Walmart Faces Class Action Over Alleged Mislabeling of Great Value Stevia Sweeteners

On October 23, 2026, a California shopper filed a lawsuit in the U.S. District Court for the Northern District of California, alleging that Walmart misled consumers by marketing its Great Value stevia sweeteners as “made with stevia extract” when the products are primarily sweetened with erythritol.

The complaint cites false‑advertising claims and violations of California consumer‑protection statutes, arguing that the labeling caused shoppers to pay more for a product whose sweetness comes mainly from a sugar alcohol.

Laboratory Findings on Product Composition

Independent testing ordered by the plaintiff’s attorneys found that the 80‑count Great Value No Calorie Stevia Packets contain about 94.44% erythritol. The 9.8‑ounce Great Value No Calorie Stevia Sweetener Sugar Substitute was found to be roughly 59.12% erythritol, with the remainder primarily dextrose and maltodextrin. Both items contain only trace amounts of rebiana, a stevia leaf extract.

Although erythritol appears on the ingredient list, the front of the package prominently displays words such as “Stevia,” “Made with Stevia Extract,” and “No Calorie,” without disclosing the proportion of erythritol.

Health Concerns Cited in the Complaint

The lawsuit references research linking erythritol to possible cardiovascular risks and digestive issues. The plaintiff argues that without clear disclosure, consumers cannot make informed purchasing decisions.

Who May Be Covered by the Proposed Class

The proposed class is limited to California residents who purchased the Great Value stevia products during the four years before the filing. The plaintiff’s attorney estimates the class could include hundreds of thousands of shoppers.

Practical Steps for Potential Class Members

Consumers who think they may be covered should keep receipts, packaging, and any documentation related to their purchases. While the complaint does not specify a filing deadline, class members typically must submit claims within a set period after a settlement is approved.

Reviewing ingredient labels on low‑calorie sweeteners can help shoppers avoid unexpected ingredients in the future. If you are unsure whether you have a claim, consulting a consumer‑rights attorney may provide guidance.
