A California federal court denied a bevy of motions in a false advertising lawsuit asserting that Nature Made®  glucosamine supplements were no more effective than a placebo. Barrera v. Pharmavite, LLC, No. 11-4153 (C.D. Cal, order entered June 2, 2016). The court first dispensed with the parties’ various expert report objections, finding insufficient grounds to strike or exclude any of the reports, and instead assessed the methodologies employed to determine the weight of the reports as evidence. The court also rejected the defendant’s motion to decertify the class, finding that the plaintiffs’ classes were ascertainable and that common questions regarding reliance and value derived by customers predominate. Additionally, the court denied the defendant’s motion for judicial estoppel, determining that the complaint—from the outset—had challenged the veracity of representations relating to the product’s overall health benefits.
