In exchange for participating, you are given free blood tests, nutritional supplements, and personalized consultations that can be worth thousands of dollars.

As a member of the Life Extension Foundation, you seek the latest technological advances to protect against age-related degeneration. As a participant in a clinical study, you gain access to novel nutritional approaches that may significantly improve your health and longevity.

Scientific Research

Before Life Extension brings a product to its members, each component of that product undergoes extensive scrutiny, including evaluation of any available published clinical research studies. In addition, the evaluation process often continues by means of clinical trials conducted in the facilities of Life Extension® Clinical Research, Inc. (LECR), in Fort Lauderdale, Florida, as well as outside Life Extension.

Life Extension Clinical Research comprises physicians, scientists, pharmacists, statisticians, data managers, project managers, and clinical research coordinators. We have consistently and extensively substantiated our products’ potential benefits. These efforts have assisted our organization in creating better ways for our members to maintain and improve their health.

The product development team at Life Extension continually reviews the scientific literature for natural agents that have shown promise in combatting age-related disorders. Life Extension’s clinical studies are designed, managed, and conducted to discover new benefits to Life Extension’s members by providing the highest-quality products and ensuring the safety of our clinical study subjects.
