Hydration Low Sodium Beverage H20

ClinConnect Summary

The Hydration To be Optimized (H2O) trial is studying how a new low-sodium beverage containing whey protein and glycerol affects hydration in healthy adults compared to plain water. Researchers want to see if this special drink helps people stay hydrated better. The study will involve 45 healthy adults who are between 18 and 50 years old. To participate, individuals must have a healthy weight and be free from serious medical conditions that could affect their safety during the trial.

Participants in this study will visit the Clinical Innovation Lab in Lausanne three times. During each visit, they will drink one of the test beverages or plain water and complete some assessments. The study is designed to ensure that participants don’t know which drink they are consuming at each visit, making it a fair test. If you think you might be eligible and are interested in helping researchers learn more about hydration, this could be a great opportunity!
