Product Description

Manufacturer: Life Extension

Vitamin C, or ascorbic acid, is a white, crystalline, water-soluble substance found in citrus fruits and green vegetables. As an antioxidant, vitamin C scavenges free radicals in the body and protects tissues from oxidative stress.15-18 Vitamin C also promotes the absorption of iron, while preventing its oxidation.19-21 Vitamin C is a vital cofactor to the formation of collagen, the connective tissue that supports arterial walls, skin, bones, and teeth.22-24*

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.25-28 Physical stresses on the body such as ingestion of heavy metals,29-34 cigarette smoking,35-38 infections,39-43 extreme temperatures,44-48 and chronic use of certain medications such as aspirin also signal the need for increased intake of vitamin C.49

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. Both of these forms are noN-acidic.
