Vitamin C helps fight cell-damaging free radicals in the body, which may contribute to the premature aging of cells. Human beings cannot produce Vitamin C on our own, so we have to get it in our diets. Unfortunately, the average diet often lacks the key nutrients from fruits and vegetables. Vitamin C also promotes immune system function. This product is specially formulated to provide a gradual release of Vitamin C over a prolonged period of time. Adults can take one tablet daily.
