What is Olive Leaf Extract?
Olive leaf extract concentrates oleuropein, the same polyphenol family that makes extra-virgin olive oil heart-protective. Controlled trials show standardized olive leaf extract can modestly lower blood pressure and improve markers of vascular function and cholesterol, while laboratory work points to the antioxidant and antimicrobial activity behind its traditional use for immune support. Effects are gentle and build over weeks, so it suits long-term cardiovascular maintenance rather than acute use. Choose an extract standardized to 16 to 20 percent oleuropein, typically 500 to 1000 mg daily with food.
