Primary Outcome Measures

Name	Time	Method
Cohen's Perceived Stress scale	Baseline, Day 7, Day 14, Day 21, Day 28	To determine changes in perceived stress by way of the Cohen's Perceived Stress scale. The minimum is 0 and max is 40, with higher values meaning more stress.
Positive mood and emotion	Baseline, Day 7, Day 14, Day 21, Day 28	Assessed by the Positive and Negative Affect Scale. Min values of 0 and max of 50, higher scores indicate more positive moods and emotions.
Negative mood and emotion	Baseline, Day 7, Day 14, Day 21, Day 28	Assessed by the Positive and Negative Affect Schedule. Min values of 0 and max of 50, higher scores indicate more negative moods and emotions.
Weekly sleep disturbances.	Baseline, Day 7, Day 14, Day 21, Day 28	Assessed by the Patient Reported Outcome Measures of sleep disturbances. Min values of 8 and max values of 40. Higher scores mean more sleep disturbances.
Weekly sleep impairment	Baseline, Day 7, Day 14, Day 21, Day 28	Assessed by the Patient Reported Outcome Measures of sleep impairments. Min values of 8 and max values of 40. Higher scores mean more sleep impairments.
Changes in daily psychological stress	Daily for 4-weeks from baseline to Day 28.	Assessed by the Daily Stress Response Scale. Min 0, max 60 with higher scores indicating higher stress.
Changes in daily physiological stress	Daily for 4-weeks from baseline to Day 28.	Assessed by Daily Stress Response Scale. Min 0, max 60 with higher scores indicating higher stress.
Changes in subjective sleep quality.	Baseline and Day 28.	Assessed by the Pittsburgh Sleep Quality Index questionnaire. Min 0 and max 21, higher scores indicate worse sleep quality.
Changes in objective sleep quality.	Daily for 4-weeks from baseline to Day 28.	Assessed by the Absolute Rest device, higher scores are better.
Changes in sleep efficiency.	Daily for 4-weeks from baseline to Day 28.	Assessed by the Absolute Rest device, total time asleep divided by time in bed, expressed as a percentage, higher is better.
Changes in sleep latency	Daily for 4-weeks from baseline to Day 28.	Assessed by the Absolute Rest device, time taken to fall asleep.
Changes in sleep duration	Daily for 4-weeks from baseline to Day 28.	Assessed by the Absolute Rest device, total sleep time.
Changes in sleep apnea	Daily for 4-weeks from baseline to Day 28.	Assessed by the Absolute Rest device, values measures by oxygen saturation.

Secondary Outcome Measures

Name	Time	Method
Percent compliance of supplement use	End of Week 2 and Week 3.	To determine the percent of compliance when taking AM and PM pills. Will be measured by the amount of pills taken / pills prescribed multiplied by 100.
