Effects of a Thermogenic Dietary Supplement on Metabolic, Hemodynamic, and Mood Responses

Completed · Not applicable · Has a placebo group

Conditions studied: Energy Metabolism, Heart Rate, Blood Pressure, Mood

In brief

This a randomized, double blind, placebo controlled, crossover design study which measures the effect of an available thermogenic dietary supplement on resting energy expenditure (REE), blood pressure and heart rate, and mood changes in moderate caffeine consumers. Participants will complete baseline measurements then ingest one of three pills. Once the pill is ingested, subjects will complete four REEs along with heart rate and blood pressure and appropriate questionnaires. Participants will return two more times, each after a one week washout period, and complete the same protocol with the remaining supplements.
