The mitochondria are commonly known as the “powerhouse” of the cell, but energy production is only one of the critical roles played by these organelles. This is why mitochondrial dysfunction tends to have many different signs and symptoms, causing practitioners to chase the wrong things. In fact, the average person with a disorder of the mitochondria will see at least 8 doctors before being properly diagnosed.
Dr. Bryan Walsh, ND is with me today to take an in-depth look at how the mitochondria operate and their roles in the body. We discuss free radicals and antioxidants (hint - those supplements don’t do what we think they do!). Bryan describes mitochondrial dysfunction - what causes it, how to assess for it, and what can happen when it goes untreated. If you want to take a deep dive into this subject, go take Bryan’s new course, Everything You Ever Wanted to Know About the Mitochondria - an amazing 16-hour training for practitioners and biochemistry enthusiasts.
