6 reasons to upgrade your vascular health.

Your vascular system is the delivery network that feeds every cell and organ you have, including your heart and your brain. It's easy to overlook, but it quietly underpins how you age. When your arteries and blood flow are at their best, so are you. Olivea delivers 20 mg of hydroxytyrosol, the olive polyphenol most studied for vascular health, in one daily capsule.

  1. The system behind every other system.

    You think about your heart and your brain, but rarely the network that feeds them. Your arteries carry oxygen and nutrients to every cell you have, which is why vascular health quietly sits underneath energy, cognition, and how you age. Take care of the delivery system, and everything downstream benefits.

    Your vascular network spans an estimated 60,000 miles.

  2. The olive polyphenol behind the benefit.

    You've heard olive oil is good for you, and the active reason is a polyphenol called hydroxytyrosol. It's the compound EFSA recognizes for contributing to the protection of blood lipids from oxidative stress. Most olive oil carries only a trace, so the amount you actually get is what matters.

  3. Studied for how your arteries respond.

    This is where the research gets interesting for you. In a 2023 clinical trial, daily hydroxytyrosol-enriched olive oil was associated with measurable improvement in endothelial function, how well arteries dilate and respond. That flexibility is one of the clearest markers of youthful, healthy blood vessels.

  4. A food, not a prescription.

    You're not adding another pill to your medicine cabinet. You're adding the active polyphenol in extra virgin olive oil, the molecule behind the Mediterranean diet's reputation for heart and vessel health for thousands of years. Olivea concentrates a meaningful dose into one easy capsule.

  5. Cardiologist-developed. Lab-verified.

    You shouldn't have to wonder what's in the capsule you swallow every morning. Olivea was developed with a Harvard-trained cardiologist and a medical advisory board of world-renowned physicians. The capsule-in-capsule design pairs a concentrated olive fruit extract with extra virgin olive oil, the natural matrix the molecule was studied in. Every batch you receive is third-party tested for purity and potency.

    You don't have to overhaul anything. Olivea is one daily capsule that supports the system feeding every part of you, from the inside out. The benefit is tied to consistent daily intake, so the easiest habit is the one that actually pays off. Better arteries, better you.

Grocery-store extra virgin olive oil typically carries ~100 mg/kg total polyphenols after shelf time. Matching Olivea's 36 mg from oil alone ≈ 400 ml of oil daily (~13 shots, ~3,300 calories). Hydroxytyrosol is one specific polyphenol within that total — and the only one with an EFSA-recognized health claim for protection of LDL from oxidative damage. Individual oils vary.

Hydroxytyrosol is one of the most powerful antioxidants found in nature. Its job is to neutralize harmful molecules and curb the oxidizing of LDL cholesterol. Most people won't realistically consume enough olive oil to get a meaningful amount of hydroxytyrosol in their diet, so I love that Olivea has included such a significant dose to help fill any nutrient gaps.

Why Olivea?

Most supplements miss the molecule that matters. Olivea delivers 20 mg of hydroxytyrosol — the polyphenol with the only EFSA-recognized health claim for protection of LDL from oxidative damage — suspended inside a capsule of real extra virgin olive oil your body actually absorbs.

Ingredients & sourcing

200 mg of olive fruit extract (Olea europaea) standardized to deliver 20 mg of hydroxytyrosol, suspended inside 400 mg of extra virgin olive oil — a capsule-in-capsule design that preserves the natural oil matrix the molecule needs to absorb.

Other ingredients: vegetable capsule, dextrin, silicon dioxide.

Sourced from early-harvest Koroneiki olives in Messinia, Greece.

How to take it

One capsule daily with or without food — ideally in the morning with your coffee. Safe to take alongside omega-3s, multivitamins, and other daily supplements. Always consult your physician before adding any new supplement to a prescription routine.

Lab analysis

Every batch is third-party tested for purity and potency. Polyphenol content is verified by HPLC; heavy metals, microbials, and pesticide residues are screened on every lot.

From the founder

Why we built Olivea.

After my father's sudden heart attack, I became obsessed with the daily cardiovascular habits I wish he'd had. Hydroxytyrosol is the most-studied olive polyphenol in the world — and the only one EFSA recognized for protection of LDL from oxidative damage. Olivea exists to make that science a daily habit, accessible to anyone.

Common questions.

I feel healthy. Why start now?

Because cardiovascular changes begin quietly, often decades before any symptom, and the protective effect of olive polyphenols on LDL is tied to consistent, long-term intake. Starting while you feel good is the point. The earlier the daily habit begins, the more time it has to compound. If heart disease runs in your family, that head start matters even more.

How is this different from taking olive oil?

A 30 ml shot of typical extra virgin olive oil delivers roughly 1–3 mg of hydroxytyrosol — and costs you ~250 calories per dose. Each Olivea capsule delivers 20 mg in a single 5-calorie capsule (4× the EFSA threshold). The capsule-in-capsule design (200 mg of olive fruit extract suspended inside 400 mg of EVOO) preserves the oil matrix the molecule needs to absorb properly.

Is hydroxytyrosol safe for long-term daily use?

Hydroxytyrosol is among the most well-tolerated compounds in nutrition research — it's a food-derived molecule the EFSA officially recognized as safe at therapeutic doses. Studies have followed daily supplementation for 6+ months with no reported adverse effects in healthy adults.

Is this safe to take with statins?

Olive polyphenols are food-derived and generally well tolerated. As with any supplement, talk to your doctor before adding it to a prescription routine.

How long until I notice anything?

You may not feel anything change day to day — and that's the nature of a quiet, protective ritual. Decades of research on olive polyphenols and the Mediterranean diet consistently link sustained, daily intake to better long-term cardiovascular outcomes. Some people do notice changes in how they feel over time; many simply take it knowing it's working in the background.

Where is it sourced?

Greece. From early-harvest Koroneiki olives in Messinia, selected for ultra-high-phenolic content. Lab tested for purity and potency, every batch.
