B12
500 mcg, 100 lozenges
Item Catalog Number:
00361

Vitamin B12 is provided in foods of animal origin, including dairy products and eggs thus, making vegetarians more susceptible to a dietary deficiency.225 Likewise, vitamin B12 serum concentrations are reported to be significantly lower in elderly population groups compared to younger groups.211-216 It is estimated that 10% to 30% of individuals over the age of 50 have low stomach acid secretion. Therefore they have decreased bioavailability of vitamin B12 from food.210,211,217,218 To overcome food-bound vitamin B12 malabsorption problems, the Institute of Medicine recommends that vitamin B12 fortified foods (such as fortified ready-to-eat breakfast cereals) or supplements containing vitamin B12 be used to meet much of the requirement.210,211 Vitamin B12, or cobalamin, works synergistically with the B vitamin folate to regenerate (methylate) the amino acid methionine, which helps to maintain already healthy homocysteine levels within normal range, which is important for heart health.219,226*

Cyanocobalamin is a synthetic and inexpensive form of vitamin B12 that is easily converted in the body to its bio-active forms, methylcobalamin, and cobamamide.
