LMNTZero Sugar Electrolytes Drink Mix

Overview

LMNT (pronounced "element") built its reputation on one bold idea: many active people, especially low-carb eaters, need more sodium than typical sports drinks provide. Each stick delivers 1,000 mg of sodium, 200 mg of potassium, and 60 mg of magnesium, sweetened with stevia leaf extract and zero sugar. A 30-count box costs about $1.50 a stick, with bundle pricing closer to $1.13.

What reviewers say

Reviewers consistently point out that the sodium dose is the real differentiator: double Liquid I.V. and more than triple Nuun Sport. The sport scientist and dietitian duo at Saturday see value for heavy sweaters and people who want salt outside of training, but note the sodium comes only from table salt and there are no carbs to fuel long efforts. Registered dietitian Katey Davidson walks through when that much sodium makes sense and when it doesn't, and a 30-day trial from PeteOnPurpose weighs it against cheaper DIY alternatives. Critical coverage centers on the 2024 revelation that LMNT's natural flavors use maltodextrin as a carrier, which upset strict keto and carnivore fans and preceded a 2025 class action over its "all natural" and "keto-friendly" marketing. Flavor opinions split: Citrus and Raspberry are crowd-pleasers, while some find every flavor intensely salty.

Who it's for

Heavy or salty sweaters, hot-weather athletes, people who train fasted, and keto or low-carb eaters who feel flat when they skimp on salt. It's not an all-day sipper for everyone; if you're managing blood pressure or kidney health, talk with your doctor first.

Bottom line

On paper, LMNT is the most efficient way to replace serious sweat losses without sugar, and the brand says every lot is third-party tested for heavy metals, microbes, and label accuracy. It lacks an NSF or Informed Sport seal and costs more than tablets, but for its target user, it's the benchmark.
