Methylcobalamin (vitamin B12) is active immediately upon absorption, while other forms (e.g., cyanocobalamin) must be converted to methylcobalamin in a two-step process. Methylcobalamin demonstrates exceptional activity in areas where other forms are simply not active. B12 supplementation is recommended for vegetarians and those with B12 deficiency.
