About this trial

Glycerol and sodium are osmotically-active ingredients that promote fluid retention via renal water reabsorption. The purpose of this study is to compare the effects of a glycerol-electrolyte beverage on fluid balance in healthy euhydrated men and women

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Subject is male or female

If female, subject is not pregnant

Subject is 18-50 years of age, inclusive

Subject is at least recreationally active (engaged in light to moderate intensity, intermittent, or steady-state exercise at least 3 days per week for at least 30 min at a time)

Disqualifiers

Subject has participated in a clinical trial within the past 30 days

Subject has participated in any PepsiCo trial within past 3 months

Subject has a condition or is taking medication that the investigator believes would interfere with his/her ability to provide informed consent, comply with the study protocol, which might confound the interpretation of the study results, or put the person at undue risk

Subject is employed by, or has a parent, guardian, or other immediate family member employed by a company that manufactures any products that compete with any Gatorade product. If subject is unsure if a company would be considered a competitor to Gatorade, they will be asked to please let the study investigator know the name of the other company and the nature of their relationship to that company before they sign the informed consent.
