The guest on this episode of Bulletproof Radio is Frank Shallenberger, MD, (or Dr. Ozone), a doctor who was referenced heavily in “Headstrong,” a book about cognitive function and mitochondrial hacking. He has been practicing as a physician for more than four decades in both conventional and alternative medicine.

He started as a western medicine doctor, earlier in his career, and then decided that he wanted to know more about health than what happens in a hospital. He decided this after he realized that the human body is a self-healing mechanism and that it is our lifestyle, belief system, bad exercise, and toxins that cause it to break.

Shallenberger is one of the guys who has revolutionized the practice of anti-aging and preventative medicine since the very early days of those fields. He has also patented a method to measure mitochondrial function, metabolism, oxygen utilization and in this episode, we talk about that method, his most recent book, “Bursting With Energy,” and much more.
