Vitamin C, or ascorbic acid, is a white, crystalline, water-soluble substance found in citrus fruits. As an antioxidant, vitamin C scavenges free radicals in the body and protects tissues from oxidative stress. Vitamin C also promotes the absorption of iron, while inhibiting its oxidation. Vitamin C is a vital cofactor to the formation of collagen, the connective tissue that supports arterial walls, skin, bones and teeth. More vitamin C is contained in the adrenal glands than any other organ in the body and is required at higher levels during times of stress.2 Physical stresses may also increase the need for vitamin C. Our Buffered Vitamin C Powder contains four buffering minerals, in addition to ascorbic acid. When mixed with water, it produces a reduced-acid solution that is non-irritating to the stomach and intestinal lining. The minerals also make it a more pleasant-tasting and healthful drink.
