The presence of certain ingredients such as sodium and glycerol can facilitate retention of the fluid consumed via renal water reabsorption. To maintain overall whole-body fluid balance, it is important that ingested fluid is retained in the body instead of losing it through urination.
The purpose of this study is to determine the effect of sodium and glycerol concentrations at various fluid intake volumes on fluid balance in healthy, euhydrated men and women.
