Liquid I.V. class action lawsuit overview:
- Who: Plaintiff Karen Hook filed a class action lawsuit against Unilever United States and The LIV Group Inc.
- Why: Hook alleges Liquid I.V. is falsely advertised as “sugar-free.”
- Where: The Liquid I.V. class action lawsuit was filed in California federal court.
A new class action lawsuit accuses Unilever United States and The LIV Group of falsely advertising their Liquid I.V. Hydration Multiplier electrolyte drink mix products as being “sugar-free.”
Plaintiff Karen Hook filed the class action complaint against Unilever and LIV on Aug. 7 in California federal court, alleging violations of California consumer protection laws.
The lawsuit alleges that Unilever and LIV falsely advertised their Liquid I.V. Hydration Multiplier electrolyte drink mix products as “sugar-free,” “zero sugar” and “0 sugar” despite containing allulose, a monosaccharide sugar.
The plaintiff claims the labeling concedes that allulose adds a “trivial amount of sugar,” which she argues is misleading since four grams of sugar per serving is not a trivial amount.
“Four grams of sugar per serving is eight times more than the maximum amount of sugar (less than 0.5 grams) that federal and California law permit in a product labeled ‘sugar free,’” the Liquid I.V. class action lawsuit says.
Hook’s lawsuit cites a recent ruling by the U.S. Court of Appeals for the Seventh Circuit, which confirmed that allulose is a sugar under federal regulations and that consumers can be deceived by “sugar-free” labeling on products that contain allulose.
Companies allegedly took advantage of demand for sugar-free products
The class action lawsuit claims that Unilever and LIV sought to take advantage of consumers’ desire for sugar-free products by misleadingly labeling their products, giving them an unfair competitive advantage over lawfully acting competitors.
Hook says she purchased the Liquid I.V. Lemon Lime Hydration Multiplier electrolyte drink mix from a Costco location in San Jose, California, in July 2026, relying on the “sugar-free” representation on the label. She says she would not have purchased the product, or would have paid less for it, if she had known it contained sugar.
Hook wants to represent a California class of consumers who purchased the Liquid I.V. Hydration Multiplier electrolyte drink mix products during the past four years.
She is suing for violations of California’s Unfair Competition Law, False Advertising Law and Consumers Legal Remedies Act as well as breach of express warranty and unjust enrichment.
The plaintiff seeks certification of the class action, damages, restitution, disgorgement, injunctive relief, punitive damages, attorneys’ fees and costs and a jury trial.
Meanwhile, a separate Liquid I.V. class action lawsuit claims the company sold Lemon Lime Electrolyte drink mix packets with nonfunctional slack-fill.
