The 20-page lawsuit contends that Raw Nutrition has misled consumers by uniformly representing in advertising and on product packaging that each flavor of its Raw Isolate shakes contains 30 grams of protein per serving. However, the case states that independent, third-party testing commissioned by the plaintiff’s counsel found that six varieties of Raw Isolate shakes contained anywhere from seven to 12 percent fewer grams of protein per serving than advertised. 

The case contends that Raw Nutrition’s apparent misrepresentation of the shakes’ protein content per serving is an attempt to gain a share of consumers’ increased focus on protein supplements and protein-centered diets, driven by demand for products that support muscle growth, weight training, and fat reduction.

The case stresses that consumers have become “conditioned to rely” on nutritional representations set by manufacturers, particularly for products marketed with claims they “cannot confirm or disprove [sic] simply by viewing or even consuming the products.”

The lawsuit argues that Raw Nutrition, as the manufacturer, has superior knowledge of the specific nutrient breakdown of its protein shakes and has nevertheless chosen to falsely advertise the supplements as having a higher protein content.

According to the filing, the protein in the Raw Nutrition shakes at issue is derived from milk protein isolate and calcium caseinate, processed compounds added to provide refined protein content. Because these are added ingredients, they are considered “Class I” foods under the Code of Federal Regulations, which requires that labeled nutrient amounts be met or exceeded, but not fall short, in a product, the case relays.

According to the complaint, independent testing conducted in December 2025 revealed protein content shortfalls in the shakes ranging from seven to 12 percent across the tested flavors:

• RAW Cookies & Cream: 27.9 grams per serving (93 percent of the stated content);
• RAW Chocolate: 27.4 grams per serving (91 percent);
• RAW Vanilla: 27.2 grams per serving (91 percent);
• RAW Mocha Latte: 28 grams per serving (93 percent);
• RAW Strawberry: 26.4 grams per serving (88 percent); and
• RAW Salted Caramel: 27.6 grams per serving (92 percent).

The complaint alleges that consumers paid a higher price for the products based on the amount of protein represented on their packaging, and would not have paid as much, or bought them at all, had they known the protein content per serving was overstated.

The Raw Nutrition Class Action Lawsuit looks to represent all California consumers who purchased Raw Isolate Protein shakes within the four years before the filing of the complaint on April 7, 2026.
