Methylcobalamin is a cobalamin which is a naturally occurring form of Vitamin B12. A person can get Methylcobalamin through either food sources or supplements. Methylcobalamin is bioavailable and is active immediately after absorption by the human body.

The body will still need to remove and eliminate this compound.

Methylcobalamin supplements made from bacterial sources of B12 are a more effective and direct source of B12. This form of B12 is called a coenzyme form of B12 and is believed to be a much more active form of the vitamin. A coenzyme form of the vitamin means the vitamin is ready to be processed and absorbed by the body with need for additional carriers.

Both cyanocobalamin and methylcobalamin can be taken orally in the form of tablets, capsules, lozenges, liquid drops though injections and nasal spray forms are also available.

Examples of inactive ingredients that can be added in the formulation are microcrystalline cellulose, sodium stearyl fumarate, xylitol.
