Product Overview


  • Essential B Vitamin
  • Dietary Supplement
  • Non-GMO

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. 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. Vitamin B12, or cobalamin, works synergistically with vitamin B6 and 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.

Read the entire label and follow the direction carefully prior to use.

Wrong labelling from cyanocobalamin to methylcobalamin

Posted by iHerb Customer on Sep 27, 2017 | Verified Purchase

Pls be aware that as of the writing of this review, 27th Sept 2017, I just received this product, but it says methylcobalamin instead of cyanocobalamin.

Thanks for your feedback!
