Summary
This study tests whether taking magnesium L-threonate for six weeks improves sleep quality, mental focus during fatigue, and muscle function in healthy adults aged 18 to 45. Participants receive either the supplement or a placebo, and researchers measure sleep scores, reaction times, and jump height. The trial also looks at whether effects differ by sex or weight.
