Brief Summary

Dehydration lowers both physical and mental performance if it is severe enough. Performance declines are more pronounced in hot conditions or after prolonged strenuous activity such as exercise. Most individuals drink less than their sweat losses during activity, while some individuals overdrink and develop a sodium deficiency. Water and electrolyte balance must be restored as part of the recovery process after any activity that causes sweating. Plain water causes a decrease in plasma sodium concentration and osmolality, which reduces the desire to drink and increases urine production. Unless the volume ingested exceeds the loss, individuals are in net negative fluid balance throughout the recovery period due to urinary losses. When sodium and potassium are added to rehydration fluids, urine production is reduced in the hours following rehydration. Rehydration is only possible if a volume of fluid equal to or greater than the amount lost through sweat is consumed, together with adequate electrolytes. The test products for this study, TP1 and TP2, are novel hydration beverage formulas. They are an electrolyte drink mixture with five essential vitamins and three times more electrolytes than typical sports beverages. The test products create an osmotic force that permits water to be supplied to the bloodstream sooner in the digestive system by using a specific ratio of sodium, glucose, and potassium. This randomized, placebo-controlled, semi-blind, crossover study will evaluate the effects of the test products on rehydration in healthy adults.

Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Healthy adult male and female participants who are between 18 and 49 years of age (inclusive).
  • Are in good general health (no active or uncontrolled diseases or conditions) and can ingest the assigned amount of fluid at each visit.
  • Have a body mass index (BMI) between 17.0 and 29.9 kg/m2 (inclusive).
  • Exercise regularly as per physical activity guidelines for Americans \[structured exercise for a minimum of 150 cumulative minutes per week (low end) to 500 cumulative minutes of exercise per week (high-end)\] and willing to maintain the same level of physical activity throughout the study period.
  • Can maintain their exercise status at the beginning of the study throughout the study period.
  • Can achieve a peak VO2 at screening that is at least 60% of their age and gender matched normative value per American College of Sports Medicine recommendations.
  • Have normal or acceptable to to the investigator vital signs (BP and HR) at screening.
  • Individuals with childbearing potential:
  • Agree to practice an acceptable form of birth control for a certain timeframe prior to the first dose of study product and throughout the study, including:
  • use for at least three months prior to the first dose of study product: hormonal contraceptives including oral contraceptives, hormone birth control patch (e.g., Ortho Evra), vaginal contraceptive ring (e.g., NuvaRing), injectable contraceptives (e.g., Depo-Provera, Lunelle), hormonal intrauterine devices (e.g., Mirena), or hormone implant (e.g., Norplant System); or
  • use for at least one month prior to the first dose of study product: double-barrier method, non-hormonal intrauterine devices (i.e., copper), or complete abstinence from sexual intercourse that can result in pregnancy; or
  • vasectomy of partner at least six months prior to the first dose of study product.
  • Individuals with the potential to impregnate others:
  • Agree to use condom or other acceptable methods to prevent pregnancy throughout the study.
  • Complete abstinence from sexual intercourse that can result in pregnancy is also acceptable.
