Based on the research and health philosophy of Morley Robbins.
You are tired, pale, and without energy — and you have probably heard it many times from your doctor: "You have iron deficiency. Please take supplements."
Sound familiar? But what if that is not the whole truth?
Morley Robbins — a mineral metabolism expert, founder of the Root Cause Protocol and author of the book Cu-RE Your Fatigue — has spent years researching the relationship between iron, copper, and magnesium. His conclusions are surprising and worth knowing.
The Problem Is Not a Lack of Iron, But Its Dysregulation
According to Robbins, the greatest mistake of modern medicine is that when blood tests show a low iron level, the doctor immediately reaches for iron supplements. Yet iron is often misrepresented as a deficiency, when in reality, in many cases we are dealing with an excess of iron in the body.
How is this possible? Robbins explains that the problem is not how much iron we have in our body, but whether iron is properly managed and transported. And that is the job of copper.
Copper — The Forgotten Hero
This is the heart of Robbins' findings: you cannot produce haem without copper, you cannot produce haemoglobin without copper, you cannot recycle red blood cells without copper — everything related to iron requires copper. Yet this is not taught in the conventional medical system.
The key protein in this process is ceruloplasmin, a protein produced in the liver that contains copper and is responsible for the proper transport of iron in the body. When the level of bioactive copper is too low, ceruloplasmin does not function correctly, and iron begins to accumulate in tissues instead of being properly utilised. The result in a blood test may look like "iron deficiency," even though in reality there may be too much iron — just in the wrong place.
Magnesium — The Key to the Entire System
A single mineral, magnesium, influences as many as 42% of all enzymes in the body. Robbins emphasises that stress — physical, emotional, and environmental — literally burns magnesium out of our bodies. Without adequate magnesium levels, the entire mineral metabolism becomes dysregulated, including the management of iron and copper.
This vicious cycle looks like this:
- Stress burns magnesium
- Lack of magnesium disrupts copper metabolism
- Lack of bioactive copper impairs iron transport
- Iron accumulates in tissues and generates oxidative stress
- The body becomes increasingly fatigued, and we reach for iron supplements — which deepen the existing iron deficiency problem
Why Can Iron Supplements Be Harmful?
Iron in supplement form — particularly inorganic (non-haem) iron, with which many food products are fortified — can, according to Robbins, intensify oxidative stress, destroy copper and magnesium reserves, and accelerate the ageing process and chronic disease. Excess iron in non-mobile form deposits on the cells of many organs, leading to their "rusting" — that is, dysfunction.
Robbins challenges the World Health Organisation's anaemia statistics as misleading and argues that iron deficiency is a myth. The real problem is a deficiency of bioactive iron — iron that is mobile and capable of transporting haem. This form of iron is available in the body when we have an adequate level of copper, since copper is the main regulator preventing oxidative stress and the depletion of magnesium.
What Instead of Iron Supplements?
Robbins proposes an approach known as the Root Cause Protocol, which focuses on:
- Rebuilding bioactive copper — through natural sources such as beef liver, bee pollen, and copper-rich foods
- Replenishing magnesium — particularly in well-absorbed forms
- Retinol (vitamin A) — supporting the correct functioning of ceruloplasmin
- Limiting inorganic iron — avoiding foods artificially fortified with iron or supplementation in tablet form
- Regular blood donation — as a natural way of regulating iron levels in men and post-menopausal women
Other Myths That Robbins Debunks
Robbins also challenges several other common beliefs:
🔸 The Vitamin D Myth — A low vitamin D level indicates problems such as iron accumulation and magnesium deficiency, not a need for more vitamin D3. Supplementing with D3 may deepen this problem.
🔸 The Calcium Myth — Calcium supplements do not build bones as effectively as we think. True bone health depends on enzymes activated by magnesium and copper.
🔸 The Zinc Myth — Excess zinc blocks the absorption of copper, which can intensify iron dysregulation.
Summary
Morley Robbins' approach is revolutionary in its simplicity: instead of treating symptoms, look for the cause. Fatigue and anaemia are often not a lack of iron, but a signal of a deeper mineral imbalance — a deficiency of copper and magnesium, which are essential for proper iron metabolism.
Of course, every case is different, and before changing supplementation it is always worth consulting a doctor or therapist. But it is worth asking yourself: do I really lack iron — or perhaps something else?
