Summary

This study tested whether a plant-based melatonin supplement (phytomelatonin) from tomatoes can improve sleep quality better than synthetic melatonin or a placebo. 244 adults with poor sleep took one capsule nightly for 28 days. Sleep was tracked with a wearable ring and questionnaires to see which option worked best.

What this could mean

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

Active substance
Phytomelatonin (plant-based melatonin from tomatoes)
What this could lead to
If it works, this could offer a natural alternative to synthetic melatonin for improving sleep quality.
What could go wrong
This is a small, completed study with no phase designation, so results may not be conclusive or generalizable. The plant-based dose is lower than the synthetic one, which could limit effectiveness.
