All trials for Hydration All trials of Hydramin hydration solution All trials of Carbohydrate and Electrolyte hydration solution
In this study, the impact of two electrolyte hydration stick products (Hydramin containing an electrolyte/amino acid formulation and an identical electrolyte product with the amino-acids replaced with carbohydrate, dextrose) dissolved in 1 liter of water will be assessed and compared to a control (1 liter Smart Water). It is hypothesized that the addition of amino acids and glycine should improve the Beverage Hydration Index above water alone and perform comparably to the carbohydrate rich solution.
This study will focus on general population (not athletes) and follow very similar approaches used in previous studies within the Center for Nutraceutical and Dietary Supplements Research, with the addition of blood glucose testing and body water measurements. Hydration will be assessed via fluid balance (the difference between the amount of water consumed and passed as urine) and calculations of beverage hydration index (the relative amount of urine passed after consumption of a drink compared to water)as well as time in positive fluid balance, and specific gravity, and sodium and potassium in urine. Blood glucose before and following consumption using finger pricks and a glucometer will also be assessed.

| Hydramin, Electrolyte and Carbohydrate, Water | Experimental | Dietary Supplement: Hydramin hydration solution; Dietary Supplement: Carbohydrate and Electrolyte hydration solution; Dietary Supplement: Water | At the beginning of each visit, subjects will arrive hydrated having consumed the standardized meal replacements the day before. Baseline measures will be taken and the subject will then consume one fourth of the randomly assigned condition provided to them every 7.5 minutes (1 liter total volume) over a 30-minute period. After the 1 liter is consumed, subjects will then be monitored for an additional four hours. Visit 1: Hydramin solution Visit 2: Electrolyte and Carbohydrate Visit 3: Water |
