evidence for vitamin b complex

Our honest take

A high-potency B complex in a vegan capsule, using active forms such as P-5-P and methylcobalamin: 25 mg of B1, 30 mg of B2, 100 mg of B5, 250 µg of B12 and 25 mg of vitamin B6. That B6 dose is two and a half times the FSA's advice of no more than 10 mg a day long term, and Cytoplan's own label warns that long-term use may cause tingling and numbness. These doses bring no proven extra benefit if you are not short of B vitamins; Cytoplan's gentler Multi B Extra is the better everyday choice.

  • You eat a restricted diet and want all the B vitamins in active forms
  • You prefer a UK practitioner brand and have checked the label doses
  • You eat a varied diet: you probably get enough B vitamins already
  • You already take a multivitamin or a magnesium or zinc product with B6: add up your total B6 first
  • You want value: a moderate-dose B complex costs a fraction of the price
The science

Vitamin B complex· evidence: Limited

A B complex combines the eight B vitamins: thiamin (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), B6, biotin, folate and B12. Together they help the body release energy from food and keep the nervous system and blood healthy. Most people who eat a varied diet get enough of all of them, and B vitamins have not been shown to give extra energy to people who are not short of them.

A B complex can make sense for people with restricted diets, older adults who eat little, heavy drinkers, or vegans who want B12 covered. Vegans mainly need B12, which a single B12 product covers more cheaply.

Products vary a lot. "B-50" and "B-100" formulas give 25 to 100 times the daily need of some B vitamins, which brings no proven extra benefit and can push vitamin B6 well above the UK's 10 mg safety advice. Bright yellow urine is harmless and comes from riboflavin.

Authorised health claim
Claims only apply to a B vitamin that a daily dose provides at 15% of its NRV or more. Common authorised claims include:

Thiamine contributes to normal energy-yielding metabolism.
Riboflavin contributes to the reduction of tiredness and fatigue.
Niacin contributes to normal psychological function.
Pantothenic acid contributes to normal mental performance.
Vitamin B6 contributes to the regulation of hormonal activity.
Folate contributes to normal blood formation.
Vitamin B12 contributes to normal red blood cell formation.
Biotin contributes to the maintenance of normal hair.

Typical dose: Around 100% of the NRV of each B vitamin covers daily needs. Many products give far more; there is no proven benefit to higher doses for people who are not deficient.

Safety: Check the vitamin B6 content: the Food Standards Agency advises no more than 10 mg a day from supplements long term, because higher doses can damage nerves. Nicotinic acid (a form of B3) can cause flushing. More than 1 mg of folic acid a day can hide B12 deficiency. High-dose biotin can distort some blood test results (including thyroid and heart tests), so tell your doctor you take it.

Vitamin B6· evidence: Limited

Vitamin B6 (pyridoxine, or the active form pyridoxal-5-phosphate, P-5-P) helps the body use protein and make red blood cells and some brain chemicals. Adults need only about 1.2 to 1.4 mg a day, and most people in the UK get this easily from meat, fish, wholegrains, potatoes, bananas and fortified cereals. True deficiency is uncommon.

For people who are not deficient, there is little good evidence that extra B6 does anything useful. It is often combined with magnesium or zinc in sports products; the B6 in these is mostly there to carry the label claims.

The bigger issue with B6 is safety. Long-term high doses can damage the nerves in the hands and feet, and this has been reported at doses sold freely in shops.

Authorised health claim
Vitamin B6 contributes to normal cysteine synthesis. Vitamin B6 contributes to normal energy-yielding metabolism. Vitamin B6 contributes to normal functioning of the nervous system. Vitamin B6 contributes to normal homocysteine metabolism. Vitamin B6 contributes to normal protein and glycogen metabolism. Vitamin B6 contributes to normal psychological function. Vitamin B6 contributes to normal red blood cell formation. Vitamin B6 contributes to the normal function of the immune system. Vitamin B6 contributes to the reduction of tiredness and fatigue. Vitamin B6 contributes to the regulation of hormonal activity. (Applies where a daily dose gives at least 15% of the NRV, i.e. 0.21 mg.)

Typical dose: Adults need about 1.2 mg (women) to 1.4 mg (men) a day (NRV on labels: 1.4 mg). A supplement giving 1.4 to 10 mg is plenty.

Safety: The Food Standards Agency advises not taking more than 10 mg of vitamin B6 a day from supplements unless a doctor advises it. Taking more than this for a long time can cause loss of feeling in the arms and legs (peripheral neuropathy). Add up the B6 from all your supplements, including B complexes, magnesium/zinc products and multivitamins. Stop and see your GP if you notice tingling, numbness or burning in your hands or feet.
