Opis
Inclusion Criteria:
- Age 18 to 35 years.
- Current UCLA varsity athlete.
- Actively training or competing during the study period.
- Willing to wear WHOOP or a study-approved wearable device continuously during baseline and treatment periods if wearable data are used.
- Willing to take assigned study capsules nightly for 28 days.
- Willing to complete brief daily REDCap surveys and weekly adherence/safety check-ins.
- Able to provide informed consent and comply with study procedures.
Exclusion Criteria:
- Current magnesium supplementation without completion of an appropriate washout before baseline.
- Current investigational drug or investigational supplement use.
- Current use of prescription or over-the-counter sleep medications unless reviewed and permitted by the study clinician.
- Diagnosed sleep disorder that, in the investigator's judgment, would confound outcomes or increase risk.
- Significant kidney disease or another medical condition that may increase risk with magnesium supplementation.
- Known intolerance or allergy to magnesium glycinate, magnesium L-threonate, placebo, or inactive study ingredients.
- Use of medications with clinically relevant magnesium interactions unless reviewed and permitted by the study clinician.
- Any other condition that, in the investigator's judgment, would make participation unsafe, compromise voluntary consent, or prevent valid outcome assessment.

|
|
Eksperymentalny: Magnesium L-Threonate
Participants randomized to this arm will take blinded magnesium L-threonate capsules nightly for 4 weeks.
The current planning target is approximately 2 g/day total magnesium L-threonate, with elemental magnesium content, capsule count, and label language confirmed before activation.
|
Blinded oral magnesium L-threonate capsules taken nightly for 28 days.
|
|
Komparator placebo: Placebo
Participants randomized to this arm will take matching placebo capsules nightly for 4 weeks on the same blinded schedule.
|
Matching placebo capsules taken nightly for 28 days.

Change in WHOOP-derived sleep efficiency percentage from baseline week to final treatment week
Ramy czasowe: Baseline week to final treatment week, approximately 5 weeks total including baseline monitoring
|
Average nightly WHOOP-derived sleep efficiency, expressed as a percentage, will be calculated for the baseline week and final treatment week.
A valid week requires at least 5 usable nights in the 7-day window.
The outcome is final-treatment-week average minus baseline-week average; higher values indicate improved sleep efficiency.
