Overview

NOW Olive Leaf Extract provides 500mg of olive leaf extract per capsule, standardized to 6% oleuropein (30mg). Oleuropein is the primary bioactive compound in olive leaves with potent antioxidant, antimicrobial, and cardiovascular benefits. Research shows oleuropein can lower blood pressure, reduce LDL oxidation, support immune function against viral and bacterial infections, and provide antioxidant protection 400% greater than vitamin C. Olive leaf extract is a cornerstone of Mediterranean traditional medicine and has been used for centuries for immune and cardiovascular support.
