Morley Robbins is the creator and founder of The Root Cause Protocol and the Magnesium Advocacy Group. Morley received his BA in Biology from Denison University in Ohio and holds an MBA from George Washington University in healthcare administration. Morley has trained in wellness coaching, nutritional counselling, and functional diagnostic nutrition.
He is also known as the Magnesium Man due to his extensive research into and understanding of magnesium’s role in the body. Morley’s research saw him deciphering the intricate relationship between magnesium, iron, copper, and calcium as a way to free ourselves from illness and dis-ease. As a certified health coach with an expertise in Hair Tissue Mineral Analysis (HTMA), Morley has performed thousands of RCP one-on-one consultations, helping people feel better by getting to the root cause of their symptoms. The Root Cause Protocol (RCP) we discuss in this podcast was developed by Morley, who transformed a career in the mainstream medical industry into a quest to learn the fundamental components of a healthy metabolism.
The RCP claims to work by restoring balance to the key minerals – magnesium, copper and iron – that must work together in order to optimize energy and increase vitality. Now, the RCP is in Morley‘s new book “Cure Your Fatigue”
This book is designed for those seeking the truth in human metabolism and those wanting to take back control of their health. It is one part textbook and one part user's guide based on a decade of research and client experience

Mindsip insights from this episode:
Consume animal fat to enhance copper bioavailability
You must consume animal-based vitamin A (retinol), found in fats, to activate the pumps that make copper bioavailable in your body.
Address copper loss in ceruloplasmin to regulate iron
The vital copper-carrying protein ceruloplasmin has been steadily losing its copper atoms over the past 70 years, diminishing its ability to regulate iron.
Reduce iron accumulation to slow aging process
The process of aging can be simplified to the accumulation of iron in your body's tissues over time, causing an internal 'rusting'.
Avoid high doses of vitamin C, D, and zinc to preserve copper levels
Taking high doses of ascorbic acid (vitamin C), vitamin D, and zinc together creates a perfect triad for destroying the bioavailability of copper.
Address copper deficiency to manage cholesterol levels
A lack of copper can cause cholesterol to rise, as the body produces more cholesterol to act as a protective sink for oxygen.
Reduce glyphosate use to preserve food's copper content
The herbicide glyphosate removes copper from soil a billion times faster than calcium, drastically reducing its presence in our food supply.
Manage chronic stress to prevent hidden iron deficiency
Chronic stress increases the hormone hepcidin, which sequesters iron in your tissues and makes blood levels appear deceptively low.
Recognize limitations of anemia blood tests for accurate iron assessment
Standard blood tests for iron can be misleading because there is up to 10 times more iron stored in your tissues than is circulating in your blood.
Avoid fortified foods with carcinogenic iron filings
The nine forms of inorganic iron filings used to fortify foods like wheat flour in the US have all been classified as carcinogens.
