Built Bar Lawsuit: What the Protein Class Actions Allege About Built Brands' Labels

Built Brands LLC, the American Fork, Utah-based maker of Built Bar and Built Puffs protein bars, has been hit with two proposed federal class action lawsuits accusing the company of overstating the protein content advertised on its packaging. The first, Palacios v. Built Brands LLC, was filed in California federal court on April 16, 2024, alleging that bars labeled as containing 17 grams of protein per serving did not consistently meet that figure in independent laboratory testing. A second action, brought by plaintiff Sean Sullivan and filed in U.S. District Court in July 2024, made similar allegations across the company's broader Built and Puffs product lines, which advertise 15 to 19 grams of protein per bar. Each suit seeks more than $5 million in damages and class certification under federal and state consumer protection laws.

The cases sit inside a fast-growing wave of false-advertising litigation targeting high-protein and high-performance food products — a category whose marketing has come to depend heavily on a small set of nutrition claims printed prominently on the front of the package. This article explains what the Built Bar plaintiffs allege, how the legal framework works, and what consumers should know about their rights when a label and a laboratory disagree.

What the Built Bar lawsuits allege

The two lawsuits make a structurally similar argument: that Built Brands marketed its bars based on a protein figure that the actual product does not deliver. In Palacios, the plaintiff — a San Diego fitness consumer — purchased a variety pack of Built Protein Bars based on the front-label promise of 17 grams of protein per bar. He alleges that he paid a premium price specifically because of that protein content and that independent third-party laboratory testing showed the bars contained materially less protein than advertised. The complaint frames this as both a false-advertising violation and a breach of warranty.

The Sullivan complaint extends similar testing-based allegations across additional Built products, including the Built Puffs line. According to that filing, Sullivan directed independent laboratories to test multiple bars and concluded that the 15–19 gram range advertised on the packaging did not match the measured protein content.

Both complaints invoke the standard set of consumer-protection claims used in food-labeling class actions: violations of state false-advertising and unfair-competition statutes, breach of express warranty (the protein figure on the label is treated as a contractual promise), breach of implied warranty of merchantability, and unjust enrichment. Palacios additionally relies on California's Unfair Competition Law (Business and Professions Code § 17200), the False Advertising Law (Business and Professions Code § 17500), and the Consumers Legal Remedies Act (Civil Code § 1750), which together form the backbone of California consumer-protection litigation.

Built Brands has not been adjudicated liable. The company has not publicly admitted wrongdoing, and the cases remain in early procedural stages. No court has certified a class as of the most recent docket activity.

The FDA rule the cases turn on

The legal weight of these complaints depends on how far the alleged measured values fall below the labeled values — and whether that gap exceeds the tolerance the U.S. Food and Drug Administration permits.

Federal nutrition-labeling regulations are codified at 21 C.F.R. § 101.9. For compliance purposes, the rule divides nutrients into two categories. Class I nutrients are added (fortified) nutrients in fabricated foods and must, on testing, generally be present at 100 percent or more of the value declared on the label. Class II nutrients are naturally occurring (indigenous) nutrients — including vitamins, minerals, protein, total carbohydrate, and dietary fiber — and must be present at a level at least equal to 80 percent of the value declared on the label. The FDA's Guidance for Industry on developing and using nutrition-labeling databases spells out both standards in detail.

The practical effect is that a protein bar advertising 17 grams of protein per serving is, at a minimum, expected to deliver at least 13.6 grams in laboratory testing under the Class II 80-percent floor — the threshold consumer-protection plaintiffs most often cite when alleging that protein content was overstated. (Where protein is added through fortification, the stricter Class I 100-percent floor applies.) If independent testing shows measured values below the applicable threshold across multiple samples, the product may be classified as misbranded under section 403 of the Federal Food, Drug, and Cosmetic Act, and that finding can support state-law false-advertising claims.

This is the threshold the Built Bar lawsuits are testing. Neither complaint has been resolved on the merits, and Built Brands may dispute the methodology used by the plaintiffs' testing laboratories — testing methodology is a frequent battleground in nutrition-labeling cases. A current example is the broader debate over how protein bars should be tested at all: in March 2026, the protein-bar brand David Protein faced a separate class action alleging inflated protein and understated calorie counts, and publicly contested the lawsuit's reliance on bomb calorimetry as the measurement method, arguing it does not accurately capture how certain ingredients are metabolized. That dispute illustrates how laboratory science can become as litigated as the labels themselves.

How false-advertising class actions are built

Food-labeling class actions follow a recognizable structure. Understanding the structure helps consumers evaluate news of a new lawsuit and decide whether they may be affected.

The first step is independent testing. Plaintiffs' counsel commission an accredited laboratory to test multiple lots and flavors of the product against the values on the label. The testing must be repeatable and the methodology defensible — defendants routinely attack the chosen method, the sample size, and the chain of custody.

The second step is the complaint. The plaintiffs assert claims under state consumer-protection statutes (which vary materially from state to state), federal warranty law under the Magnuson-Moss Warranty Act, and common-law theories such as unjust enrichment. The complaint typically seeks compensatory damages (the price premium consumers paid for the inflated claim), injunctive relief (a label change), and attorneys' fees.

The third step is class certification under Federal Rule of Civil Procedure 23. The plaintiffs must show that common questions of law and fact predominate over individual issues. In food-labeling cases, the central common question is usually whether the label was deceptive to a reasonable consumer — a standard that, in California, comes from Williams v. Gerber Products Co., 552 F.3d 934 (9th Cir. 2008).

The fourth step is either a motion to dismiss, summary judgment, settlement, or trial. The vast majority of certified consumer class actions settle. When they do, the settlement typically provides a small per-claimant payment to consumers who can document a purchase, plus injunctive relief that requires the defendant to revise its labeling.

What the Built Bar plaintiffs are seeking

Both Built Bar complaints request the standard remedies available under federal and California consumer-protection law:

The total damages sought in Palacios exceed $5 million — the threshold for federal jurisdiction over a class action under the Class Action Fairness Act of 2005, 28 U.S.C. § 1332(d).

What this means for Built Bar consumers

If you have purchased Built Bar or Built Puffs products, here is what the litigation status currently means in practical terms.

You are not yet a member of any certified class. Class certification has not been granted in either case as of the most recent public docket activity. Without certification, no consumer is bound by — or entitled to recover from — a class judgment, and no settlement has been announced.

Keep your purchase records. If a class is later certified, eligible consumers will typically be identified by purchase receipts, loyalty-program records, or sworn declarations. Receipts, online order histories, and packaging photos that include lot numbers can support a claim if a settlement fund is later created.

You retain individual rights. Even if a class is certified and a settlement is reached, consumers usually have the option to opt out and pursue an individual claim — though the per-person damages in food-labeling cases rarely justify individual litigation. The typical outcome for consumers in these cases is a small payment per purchased unit, sometimes capped, and a label change going forward.

Watch for the official settlement website. If the case settles, the parties will post a court-approved notice on a dedicated settlement website with claim forms, deadlines, and eligibility criteria. Reliable secondary sources for class action news include ClassAction.org page and TopClassActions.com. AttorneyReview also publishes a monthly roundup of open class action settlements that consumers can claim.

The bigger picture: a wave of high-protein-product litigation

The Built Bar complaints arrived during a period of intensifying scrutiny of protein and "high-protein" claims across the snack and supplement industries. In 2024 and into 2026, similar proposed class actions have been filed against several major protein-bar brands, including Kellogg's RXBar, Alpha Prime Supplements, and most recently David Protein, whose 28-gram, 150-calorie bar drew a separate federal class action in early 2026 alleging both inflated protein figures and understated calorie counts. Across these cases, the playbook is consistent: an accredited laboratory tests multiple lots, the complaint cites 21 C.F.R. Part 101, and the plaintiffs invoke state consumer-protection statutes — most often California's UCL and FAL.

The trend is partly a response to the protein category's marketing model. Front-of-package nutrition claims drive purchase decisions in a category where consumers are explicitly buying nutrient content rather than flavor or convenience. When the claim is the product, the claim is also the legal exposure.

For consumers, the practical takeaway is straightforward: nutrition claims printed on packaging are not always supported by the underlying product, and federal regulators rarely test individual products proactively. Most enforcement happens through private litigation, which is precisely why proposed class actions like the Built Bar cases exist.

Frequently Asked Questions

Is the Built Bar lawsuit a settlement I can claim now?

No. Both Palacios v. Built Brands LLC (filed April 16, 2024) and the Sullivan action (filed July 2024) are pending proposed class actions. No class has been certified, no settlement has been reached, and no claim form is available for consumers at this time.

What protein content do the lawsuits allege Built Bars actually contain?

The complaints allege that independent third-party laboratory testing showed the bars contained materially less protein than the 15–19 grams advertised on packaging, but neither complaint has been adjudicated, and Built Brands has not admitted to any specific shortfall. The exact measured values would be presented as evidence if the cases proceed past dismissal motions.

How much protein is a Built Bar legally required to contain?

Under 21 C.F.R. § 101.9(g), naturally occurring protein (a Class II nutrient) must be present at a level at least equal to 80 percent of the value declared on the label. For a bar advertised as 17 grams, that translates to a minimum measured value of approximately 13.6 grams. Where protein is added through fortification (Class I), the actual content must generally equal at least 100 percent of the declared label value.

What law are the plaintiffs using?

The Palacios complaint asserts claims under California's Unfair Competition Law (Business and Professions Code § 17200), the False Advertising Law (§ 17500), the Consumers Legal Remedies Act (Civil Code § 1750), and federal warranty law. The Sullivan action asserts comparable theories under federal and applicable state consumer-protection statutes.

Has Built Brands responded publicly?

Built Brands has not publicly admitted wrongdoing. The company has been involved in separate litigation, including a 2024 trade-secret action it filed against the Utah startup Blue Unicorn — a case that was dismissed in November 2025 — but those matters are unrelated to the protein-content class actions.

What can I do if I bought Built Bars and feel I was misled?

Save your receipts, take photographs of any packaging you still have (lot numbers and sell-by dates can be useful), and monitor the official court dockets and class-action news sites for updates. If a class is certified and a settlement reached, consumers will be notified through a court-approved notice plan. You can also file a complaint with the FDA's MedWatch program for misbranded food products and with your state attorney general's consumer-protection office.

Could I sue Built Brands individually instead of waiting for a class action?

You can, but the economics rarely work for individual food-labeling claims. The price premium attributable to a single mislabeled bar is small relative to the cost of litigation. Class actions exist precisely because individual recovery for low-dollar consumer harms is impractical. An attorney can review your specific situation and explain whether an individual claim is feasible.

Do the Built Bar lawsuits cover the Built Puffs line as well?

The Sullivan complaint encompasses both Built Bars and Built Puffs products, alleging that both lines fall short of the 15–19 grams of protein advertised on packaging. The earlier Palacios complaint focused on the 17-gram Built Protein Bars purchased in a variety pack.

How long do food-labeling class actions typically take?

Most consumer class actions take two to four years from filing to final settlement, depending on motions practice, discovery, class certification proceedings, and the multi-step approval process required under Federal Rule of Civil Procedure 23. Cases that go to trial take longer.

What is the difference between an FDA enforcement action and a class action?

An FDA enforcement action is brought by the federal government and can result in warning letters, recalls, seizure orders, or injunctions — but does not typically award money to individual consumers. A class action is a private civil lawsuit brought on behalf of consumers and seeks monetary damages plus injunctive relief. The two can run in parallel; an FDA finding of mislabeling can be referenced in a private lawsuit, and vice versa.
