The bark of French maritime pine (Pinus pinaster) produces a standardized extract called Pycnogenol. It delivers a mix of procyanidins, bioflavonoids, and phenolic acids that promote circulation and antioxidant activity.
People take it primarily to support blood flow, ease joint discomfort, and maintain skin health by protecting collagen. Some also use it for immune support and to aid post-exercise recovery.
You can take it as a capsule, often once or twice daily with food, or find it in topical creams. Mild stomach upset may occur. The extract can interact with blood pressure or anticoagulant medications. People with autoimmune conditions should be cautious. If pregnant or nursing, consult a healthcare professional before use.
