What this trial studies

This open-label, direct-to-consumer interventional study asks U.S. adults aged 21–75 to take a ready-to-mix beverage containing protein, fiber, and electrolytes every day for four weeks. Participants complete electronic surveys about symptoms, product use, and acceptability and provide stool and blood biomarker samples at baseline and at the end of the study. The study specifically enrolls people on a stable GLP-1 for at least three months or people trying to lose weight who have not used GLP-1 in the last six months. The aim is to capture participant experience, side effects, self-reported outcomes, and changes in selected biomarkers.

Who should consider this trial

Good fit: U.S. residents aged 21–75 who are willing to take the product daily for four weeks, complete electronic surveys, provide baseline and end-of-study blood and stool samples, and are either on a stable GLP-1 for ≥3 months or trying to lose weight without recent GLP-1 use.

Not a fit: People who are pregnant, breastfeeding, planning to start or stop GLP-1 medications during the study, living outside the U.S., or unwilling/unable to provide samples or a valid U.S. shipping address and mobile phone may not benefit or be eligible.

Why it matters

Potential benefit: If successful, the product could reduce GI symptoms, improve gut-related biomarkers, and support weight-management or wellbeing for some adults.

How similar studies have performed: Previous nutrition trials have shown that protein- and fiber-containing beverages can improve satiety, bowel habits, and some gut biomarkers, but this exact product formulation and direct-to-consumer approach has limited prior testing.
