Vitamin C benefit:

Ascorbic acid, or vitamin C, aids in many functions of the body, including the absorption of iron. Large doses of C do not usually cause toxicity because, as a water-soluble vitamin, it is simply excreted in the urine. People who tend to form kidney stones may find their condition aggravated by vitamin C supplementation or megadosing.
