Effects of Magnesium L-Threonate on Sleep, Recovery, and Athletic Performance in Collegiate Athletes
Sponsor: University of California, Los Angeles
Summary
This study is testing whether a special form of magnesium called magnesium L-threonate can help improve sleep quality, recovery, and physical performance in college athletes. Magnesium is important for muscle recovery and sleep, but many forms of it do not enter the brain well. Magnesium L-threonate is unique in that it can cross the blood-brain barrier and may improve deep and REM sleep, heart rate variability, and brain recovery. In this study, healthy UCLA varsity athletes aged 18 to 35 will be randomly assigned to take either magnesium L-threonate or a placebo each evening for 4 weeks. They will wear a WHOOP strap to track sleep, recovery, and heart rate data. Performance tests including jump height, grip strength, and reaction time will be completed before and after the 4-week period. This study will help researchers determine if this supplement can support recovery and training in athletes and whether wearable technology can help monitor these changes in real time.

Interventions
Magnesium L-Threonate
Participants in this arm will take 1 gram of magnesium L-threonate (Magtein), provided in capsule form, once daily in the evening for 4 weeks. This supplement is known for its ability to cross the blood-brain barrier and may enhance sleep architecture, autonomic recovery, and cognitive function.
Placebo
Identical-looking inert capsule taken nightly for 4 weeks. Used as a comparator to magnesium L-threonate to assess changes in sleep, recovery, and performance metrics.
