B Complex Liquid provides all eight B vitamins plus choline. Folate is supplied as methylfolate and B12 as methylcobalamin and adenosylcobalamin, so this is a methylated B complex. B2 and B6 are in their active forms, R5P and P5P. The B vitamins work together to release energy from food. They support the nervous system, psychological function and the formation of red blood cells, and several of them contribute to the reduction of tiredness and fatigue. Each half teaspoon (2.5 ml) provides 10.2 mg of thiamin, 10.4 mg of riboflavin, 25 mg of niacin, 10.7 mg of vitamin B6, 400 mcg of folate, 500 mcg of vitamin B12, 100 mcg of biotin, 25.5 mg of pantothenic acid and 83.3 mg of choline. The liquid form avoids the fillers of a tablet and lets the dose be adjusted. Take half a teaspoon a day, mixed with 200 ml of water, alongside breakfast. A 100 ml bottle holds 40 servings. It is often chosen by people who cannot swallow capsules or who want the active forms of every B vitamin in one measure. It is suitable for vegetarians, free from dairy, gluten and nuts, and made in the UK.
