Sell Vitamin B12 CAS NO.68-19-9

Vitamin B₁₂, also called cobalamin, is a water-soluble vitamin that has a key role in the normal functioning of the brain and nervous system, and the formation of red blood cells. It is one of eight B vitamins. It is involved in the metabolism of every cell of the human body, especially affecting DNAsynthesis, fatty acid and amino acid metabolism.^[1] No fungi, plants, nor animals (including humans) are capable of producing vitamin B₁₂. Only bacteriaand archaea have the enzymes needed for its synthesis. Proved sources of B₁₂ are animal products (meat, fish, dairy products) and supplements. Some research states that certain non-animal products possibly can be a natural source of B₁₂ because of bacterial symbiosis. B₁₂ is the largest and most structurally complicated vitamin and can be produced industrially only through a bacterial fermentation-synthesis. This synthetic B₁₂ is used to fortify foods and sold as a dietary supplement.
