Natural Factors, B12 Methylcobalamin 1,000 Mcg, 90 Chewables

Biologically Active Form of B12

Support For Nerve Function, Energy Production & Red Blood Cells

The methylcobalamin form, absorbed sublingually (under the tongue), is the most active form of vitamin B12 and is shown to have advantages over cyanocobalamin and all other forms of B12, including injections. It absorbs as readily, but keeps blood levels high. Injections provide a B12 surge, followed by a drop to a plateau level. Methylcobalamin is active immediately upon absorption as compared to cyanocobalamin that must first be converted to methylcobalamin by the body. B12 supplementation is recommended for vegetarians and those suffering from B12 deficiency.

All Natural Factors products are manufactured in accordance with the Government of Canada's Good Manufacturing Practices (GMP), among the highest standards in the world.
