Product Overview


  • Biologically Active Form of B12
  • Support for Nerve Function, Energy Production & Red Blood Cells

Natural Factors Methylcobalamin is active immediately upon absorption, while other forms (e.g., cyanocobalamin) must be converted to methylcobalamin in a two-step process. Methylcobalamin demonstrates exceptional activity in areas where other forms are simply not active. B12 supplementation is recommended for vegetarians and those suffering from B12 deficiency.

scored to break evenly in half

Posted by KentuckyWildcat on Jun 07, 2016

In addition to dissolving quickly and tasting good, these little tablets are scored for breaking in half easily by hand. I trust Natural Factors and their GMP to create high quality products.

My husband used it, in the past, for a period of time and it worked combined with b12 and diet based in greens especially broccoli. Now we have reordered it, it's taste is like medicine, also wish it had no magnesium stearate and lactose, else I hope it will work.

Great product

Posted by Reviewer2158129 on Feb 15, 2015

Give this to my 89 year old mother who has B-12 deficiency. Methylcobalamin is the choice in B-12 supplements. Gives her lots of energy and helps a great deal with memory and clear thinking. Very satisfied with product. Also like that there are no artificial sweeteners in it.
