The convenient middle option. Nuun's tablets drop into a bottle, travel well and keep sugar low, with about 300 mg of sodium per tab. That's more than the sugar-free minimalists but still short of what a hard, hot session strips out. At around $0.70 a serving it's fair for the convenience.
About 300 mg sodium per tablet plus potassium and magnesium, low sugar, clearly labelled. It sits in the sensible middle: enough sodium for moderate exercise, not enough to lean on for two hot hours. The tablet format is the real selling point.
Great for moderate workouts and travel, where a tablet beats a powder. Heavy sweaters may need two tabs or a higher-sodium powder to keep up.
