Zero third-party certifications despite $200M+ revenue
As of April 2026, LMNT holds no NSF Certified for Sport, no Informed Sport, no USP verification, and no Clean Label Project certification, despite estimated revenue exceeding $200 million.
Class action filed: false advertising as "all natural"
Class action filed in Montana federal court with parallel cases in New York and Florida. Allegations include false advertising as "all natural" and "no artificial ingredients" given the undisclosed maltodextrin. Cases were in discovery as of late 2025.
Independent test finds 27 ppb lead (5.4x FDA bottled water guidance)
Lead Safe Mama / Tamara Rubin independent testing found 27 ppb lead in LMNT Raw Unflavored. FDA bottled water guidance is 5 ppb; California Prop 65 safe harbor is 0.5 μg. LMNT claims batch testing and COAs exist but does not publish them publicly.
Co-founder initially denied maltodextrin, then reversed
Co-founder Robb Wolf first publicly denied the presence of maltodextrin when initially reported. He subsequently reversed his position and called it "clearly a mistake." The sequence — denial then admission — undermined brand credibility on ingredient transparency.
Hidden maltodextrin discovered behind "natural flavors" label
Independent analysis confirmed 250-550mg maltodextrin per serving hidden behind the "natural flavors" designation. Maltodextrin has a glycemic index of 85-105 (higher than table sugar), directly contradicting LMNT's "paleo-keto friendly" marketing. The undisclosed maltodextrin exceeded the combined potassium (200mg) and magnesium (60mg) content.

“Verified reply” means we have a dated screenshot of the brand stating this. It is not a score, a rating, or an endorsement, and a brand's silence here is not itself a finding.
