry leaf-derived capsules do nothing; it is the reason the carrier and the source are two of our five criteria rather than footnotes, and why a bigger number on a dry capsule does not automatically mean more hydroxytyrosol in you. Our hydroxytyrosol guide covers the chemistry in more depth.
What "For Longevity" Actually Means Here
The phrase in the title needs a plain definition. The strongest human evidence on hydroxytyrosol comes from a 16-week randomized trial in which 15 mg a day moved a set of oxidative-stress and inflammation biomarkers, the kind of markers aging research tracks; our breakdown of that trial lists which ones changed and which did not. No supplement on this list has been shown to extend lifespan, and none should be sold as if it has. What the evidence supports is narrower and still worth having: a well-characterized olive polyphenol, at a modest daily dose, with a recognized effect on blood-lipid oxidation and a growing trial record on inflammation markers.
Frequently Asked Questions About Hydroxytyrosol Supplements
How much hydroxytyrosol should I take per day?
The EU health claim is built on 5 mg of hydroxytyrosol and its derivatives a day. Human trials have commonly used 5 to 20 mg, with a 16-week study at 15 mg a day providing some of the clearest biomarker results. A 20 to 25 mg capsule covers that range in one dose. Higher labeled doses, such as 50 mg, sit above the trial range and are a reason to talk to your doctor first.
Is hydroxytyrosol safe?
The European Food Safety Authority reviewed hydroxytyrosol as a novel food in 2017 and found it safe at the intake levels it assessed; our summary of that opinion covers the details. It is a compound people have consumed in olive oil for thousands of years. As with any supplement, anyone pregnant, on medication, or managing a condition should check with a clinician before starting.
Can I just get hydroxytyrosol from olive oil instead?
Yes, if the oil carries enough. The EU claim requires 5 mg of hydroxytyrosol and derivatives per 20 g of oil, roughly 250 mg/kg in total polyphenols, and most supermarket extra virgin tests below that. A high-phenolic oil at 1,000+ mg/kg clears it in a tablespoon. Our olive oil capsule roundup and healthiest olive oils guide cover both routes.
Does Pure Encapsulations make a hydroxytyrosol supplement?
Not a standalone one. Pure Encapsulations sells an olive leaf extract standardized to about 75 mg oleuropein per capsule, with no hydroxytyrosol figure on the label. If you want a stated hydroxytyrosol dose, ProHealth, Swanson Olea25 and our own capsule all put one on the bottle.
Does hydroxytyrosol help with weight loss?
There is no good human evidence that it does, and we do not sell it for that. The trial record is about blood-lipid oxidation and inflammation biomarkers. A supplement marketed for hydroxytyrosol weight loss is making a claim the research does not support.
Does a higher labeled dose mean more hydroxytyrosol absorbed?
Not on its own. In the 20-person trial that varied only the carrier, the same 5 mg recovered 2.6 times higher from extra virgin olive oil than from grapeseed oil, and water and yogurt produced no significant rise at all. A 50 mg dry capsule and a 23.5 mg capsule delivered in olive oil are not comparable on the label number alone, and only the second has a published report behind it.
Final Verdict
Seven products, and the honest split is simple. Five put a hydroxytyrosol number on the label. One of those five publishes a lab report to back it, and it is the only one delivered in olive oil, the carrier the absorption trial favored. Two print a higher number on the label than our verified 23.5 mg, without a report and without the oil. Two are olive leaf products that people find while searching for hydroxytyrosol and that do not state a hydroxytyrosol content at all.
The Olivea Hydroxytyrosol Supplement is the pick: the highest verified dose on this list at 23.5 mg, delivered in the carrier the absorption trial favored, with the number on our lab results page. ProHealth is the runner-up if you want a labeled 25 mg from a US brand at a lower cost per milligram and are comfortable without a report or the oil. If you want the same on a budget, Swanson Olea25. If you want fruit-derived at a lower price and will vet the seller, Island Nutrition. And if you would rather get your hydroxytyrosol from a tablespoon of oil, start with the oils that publish their numbers in our polyphenol-rich olive oil roundup.
