Brief summary: The purpose of this study is to investigate the effects of the dietary supplement oréVida™ (active ingredient on the basis of a culinary herb)administered twice daily in an acute study on an improvement in vigilance, attention, concentration, memory and mood in 45 healthy men and pre-menopausal women, aged 35-50 years, inclusive.

oréVida™ 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. We do not claim that this supplement is meant to treat any ailment.
