Methylcobalamin is the active, coenzyme form of vitamin B12. Cyanocobalamin, the most common form of supplemental B12, must be converted first into hydroxocobalamin, and then into adenosylcobalamin, which is finally converted into methylcobalamin. Since cyanocobalamin must undergo this extensive conversion process, supplementation with methylcobalamin is preferable, and it is also the specific form of B12 shown to support the brain and nervous system.AOR’s Methyl B12 – 5 mg provides 5 mg in an easy to take lozenge making it ideal for those who have neurological conditions or nerve problems. Vegetarians, elderly people, those suffering from pernicious or megaloblastic anemia, atrophic gastritis, Celiac disease, Crohn’s disease or other types of inflammatory gastrointestinal disorders are at greater risk for B12 deficiency and may benefit from high doses of methylcobalamin.AOR AdvantageWhile the RDA (Recommended Dietary Allowance) for vitamin B12 in Canada is just 2.4 micrograms and the upper limit is just 1 milligram, AOR’s Methyl B12 – 5 mg provides a high, clinically effective dosage of the most bioavailable form of vitamin B12 in a convenient and pleasant-tasting lozenge form.
