Why It Works
Standardized to 20% oleuropein — the active polyphenol behind olive leaf's remarkable health properties. Here's what the science shows.
Oleuropein has been shown in clinical trials to reduce systolic and diastolic blood pressure, making it a natural ally for cardiovascular wellness. A 2011 randomized trial found effects comparable to an ACE inhibitor.
📄 Phytomedicine, 2011 — Phytomedicine 2011;18(4):298-301Olive leaf's antimicrobial and antiviral properties stem from oleuropein and elenolic acid. Studies demonstrate activity against a broad spectrum of pathogens, supporting immune defense year-round.
📄 Mycoses, 2002;45(8):286-91Oleuropein may protect neurons against oxidative stress and inflammation. Animal and in vitro studies suggest it helps reduce amyloid plaque formation associated with cognitive decline.
📄 Neurochem Int., 2012;61(5):741-52Research indicates oleuropein can improve insulin sensitivity and stimulate insulin secretion from pancreatic beta cells — a benefit for those managing blood glucose and metabolic health.
📄 J Nutr Biochem., 2013;24(8):1420-7Olive leaf extract has demonstrated the ability to inhibit fat cell formation and reduce fat accumulation in preclinical models, while also modestly boosting thermogenesis in brown adipose tissue.
📄 J Nutr., 2008;138(11):2265S-2271SOleuropein is one of the most potent natural antioxidants studied. It scavenges free radicals, inhibits pro-inflammatory cytokines (IL-1β, TNF-α), and reduces oxidative stress markers systemically.
📄 Int J Mol Sci., 2014;15(1):523-33Usage Guide
Simple, consistent use is the key to experiencing the full benefits of olive leaf extract.
Take one to two capsules with a full glass of water. Best taken in the morning with breakfast to support digestion and absorption.
For best results, take olive leaf extract at the same time each day. Most users begin noticing benefits within 2–4 weeks of regular use.
We recommend a minimum 4–6 week commitment before evaluating results. Many cardiovascular and immune benefits build cumulatively over time.

Research & Evidence
Our formulation is informed by peer-reviewed research. Here are key studies supporting the benefits of olive leaf extract.
A double-blind, randomized clinical trial comparing olive leaf extract to Captopril found comparable reductions in blood pressure, without the side-effect profile of pharmaceuticals.
Phytomedicine, 2011 — Susalit E, et al.
View on PubMed →Research demonstrated that olive leaf extract and its isolated compounds exhibit potent activity against common fungal and bacterial pathogens, supporting its role as a broad-spectrum immune modulator.
Mycoses, 2002 — Özcan M, et al.
View on PubMed →This study demonstrated that oleuropein directly stimulates insulin secretion from pancreatic beta cells and improves peripheral insulin sensitivity — key mechanisms for metabolic and blood sugar regulation.
