Vitamin C 1000 mg

Vitamin C 1000 mg plays an important role in immune function and improves the absorption of nonheme iron, the form of iron present in plant-based foods.

Taking at least 200 mg of vitamin C per 30 mg of iron together increases nonheme iron absorption in adults. In children, adding 25-50 mg of Vitamin C daily can increase iron absorption from a meal by 3.2- 4.8-fold compared to eating the meal alone.

• Vitamin C, also known as ascorbic acid, is a water-soluble antioxidant that reacts directly with superoxide, hydroxyl radicals, and singlet oxygen.
• Vitamin C readily undergoes reversible oxidation and reduction in the body and has been shown to regenerate other antioxidants within the body, including alpha-tocopherol.
• It decreases oxidants in gastric secretions which may protect lipids in plasma and against peroxidative damage.
• Ascorbic acid is absorbed in the small intestine by a sodium-dependent transport process that is intake dependent.
• It is a specific electron donor for enzymes that participate in collagen hydroxylation and carnitine biosynthesis.
• This function is required to catalyze the crosslinking of collagen fibers which are essential for normal wound healing and capillary health.
• Vitamin C also appears to prevent inactivation of nitric oxide (NO)-mediated vasodilation.
