Hydrovas® 10 (Olive Hydroxytyrosol Extract)

Olea europaea
Evidence Level
Moderate
2 Clinical Trials
3 Documented Benefits
3/5 Evidence Score

Hydrovas® 10 is a branded water-soluble olive (Olea europaea) fruit extract from Bionap standardized to 10–12% hydroxytyrosol plus tyrosol, marketed for cardiovascular and antioxidant support. Hydroxytyrosol is one of the most potent dietary antioxidants and carries an authorized EFSA health claim: olive-oil polyphenols protect blood lipids from oxidative damage at 5 mg/day of hydroxytyrosol and derivatives. Honest framing: the class evidence is strong; Hydrovas 10's own branded trials are not separately PubMed-indexed.

Studied Dose 50–100 mg/day of the extract; the EFSA claim is met at 5 mg/day of hydroxytyrosol and its derivatives. Take with food.
Active Compound Water-soluble olive (Olea europaea) fruit extract standardized to 10–12% hydroxytyrosol and tyrosol. Hydrovas® 10 is manufactured by Bionap.

Benefits

Protects blood lipids from oxidation (EFSA-authorized claim)

Hydroxytyrosol and related olive polyphenols carry an authorized EFSA health claim for protecting LDL cholesterol from oxidative damage at 5 mg/day — a rare, regulator-backed benefit. Hydrovas 10 delivers this active.

Supported by Trial 2, Trial 1

Cardiovascular support

Olive polyphenol extracts have improved blood pressure and cardiovascular markers in randomized trials, consistent with the Mediterranean-diet evidence base.

Supported by Trial 1

Potent antioxidant / anti-inflammatory action

Hydroxytyrosol is among the most potent dietary antioxidants, with documented anti-inflammatory activity supporting general antioxidant intake.

Supported by Trial 2

Mechanism of action

1

LDL oxidation protection

Hydroxytyrosol incorporates into lipoproteins and neutralizes free radicals, protecting LDL cholesterol from the oxidation that drives atherosclerosis — the basis for the EFSA claim.

2

Endothelial and anti-inflammatory effects

Olive polyphenols support nitric-oxide-mediated vascular function and dampen inflammatory signaling, contributing to cardiovascular benefit.

Clinical trials

1
Olive Polyphenol Cardiovascular RCT (component)

Double-blind, placebo-controlled randomized trial of olive extracts on blood pressure and cardiovascular markers (PLoS One, 2026).

Adults

Olive extract supplementation improved blood pressure and cardiovascular-health markers versus placebo — generic support for Hydrovas 10's hydroxytyrosol.

2
Olive polyphenol antioxidant evidence

Reviews of olive polyphenols plus the EFSA opinion underpinning the authorized health claim.

General adult population

Olive polyphenols (hydroxytyrosol) show strong antioxidant and anti-inflammatory activity, and the EFSA claim authorizes the LDL-protection benefit at 5 mg/day.

Side effects and drug interactions

Common Potential side effects

Generally very well tolerated; olive polyphenols are part of the Mediterranean diet.
Mild gastrointestinal upset possible.
Allergy to olive is uncommon but possible.
No significant safety concerns at recommended intakes.

Important Drug interactions

Antihypertensives: possible mild additive blood-pressure lowering.
Anticoagulants/antiplatelets: theoretical mild additive effect at high polyphenol intakes.
Generally a very low-interaction, food-derived profile.

Frequently asked questions about Hydrovas® 10 (Olive Hydroxytyrosol Extract)

What is Hydrovas 10?

Hydrovas 10 is a branded, water-soluble olive fruit extract from Bionap standardized to 10–12% hydroxytyrosol and tyrosol, taken for cardiovascular and antioxidant support. Hydroxytyrosol is one of the most potent dietary antioxidants.

Is the heart benefit actually proven?

Olive polyphenols carry an authorized EFSA health claim for protecting blood lipids from oxidative damage at 5 mg/day of hydroxytyrosol — a regulator-backed benefit — and randomized trials show cardiovascular improvements. Hydrovas 10's own branded trials are not separately PubMed-indexed, but the class evidence is strong.

What is Hydrovas 10 used for?

Hydrovas 10 is researched primarily for Cardiovascular and Antioxidant. Hydroxytyrosol and related olive polyphenols carry an authorized EFSA health claim for protecting LDL cholesterol from oxidative damage at 5 mg/day — a rare, regulator-backed benefit. Hydrovas 10 delivers this active.

What is the recommended dosage of Hydrovas 10?

The clinically studied dose is 50–100 mg/day of the extract; the EFSA claim is met at 5 mg/day of hydroxytyrosol and its derivatives. Take with food. Always follow the product label and check with a healthcare provider for personal advice.

Is Hydrovas 10 safe, and does it have side effects?

For most healthy adults, Hydrovas 10 is well tolerated at studied doses. Reported effects can include: Generally very well tolerated; olive polyphenols are part of the Mediterranean diet. Mild gastrointestinal upset possible. It may also interact with some medications. Hydrovas 10 is not right for everyone, so check with a healthcare provider first if you are pregnant or breastfeeding, have a medical condition, or take prescription medication.

Does Hydrovas 10 interact with any medications?

Possible interactions include: Antihypertensives: possible mild additive blood-pressure lowering. Anticoagulants/antiplatelets: theoretical mild additive effect at high polyphenol intakes. If you take prescription medication, check with a pharmacist or doctor before using it.
