Descripción
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.

Experimental: Magnesium Glycinate
Participants randomized to this arm will take blinded magnesium glycinate capsules nightly for 4 weeks.
The current planning dose is approximately 240 mg elemental magnesium nightly, with final capsule count and label language based on the selected blinded formulation.
|
Blinded oral magnesium glycinate capsules taken nightly for 28 days.
|
|
Experimental: 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.
|
|
Comparador de placebos: 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.

Periodo de tiempo |
|---|---|---|
|
Change in WHOOP-derived sleep efficiency percentage from baseline week to final treatment week
Periodo de tiempo: 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.

Periodo de tiempo: Baseline to final visit, approximately 5 weeks
|
Reaction performance will be measured using the prespecified BlazePod RIW Challenge protocol.
The outcome is change in reaction time in milliseconds from baseline to final visit.
Lower reaction time indicates better performance.
|
Baseline to final visit, approximately 5 weeks
|
|
Change in BlazePod Speed Tap reaction time in milliseconds from baseline to final visit
Periodo de tiempo: Baseline to final visit, approximately 5 weeks
|
Reaction performance will be measured using the prespecified BlazePod Speed Tap protocol.
The outcome is change in reaction time in milliseconds from baseline to final visit.
Lower reaction time indicates better performance.
|
Baseline to final visit, approximately 5 weeks
|
|
Change in WHOOP-derived sleep consistency score from baseline week to final treatment week
Periodo de tiempo: Baseline week to final treatment week, approximately 5 weeks total including baseline monitoring
|
WHOOP-derived sleep consistency score, or an equivalent prespecified wearable-derived sleep timing regularity metric, will be summarized for the baseline week and final treatment week.
The outcome is final-treatment-week average minus baseline-week average.
|
Baseline week to final treatment week, approximately 5 weeks total including baseline monitoring
|
|
Change in WHOOP-derived total sleep time in minutes from baseline week to final treatment week
Periodo de tiempo: Baseline week to final treatment week, approximately 5 weeks total including baseline monitoring
|
Average nightly total sleep time captured by WHOOP, expressed in minutes, will be calculated for the baseline week and final treatment week.
The outcome is final-treatment-week average minus baseline-week average.
|
Baseline week to final treatment week, approximately 5 weeks total including baseline monitoring
|
|
Change in WHOOP-derived resting heart rate in beats per minute from baseline week to final treatment week
Periodo de tiempo: Baseline week to final treatment week, approximately 5 weeks total including baseline monitoring
|
Nightly resting heart rate captured by WHOOP, expressed in beats per minute, will be summarized as weekly averages for the baseline week and final treatment week.
The outcome is final-treatment-week average minus baseline-week average.
|
Baseline week to final treatment week, approximately 5 weeks total including baseline monitoring
|
|
Change in WHOOP-derived heart rate variability in milliseconds from baseline week to final treatment week
Periodo de tiempo: Baseline week to final treatment week, approximately 5 weeks total including baseline monitoring
|
Nightly heart rate variability captured by WHOOP, expressed in milliseconds, will be summarized as weekly averages for the baseline week and final treatment week.
The outcome is final-treatment-week average minus baseline-week average.
|
Baseline week to final treatment week, approximately 5 weeks total including baseline monitoring
|
|
Change in WHOOP Recovery Score from baseline week to final treatment week
Periodo de tiempo: Baseline week to final treatment week, approximately 5 weeks total including baseline monitoring
|
