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.1-8 Vitamin C also promotes the absorption of iron, while preventing its oxidation.9,10 Vitamin C is a vital cofactor to the formation of collagen, the connective tissue that supports arterial walls, skin, bones, and teeth.5-7

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.11-14 Physical stresses on the body such as ingestion of heavy metals,15-20 cigarette smoking,21-24 immune impairment,25-31 extreme temperatures,32-36 and chronic use of certain medications such as aspirin also signal the need for increased intake of vitamin C.37 In fact, a major immune-supporting activity of vitamin C is boosting glutathione levels in human lymphocytes,38 cells that make up about 25% of all white cells in the blood.

Because humans do not manufacture vitamin C internally, it must be obtained through dietary sources or supplements. Along with ascorbic acid, vitamin C also comes in at least two other forms: chemically bonded to minerals as ascorbates, and as the fat-soluble ascorbyl palmitate.39-41 Both of these forms are nonacidic. Mineral ascorbates, including magnesium ascorbate, are often recommended to people who experience gastrointestinal problems (abdominal pain or diarrhea) with ascorbic acid.
