Summary

This study tests whether a single dose of nicotinamide riboside (NR), a form of vitamin B3, can improve sleep in healthy adults who have mild sleep troubles. Twenty participants will have their sleep measured overnight using advanced monitoring, after taking either NR or a placebo. The goal is to see if NR affects total sleep time and sleep quality.

What this could mean

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

Active substance
Nicotinamide Riboside (NR)
What this could lead to
If it works, this could point toward a natural supplement that improves sleep quality in people with mild sleep difficulties.
What could go wrong
This is a very small, early-stage study in healthy volunteers, so results may not apply to the general public or those with sleep disorders. The effect, if any, may be minimal or not clinically meaningful.
