An electrolyte concentrate for producing hydration beverages can include a sea water concentrate which includes natural minerals. A zinc mineral salt is also included as a primary supplemental mineral, while a potassium mineral salt serves as a secondary supplemental mineral. Further, a citric acid is provided in an amount sufficient to lower a pH of the electrolyte concentrate below about 3.0. The electrolyte concentrate can be particularly useful in forming hydration beverages for athletes and individuals to provide rehydration and nutritional benefits with improved flavor and no added sugar.
