Immunity Reimagined

Dr. Jeffrey Bland & Dr. Austin Perlmutter

Discover an incredible new approach to holistic human health: Balance your immune system and rejuvenate your life!


Learn how immuno-rejuvenation is the gateway to vibrant health.

We often think of immunity as protection from outside microbes, but the truth is far more complex — and inspiring. 

In this cutting-edge course, the founder of Functional Medicine, Jeff Bland, PhD, and Austin Perlmutter, MD, reveal how your immune system dictates your physical and cognitive health – and even how you behave – based on the messages it receives from food, chemicals, and even your thoughts and emotions. 

Immuno-rejuvenation is a science of hope, and Dr. Bland and Dr. Perlmutter offer a holistic approach that puts you in charge. The big bold truth is that when you focus on rejuvenating your immune system, you change your entire life.
