Headquartered in Barrington, Ill., the Gatorade Sports Science Institute (GSSI) is a research and educational facility established in 1988 to share current information and expand knowledge on sports nutrition and exercise science that enhance the performance and well-being of athletes. The materials and services of the Institute are designed as educational tools for sports health professionals.

GSSI staff scientists study the effects of exercise, the environment and nutrition on the human body using the latest scientific technology and equipment. In addition to the GSSI's own exercise physiology, biochemistry and exercise sensory labs, GSSI also works with leading scientists from universities around the world to further research in exercise science and sports nutrition.

The Institute is advised by several boards who provide advice and information on research topics relevant to the GSSI's mission and offer direction on future educational offerings.

The Institute has become a truly international organization in recent years and currently serves nearly 110,000 members in over 145 countries worldwide.
