Probiotics for Anxiety

About the Study

People Science is conducting a new type of study to understand the effectiveness of a probiotic containing Lactiplantibacillus plantarum on anxiety. In this study, we aim to collect data related to your anxiety, sleep, mood, cognition and quality of life before and after taking the probiotic. All study activities can be done from the comfort of your home. The results of this study will allow you and the researchers to understand if this new probiotic can be used to help improve anxiety. 

After signing up, you will take a short online survey to find out whether you qualify for the study. After qualification, you will be able to review the consent form and decide if you’d like to continue with participation. After consent, you will complete brief surveys about your medical and social history and current medications you take using your smartphone. You will also answer daily online surveys before and during the study. You will also be asked to use a wrist-worn device that tracks your sleep. The data you provide will be made anonymous, and the analyzed results will be shared with you and the research scientists.
