80% of Vitamin B12 in plasma is in the methylcobalamin form. Methylcobalamin is the active form of B12. Chewable B-12 MC is absorbed through the mouth thus by-passing the need for the intrinsic factor in the stomach. This is especially important for the elderly as the intrinsic factor declines with age. B12 also benefits vegetarians who are often deficient due to dietary inadequacy.*
