Pine bark extract, most commonly available as Pycnogenol derived from French maritime pine, is a rich source of proanthocyanidins and other polyphenolic compounds with potent antioxidant properties. Research suggests it may support cardiovascular health by promoting healthy blood circulation and assisting with blood pressure regulation, while studies indicate potential benefits for skin elasticity, ADHD symptom management in children, and mild improvements in asthma-related markers. Some clinical investigations have also explored its role in supporting sexual function and libido, particularly in combination with other nutrients. While the body of evidence is growing and generally promising across these areas, study sizes have often been modest, and researchers continue to explore the full scope of its effects and the populations most likely to benefit.
