Does vitamin B6 help PMS?
The evidence is weak. A review of 12 controlled trials found some positive effects, but the trials were too small to be convincing about whether vitamin B6 truly helps PMS.
What they did
The authors searched the medical literature and reviewed 12 controlled trials testing vitamin B6 for PMS, focusing on the quality of each study's methods.
What they found
Some trials showed positive effects of vitamin B6, but the existing evidence is weak. A major problem is that most trials included too few patients.
What it means for you
We cannot yet say whether vitamin B6 truly helps PMS because the studies so far have been too small and the results are not strong enough to be convincing. We would need larger, well-designed trials with clear positive results.
