General Comment
2011-03-23 An essential nutrient and antioxidant with possible anticancer role, especially with intravenous administration. A cofactor in several enzymatic reactions of living organisms, it is linked with effective wound healing and prevention or treatment of scurvy and gout. Also known as vitamin C, it is believed to boost the immune system. Humans alone of the primates require exogenous sources of daily vitamin C.
