Vitamin B-12 is a critcal cofactor in the production of energy from fats and proteins, and is known for its critical role in cell growth, DNA synthesis, cell replication, and recycling of homocysteine – a potentially toxic oxidizing metabolite. In the diet, Vitamin B-12 is obtained only from animal proteins and requires intrinsic factor (IF) in the stomach to be absorbed.

When Vitamin B12 succeeds at entering the bloodstream it then must be converted to an active coenzyme before it is beneficial to our health. Three steps are required to convert the manmade B12 you encounter in many vitamin supplements (called cyanocobalamin) into methylcobalamin, the body ready coenzyme of B12 provided in the HS Fighters formula.

Step one of the conversion sequence above is for your body to remove a molecule of cynanide from cyanocobalamin, although the amount cyanide in this form of B12 is not considered toxic.

Dose for dose, there is substantially greater retention of useable B12 when taking methylcobalamin as a supplement ingredient. The amount of B12 (simple cobalamin) excreted in the urine after a dose of methylcobalamin is about one-third that of a similar dose of cyanocobalamin. It takes approcximately 1-2 months for cyanocobalamin to be converted to active B12, assuming an adequate supply of necessary cofactors is available.

Both the oral and the sublingual forms of methylcobalamin B12 are identically effective at doses of at least 500 mcg.
