This is a fully remote study looking at how healthy adults perceive their hydration, sleep quality, and relaxation while using a daily electrolyte and wellness powder, compared with a placebo. Your participation helps build real-world evidence about how people actually experience this product, which can support future product claims for the study sponsor.

About This Study

Fully Remote Participation

Blood Draw at Home
A single finger-prick collection at Day 28 checks sodium, potassium, creatinine, and kidney function. You mail your sample back in a prepaid envelope to a certified lab.
Milestone-based Compensation
Get paid in milestones as you complete study tasks: $10 at Week 1, $10 at Week 2, $10 at Week 3, and $20 at Day 28, issued as an electronic gift card within two weeks of each milestone.
Your Data Returned
At the end of the study, you'll receive a summary of the group's findings plus your own individual report built from your weekly photos and at-home test results.

What's Involved

Each week, you'll complete short surveys on hydration, sleep, and relaxation through the Alethios app, three days a week you will test your urine with a provided reagent strip, and once a weeksubmit a facial photo. At Day 28, you'll complete final surveys and photos and mail in one at-home finger-prick blood spot sample using a prepaid envelope. There are no clinic visits: everything happens from home.

Screen Into the Study and Complete Electronic Consent

Complete Onboarding and Baseline Assessments

After you're randomized and your kit arrives, complete baseline surveys on hydration, sleep, and relaxation through the Alethios app, confirm receipt of your study product, urine test strips, and blood spot kit, and submit your first urine strip photo and facial photo before taking your first dose.

Complete Weekly Surveys and At-Home Testing

For three weeks, take your assigned product daily, complete weekly surveys on hydration, sleep, and relaxation through the Alethios app, test your urine with a reagent strip and photograph it three mornings a week, and submit a weekly facial photo.

Wrap Up Final Assessments and Receive Compensation

At Day 28, complete your final surveys, submit your last urine strip photo and facial photo, and mail in your at-home blood spot collection using the prepaid envelope. You'll receive $10 at Week 1, $10 at Week 2, $10 at Week 3, and $20 at Day 28, paid as an Amazon gift card within two weeks of each milestone.

What's Being Studied?

Hydration is one of the most common everyday wellness concerns, and many people choose supplements based on how a product makes them feel rather than on lab measurements alone. What's less well understood is whether a daily electrolyte and wellness powder changes how people experience their own hydration, sleep, and relaxation compared with a placebo, and whether that experience differs by dose. This study tracks perceived hydration, sleep quality, and relaxation through weekly surveys over four weeks of product use, along with exploratory urine and skin measurements and a Day 28 blood spot safety panel.
