First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested two versions of a low-sodium drink containing whey protein and glycerol to see if they help the body hold onto more fluid than plain water. Forty-three healthy adults took part in a crossover trial where each person tried both drinks and water on separate days. Researchers measured how much fluid the body retained after two hours.
