Vitamin B12 Methylcobalamin: price per 1 mg

We count the amount of cobalamin stated on the label, converting between units (for example micrograms and IU) so every product is on the same scale.

Prices last checked: 17 September 2026. Ranked purely by price per 1 mg — a comparison unit, not a recommendation. We may earn commission from these links; it never affects the order.
