Product Description

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.
