Nuun is the friendliest entry into electrolytes: a fizzy tablet, a tube for your bag, well under ten dollars. The catch is arithmetic.

The real cost: about $274 a year

Nuun Sport costs $7.49 for 10 servings — $0.75 a serving, about $274 a year for daily use (checked July 19, 2026).

What that $0.75 a serving actually buys

An honest, fully printed light dose (300 mg sodium, 1 g sugar) and the best portability in the category. What the cheap sticker hides is a small dose — 25¢ per 100 mg of sodium, pricier than higher-dose rivals.

It might be worth it to you if…

  • You want low-commitment, portable, flavored light hydration
  • A tablet in every bag matters more to you than milligrams
  • You want the cheapest way to try the category

It’s not worth it if…

  • You sweat hard — matching a real dose takes 2–3 tablets, erasing the price edge
  • You compare per milligram — it’s the priciest zero-ish sodium
  • You want a named certification (none shown on the page)

The verdict

As everyday light hydration and travel, yes — it’s excellent at that. As sweat replacement, no. The alternatives page has the higher-dose options that cost less per milligram.
