A new clinical study has found that Trace Minerals' ZeroLyte hydrates two times faster than water following exercise-induced dehydration.
These findings make it the first clinically studied sugar-free electrolyte shown to do so.
The research was conducted by the Hydration Science Lab at Arizona State University (ASU), with findings to be presented at the American College of Sports Medicine (ACSM) Annual Meeting, May 26-29, 2026.
It enrolled both male and female participants who underwent an exercise-dehydration protocol before rehydrating with either ZeroLyte or plain water.
Researchers measured body weight restoration, urine output, skin hydration, blood markers and perceptual responses at multiple intervals during a four-hour period.
They found that ZeroLyte outperformed water at each post-rehydration time point, with participants producing roughly half the urine volume compared to the plain water condition, an indicator of improved fluid retention.
"In this study, we observed that electrolyte composition plays a critical role in post-exercise rehydration," said Dr Stavros Kavouras, professor and director of the Hydration Science Lab at ASU.
The ZeroLyte formulation demonstrated improved fluid retention compared to water alone, which is an important factor in effective hydration.
TraceMaterials stated that ZeroLyte contains no sugar of any kind, in contrast to some other sugar-free products that may contain ingredients such as allulose.
This clinical validation of ZeroLyte, the company says, therefore makes a meaningful distinction in the hydration category.
"This research confirms that the right electrolyte blend is the key to superior hydration," added Darrin Starkey, Manager of Education and Training at Trace Minerals.
ZeroLyte was designed to replenish what the body loses during exercise and now we have evidence that the first clinically studied, truly sugar-free electrolyte drink can restore body fluids two times faster than water.
