Summary

This study is testing whether taking a daily supplement called sodium butyrate can reduce menstrual symptoms like pain and bloating. Fifteen women who have regular or irregular periods and rate their symptoms at least 3 out of 10 will take the supplement for 12 weeks and track their symptoms daily. Researchers will compare symptom scores before and during treatment to see if there is improvement.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
sodium butyrate (a dietary supplement)
What this could lead to
If it works, this could point toward a simple, non-hormonal supplement to ease period pain and other menstrual symptoms.
What could go wrong
This is a very small, early-stage trial with only 15 participants and no placebo group, so results may not be reliable or apply to everyone. The supplement may cause digestive upset in some people.
