The bottom line Nuun Sport Electrolyte Tablets are the 1-calorie effervescent tablet format that beats stick-pack mixes for travel and bottle compatibility at $24 per 4-tube pack. The 1-calorie per tablet fits any diet, the 300mg sodium and 150mg potassium cover light-to-moderate sweat losses, the effervescent dissolve takes 30 seconds in a 16oz water bottle without shaking, the tube format protects tablets from humidity and crushing in a backpack, the wide flavor range (Citrus Berry pack tested) keeps daily use fresh, and the Informed-Sport certification protects athletes against banned substances. The trade is the lower 300mg sodium dose versus 1000mg LMNT and a slight chalky residue from the dissolve.
