A battle between two dietary supplement manufacturers has revived interested in the intersection between the Lanham Act and federal labeling regulations. The issue: can an advertiser challenge a competitor's product label for false advertising under the Lanham Act if it complies with applicable federal regulations? The Supreme Court of the United States answered the question affirmatively in 2014 with regard to food products, and now the 11th Circuit has weighed in with regard to dietary supplements. In Hi-Tech Pharms, Inc. v HBA Intl's Corp, 2018 WL 6314282, No. 17-13884 (11th Cir. Dec 4, 2018), the Circuit Court ruled that a Lanham Act claim for unfair or deceptive advertising could proceed even if a supplement's label had complied with the requirements of the federal Food, Drug, and Cosmetic Act (FDCA).
