Vitamin B-12 (cobalamin) is a water-soluble vitamin that is a cofactor for cell metabolism, red blood cell formation, neurotransmitter production, hormone regulation, and DNA synthesis. B12 provides energy, clarity of mind and memory, enhanced sleep, mood, immune system, physical stamina and aides in weight management. Methylcobalamin (B12) injections are an effective way to compensate for the lack of dietary intake and are 100% absorbed. The methyl-B12 benefits will vary from person to person. Some feel an effect the same day, others may feel it a few days later.

 B12 Forms

Cyanocobalamin injections are the least expensive; however they are synthetic, contain cyanide, and not very effective. Hydroxocobalamin is a natural form of B12 that works well providing many benefits. The most effective form of B12 is methylcobalamin. This is the active form of B12 that the body uses in hundreds of metabolic pathways. It is the fastest and longest acting form of B12 and is especially beneficial for the nervous system.


Methylcobalamin injections are safe for all ages and do not interfere with medications. Those with Leber's disease or cobalt allergies should avoid B12 injections.
