Pterostilbene

More bioavailable cousin of resveratrol with better absorption and longer half-life

Pterostilbene is a stilbenoid found in blueberries and grapes, structurally similar to resveratrol but with two methoxy groups that significantly increase its oral bioavailability and half-life. Where resveratrol is rapidly metabolized, pterostilbene remains active in the body for hours.
