Inside the Scandal Over Liquid I.V.’s “Sugar-Free” Label

The Facts

The front of the Liquid I.V. packages reproduced in the complaint makes an uncomplicated promise: “SUGAR-FREE.” Other panels shown in the same filing are more complicated. They identify allulose as the first ingredient, disclose either “4g Allulose Per Serving” or “5g Allulose Per Serving,” and carry a footnote stating that an ingredient “adds a dietarily insignificant amount of sugar.”

The Nutrition Facts panels shown in the exhibits list zero grams of Total Sugars. The plaintiffs nevertheless argue that the separate front-label claims violate federal and California rules because allulose is a monosaccharide and, in their reading of the regulations, must count as sugar when determining whether a product may be called “sugar free.”

The challenged products include numerous flavors and pack sizes of Liquid I.V. Hydration Multiplier Sugar-Free Electrolyte Drink Mix, licensed and co-branded versions, and the Sugar-Free Energy Multiplier. The complaint says the representations appeared on packaging, Liquid I.V.’s website, Amazon listings, and other online marketing.

What the Labels Say

The exhibits do not present a case in which sugar is alleged to have been discovered only through laboratory testing. The amount of allulose appears on the packaging itself. The dispute concerns what that ingredient is and whether the prominent no-sugar message can legally coexist with the other disclosures.

How Allulose Became the Legal Fault Line

Allulose is the hinge of the case. The complaint cites scientific literature describing it as a monosaccharide, meaning a carbohydrate made from one sugar unit. The cited literature also describes allulose as approximately 70% as sweet as sucrose, or table sugar, and as a bulk sweetener used in quantities measured in grams.

The plaintiffs quote the Food and Drug Administration’s general definition of Total Sugars as “the sum of all free mono- and disaccharides.” They also cite a 2016 FDA rulemaking statement that allulose, “as a monosaccharide,” had to be included in Total Sugars pending any later rulemaking excluding it.

From there, the complaint turns to the rule for nutrient-content claims—the claims placed outside the Nutrition Facts box to characterize a product as “sugar free” or “zero sugar.” The plaintiffs say this is legally distinct from what may appear inside the Nutrition Facts panel.

The footnote does not resolve the issue in the plaintiffs’ view. The cited regulation separately addresses products containing an ingredient understood to contain sugar and permits specified qualifying language. But the complaint argues that this condition operates alongside—not instead of—the requirement that the food contain less than 0.5 grams of sugar. Both conditions must be met, the plaintiffs contend.

That interpretation has not been tested in this case. The supplied source contains no FDA enforcement action involving these products, no agency opinion applying the cited provisions to their labels, and no ruling accepting the plaintiffs’ reading.

What the Claim Meant for the Two Buyers

The named plaintiffs describe a financial injury, not a medical one. Max Nicholas Ulrich says he bought a Lemon Lime 10-count product at a Target store in Santa Rosa, California, on or about July 24, 2026, for approximately $14.99. Sabrina Zahir says she bought a 16-count variety pack through Liquid I.V.’s official Amazon listing on August 26, 2025, for $27.99 while living in Brooklyn.

Both allege that they saw and relied on the “Sugar Free” representation. They say they believed the products contained no sugar and would either have declined to buy them or paid substantially less had they understood allulose to be sugar.

The complaint repeatedly calls the difference a price premium, but it does not calculate that premium. It supplies no comparison prices, consumer survey measuring the label’s value, sales records, or damages model. Those issues would require evidence beyond the allegations in the filing.

Nor does the complaint allege that either plaintiff became ill, experienced a nutritional consequence, or suffered a physical reaction. The asserted harm is that buyers paid for one represented product attribute and allegedly received something different.

The proposed class is not yet a class

Ulrich and Zahir seek to represent a nationwide group of purchasers, plus California, New York, multistate consumer-protection, and multistate warranty subclasses. They allege on information and belief that the proposed classes number in the millions, while acknowledging that the exact number is unknown without discovery.

That estimate has not been proven. A judge would still have to decide whether the case satisfies the requirements for class certification, including whether common issues can be resolved together and whether the named plaintiffs can adequately represent other purchasers.

What the Evidence Establishes and Also What It Doesn’t

The strongest evidence attached to the complaint is the packaging itself. The reproduced cartons pair front-facing “SUGAR-FREE” claims with four- or five-gram allulose disclosures, identify allulose first in the ingredient list, and display the “dietarily insignificant amount of sugar” footnote. The complaint also reproduces marketing language from Liquid I.V.’s website and an Amazon listing.

The plaintiffs use the footnote to support an allegation about company knowledge: they argue that describing allulose as adding an amount of sugar shows The LIV Group knew allulose was sugar. That is an inference advanced by the plaintiffs, not an admission adjudicated by a court since it hasn’t gone to trial yet.

The Legal Fight

The complaint asserts eight causes of action. They include claims under California’s Consumers Legal Remedies Act, Unfair Competition Law, and False Advertising Law; New York consumer-protection and false-advertising statutes; similar laws in other states; breach of express warranty; and unjust enrichment.

The federal food-labeling rules matter because California’s Sherman Food, Drug, and Cosmetic Law adopts federal labeling requirements as state standards. The plaintiffs say they are not trying to enforce federal food law directly. Instead, they use those standards to support claims available under state law.

What the plaintiffs want

The requested relief includes class certification, damages where authorized, restitution, interest, legal fees, and an injunction. The proposed injunction would require The LIV Group to stop using the challenged representations and make disclosures sufficient to correct the alleged public misperception.

These are requests, not remedies the court has granted. Under the California consumer-remedies claim, Ulrich initially sought injunctive relief and reserved the right to seek additional relief after the statutory notice period expired.
