LMNT made high-sodium hydration mainstream and holds the top electrolyte score on our site. Here’s the file.

LMNT products we’ve scored

The record, in brief

Strengths: 1,000 mg sodium, zero sugar, every amount printed, and NSF Certified for Sport — the strongest credential in the category. Cons: it’s the priciest zero-sugar option per serving and a deliberately maximalist dose. A 2021 Prop 65 lead notice on two flavors is reported in context in the review.

How we score LMNT

Every LMNT product is scored on the same public 100-point methodology as every other brand — formula, dosage & label transparency, testing, value, experience and brand record — with every fact dated and sourced.

Frequently asked questions

Is LMNT worth it?

For hard sweaters and the certification-conscious, yes — it’s the top-scored electrolyte (70/100) with the only NSF Certified for Sport credential in the field. It’s the priciest zero-sugar option, so lighter or cheaper needs point elsewhere. Its worth-it page does the math.

Is LMNT the best electrolyte?

On our rubric it scores highest (70/100), largely on its certification. Our commonly owned Earth Energy (65) is the best zero-sugar value per milligram; which is “best” depends on whether you prioritize certification or price.
