Getting Started
To get started, complete the initial screening survey, which can be found here. A researcher will review your health history to ensure the study is a good fit for you.
If you are invited to participate, you will receive a link to schedule a 10-15 minute orientation meeting with a member of our team. During this time we will answer any questions you may have. Afterwards, we will ship your materials to you.
During the Study
When your materials arrive, you will visit the link included in your kit to activate the kit and get started.
Every evening during the 28-day study, you will take the supplement just before bed and sleep at night wearing your Apple watch. On days 7, 14, 21, and 28, you will take a 5-10 minute online survey. That's it!
Your Benefits
We will send you up to $120 for participating. You will also receive your 4-week supply of a sleep supplement for free. (There are no placebos in this study; everyone receives a supplement.)
During the study, our team is available to you 24/7.
Interested in the results? Once the study is complete, a private zoom invitation will be sent to all study participants with an overview of the findings!
