All living organisms utilize oxygen to metabolize and use dietary nutrients in order to produce energy for survival. Oxygen is a vital component for living. Oxygen mediates chemical reactions that metabolize fats, proteins, and carbohydrates to produce energy. While oxygen is one of the most essential components for living, it is also a double edged sword. Oxygen is a highly reactive atom that is capable of becoming part of potentially damaging molecules commonly called “free radicals.” “Free radicals” attack healthy cells in the body and may lead to damage or disease. Scientists believe free radicals contribute to aging, as well as the development of a number of health problems, including heart disease and cancer. Antioxidants are substances that destroy the “free radicals” and help to reduce the damage done to the body. There are 3 main types of antioxidants found in nature: Antioxidant Enzymes, Antioxidant Vitamins (Vitamin C, Vitamin E) and Antioxidant Phytochemicals (Flavonoids, Polyphenols) Our Organic Grapeseed (OPC) Antioxidant Tablet contains one of these powerful antioxidant phytochemicals: Proanthocyanidins. Proanthocyanidins (PAs), a class of polyphenols, are very powerful antioxidants. Studies indicate that the antioxidant power of proanthocyanidins is 20 times higher than that of vitamin C and 50 times higher than vitamin E. That’s the reason we chose it for our product. Ooops, did we forgot to mention that it’s certified organic, gluten-free, vegan-friendly, non-GMO and contains no synthetic chemicals or additives!
