Special K allulose lawsuits

Special K is the clearest cereal example in the allulose litigation wave and one of the strongest tests of the difference between "zero sugar" and "zero added sugar."

We track two verified or cross-checked proposed class actions against WK Kellogg Co involving Special K cereal and allulose:

• Bender-Long v. WK Kellogg Co, filed August 24, 2026; and
• Carr v. WK Kellogg Co, filed September 4, 2026.

The primary Bender-Long complaint does not merely allege that a product contains allulose while carrying a generic sugar claim. It specifically attacks front-of-box "ZERO ADDED SUGAR" and "0g ADDED SUGAR" representations on three cereal products that, according to the complaint and packaging reproduced in it, contain three or four grams of allulose syrup per labeled serving.

No court has made a final finding that WK Kellogg's labeling violated the law.

The verified Special K allulose cases

The federal docket index confirms Ari Bender-Long filed the first case on August 24, 2026. (Justia docket)

The federal docket index confirms Paulette Carr filed the second on September 4. (Carr docket)

Truth in Advertising groups the two cases under Special K cereals and reports the core allegation as zero-added-sugar marketing despite allulose. (Truth in Advertising)

Which Special K products does the primary complaint name?

The Bender-Long complaint identifies three products:

• Special K Plus Strawberry Crème High Protein Zero Added Sugar Cereal, 6.6 oz;
• Special K Plus Strawberry Crème High Protein Zero Added Sugar Cereal, 8.1 oz; and
• Special K Zero Cinnamon Breakfast Cereal, 7.7 oz.

(Bender-Long complaint)

The two Strawberry Crème boxes are treated together in the complaint as the "Strawberry Crème Products."

The Cinnamon product is treated separately because its front-panel wording is slightly different.

What exactly does the complaint say the boxes claim?

The complaint says the Strawberry Crème products repeatedly display:

"ZERO ADDED SUGAR"

The Cinnamon product is alleged to display:

"ZERO"

immediately above:

"0g ADDED SUGAR"

The complaint characterizes those as outside-panel nutrient-content claims that must comply with the federal no-added-sugar rule. (Bender-Long complaint)

This exact wording matters. Calling the case simply a "sugar-free lawsuit" would blur the legal theory.

How much allulose does Bender-Long allege?

The complaint says the products' own labeling quantifies:

• 4 grams of allulose per labeled serving for each Strawberry Crème product; and
• 3 grams per labeled serving for the Cinnamon product.

It alleges WK Kellogg adds allulose syrup during processing while making the zero-added-sugar representations. (Bender-Long complaint)

Those quantities are unusually useful because they are not presented merely as estimates from a plaintiff's laboratory test. The complaint says the labels themselves contain net-carbohydrate calculations that quantify three or four grams of allulose.

That remains an allegation about the legal significance of those disclosures, not a court finding that the front-label claims are unlawful.

The Nutrition Facts panel is not the only thing being challenged

The Bender-Long complaint expressly notes that the Nutrition Facts panels declare zero grams of Total Sugars and zero grams of Added Sugars.

The lawsuit's theory instead focuses on the prominent front-panel statements and on the fact that allulose syrup is allegedly added during processing.

That distinction is central to the allulose litigation landscape.

FDA's October 2020 guidance allows enforcement discretion for excluding allulose from Total Sugars and Added Sugars declarations on the Nutrition Facts panel. (FDA guidance)

The complaint argues that this does not authorize a separate outside-panel "Zero Added Sugar" nutrient-content claim that fails the conditions in § 101.60(c)(2).

The key regulation is § 101.60(c)(2)

This is the major legal distinction between Special K and a case like Franco v. Chobani.

Section 101.60(c)(1) governs sugar-free and zero-sugar claims.

Section 101.60(c)(2) governs terms such as "no added sugar," "without added sugar," and "no sugar added," along with conditions that apply to those representations. (21 C.F.R. § 101.60)

The Bender-Long complaint argues that "zero added sugar" is a reasonable variation of that regulated claim family and alleges that allulose syrup is itself an added sugar within the regulation's framework.

That legal theory has not been finally adjudicated in these Special K cases.

What classes does Bender-Long propose?

The complaint proposes several classes and subclasses:

• a Nationwide Class;
• a Multi-State Consumer Protection Subclass;
• a Multi-State Warranty Subclass; and
• a California Subclass.

The Nationwide Class is defined around people in the United States who purchased the defined products for personal use during the maximum period permitted by law. (Bender-Long complaint)

Those are proposed definitions. No court has certified them in the records reviewed.

What causes of action are pleaded?

The primary complaint contains six counts:

1. California Consumers Legal Remedies Act;
2. California Unfair Competition Law;
3. California False Advertising Law;
4. consumer-protection statutes for the proposed multi-state subclass;
5. breach of express warranty for the proposed multi-state warranty subclass; and
6. unjust enrichment.

(Bender-Long complaint)

The complaint initially seeks injunctive relief under the CLRA and reserves the right to amend after the statutory notice period. That is a procedural pleading detail, not a statement about what relief will ultimately be awarded.

How does Carr fit in?

Carr v. WK Kellogg Co is a separate Central District of California case filed eleven days after Bender-Long.

Its existence, court, date, plaintiff, and defendant are supported by a federal docket index. We also cross-check it against the current Special K tracker.

We have not used the Bender-Long complaint to invent a complete product list, class definition, or cause-of-action list for Carr.

That discipline matters. Two cases against the same company over the same product family can still differ in the exact products purchased, legal claims, proposed classes, and procedural history.

Does Franco v. Chobani decide the Special K cases?

No.

Franco is still important because the Seventh Circuit held that allulose falls within the federal definition of sugar. (Seventh Circuit opinion)

But Franco involved a sugar-free claim under § 101.60(c)(1).

The Special K complaint is built around added-sugar claims under § 101.60(c)(2).

The difference is not semantic. The added-sugar rule asks a related but distinct regulatory question about what is added during processing or packaging.

The Special K cases are also in the Ninth Circuit. Franco is persuasive there, not binding Seventh Circuit precedent.

Current procedural status

Truth in Advertising reports the two Special K allulose cases pending as of the current tracker review. We treat that as current secondary tracker evidence rather than a complete PACER status. (Truth in Advertising)

Recent complaint-based reporting also says WK Kellogg waived service in Bender-Long and identifies an October 26 response deadline. That is a docket-derived scheduling detail, not a ruling on the merits. Because the deadline is prospective and procedural status can change, the site's canonical status module should continue to rely on the structured procedural layer rather than hard-coding that deadline into evergreen copy.

A separate WK Kellogg docket remains outside the allulose count

Our research list also includes Valadez v. WK Kellogg Co., No. 5:26-cv-09060 in the Northern District of California.

The case identity is known, but the current source set does not establish that the complaint concerns allulose.

It therefore should not be counted as a Special K allulose case merely because it names the same defendant and was filed during the same litigation wave.

Has a Special K allulose class been certified?

We have not identified a class-certification order in the records reviewed as of October 4, 2026.

Is there a Special K settlement or claim form?

We have not identified a court-approved settlement, official settlement administrator, or court-authorized claim form in the records reviewed as of October 4, 2026.
