Types of vitamin B12 supplement

B12 is sold in several forms. Methylcobalamin is the most common in this range, alongside adenosylcobalamin, hydroxocobalamin and cyanocobalamin. Strengths range from around 100mcg in daily sprays to 5000mcg in high-strength lozenges. Some products pair B12 with folic acid or methylfolate.

Tablet, spray or drops?

Fast-dissolve tablets and lozenges are taken under the tongue, sprays are used in the mouth and drops can be added to a drink. Choose the format that is easiest for you to take every day.
