Abstract: Embodiments of the present invention are directed to ingredients, formulations, methods of manufacture and use of an oral rehydration solution (“ORS”) in the prevention and treatment of dehydration in humans. More specifically, invention embodiments relate to flavored electrolyte drink mixtures that relieve the dehydrating effects caused by travel, exercise, over-indulgence of toxic substances, and various illnesses in individual subjects. An ORS embodiment of the present invention restores fluid and electrolyte balance in humans as fast and as effectively as IV therapy, and thereby reduces the incidence of dehydration in human populations as well as rehydrating individuals in circumstances where IV therapy is not practical or wanted.
