Hytolive(R)-Olive Fruit Extract
Also known as: Olea europaea (olive fruit extract), Hytolive®, olive polyphenols, olive extract, Olive fruit extract
Overview
Hytolive®, a standardized olive fruit extract from Olea europaea, is a polyphenol-rich supplement valued for its antioxidant and cardiometabolic benefits. Key bioactive compounds include hydroxytyrosol, oleuropein, and tyrosol. It is used to support cardiovascular health, reduce oxidative stress, and exert anti-inflammatory effects. Research suggests that olive polyphenols can improve blood pressure, LDL cholesterol levels, and overall antioxidant capacity. Hytolive® is often combined with selenium to enhance its antioxidant activity. While research maturity is moderate, with several RCTs and meta-analyses, more extensive, long-term studies are needed to fully elucidate its benefits. The available evidence is strongest for its antioxidant and cardiometabolic effects.
Benefits
Olive fruit extract, particularly its polyphenol components like oleuropein, hydroxytyrosol, and tyrosol, offers several evidence-based benefits. Meta-analyses indicate improvements in cardiometabolic parameters, including a reduction in systolic blood pressure (approximately 3-5 mmHg) and LDL cholesterol (approximately 5-10 mg/dL). These polyphenols also enhance antioxidant capacity and reduce oxidative stress markers. Benefits are most pronounced in adults with cardiovascular risk factors or metabolic syndrome. While effect sizes are modest compared to pharmaceutical interventions, the observed reductions in blood pressure and LDL cholesterol are clinically meaningful. Benefits typically manifest within 4-12 weeks of consistent supplementation.
How it works
Olive fruit extract exerts its effects primarily through antioxidant mechanisms. Its polyphenols scavenge free radicals, inhibit LDL oxidation, and activate endogenous antioxidant enzymes. These actions influence cardiovascular and metabolic systems, impacting gut microbiota and inflammatory pathways. Key molecular targets include NF-κB and Nrf2, redox-sensitive signaling pathways involved in inflammation and cellular defense. Hydroxytyrosol and oleuropein, major components of the extract, are well-absorbed, reaching peak plasma concentrations within 1-2 hours after ingestion.
Side effects
Olive fruit extracts are generally well-tolerated. Common side effects are rare, with only mild gastrointestinal discomfort occasionally reported. Uncommon side effects, occurring in 1-5% of users, may include mild headaches or dizziness. Rare side effects, affecting less than 1% of users, include allergic reactions. No significant drug interactions have been reported in clinical studies, although there is a theoretical potential for additive effects with antihypertensive or anticoagulant drugs. Contraindications are not well-established, but caution is advised for individuals with known olive allergies. While considered safe for most adults, there is insufficient data on its use in children, pregnant women, or lactating women.
Dosage
The minimum effective dose of olive fruit extract is approximately 50 mg/day of hydroxytyrosol or an equivalent polyphenol content. Optimal dosage ranges are between 100-500 mg/day of a standardized olive fruit extract. Dosages up to 1,000 mg/day have been used in studies without significant adverse effects. The extract can be taken with or without food, as food intake may enhance absorption. Standardized extracts are preferred to ensure consistent polyphenol content. No specific cofactors are required for its absorption or activity.
FAQs
Is olive fruit extract safe?
Olive fruit extract is safe for most adults at recommended doses. Allergic reactions are rare. Consult a healthcare provider if you have concerns.
When should I take olive fruit extract?
It can be taken at any time of day. There is no strong evidence suggesting that timing affects efficacy.
What results can I expect?
Expect modest improvements in blood pressure, cholesterol, and antioxidant status within 4-12 weeks. It is not a substitute for pharmaceutical therapy.
Can I take it with my other medications?
While no significant drug interactions have been reported, consult your healthcare provider if you are taking antihypertensive or anticoagulant medications.
What is the best form of olive fruit extract to take?
Standardized extracts are preferred to ensure consistent polyphenol content, particularly hydroxytyrosol and oleuropein.
