Cranberry extract comes from a small, tart red berry. Native to North America.
Cranberry Proanthocyanidin (OPC) is a bioflavonoid with a special molecular structure, and it is internationally recognized as the most effective natural antioxidant for scavenging free radicals in the human body. Experiments show that OPC’s anti-free radical oxidation ability is stronger than vitamin E and vitamin C, and it can be quickly and fully absorbed. The appearance of proanthocyanidins is generally reddish-brown powder, with a slight smell and astringent taste. It is soluble in water and most organic solvents. It is a new type of high-efficiency antioxidant with strong in vivo activity.
