Nuun Sport scored 54/100: an honest, portable, lightly dosed tablet. Its 300 mg of sodium is the second-lightest among the majors, so buyers who sweat hard — or who did the per-milligram math — go looking for more sodium per dollar. Every alternative here delivers a bigger dose at a lower per-100mg cost, scored on the same rubric.
The alternatives, ranked
How to choose
If what you actually liked about Nuun was the tablet format — a tube in every bag — that portability is genuinely best-in-class, and no powder matches it; keep it for travel and light days. If it was the price, the reframe is that Nuun’s cheap sticker hides a small dose: match a higher-dose rival’s sodium with 2–3 tablets and the savings vanish. For everyday hydration where dose matters, the options above give you more sodium for less per milligram. Full math in the comparison.
Frequently asked questions
What is a stronger alternative to Nuun?
LMNT (1,000 mg sodium), Earth Energy (750 mg) and Waterboy (550 mg) all deliver a bigger dose than Nuun’s 300 mg — and LMNT and Earth Energy cost less per 100 mg of sodium despite higher stickers.
Is Nuun cheaper than the alternatives?
Per tablet, yes ($0.75). Per milligram of sodium, no — at 25¢ per 100 mg it’s pricier than LMNT (13–15¢) or Earth Energy (9–18¢), because its dose is small. Matching their sodium takes 2–3 tablets, erasing the price advantage.
Should I keep Nuun for anything?
Yes — its tablet-in-a-tube format is the most portable in the category, ideal for travel, gym bags and light-activity days. Just pair it with a higher-dose option for heavy sweat sessions rather than stacking tablets.
