Vitamin B6 AND Vitamin B12
Vitamin B6 is a naturally occurring compound that is essential to the maintenance of good health. This water-soluble vitamin assists in amino acid metabolism (hommocysteine), glycogen metabolism and degradation (Vitamin B6 is required for glycogen phosphorylase activity), and impacts the action of steroid hormones and gene expression. Vitamin B6 is needed as a coenzyme for many reactions involved in amino acid metabolism.
These include: transamination reactions, which transfer amino groups from amino acids to ketoacids to produce new amino acids; deamination reactions, which remove the amine group from amino acid so they can be used to produce energy or to synthesize glucose; and decarboxylation reactions, which remove the acid group (-COOH) from amino acid so the remaining molecule can be used to synthesize neurotransmitters and other non-protein molecules that contain nitrogen.
Vitamin B6 improves immune function, and reduces cardiovascular threats by metabolizing homocysteine. Homocysteine is an intermediate in methionine metabolism – high concentrations of homocysteine in blood will lead to artherosclerosis.
Vitamin B12 is a naturally occurring water-soluble compound that is essential for the maintenance and regulation of blood plasma. Vitamin B12 is not synthesized by humans (or animals and plants) and must be consumed in adequate dietary concentrations.
As a result, most sources of Vitamin B12 are ergogenic or from foods that have been fortified with this necessary vitamin. Vitamin B12 is required for the maintenance of myelin (nerve insulation responsible for proper nerve transmission), and helps to produce red blood cells and treat pernicious anemia (a fatal form of anemia that does not respond to iron supplementation).
