Pros and cons

Zero-Sugar Electrolyte Drink Mix

  • 1,000 mg sodium per stick, one of the highest doses among popular mixes
  • Zero sugar and a short ingredient list
  • Independent third-party testing of raw materials and finished product
  • Buyers consistently praise taste, easy mixing and being gentle on the stomach
  • 43% of the sodium Daily Value per stick; too much for many people who are not sweating heavily
  • Most flavored sticks contain 300-450 mg maltodextrin as a flavor carrier that is not listed separately
  • About $1.50 per stick ($1.13 in bulk) for what is mostly salt
  • Brand promotes 4-6 g of sodium a day, well above the 2,300 mg limit in the Dietary Guidelines

Sport Electrolyte Tablets

  • Informed Choice certified, plus gluten-free, kosher, vegan and Non-GMO Project certifications
  • Only 1 g sugar and 15 calories per tablet
  • Portable tablet that fits in a pocket or water-bottle routine
  • About $0.53-$0.75 per serving
  • 300 mg sodium is modest for long or hot sessions
  • Taste is polarizing and some flavors are faint
  • Tablets can be slow to dissolve and hard to shake out of the tube
  • Not suitable as a replacement for a medical ORS

Our verdicts

Zero-Sugar Electrolyte Drink Mix

For heavy sweaters, endurance athletes and low-carb eaters, LMNT is one of the best-formulated electrolyte mixes available: a meaningful sodium dose, no sugar and a short ingredient list. For the average person drinking it at a desk, 1,000 mg of extra sodium a day is unnecessary and potentially counterproductive, and the price is hard to justify.

Full review

Sport Electrolyte Tablets

Nuun Sport is a well-certified, low-sugar and reasonably priced way to add electrolytes to everyday drinking and moderate workouts, which makes it our pick for general and athletic use under an hour or two. Heavy sweaters and anyone battling illness-related dehydration should look to a higher-sodium mix or a medical ORS instead.
