A class-action lawsuit alleges that David Protein, a nutrition company founded in 2023, has misrepresented the calorie and fat contents of its popular protein bars. The plaintiffs claim that independent testing found the bars contain up to 83% more calories and 400% more fat than what is stated on the product labels.

Why it matters

As a company known for catering to health-conscious consumers, this lawsuit poses a significant challenge for David Protein's brand reputation and consumer trust. Accurate nutritional labeling is a critical issue for the food industry, with regulators closely monitoring compliance.

The details

The lawsuit, filed in the U.S. District Court for the Southern District of New York, was brought by three individuals who purchased David bars. They claim that testing using the Atwater factors method found the bars contain "way more" calories and fat than the labels state. Specifically, the lawsuit alleges the calorie content exceeds the label by up to 83% and the fat content is underestimated by as much as 400%.

  • The lawsuit was filed on January 23, 2026.
  • David Protein launched its protein bars in 2024.
