Facts on Vitamin C

Vitamin C also known as Ascorbic acid is a miracle vitamin involved in many biological processes of the body. Although it is readily available through a variety of foods, one needs to know the facts on Vitamin C and the doses of Vitamin C recommended for optimal health.
Facts on Vitamin C
According to a research published in Journal of Epidemiology (May 1992), individuals with high levels of Vitamin C in blood have greater longevity.
