# Can vitamin B6 supplements treat health conditions beyond nutritional deficiency?

Many conditions have been treated with B6, but there is little evidence from controlled trials that it actually works for them.

 Early or limited evidence

Not specified; this is a review of general research

## What they did

This was a review of research on how vitamin B6 is used to treat various health conditions. The authors examined both the theoretical reasons B6 might help and the actual evidence from controlled trials.

## What they found

B6 has been used to treat many different conditions. Some uses are based on theory about how B6 works; others were discovered by trial and error. However, there is little evidence from properly conducted controlled trials that B6 actually works for these uses. At very high intake levels, B6 can damage peripheral nerves.

## What it means for you

Although B6 is often used to treat many conditions, we don't have good research proof that it works. The main limit is that this is a review of existing evidence, not a new study, and it shows the evidence is weak.
