LMNT is a health and wellness brand that specializes in zero-sugar electrolyte drink mixes. Designed for individuals following low-carb, paleo, or physically demanding lifestyles, LMNT's mixes aim to replenish electrolytes lost through sweat. Each serving contains a blend of 1000 mg sodium, 200 mg potassium, and 60 mg magnesium. The company was founded in 2018/2019 by Robb Wolf, a former research biochemist and two-time New York Times bestselling author, James Murphy (CEO), Luis Villaseñor, and Nicki Violetti. LMNT emerged from a need for an electrolyte solution without sugar and artificial additives.
LMNT primarily sells its products through direct-to-consumer channels via its website. However, it has expanded into retail partnerships across thousands of wholesale locations in the US, including The Vitamin Shoppe. In addition to its drink mixes, LMNT offers ready-to-drink formats such as LMNT Sparkling, a carbonated beverage. Recent news includes a class action lawsuit filed in May 2025 alleging that LMNT falsely advertises its electrolyte drink mix as "all natural" despite containing maltodextrin. CEO James Murphy is known for his unique work schedule of working three weeks followed by a week off.
