evidence for vitamin b6

Our honest take

A single-ingredient vitamin B6 capsule from a US brand. US B6 products are commonly 50 to 250 mg per capsule, many times the 10 mg a day the Food Standards Agency advises as the long-term limit from supplements, and long-term high doses can damage the nerves in the hands and feet. Adults need only about 1.4 mg a day and most get it from food. We could not verify this product's dose, so check the label carefully before buying.

A doctor has advised you to take vitamin B6 on its own, at a set dose and for a set time
You have not been advised to take B6: most people get enough from food
You already take a B complex, multivitamin or magnesium/zinc product with B6
You have tingling, numbness or burning in your hands or feet, or take levodopa, phenytoin or phenobarbital

The science

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.

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.
