Methylcobalamin (an active form of vitamin B12) is essential for recycling homocysteine and the formation of methyl donors involved in cardiovascular function, sleep, blood cell formation, and nerve function. Most vitamin B12 supplements contain cyanocobalamin; however, the liver must first "detoxify" the cyanide molecule and attach a methyl group to form methylcobalamin from the cyanocobalamin. Methylcobalamin is already in the biologically active, tissue-ready form. Evidence indicates the body utilizes methylcobalamin more efficiently than it does cyanocobalamin. Research shows the quantity of cobalamin detected following a small oral dose of methylcobalamin is similar to the amount following administration of cyanocobalamin; but significantly more cobalamin accumulates in liver tissue following administration of methylcobalamin. Human urinary excretion of methylcobalamin is about one-third that of a similar dose of cyanocobalamin, indicating substantially greater tissue retention.

This is the only B12 you need! Stay away from the poison, called cyancoballamin.

Thorne Research Methylcobalamin

Posted by Reviewer2414050 on Aug 15, 2011

I take this in conjunction with L-Methylfolate and although I have MTHFR Deficiency w/tetrahydrobiopterin Deficiency and mastocytic enterocolitis, there's no doubt I'm absorbing it. It makes a big difference in my mobility, pain levels and muscle tension (-).

"Methylcobalamin" form of B12 is the "natural" form to be taken...not "Cyanacobalamin"....Thorne has a great reputation for purity..great price here!
