Methylcobalamin is a more predominant and active form of Vitamin B-12. Regular Vitamin B-12 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. B-12 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 B-12 promotes heart health and energy metabolism. Our vegetarian-friendly microlozenges supply you with a high-potency source of B-12.
