Active Vitamin B12: Methylcobalamin
Like cyanocobalamin, Methylcobalamin is a form of vitamin B12. The big difference, however, is that this methyl form is the active form as it is needed by the body. It no longer needs to be activated and and its presence in the body stays longer. This form is also better stored by the body. Oral administration of this form of vitamin B12 is the most effective way for a high vitamin B12 intake.
Vitamin B12 is necessary for normal red blood cell formation, tissue and cellular repair and DNA synthesis.
Best form of Vitamin B12
Thorne's Vitamin B12 provides 1000 mcg of methylcobalamin. Careful use has been made of only the most available form that the body doesn't have to convert itself.
