Summary

This trial aims to investigate how the levels of sodium and glycerol in fluids affect the body's ability to retain water. The study will look at how different amounts of fluid intake impact overall fluid balance

See full description
Who is the study for?
Healthy, active men and women aged 18-50 who don't smoke or take interfering medications can join this trial. They must not be pregnant, avoid alcohol before visits, fast overnight, refrain from vigorous exercise for a day prior, and eat the same food before each lab visit.Check my eligibility
What is being tested?
The study is testing how different electrolyte solutions with varying volumes and concentrations of glycerol affect fluid retention in the body. Participants will try several beverages to see which helps maintain fluid balance best without being lost through urination.See study design
What are the potential side effects?
Since this trial involves common beverage ingredients like sodium and glycerol in healthy individuals at rest, significant side effects are unlikely. However, participants may experience mild gastrointestinal discomfort or changes in urination patterns.
