Source Naturals Methylcobalamin, an active coenzyme form of vitamin B-12, is essential for cell growth and replication. It is more concentrated than other forms of B-12 in the cerebrospinal fluid where it can be used by the nervous system. It donates methyl groups to the myelin sheath that insulates certain nerve fibres. It may also play a role in maintaining a healthy sleep-wake cycle, as well as normal nerve function. Suitable for vegetarians. Cherry flavoured sublingual tablets, containing 1mg of vitamin B12. 60 tablets.
Vitamin B12
Vitamin B-12 is a water soluble vitamin, is unique in being the first cobalt-containing substance found to be essential for longevity, and is the only vitamin that contains essential mineral elements. The cobalt gives it its dark red colour. Vitamin B-12 and folic acid share a special relationship to cell division work. Vitamin B-12 has been known as the energiser (if already deficient, under stress, fatigued, or recovering from illness).
Vitamin B-12 is necessary for normal metabolism of nerve tissue and is involved in protein, fat and carbohydrate metabolism. It is closely related to the actions of four amino acids, pantothenic acid and vitamin c. It also helps iron function better in the body and aids folic acid in the synthesis of choline. B12 helps the placement of vitamin A into body tissues by aiding carotene absorption or vitamin A conversion. It also aids in the production of DNA RNA, the body's genetic material.
