Enzogenol is a powerful formulation of antioxidant bioflavonoids extracted from the bark of the New Zealand Pine (Pinus radiata) that is comparable to flavonoid formulations of other pine bark extracts. The flavonoids found in Enzogenol have been shown in clinical and non-clinical studies to support cardiovascular health and to protect cells and tissues from the damaging effects of oxidative stress. NOW® Enzogenol also contains Rutin and Grape Seed Extract for their synergistic antioxidant benefits.
