Methyl B12 (methylcobalamin), a co-enzyme form of vitamin B12, is the principal circulating form of B12 in the body and the form that is active in the central nervous system. Cyanocobalamin, the form of vitamin B12 most often used in supplements, must be converted to methylcobalamin in a lengthy and sometimes inefficient process. Using high dose (1000 mcg or more) methyl B12 supplements spares the body's resources and ensures that adequate amounts of this active form are available to support nerve function, red blood cell formation, energy production, brain function and homocysteine metabolism.Suggested UseOne tablet once or twice daily, or more, as directed by a doctor. Dissolve in mouth under tongue before swallowing.Serving Size: 1 TabletServings Per Container: 60Amount Per ServingVitamin B6 (from pyridoxine HCl)46 mgVitamin B6 (from pyridoxal-5-phosphate)Folate (as folic acid)400 mcgVitamin B12 (as methylcobalamin) (as 1000 mcg methylcobalamin and 100 mcg of cyanocobalamin)1100 mcgOther Ingredients:fructose, sorbitol, isomalt (glucose-sorbitol/glucose-mannitol), natural flavors, dextrose, fructose, xylitol, natural color, stearic acid, magnesium stearate, silicon dioxideWarningsTAMPER EVIDENT BAND AROUND CAP AND SEAL ON BOTTLEDO NOT USE IF EITHER SEAL IS BROKEN OR MISSINGKEEP OUT OF REACH OF CHILDRENCo-Enzyme Form of B12.
