Super C-1000 Complex from Puritans Pride delivers 1000mg of vitamin C per caplet. Vitamin C is a water-soluble vitamin that cannot be stored by the body. It must therefore be fed daily with food. It plays an important role in metabolism and contributes to the normal function of the immune system, to normal collagen formation (cartilage, blood vessels, bone function, skin, etc.), to normal nerve function and to normal mental function. Suggested use: take one capsule daily with enough liquid for a meal.
