Overview

Pine Bark Extract, particularly the branded form Pycnogenol, is derived from the bark of the French maritime pine (Pinus pinaster). It is rich in procyanidins — powerful antioxidants that support blood vessel health, circulation, and reduce oxidative stress. Pine bark extract has been extensively researched for its effects on cardiovascular health, inflammation, and skin health.

Pycnogenol is one of the most studied forms of pine bark extract, with over 160 clinical trials supporting its benefits. It is commonly used to support healthy blood flow, reduce inflammation, and promote skin health from within. The extract is standardized to contain 65–75% procyanidins for consistent potency.
