Methylcobalamin is a more predominant and active form of Vitamin B12. Regular Vitamin B12 supplements must be converted in the body to Methylcobalamin before they can provide any benefits taking Methylcobalamin allows you to bypass this step for quicker absorption. B12 may not be as readily absorbable as you age, so older adults may especially benefit from taking a Methylcobalamin supplement. This biologically active form of B12 promotes heart health and energy metabolism. Our vegetarianfriendly microlozenges supply you with a highpotency source of B12.
