Adeno B12 Lozenges by Seeking Health provide 3,000 mcg of adenosylcobalamin, the mitochondrial form of vitamin B12, in an easy-to-deliver lozenge. Adenosylcobalamin is considered an active “coenzyme” form of B12, meaning it is used directly in B12-dependent enzyme reactions in the body. This form provides an alternative to methylcobalamin for individuals who may be sensitive to methyl donors or methylated B vitamins.*

Vitamin B12 is required for proper red blood cell formation, neurological function, and DNA synthesis. Vitamin B12 functions as a cofactor for methionine synthase and L-methylmalonyl-CoA mutase. Methionine synthase catalyzes the conversion of homocysteine to methionine. Methionine is required for the formation of SAMe (S-adenosylmethionine), an important methyl donor.*

Vitamin B12 is naturally present in seafood, shellfish, liver, eggs and dairy products. It may be harder for vegetarians and vegans to meet their daily needs for vitamin B12 from food sources without relying on supplements or fortified foods.*
