Effect of Gum Acacia and Electrolytes on Hydration After an Exercise-indued Dehydration (NEX/008624)
A Single-blinded, Placebo-controlled, Three-way Crossover Pilot Study, to Assess the Rehydrating Effect of a Nutritional Preparation Containing Gum Acacia Combined With Sea Magnesium After Exercise-induced Dehydration
This clinical study is a single-blind, placebo-controlled, three-way cross-over trial evaluating the rehydration efficacy of two nutritional beverages compared to water, after one administration. The investigational products are gum acacia alone, and combined with sea electrolytes as magnesium. Participants, physically active men undergo exercise-induced dehydration followed by controlled rehydration procedure with each product in randomized sequence. The study includes standardized preconditions (diet, hydration, activity control), exercise and rehydration protocols.
Gam acacia has the benefit of few preclinic studies in murin models showing significant improvements on electrolytes and water absorption, but its effect on hydration in human has never been evaluated.
The combination with sea electrolytes has been developed to optimise and reduce the total concentration of electrolytes into the beverage compared to standard formulations proposed for rehydration in sport application.
