3 Documented Benefits
4/5 Evidence Score

Hytolive® (PLT Health Solutions) is a natural olive (Olea europaea) fruit polyphenol extract standardized for hydroxytyrosol — the primary bioactive responsible for extra virgin olive oil's exceptional cardiovascular and antioxidant benefits. Hydroxytyrosol is one of the most potent natural antioxidants known (ORAC value surpassing resveratrol and vitamin C), with an EU-authorized health claim for protecting LDL from oxidative stress. Hytolive® provides this olive oil benefit in a stable, concentrated supplement form without the calories of olive oil.

Studied Dose 5–20 mg/day hydroxytyrosol (as Hytolive®); EU health claim: ≥5 mg/day hydroxytyrosol from olive products; cardiovascular studies: 10–30 mg/day
Active Compound Hydroxytyrosol and olive polyphenols (oleuropein, tyrosol, oleocanthal derivatives) — Hytolive® by PLT Health Solutions; standardized Olea europaea fruit extract from Spanish olive processing; EU-authorized health claim ingredient

Benefits

LDL oxidation protection (EU-authorized health claim)

Hydroxytyrosol from olive oil has an EU-authorized health claim (EC No 432/2012) stating that 'olive oil polyphenols contribute to the protection of blood lipids from oxidative stress' at doses of ≥5 mg/day hydroxytyrosol. This regulatory recognition is exceptionally rare for a dietary ingredient, confirming the strong evidence base for hydroxytyrosol's antioxidant cardiovascular protection.

Supported by Trial 1

Cardiovascular health and blood pressure support

Olive polyphenols reduce cardiovascular risk through multiple mechanisms: LDL oxidation prevention, endothelial function improvement, mild antihypertensive activity, reduced platelet aggregation, and anti-inflammatory COX-1/2 inhibition (oleocanthal). Clinical studies confirm significant blood pressure reduction and improved cardiovascular biomarkers with olive polyphenol supplementation.

Supported by Trial 1

Exceptional antioxidant protection

Hydroxytyrosol has an ORAC (oxygen radical absorbance capacity) value of approximately 68,000 — among the highest measured for any natural compound, far exceeding resveratrol (14,000), vitamin C (3,000), and vitamin E (1,500). This antioxidant potency provides broad cellular protection against oxidative stress relevant to aging, cardiovascular disease, and cancer prevention.

Mechanism of action

1

Hydroxytyrosol catechol group free radical scavenging and eNOS activation

The catechol (ortho-dihydroxybenzene) moiety of hydroxytyrosol provides exceptional electron-donating capacity for free radical neutralization through hydrogen atom transfer and single electron transfer mechanisms. Simultaneously, hydroxytyrosol activates the Nrf2/are pathway, upregulating endogenous antioxidant enzymes (superoxide dismutase, catalase, glutathione peroxidase) for amplified cellular antioxidant protection. The combined direct scavenging and Nrf2 induction explains hydroxytyrosol's superior antioxidant activity relative to structurally simpler polyphenols.

Clinical trials

1
Olive Polyphenols for Cardiovascular Markers — RCT
PubMed

Multiple randomized, double-blind, placebo-controlled trials examining olive polyphenol (hydroxytyrosol) supplementation effects on cardiovascular risk markers. EFSA-approved Article 13.5 health claim ('olive oil polyphenols contribute to the protection of blood lipids from oxidative stress') requires ≥5 mg hydroxytyrosol and its derivatives (e.g., oleuropein, tyrosol) per day. (Multiple supporting trials)

Pooled across hydroxytyrosol/olive polyphenol trials.

Olive polyphenol supplementation (≥5 mg/day hydroxytyrosol) reduced LDL oxidation markers, modestly improved endothelial function, and reduced inflammatory markers. EFSA-approved 'protection of LDL from oxidative damage' claim is one of the most rigorous food health claims in EU. Note: this claim is well-evidenced; broader clinical outcome benefits (CV events, mortality) are inferred from Mediterranean diet literature, not directly demonstrated for isolated olive polyphenol supplements.

Side effects and drug interactions

Common Potential side effects

Excellent safety profile; olive polyphenols are normal dietary components
Mild GI effects at high doses — take with food
Olive allergy (very rare) — discontinue if reaction

Important Drug interactions

Antihypertensive medications — additive blood pressure lowering at higher doses; monitor
Antiplatelet/anticoagulants — mild antiplatelet activity; monitor if on blood thinners
No significant pharmacokinetic drug interactions at standard doses

Frequently asked questions about Hytolive® (Olive Fruit Polyphenols / Hydroxytyrosol)

What is Hytolive?

Hytolive® (PLT Health Solutions) is a natural olive (Olea europaea) fruit polyphenol extract standardized for hydroxytyrosol — the primary bioactive responsible for extra virgin olive oil's exceptional cardiovascular and antioxidant benefits.

What is Hytolive used for?

Hytolive is researched primarily for Cardiovascular, Antioxidant, and Anti-Inflammatory. Hydroxytyrosol from olive oil has an EU-authorized health claim (EC No 432/2012) stating that 'olive oil polyphenols contribute to the protection of blood lipids from oxidative stress' at doses of ≥5 mg/day hydroxytyrosol.

What is the recommended dosage of Hytolive?

The clinically studied dose is 5–20 mg/day hydroxytyrosol (as Hytolive®); EU health claim: ≥5 mg/day hydroxytyrosol from olive products; cardiovascular studies: 10–30 mg/day Always follow the product label and check with a healthcare provider for personal advice.

Is Hytolive safe, and does it have side effects?

For most healthy adults, Hytolive is well tolerated at studied doses.
