Life Extension

It all started 40 years ago when something was missing: rigorous research and a rigorous, science-based approach to developing premium, clinically studied formulations. When we introduce supplements into our bodies, we need to be sure that they will deliver the nutritional benefits they promise.

Our true passion and dedication has always been driven by the sole purpose of optimizing your health so you can live a long and happy life.

Since then, we've spent decades reimagining how to create cutting-edge, effective formulas, each based on rigorous standards and the latest scientific discoveries. The process is complex, but the end result is transparent: a Certificate of Analysis (COA) for every product we make that we provide to you.

We welcome independent testing and are proud to be officially recognized by ConsumerLab.com as the Best Catalog/Online Seller - 5x Winner.† We earned it by prioritizing your health over our profits by sourcing only the finest raw ingredients from the purity and strength your body deserves. And unlike other brands, over 99% of our supplements are made in the USA.


We understand that each person's health needs are unique. As your personal health advocate, we offer a free health consultation and hassle-free returns throughout the year. No wonder 98% of our clients recommend us to their friends and family.

Welcome to Life Extension®, where the science of a healthier life is more than just words, it's what we strive for every day.
