B Complex

52 B complex products in capsules, tablets and liquids, including standard, high-strength, methylated and food-state formulas. Brands include Viridian, Solgar, Quest, Biocare, Natures Aid and HealthAid.

What is in a B complex?

Eight vitamins: thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), B6, biotin (B7), folate (B9) and B12. They occur together in food, which is the usual argument for taking them together rather than singly.

What do they do?

All eight contribute to normal energy-yielding metabolism. Riboflavin, niacin, pantothenic acid, B6, B12 and folate contribute to a reduction of tiredness and fatigue. Thiamine, niacin, biotin, B6 and B12 contribute to normal psychological function and to the normal functioning of the nervous system. B12 and folate contribute to normal red blood cell formation, and folate contributes to maternal tissue growth during pregnancy.

Methylated forms

Some products supply folate as methylfolate and B12 as methylcobalamin rather than folic acid and cyanocobalamin. These are the forms the body uses directly. Biocare's Methyl B Complex and Viridian's High Twelve are the ones customers most often ask for by name.

B12 and vegan diets

B12 is found almost exclusively in animal foods, so a reliable source is needed on a vegan diet - either fortified foods or a supplement. It is the single most important supplement for anyone eating entirely plant-based. See our B12 range if you only need that one.

Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.
