Liquid Death Allulose Lawsuit, Were You Affected? Williamson v. Supplying Demand, Inc., No. 4:26-cv-08839

Liquid Death’s maker, Supplying Demand, Inc., is facing a class action — Williamson v. Supplying Demand, Inc., No. 4:26-cv-08839 — over claims its “Zero Sugar” energy drinks aren’t actually sugar-free. Quick answer: if you bought a can of Liquid Death Sparkling Energy in the last four years, you’re likely included. The lawsuit says allulose, the second ingredient listed on the can, is a sugar under federal law — no matter what the front label promises.

Who Is Supplying Demand and Why Is It Being Sued Over Sugar Claims?

Supplying Demand, Inc. is the California corporation behind Liquid Death, the canned-water-and-energy-drink brand known for its skull-branded cans and “murder your thirst” tagline. The company built its Sparkling Energy line — Murder Mystery, Scary Strawberry, Orange Horror, and Tropical Terror — around a “Zero Sugar” promise aimed at health-conscious buyers willing to pay a premium for it. That promise is now in court, because the ingredient the company uses to sweeten the drinks without table sugar is, under the regulation that defines the word, sugar.

What Did Liquid Death Do to Customers Buying “0g Sugar” Drinks?

Every can of Liquid Death Sparkling Energy carries the same front-panel claim: “0g Sugar.” The back of the can repeats it. But run down the ingredient list — carbonated water, allulose, magnesium lactate, citric acid, L-theanine, stevia leaf extract, caffeine, ascorbic acid, natural flavor, and cyanocobalamin — and allulose sits in second place, right behind water. Ingredients are listed by weight under FDA rules, heaviest first. That makes allulose the main thing actually sweetening the drink.

The timing of the lawsuit isn’t a coincidence. Four weeks before it was filed, the Seventh Circuit decided Franco v. Chobani, LLC, ruling that allulose is a monosaccharide and therefore a sugar under the federal regulation defining “total sugars” — regardless of what the FDA currently lets companies leave off a Nutrition Facts panel. The complaint leans hard on that ruling and puts its own argument bluntly: “There is no such thing as ‘0g Sugar’ allulose; it does not exist.”

This isn’t the only allulose-labeled drink in the crosshairs right now. Our coverage of the Liquid I.V. sugar-free lawsuit tracks the exact same theory against a different brand, filed less than two weeks before this one, over drink mixes where allulose is the single most predominant ingredient.

Even Liquid Death’s own Amazon product page lists allulose right under “Ingredients,” on the same page that advertises zero sugar in the header above it. The lawsuit treats that as the company admitting, in its own marketplace listing, the very thing its front-label marketing denies.

Are You Part of the Liquid Death Allulose Lawsuit?

Here’s exactly how to know if you’re covered by the Liquid Death sugar lawsuit.

You’re likely covered if you:

• Bought a can or 12-pack of Liquid Death Sparkling Energy in the last four years, in any of its four flavors or a variety pack
• Purchased through Target, Walmart, CVS, Albertsons, Vons, Pavilions, Ralphs, another grocery store, or Amazon
• Live in California — you’d fall into both the nationwide class and a narrower California subclass with its own state-law remedies
• Bought the drinks for yourself or your household rather than for resale

You’re probably not covered if you:

• Only bought Liquid Death’s still or sparkling water — this suit is specifically about the Sparkling Energy line
• Purchased the product for resale rather than personal consumption
• Are an employee or immediate family member of Supplying Demand, Inc.

Liquid Death Buyers Outside California — Are You Still Covered?

Yes. The complaint proposes a nationwide class covering purchasers anywhere in the U.S., plus a narrower California subclass with additional state-law claims. You don’t need to live in California, or have bought your can there, to be part of the broader group.

If there’s a can of Murder Mystery or Scary Strawberry in your fridge right now, and you bought it sometime in the last four years — you’re very likely in this class, wherever you live.

Not sure if you qualify for the Liquid Death allulose lawsuit? A free consultation with a consumer fraud attorney can help you sort out where you stand.

What Are Liquid Death Allulose Plaintiffs Asking the Court to Award?

The complaint pleads an amount in controversy above $5,000,000 to satisfy federal jurisdiction requirements — that’s a threshold, not a settlement number. Plaintiffs are asking for class certification, damages, restitution, disgorgement, punitive damages, and an injunction that goes beyond just fixing the label; the complaint asks the court to require an advertising campaign correcting what it calls a public misperception the marketing created. No money yet. No claim form yet.

What Could Liquid Death Buyers Receive If This Case Settles?

Supplying Demand hadn’t responded to the complaint as of this writing, and no court has ruled the labeling actually violates the law. If the case eventually settles, payouts in food-labeling class actions like this one have historically run to a few dollars per purchase — the 12-pack at issue retails around $21.99 — but that’s a rough pattern from other cases, not a promise here. A consumer fraud attorney can walk you through what comparable allulose and sugar-labeling suits have paid so far.

This case is three weeks old. The underlying Chobani ruling it depends on is barely seven weeks old. Realistically, you’re looking at a year or more before there’s an actual number to talk about.

What Should Liquid Death Buyers Do Right Now?

1. Skip the “sign up” instinct. There’s no claim form at this stage, and there won’t be one until the case resolves.
2. Keep receipts or order history if you have them. They’re useful later, though usually not required to eventually join a settlement.
3. Don’t worry about a lead-plaintiff deadline. This is a consumer class action, not a securities case — James Williamson is already proposed as the representative plaintiff.
4. Watch the CLRA clock. Plaintiff’s counsel sent Supplying Demand a demand letter on August 6, 2026. If the company doesn’t offer corrective relief within 30 days, the complaint will likely be amended to add damages claims under California’s Consumers Legal Remedies Act.
5. Follow the docket. The case is No. 4:26-cv-08839 in the Northern District of California, with an initial case management conference set for November 27, 2026.
6. Talk to an attorney if you’re considering an individual claim. A consumer fraud attorney can tell you honestly whether that makes sense given the size of a typical purchase.

Liquid Death Allulose Lawsuit — Frequently Asked Questions, No. 4:26-cv-08839

Is there a class action lawsuit against Liquid Death for its sugar claims right now?

 Yes. Williamson v. Supplying Demand, Inc., No. 4:26-cv-08839, was filed August 24, 2026, in the Northern District of California, alleging Liquid Death’s “0g Sugar” and “Zero Sugar” claims are false because its Sparkling Energy drinks contain allulose.

Do I need to do anything right now to be part of the Liquid Death lawsuit? 

No. The case hasn’t been certified as a class action, and there’s no claim form yet. If you bought the Sparkling Energy line in the past four years, that’s enough for now.

When will the Liquid Death allulose case settle?

 UNVERIFIED — no trial or settlement date has been set. An initial case management conference is scheduled for November 27, 2026, which is a procedural step, not a resolution.

Can I file my own lawsuit against Liquid Death instead of joining the class?

 Yes, though for a product this inexpensive, an individual lawsuit rarely makes financial sense next to a class action. A consumer fraud attorney can walk you through the trade-offs.

How will I find out if the Liquid Death lawsuit settles? 

Court filings in Case No. 4:26-cv-08839 are public record. If a settlement is reached, this article will be updated with claim instructions.

What does the CLRA demand-letter deadline mean for the Liquid Death case?

 It isn’t a lead-plaintiff deadline — this isn’t a securities case. Under California’s Consumers Legal Remedies Act, plaintiff’s counsel had to give Supplying Demand 30 days’ notice, starting August 6, 2026, before adding CLRA damages claims to the suit.

What specific laws does Liquid Death allegedly violate?

 The complaint alleges violations of California’s Unfair Competition Law, False Advertising Law, and Consumers Legal Remedies Act, plus breach of express warranty and unjust enrichment, all built on the theory that allulose is a “sugar” under 21 C.F.R. § 101.9(c)(6)(ii).

How much could Liquid Death buyers get if this case settles? 

UNVERIFIED — the complaint doesn’t request a specific per-person figure. It pleads an amount in controversy above $5,000,000 to establish federal jurisdiction, not as a proposed payout.
