Effects of cogniVida™ on Learning and Memory and in Comparison to Placebo After Long-term Supplementation

The purpose of the study is to examine the efficacy of cogniVida™ on learning and memory performance (executive function, associative, spatial and verbal memory) as well as on mood and attention parameters after four, eight and eleven weeks of supplementation and in comparison with placebo.

cogniVida™ is considered a dietary supplement, and therefore it is not an approved drug by the Food and Drug Administration (FDA). It is regulated like a food. The U.S. Food and Drug Administration does not strictly regulate herbs and dietary supplements. The investigators do not claim that this supplement is meant to treat any ailment.
