NIH B12 Overview
Vitamin B12 Adenosylcobalamin

Adenosylcobalamin is the second active coenzyme form of Vitamin B12. It is stored in the mitochondria, where it drives energy production by supporting fatty acid and amino acid metabolism.
Vitamin B12 must be converted into its active forms—methylcobalamin and adenosylcobalamin—in order to be utilized by the body. However, certain genetic variations, such as MTR or MTRR mutations, can reduce this conversion efficiency. Synthetic forms like cyanocobalamin, commonly found in some supplements, may not fully convert to the active forms. By using methylcobalamin in our formulation, we provide a bioavailable form of B12 that is ready to support brain, nerve, and heart health.*
Includes both adenosylcobalamin and methylcobalamin for complete B12 coverage. Supports both neurological function and direct mitochondrial energy. Formulated to mimic how B12 works naturally in the body.*
Animal products (liver, fish, dairy) Rarely found in standard supplements, which often exclude this active form
Did You Know?
Without B12, the human body would cease to produce energy at the cellular level. If left untreated, this would eventually lead to cellular death.
