Overview

NOW Foods Olive Leaf Extract provides 500mg of olive leaf extract standardized to 18% oleuropein (90mg per capsule). Oleuropein is the primary bioactive compound in olive leaves with potent antioxidant, antimicrobial, and anti-inflammatory properties. Clinical research shows olive leaf extract supports immune function, cardiovascular health (reduces blood pressure and LDL oxidation), and blood sugar regulation. The 120-capsule count provides a 2-4 month supply depending on dosing.
