What are the steps? 

Getting Started

Want to join the study? Complete the form below. You'll receive an email with a link to provide more information about your health status. This allows our researchers to determine whether you are a good fit for this study. 

Please allow 2-4 days for our team to review your information. If this study is a good fit, you will receive a link to schedule your on-site visit with one of our researchers in Franklin TN, Atlanta GA, OR Huntsville AL. These meetings will last 15-25 minutes minutes. During this time, our team will give you instructions for participating, and will make sure all of your questions are answered. You will also receive your 13 week supply of materials during this visit. 


Get Going!

Once you finish your on-site visit, you'll begin taking 2 capsules each day, one in the morning and one at night.  

Each evening, our team will text you to ask if you had any symptoms of illness that day (respiratory, gastrointestinal, dermal, or other). If you did not, simply text "no," and you are finished for the day. If you did, respond "yes" and you will be taken to a 2-4 minute survey about that day's symptoms. 

Our team will also check in on days 30 and 60 to make sure everything is going according to plan. You will also take a 25-30 minute survey on the first day and at the end of the 13-weeks, whether or not you had any sick days during the study. 


Payment & Support

You will enjoy 24/7 access to a member of our research team during the study. You can reach out at any time with questions. We will also reach out to you regularly to ensure everything is going well. 

You will receive $120 for completing the entire study. Compensation is sent within 1 week of each benchmark you hit. You will receive an email voucher which can be redeemed online within 6 months for a Visa cash card or a gift card at one of over 100 retailers.

After the study is complete, you will be invited to attend a private zoom webinar with other study participants where an overview of the findings will be released.
