High Dose Vitamin C
Vitamin C, or ascorbic acid, is a water-soluble vitamin. Unlike most mammals, humans do not have the ability to make their own vitamin c and must obtain it from supplementation or diet. Vitamin C is essential for multiple reactions in the body such as collagen production, immune system activation, metabolism support and acts as a potent antioxidant. Studies indicate that higher blood levels of vitamin C are associated with lower risk of death from cancer and cardiovascular disease. There is no scientific evidence that large amounts of vitamin C exert any adverse or toxic effects.
