An essential nutrient and a member of the B complex family of vitamins, vitamin B12 acts as a coenzyme for normal DNA synthesis, prevents nerve damage, and promotes growth and cell development.
Vitamin B12 aids folic acid in regulation of the formation of red blood cells, and helps in the utilization of iron. It is also required for the proper digestion and absorption of foods, the synthesis of proteins, and the metabolism of carbohydrates and fats. B12 plays a role in nervous system function with the production of myelin, the protective sheath around nerves, as well as the production of a neurotransmitter that helps with memory and learning.
Vitamin B12 is water-soluble and is the only B vitamin that can be stored in the body, mainly in the liver. Deficiencies are commonly linked to an inability to effectively absorb vitamin B12 from the intestine, or to individuals who consume a strict vegetarian diet, since the vitamin is found primarily in foods of animal origin.
Natural Factors Vitamin B12 is in the cyanocobalamin form which is the most stable form of vitamin B12. Each tablet offers 1000 mcg of vitamin B12 to help maintain good health.
