Study Purpose

The purpose of the Capsimax research study is to assess whether the dietary supplement Capsimax has a mechanism that could decrease obesity, reduce food intake, reduce appetite and change the types of food people prefer to eat.

About the Study

Capsimax is a dietary herbal supplement containing capsaicinoids, one of the most common compounds in chili peppers. Capsimax capsules are also composed of tiny beads which protect the stomach. 

The Capsimax research study will test whether Capsimax has a mechanism that would decrease obesity or the ability to reduce food intake, reduce appetite and change the types of food people prefer to eat.

After an initial screening, participants will complete four study visits and receive capsules containing a double dose, single does, or placebo in a randomized order.  A resting metabolic rate (RMR) test, a food intake test and multiple questionnaires will be completed during each study visit.
