Bilberry Extract
A potent anthocyanin-rich extract known for supporting night vision and retinal health.
Also known as: Vaccinium myrtillus • European Blueberry
Overview
Bilberry, a relative of the blueberry, is rich in powerful antioxidants called anthocyanins. Historically, British Royal Air Force pilots ate bilberry jam to improve their night vision during World War II. Modern research focuses on its ability to improve blood flow to the retina, strengthen capillaries, and protect against oxidative damage.
