Impact of Nuun Instant on Hydration Status in Active Men and Women

Plain-language summary

While Nuun Instant is commercially available and has received positive reviews from athletes, there have been no studies to date to evaluate the impact of this product on hydration status. Therefore, the purpose of this study is to determine the impact of Nuun Instant powder and new product under development called Nuun Electrolyte on hydration status in young and active men and women. We will follow a similar approach as used by Maughan and colleagues (2016) to measure the fluid balance (the difference between the amount of water consumed and passed as urine) and beverage hydration index (the relative amount of urine passed after consumption of a drink compared to water), while also measuring plasma volume using the method of Dill and Costill (1974).
