Methylcobalamin 1000mcg Nuggets, a naturally occuring form of vitamin B12 promotes the health of the circulatory and nervous systems and supports energy metabolism. Methylcobalamin is the methylated form of Vitamin B12. This form of B12 is the most active form of vitamin B12 in the brain and nervous system. Methylcobalamin is essential for cell growth and replication. This enzyme is required for the synthesis of the amino acid, methionine, from homocysteine. Functions of Methylcobalamin: B12 is vital for healthy cell growth and function. Methylcobalamin improves our brain function, memory and nervous system. Methylcobalamin is required for the function of the folate-dependent enzyme, methionine synthase. Methionine is essential for the synthesis of S-adenosylmethionine, a methyl group donor required in many biological methylation reactions, including the methylation in DNA and RNA. Symptoms of Methylcobalamin Deficiency: The common cause of vitamin B12 deficiency is a condition known as pernicious anemia and food-bound vitamin B12 malabsorption. Although both causes become more common with increasing age, they are separate conditions. Vitamin B12 deficiency is likely to affect 10% to 15% of individuals over the age of 60. Absorption of vitamin B12 from food requires normal function of the stomach, pancreas, and small intestine. Vegetarians are particularly prone to its deficiency. High dietary sources of methylcobalamin B12 are liver, milk, beef, egg yolk, oysters, salmon & herring.
