According to the 35-page lawsuit, the packaging for Nutriflair’s Premium Berberine+ with Ceylon Cinnamon is prominently labeled with the promise of “1200MG PER SERVING” in the same font and color as “Berberine+,” leading consumers to reasonably assume that each serving of the supplement contains 1,200mg of berberine.
However, the complaint alleges that third-party laboratory analyses have revealed that the Nutriflair berberine supplements contain only between 170mg and 222mg per serving, around 978mg to 1,030mg less than the advertised 1,200mg.
Per the complaint, berberine is a compound primarily associated with the treatment of type 2 diabetes, high blood pressure, canker sores and high cholesterol, and has recently achieved popularity as a weight loss aid. When consumers look to buy berberine herbal dietary supplements, dosage is a material factor in their decision-making process, as they must rely on the dosage-per-serving representations made by the supplement producers, the filing states.
Had consumers known that Nutriflair’s berberine supplements did not contain the advertised 1,200mg of berberine, they either would not have purchased the supplements or would have paid significantly less for them, the lawsuit contends.
Additionally, the lawsuit states that the FDA mandates that an accurate measure of “100% of the volume or weight” of dietary ingredients like berberine must be “declared on the label” of the products, and that failure to do so violates both FDA regulations and the Federal Food, Drug and Cosmetic Act (FDCA). Per the complaint, Nutriflair knew or should have known about the discrepancy between its advertised and supposed actual berberine content in its supplements and has knowingly deceived consumers while violating the law.
The Nutriflair class action lawsuit seeks to represent anyone who, while in California or any state with similar laws, purchased Nutriflair’s Premium Berberine+ with Ceylon Cinnamon for personal use and not for resale within the applicable statute of limitations period.
