maximum dose of vitamin b12 injection 3000 mcg what is the maximum dose

At a glance: RDA: 2.4 mcg/day (adults) UL: Not established (insufficient evidence to set a tolerable upper limit) [ref] Dietary considerations: Vegan and vegetarian diets: Vitamin B12 is only found in animal-based foods, so vegans and vegetarians are often deficient or marginal in their B12 status.[ref] B12 is often added to breakfast cereals and other refined products, so eating a vegetarian diet that includes packaged and refined foods may actually result in higher B12 levels (although probably not in better health)

Common range Community discussions reference 1-2 mg per day SubQ or 1-3% topical formulations
