Pine bark extract comes from the bark of the *Pinus pinaster* tree. The standardized form, often sold as Pycnogenol®, uses a proprietary extraction process that yields a consistent, high concentration of water-soluble procyanidins and bioflavonoids. This process helps with absorption and stomach comfort compared to less refined pine bark products.
People take it for circulation and vascular support, especially for leg vein comfort. Its antioxidant properties support skin health, joint flexibility, and exercise recovery by cutting down oxidative stress from workouts. Take it with a meal to improve absorption.
Watch out if you take blood pressure drugs or blood thinners, since pine bark affects circulation. Mild stomach upset can happen. Stop using it at least two weeks before any scheduled surgery.
