Summary

This small study tested a dietary supplement called NatureU Sweet Dream, which contains GABA and Lactium, against a standard melatonin product in 17 adults with mild to moderate sleep problems. Participants wore a sleep tracker to measure deep sleep duration and percentage. No side effects were reported, but the study was very small and not blinded, so the results are preliminary.

What this could mean

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

Active substance
NatureU Sweet Dream (GABA and Lactium dietary supplement)
What this could lead to
If it works, this could point toward a natural supplement option for improving deep sleep without the side effects of melatonin.
What could go wrong
This was a very small (17 participants), open-label, exploratory study with no blinding, so results may not be reliable or generalizable. The supplement is not a drug and has not been rigorously tested.
