Earlier this week, the FTC announced that supplement marketers i-Health, Inc. and Martek Biosciences Corporation (the Companies) have agreed to settle charges of deceptive advertising for claiming that their BrainStrong Adult dietary supplement will improve adult memory and prevent cognitive decline. BrainStrong Adult, which is sold at drug stores nationally and advertised online and on television, is an omega-3 DHA-based supplement. The Companies claimed that the product was “clinically shown to improve adult memory,” could “naturally support mental clarity,” and “helps protect against normal cognitive decline as we age.”
The FTC alleged that the terms “memory” and “cognitive” function mean many different things. For example, the FTC points out that there is episodic memory (memories of specific experiences), sensory memory (memories of specific sensory perceptions), working memory (short term mental manipulation of numbers), semantic memory (general knowledge, facts, concepts), and procedural memory (learned skills, such as riding a bike). The same is true of cognition. As such, even though BrainStrong Adult was supported by clinical trial evidence showing that participants who consumed 900 mg of DHA daily experienced certain memory-related improvements, because it did not support an improvement in all different variations of memory and cognition, the FTC alleged that the benefits communicated were not properly supported by the study and, thus, the claims were deceptive.
