Clinical Trial 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.

• Subject is willing to refrain from consuming alcohol 24 h prior to test days.

• Subject is willing to refrain from consuming caffeine and caffeine-containing products 12 h prior to test days.

• Subject has donated more than 300 mL of blood during the three months prior to screening.

• Subject has uncontrolled hypertension (systolic blood pressure =160 mm Hg or diastolic blood pressure =100 mm Hg) as defined by the average blood pressure measured at screening. One re-test will be allowed on a separate day prior to visit 2, day 0 for subjects whose blood pressure exceeds either of these cut points at visit 1.

• Subject has a history or presence of clinically important cardiac, renal, hepatic, endocrine (including diabetes mellitus), pulmonary, biliary, gastrointestinal, pancreatic, or neurologic disorders that, in the judgment of the Investigator, would interfere with the subject's ability to provide informed consent, comply with the study protocol (which might confound the interpretation of the study results), or put the subject at undue risk.

• Subject has had exposure to any non-registered drug product within 30 days prior to the screening visit.

• Use of dietary supplements containing any of the following: ginkgo biloba, St. John's wort, ginseng, gotu kola (Indian pennywort); daily doses of vitamin E (=30 mg/d) or folic acid (=400 ug/d); thiamine, riboflavin, and/or pyridoxine (=2 mg/d); and eicosapentaenoic acid (EPA), docosahexaenoic acid or a combination of EPA + DHA (=500 mg/d) within 2 weeks of screening visit.

• Recent history of (within 12 months of screening visit 1) or strong potential for alcohol or substance abuse. Alcohol abuse is defined as >14 drinks per week (1 drink = 12 oz beer, 5 oz wine, or 1½ oz distilled spirits).
