NCT ID NCT07756164
First seen Aug 10, 2026 · Last updated Aug 11, 2026 · Updated 1 time
Summary
This trial tests whether a magnesium-based supplement taken before bed can improve sleep quality and speed up recovery after intense exercise. Healthy, recreationally active adults aged 18-40 will take the supplement or a placebo for two weeks each, then complete a leg exercise protocol designed to cause muscle soreness. Researchers will measure muscle performance, soreness, and sleep quality to see if the supplement makes a difference.
