What's different?
LMNT Drink Mix declares 1000mg sodium — roughly 3.3× more than Nuun Sport (300mg). LMNT Drink Mix declares 200mg potassium — more than Nuun Sport (150mg). Formats differ (Powder vs Tablet), which changes how each one is carried and mixed. LMNT Drink Mix does not declare calcium, chloride, carbohydrates in our source, so those cells stay blank rather than zero.
