Comparing vitamin B12

Labels give cobalamin in micrograms, and some in milligrams: 1 mg is 1,000 mcg. We put every product in one unit before pricing it. Vitamin B12 comes as methylcobalamin, cyanocobalamin, hydroxocobalamin and form not stated, and each form has its own table, because someone buying one would not usually take another as a like-for-like substitute. A product with one other ingredient is ranked here with an “also contains” note; products that combine vitamin B12 with several others are listed separately, because their price buys more than cobalamin. 1 mg is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

Most prices last checked: ; an older price shows its own date. Ranked purely by price per 1 mg — a comparison unit, not a recommendation. We earn commission when you buy through these links; it never affects the order.

4 of the 10 cheapest links on this page earn us nothing; the order is price alone. Shop by shop
