Hydration I.v. by Trace Minerals is a great-tasting, naturally flavored electrolyte drink mix that has been carefully formulated with 20 times the hydrating power of an average 16-ounce bottle of spring water because of its full spectrum of electrolytes, which helps hydrate the body faster. In addition, when compared to a sports drink, Hydration I.v. has 3 times the electrolytes, one-third the sugar and carbs, half the calories, and five essential vitamins for energy and recovery. To use a single serve travel packet, open and add contents to 16 oz of water and mix (or shake) well. Take as needed to support hydration depending on physical activity. Store in a cool, dry place. Some caking may occur but does not affect the quality of the product.
