Vitamin B12 as Methylcobalamin is a tissue-ready form of vitamin B12. It supports cardiovascular function, normal sleep cycles, blood cell function, and nerve function.*

Many vitamin B12 supplements contain cyanocobalamin as the active ingredient, which the liver must first "detoxify" and modify to form methylcobalamin – an active form of vitamin B12 that is essential for processes involved in cardiac function, sleep, blood cell formation, and nerve function.* Thorne's Vitamin B12, as Methylcobalamin, provides vitamin B12 in its already biologically active and tissue-ready form.* Clinical evidence indicates that the body uses methylcobalamin more efficiently than cyanocobalamin.* Methylcoblamin helps maintain normal circadian rhythms to promote normal sleep and supports healthy methylation processes in the body.*
