Pycnogenol is a compound of natural chemicals. It comes from the bark of a European pine tree.
Pycnogenol seems to be an antioxidant that helps protect cells from damage.
Pycnogenol is a trademarked brand name for a French formula. But similar compounds are in other products and foods. They include other pine bark extracts, grape seed extract, and peanut skins.
Tell your doctor about any supplements you're taking, even if they're natural. That way, your doctor can check on any potential side effects or interactions with any medications.
The U.S. Food and Drug Administration (FDA) does regulate dietary supplements; however, it treats them like foods rather than medications. Unlike drug manufacturers, the makers of supplements don’t have to show their products are safe or effective before selling them on the market.
