In this episode of Cure Your Fatigue, Morley Robbins speaks with Professor James Collins, one of the key scientific figures whose laboratory research helped shape the Root Cause Protocol. Dr. Collins explains—using decades of bench science—why copper is essential for iron metabolism and how iron problems are often issues of iron dysregulation, not iron deficiency. The conversation explores intestinal mineral absorption, copper–iron interactions, hepcidin, ceruloplasmin, stress, anemia, and why much of modern medicine still misses these connections.
