LMNT is a polarizing brand that offers high-sodium electrolyte mixes popular with endurance athletes and keto enthusiasts, but it faces significant credibility issues. Recent independent findings revealed undisclosed maltodextrin in flavored varieties and trace lead in the unflavored version, leading to class-action lawsuits and damage to the brand's reputation for transparency. Additionally, numerous customers report serious issues with shipping and unresponsive support, making it difficult to recommend despite the product's effective electrolyte formulation.

Facts
Better options
Why switch: Uses functionally identical ingredients (table salt, lite salt, citric acid) at a fraction of the cost, though it lacks the convenience and pre-portioned flavors of LMNT.
These are more widely available, often lower in sodium, and may be more affordable for daily hydration needs.
