Vitamin C the red blood cells have evolved a mechanism to more efficiently utilize the vitamin C present in the body by recycling oxidized -dehydroascorbic acid (DHA) back into ascorbic acid for reuse by the body. The mechanism was not found to be present in mammals that synthesize their own vitamin C. Vitamin C megadosage is a term describing the consumption or injection of vitamin C in doses comparable to or higher than the amounts produced by the livers of mammals which are able to synthesize vitamin C. The theory behind this, although not the actual term, was described in 1970 in
Vitamin B12 "Corynebacterium", "Flavobacterium", "Lactobacillus", "Micromonospora", "Mycobacterium", "Nocardia", "Protaminobacter", "Proteus", "Rhizobium", "Salmonella", "Serratia", "Streptococcus" and "Xanthomonas" . Six Nobel Prizes have been awarded for direct and indirect studies of vitamin B. Vitamin B12 Vitamin B, also called cobalamin, is a water-soluble vitamin that is involved in the metabolism of every cell of the human body: it is a cofactor in DNA synthesis, and in both fatty acid and amino acid metabolism. It is particularly important in the normal functioning of the nervous system via its role in the synthesis of myelin, and in the maturation of developing red blood cells in the
