David protein bar lawsuit: what the 0g sugar claim means

What was actually filed, and where

On August 24, 2026, a plaintiff named Vincent Yovino filed a proposed class action in the U.S. District Court for the Northern District of California, case number 3:26-cv-08834. The named defendant is Linus Technology MergerSub, LLC — the corporate entity behind the DAVID protein bar brand. The plaintiff is represented by Treehouse Law, LLP.

Two words matter here: proposed and complaint. A complaint is one side's allegations. No judge has ruled on any of it, no class has been certified, and the company has not yet filed a response. Everything below is what the filing claims, not established fact.

The case invokes the Class Action Fairness Act, which requires more than $5,000,000 in controversy. That figure is a jurisdictional threshold the plaintiff has to plead — it is not a settlement, a fund, or a promise that anyone will be paid a cent.

The allegation: “0g Sugar” versus allulose

DAVID's marketing is built on a three-number promise printed on the wrapper and repeated across its site and retail listings: “28g Protein | 150 Calories | 0g Sugar.” The complaint's core claim is that the last number is wrong.

According to the filing, every DAVID Gold bar is sweetened with allulose — a rare sugar found naturally in figs, raisins, wheat, maple syrup and molasses. Chemically, allulose is a monosaccharide with the same molecular formula as fructose. The complaint points to the federal definition of “sugars” in 21 C.F.R. § 101.9(c)(6)(ii): the sum of all free mono- and disaccharides. If allulose is a free monosaccharide, the argument goes, it is a sugar, and a “0g Sugar” claim on a product containing it is false.

The complaint also cites the label-ordering rule in 21 C.F.R. § 101.4(a)(1) — ingredients are listed in descending order by weight — to argue that the amount of allulose in each bar is not trivial.

The numbers the complaint relies on

The filing quotes press coverage of the original formula's carbohydrate breakdown, which it says came from nutrition information the company itself supplied. It also alleges that the recipe changed in early 2025.

These are allegations drawn from the public record, not lab results commissioned for the case.

Why this case is being filed now

The timing is not random. In July 2026, the Seventh Circuit decided Franco v. Chobani, LLC and held that allulose counts as a sugar under the governing federal regulation, that state-law claims enforcing the same standard are not preempted, and that a “zero sugar” label on a product containing allulose could plausibly deceive a reasonable consumer. The FDA, appearing as a friend of the court at the judges' invitation, answered the question directly: yes, allulose is a “sugar” as defined in § 101.9(c)(6)(ii).

That decision handed plaintiffs' firms a template. The DAVID complaint leans on it heavily — and it is unlikely to be the last “zero sugar” case filed this year. We break the pattern down in zero sugar label lawsuits.

The argument on the other side

There is a real counterargument, and any honest summary has to include it. In 2019, the FDA told manufacturers they may exclude allulose from the “Total Sugars” and “Added Sugars” lines of the Nutrition Facts panel, because allulose is metabolised differently from table sugar and contributes almost no calories. Read the Federal Register notice and the accompanying guidance and you will see exactly that.

So the fight is narrower than the headlines suggest. Nobody disputes that the Nutrition Facts panel may show 0 g of total sugars. The question is whether a front-of-pack marketing claim — governed by the nutrient-content-claim rules in § 101.13 and the misbranding statute at 21 U.S.C. § 343(a)(1) — can say “0g Sugar” when the product contains a compound that is chemically a sugar.

DAVID has not filed a response yet. Expect the company to argue the panel rule, federal preemption, and that no reasonable consumer was misled about calories or carbs.

What buyers should do right now

Almost nothing — and that is the honest answer. There is no settlement, no fund and no claim form. Anyone offering to “file your DAVID claim” today is running a scam; see how to spot class action settlement scams.

What is worth doing is cheap and takes two minutes:

1. Keep any receipts, Amazon order confirmations or subscription emails for DAVID bars — most food settlements pay a small amount with no proof and a larger amount with it.
2. Do not throw away wrappers you already have; a photo is enough.
3. Set a watch on the case so you hear the day a claim site opens, instead of finding out after the deadline.
4. Ignore any email or text asking for payment, a Social Security number or bank login “to process your claim.”

A realistic timeline from here

Based on how comparable food-labeling class actions have moved, here is the shape of what comes next. Dates are illustrative, not scheduled.

The single most likely outcome, statistically, is a dismissal motion that resolves part of the case and a negotiated settlement somewhere in years two to four. A courtroom trial is rare. For the mechanics, see how a class action lawsuit works.

Glossary

Allulose

A rare monosaccharide used as a low-calorie sweetener. It has the same molecular formula as fructose but is largely not metabolised for energy.

Nutrient content claim

A marketing statement about how much of a nutrient a food has — “0g sugar,” “low fat,” “high protein.” Governed by 21 C.F.R. § 101.13.

CAFA

The Class Action Fairness Act, which lets large multi-state class actions be heard in federal court when more than $5 million is at stake.

Proposed class

The group of buyers a plaintiff wants to represent. It only becomes a real class if a judge certifies it.

Preemption

The argument that federal food-labeling law overrides state consumer-protection claims. A standard defence in labeling cases.
