Life Extension Vitamin B12 Methylcobalamin, Nerve Health Supplement, Cognitive Support, Energy Vitamin, methylcobalamin B12, 1 mg, Quick-Dissolving, Vegetarian, 60 lozenges

Vitamin B12 is present in foods of animal origin, including dairy products and eggs. Thus, vegetarians are more susceptible to a dietary deficiency of this important nutrient. Likewise, vitamin B12 serum concentrations are reported to be significantly lower in elderly population groups compared to younger groups. It is estimated that 10% to 30% of individuals over the age of 50 have low stomach acid secretion which results in decreased bioavailability of vitamin B12 from food. Methylcobalamin is the form of vitamin B12 active in the central nervous system. It is essential for cell growth and replication. In some people the liver may not convert cyanocobalamin, the common supplemental form of vitamin B12, into adequate amounts of methylcobalamin needed for proper neuronal functioning. Methylcobalamin may exert its neuroprotective effects through enhanced methylation, acceleration of nerve cell growth, or its ability to maintain already healthy homocysteine levels.
