Vitamin B12: a simple buying guide

Vitamin B12 supplements in tablets, sublingual lozenges, oral sprays, liquid drops, capsules and gummies. The range includes the main forms you will see on labels: cyanocobalamin, methylcobalamin, adenosylcobalamin and hydroxocobalamin, plus combinations with folate or methylfolate.

Vitamin B12 contributes to the reduction of tiredness and fatigue, to normal red blood cell formation and to normal energy-yielding metabolism. Vitamin B12 is found naturally in animal foods, which is why vegans often look for a supplement or fortified foods. Strengths range from everyday doses to high-strength 1000 mcg products, so compare micrograms per serving. Sprays and drops suit people who prefer not to swallow tablets, while lozenges dissolve in the mouth. Brands include NOW Foods, Jarrow Formulas, Osavi, Life Extension, Doctor's Best, Cytoplan and BetterYou. Our vitamin B12 guide explains the forms.
