Official title

A Randomized, Single Center, Double-blind, Three-way Crossover Trial to Evaluate the Efficacy of ONE A DAY Weightsmart Advanced Versus Caffeine and Placebo on Energy Expenditure, Thermogenesis and Perceived Energy Levels in Women.

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The study is considered research because efficacy (how well a drug works) information is needed in healthy, 25-45 year-old, female subjects with moderate caffeine intake. The investigational product is available in the United States without a prescription (over-the-counter) as a nutritional supplement. The purpose of this study is to assess whether One-A-Day Weightsmart Advanced is safe and can increase metabolism and perceived energy in female subjects compared with caffeine or placebo (inactive drug). Participation in this study will last approximately 4 weeks and require about 4 outpatient visits to St. Luk's-Roosevelt Hospital Center. About 21 subjects are expected to participate in this study.
