Loyal GU athletes rave about the lightly sweet taste of the Electrolyte Brew. Box of 16 34g sachets. Please Note: Because GU Electrolyte Brew contains mostly complex carbohydrates instead of tons of sugar, it does not mix well in icy cold water. Use a little warm or room temperature water to mix it and then top it off with cold water.
