Can a 'super-whey' shake help seniors build stronger muscles?
NCT ID NCT05700058
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how a new type of whey protein, called 'super-whey,' affects muscle building in older adults. Researchers will test three different doses to see which one works best, both at rest and after exercise. The goal is to find a low-dose protein option that helps maintain muscle health without making people feel too full. The study involves 30 healthy older adults (65+ years) and uses muscle biopsies and blood tests to measure results.
