Vitamin B12 is a water-soluble vitamin found mainly in foods of animal origin. It is therefore particularly important for people on a strict vegetarian diet. The methylcobalamin form of B12 is superior to the more common cyanocobalamin form, because it acts immediately upon absorption, rather than having to undergo transformation to become active.
Vitamin B12 has many functions in the body. It prevents anemia, helps regulate red blood cell formation along with folic acid, and promotes iron utilization. It also plays an important role in energy production and in the formation of DNA and RNA. In terms of the nervous system, it is primarily involved in the production of neurotransmitters that aid memorization and learning, and contributes to brain health by slowing age-related cognitive decline.
Methylcobalamin is essential for the conversion of homocysteine to methionine, and therefore plays a key role in protein synthesis for cardiovascular function. As such, it is important for the maintenance of cardiovascular health and good health.
