A class action lawsuit alleging that Bai Brands deceptively marketed its WonderWater beverages as free from artificial sweeteners has faced significant legal challenges, mirroring the company’s history of defending similar litigation. The 2024 proposed class action claimed Bai Brands misleadingly advertised its flavored waters as “natural” and sweetener-free despite containing stevia leaf extract, erythritol, or monk fruit extract—ingredients that plaintiffs characterized as artificial sweeteners. Like previous Bai litigation, this case reflects ongoing disputes about how beverages can be labeled and marketed when the definition of “artificial sweetener” remains contested in the courts.

What Is The Bai Brands Artificial Sweetener Class Action About?
The proposed class action filed in 2024 focuses on bai Brands’ WonderWater product line, which the company has marketed as containing no artificial sweeteners. Plaintiffs alleged that consumers paid premium prices based on this “natural” positioning, believing they were purchasing beverages sweetened only with naturally-derived ingredients. However, the lawsuit claims the products actually contain stevia leaf extract, erythritol, and monk fruit extract—ingredients that function as sweeteners despite coming from plant sources. The marketing distinction matters because “artificial sweetener” carries different meanings depending on who’s defining it.
The FDA does not classify stevia or monk fruit extract as artificial additives since they derive from plants rather than being synthesized in laboratories. However, the plaintiffs in this case argued that marketing these ingredients as absent when they perform the exact function of sweeteners constitutes deceptive advertising—a mismatch between what consumers expect and what they receive. This case sits in a legal gray area where product labeling regulations, consumer protection laws, and the definition of “natural” ingredients collide. Bai Brands’ previous experience with similar litigation in 2018-2019 shows how courts have grappled with distinguishing between truthful labeling and misleading marketing practices.

Bai Brands’ History With Artificial Flavoring Lawsuits
Bai Brands faced earlier class action litigation in 2018-2019 that illustrates why these cases often encounter legal obstacles. That lawsuit challenged the company’s labeling of beverages as containing “no artificial flavors” when they included synthetic malic acid, a flavor enhancement ingredient. In March 2019, a federal judge in the Southern District of california partially dismissed the case, finding that some of the plaintiffs’ claims lacked legal merit. However, the 2019 dismissal was not total—some claims survived, showing that courts sometimes allow these cases to proceed while rejecting others.
The judge’s reasoning distinguished between what labels actually said versus what consumers might have inferred. This partial dismissal pattern demonstrates why artificial sweetener and flavoring cases face inherent vulnerabilities: courts must determine whether the company’s statements were literally false or whether consumers simply made incorrect assumptions about what “natural” or “artificial-free” means. The 2019 precedent is significant because it suggests courts in this jurisdiction view ingredient disclosure strictly. If the current artificial sweetener case faces dismissal, it likely stems from similar reasoning—that while stevia, erythritol, and monk fruit may technically be sweeteners, they are not “artificial” by FDA definition, making any representation about their absence legally defensible.
Understanding The Legal Definition Of “Artificial Sweetener”
One core issue in the Bai Brands artificial sweetener class action involves competing definitions of what constitutes an artificial sweetener. The FDA defines artificial sweeteners narrowly as synthetically produced substances—chemicals created entirely in laboratories. Under this definition, stevia and monk fruit extract fall outside the category because they come from plants, even though both undergo processing and refinement to become shelf-stable sweetening ingredients. Plaintiffs argue that regardless of botanical origin, these ingredients function as artificial sweeteners in that they provide sweetness without calories through chemical modification.
They claim marketing beverages as “free from artificial sweeteners” while using plant-derived alternatives constitutes a material misrepresentation targeting consumers willing to pay premium prices. The consumer expectation argument suggests that people buying “naturally sweetened” beverages expect sweetness from whole foods or simple ingredients like honey or cane sugar—not processed plant extracts. This definitional conflict explains both why the case was filed and why it faces dismissal risk. Courts must choose between the FDA’s technical classification and the plaintiffs’ functional argument about what “natural sweetening” actually means to consumers.

Why Dismissal Motions Succeed In Artificial Sweetener Cases
Federal judges have increasingly been skeptical of class actions based on ingredient labeling unless the company made provably false statements. For example, if Bai Brands’ label said “zero sweetening ingredients” and it contained stevia, that would be clearly false. However, if the label says something like “natural sweetness” or “naturally sweetened,” courts examine whether stevia or monk fruit extract legitimately qualifies as natural—which the FDA says it does. The burden falls on plaintiffs to show not just that marketing was misleading, but that it violated a specific law.
The FDA’s own position that these ingredients are non-artificial makes the legal case harder to win. Additionally, courts consider that a reasonable, informed consumer researching Bai Brands would find detailed ingredient lists readily available, making it difficult to prove they were actually deceived rather than simply not checking the labels carefully. Dismissal also becomes likely when plaintiffs struggle to show they suffered economic injury. If a Bai WonderWater cost the same as comparable artificially sweetened beverages, proving consumers paid a “premium” becomes difficult. Courts may dismiss on the grounds that even if marketing was misleading, no actual harm occurred.
What “Dismissal” Means For Class Action Participants
When a class action is dismissed, it does not necessarily mean the company wins permanently. A dismissal on procedural or technical grounds may allow the case to be refiled with revised allegations, particularly if the judge dismissed “without prejudice” (meaning plaintiffs retain the right to file again). If dismissed “with prejudice,” the claims cannot be refiled against the same conduct. For potential class members who haven’t yet received settlement money, a dismissal is typically bad news.
Once a case is dismissed, there is no settlement fund and no compensation available unless the plaintiffs appeal successfully. Some class actions survive partial dismissals—meaning some claims are thrown out while others proceed, allowing the case to move toward settlement on the remaining issues. This mixed outcome actually occurred in Bai’s 2019 lawsuit, though the current artificial sweetener case’s exact outcome would depend on the specific judge’s ruling. Consumers who believe they were misled about ingredients have other options when class actions fail, including state consumer protection agencies, the FDA’s complaint system, or joining group actions in small claims courts. However, these alternatives typically result in less compensation than successful class settlements.

The Broader Pattern Of “Natural” And “Artificial” Ingredient Litigation
The Bai Brands case reflects a broader trend in food and beverage litigation where companies face challenges over how they describe ingredients that are technically natural but processed. Similar lawsuits have targeted companies marketing beverages sweetened with stevia, monk fruit, or sugar alcohols as “natural” or “free from artificial ingredients” when those sweeteners undergo industrial processing. For example, companies using “natural sweetness from monk fruit” while the fruit itself is harvested, dried, extracted, and combined with other stabilizing ingredients face the question: at what point does processing make a natural ingredient effectively artificial? Courts have increasingly held that if the FDA classifies something as natural or non-artificial, plaintiffs face an uphill legal battle proving the label was materially misleading.
What This Means For Consumers Shopping For Natural Beverages
If the artificial sweetener class action against Bai Brands is dismissed or unsuccessful, it signals that consumers cannot rely on “free from artificial sweeteners” marketing claims to mean the beverages contain no processed sweetening ingredients. This outcome emphasizes the importance of reading ingredient lists rather than relying on front-of-label marketing promises.
For consumers actively seeking beverages sweetened with whole food ingredients like honey, cane sugar, or dates, the takeaway is to verify this in the ingredient list rather than assuming that a claim about artificial sweeteners reveals anything about processing levels or ingredient naturalness. As ingredient litigation continues evolving, the lesson for consumers is that marketing language and legal definitions of “natural” and “artificial” operate differently.
