This product is an anti-anemia drug. Vitamin B12 is involved in methyl-conversion and folate metabolism in the body, promoting the conversion of 5-methyltetrahydrofolate to tetrahydrofolate. When deficient, it leads to impaired DNA synthesis and affects the maturation of red blood cells. This product also promotes the conversion of methylmalonic acid to succinic acid and participates in the tricarboxylic acid cycle. This effect is related to the synthesis of myelin lipids and the maintenance of myelinated nerve fiber function integrity, which may be related to nerve damage in vitamin B12 deficiency.
