The Vitamin Shop Vitamin C Calcium Ascorbate - 1000 mg - Vitamin C is a powerful vitamin with infection-fighting properties, playing a large role in immune system function. Vitamin C is crucial for the formation of collagen, making it very important for wound repair, healthy gums, strong bones and teeth, and in the prevention of bruising. As an antioxidant, it protects the aqueous areas of the body from free radicals. Because it is a water-soluble vitamin, the body cannot store vitamin C, making regular supplementation vital. The Vitamin Shop's Vitamin C formula is buffered with calcium and recommended for individuals who experience gastrointestinal discomfort with supplementation of vitamin C. It can be taken therapeutically at higher daily doses without gastrointestinal side effects. Calcium Ascorbate also replenishes the calcium that is excreted in the urine due to the chelating properties of vitamin C. Calcium also allows vitamin C to remain in the cells for a longer period.
