How it works

Pine bark extract is primarily used to enhance blood flow and endothelial function by increasing nitric oxide production. It has strong clinical support for improving erectile dysfunction when combined with L-arginine and moderate evidence for supporting cognitive focus and skin health.

Rich in proanthocyanidins that stimulate endothelial nitric oxide synthase (eNOS) to relax blood vessels and provide potent systemic antioxidant protection.
