Six plaintiffs have filed a putative class action in New York federal court against NBTY , Inc. alleging that the supplement manufacturer engages in “protein spiking,” a process in which the protein content of a product is artificially inflated by adding amino acids such as taurine, glycine, arginine, and creatine to produce additional nitrogen—used to calculate the amount of protein. Mencer v. NBTY, Inc., No. 14-5030 (U.S. Dist. Ct., E.D.N.Y., filed August 25, 2014). According to the complaint, NBTY ’s Body Fortress Super Advanced Whey Protein dietary supplement contains approximately 30-percent less whey protein than the packaging indicates. The plaintiffs accuse NBTY of intentionally misleading customers into believing that its product’s 30 grams of protein per serving is derived exclusively from its Super Advanced Whey Protein ingredient rather than from free form and non-protein amino acids. They seek nationwide class certification as well as certification for six state subclasses, an injunction, damages, and attorney’s fees.
