Antioxidant 0.5% per year with an increase to 4.5% per year at UA supersaturation levels (535+ μmol/L). Many of these aforementioned studies determined UA's antioxidant actions within normal physiological levels, and some found antioxidant activity at levels as high as 285 μmol/L. Ascorbic acid or "vitamin C" is a monosaccharide oxidation-reduction (redox) catalyst found in both animals and plants. As one of the enzymes needed to make ascorbic acid has been lost by mutation during primate evolution, humans must obtain it from the diet; it is therefore a vitamin. Most other animals are able to produce this compound in their bodies
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
