Last summer, GU reformulated their Brew sports drink to have a bit lighter carbohydrate load and improved electrolyte profile. Now, for summer 2014, they’re adding four new flavors, including the unflavor Tastefully Nude. It’s joined by Lemon Tea, Watermelon and Blueberry Pomegranate.

The new formulation has 70 calories and 19 grams of carbohydrates per serving, with 250mg of sodium and 30mg of potassium in all but the Blueberry Pomegranate, which bumps up to 500mg of sodium. Carbs come from maltodextrin and fructose in a 50-50 balance.

The entire line uses a lighter flavor profile since everything tastes sweeter and stronger during hard exercise, and the new options help prevent “flavor fatigue”. Brew comes in 24-serving canisters ($20) and single-serve packets ($1.50).
