Best Vitamin B12 3000 Mcg Too Much

Vitamin B12 is a member of the B-complex family of water-soluble vitamins. Vitamin B12 has numerous functions in the body including, stimulating red blood cell production, support of healthy nerve function and the metabolism of homocysteine.* Low levels of vitamin B12 are often seen in vegetarians, as plant foods lack vitamin B12, and also in elderly people as their ability to absorb B12 from food is limited. The absorption of B12 requires a protein called intrinsic factor which is secreted by cells in the stomach. Elderly people secrete less intrinsic factor and therefore absorb less vitamin B12. Consuming a sublingual B12 lozenge helps avoid any problems with absorption as it is dissolved in the mouth, and the B12 is absorbed directly into the bloodstream. This helps provide significant amounts of B12 without concern for GI absorption. The synergistic nutrients folate, B6 and biotin are provided for added support.

Methylcobalamin (Methyl B-12) is better absorbed and retained than other forms of B12 (e.g., cyanocobalamin).* Methyl B-12 supports nerve tissue and brain cells, promotes better sleep and converts (via methylation) homocysteine, an oxidizing metabolite, back into the amino acid methionine.* Also, vegetarians/vegans often require B12 supplementation.*
