High-protein drink for muscle loss during cancer treatment
This study tests whether a high-protein drink can help prevent or improve muscle loss and weakness in people with cancer who are getting chemotherapy or preparing for chest surgery. If you are 40 or older, have low muscle strength, and can manage daily activities, you may be able to join.
Taipei, TaipeiAges 40 years+ - NCT06781619Recruiting
Plant-based drink study for people at risk of malnutrition
This study tests a plant-based, high-energy, high-protein drink for people who are at medium or high risk of malnutrition. You would replace your current prescribed supplement with either a plant-based or dairy-based drink for 8 weeks to see how it affects your nutrition.

Test supplements to change how sugars attach to blood proteins
This early (Phase 1) study tests how adding specific dietary supplements affects “protein glycosylation,” which means how sugar molecules attach to proteins in your blood. It’s meant to see how the supplements change these blood measurements and whether the approach is tolerable in generally healthy adults.
Sacramento, CaliforniaAges 18–45 - NCT06673082Enrolling by invitation

Testing a muscle stimulation and extra protein plan in ICU patients
This trial tests whether electrical muscle stimulation plus extra protein (protein substitute) can improve muscle health and metabolism in critically ill adults in the ICU. If you’re newly admitted and expected to stay on a breathing machine for several days, it may help you keep more muscle strength during recovery.

Common questions
- Are there clinical trials for protein supplementation?
- Yes. Clin2 currently lists 51 recruiting protein supplementation studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a protein supplementation trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a protein supplementation trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
