Ep 64 – Morley Robbins Returns: The Copper-Iron Axis, Indoxyl Sulfate, and Why Everything You’ve Been Told About Anemia Is Wrong

The Root Cause Protocol founder is back — and round two goes deeper than we ever expected.

If you thought Episode 39 covered the copper story, Are you Anemic, or could it be Copper Deficiency? with Morley Robbins, you’ve only scratched the surface. Morley Robbins returned to the Quantum Healthy Podcast for a second conversation, and what unfolded was nothing short of a masterclass in mineral metabolism — one that challenges the very foundation of modern medicine’s iron obsession.

Here’s what’s waiting for you in this episode:

🧪 The Indoxyl Sulfate Bombshell

Andeea asked about indoxyl sulfate¹ – a tough question right at the start, and Morley delivered. In a low-copper, high-iron body (think iron in the tissues), dietary tryptophan — found in everything from sandwich meats to your favorite Thanksgiving protein (turkey -if you are not vegan of course) — gets shunted into indole groups instead of NAD² . The result? A cardiotoxin and uremic toxin that, in severe CKD³ patients, can be 80 times higher than in a healthy person. But what about 60x? 10x? This is a blind spot of staggering proportions.

And here’s where the bowel comes in. When the duodenum hits its mucosal block — the body’s way of saying “enough iron” — the excess doesn’t just vanish. It moves to the colon, where iron becomes, in Morley’s words, “chocolate to bacteria.” (especially pathogenic bacteria). Those bacteria feast on tryptophan, producing indole groups that cycle back to an iron-toxic liver and generate indoxyl sulfate. Colitis, Crohn’s, colon cancer — the connection writes itself once you see the mechanism. The gut isn’t just a digestion tube; it’s ground zero for copper-iron dysregulation.

🩸 Functional vs. Absolute Iron Deficiency

Morley drops a bombshell: he doesn’t believe absolute iron deficiency exists outside of hemorrhage. The rest? Functional iron deficiency — iron trapped in tissue, unavailable for recycling, while well-meaning doctors prescribe more of it. Bruce Ames’ 2005 research showed tissue iron can be 10x higher than blood levels. You’re not anemic. You’re copper-deficient.

☀️ Sunlight, Copper, and the Prism in Your Blood

Is ceruloplasmin the source of the rainbow in our bodies? Morley traces the connection from photosynthesis to plastocyanin⁴ to the light-processing potential of our own blood — and why your Vitamin D protocol might be incomplete without copper.

👩‍⚕️ Women’s Health, Pregnancy, and Tylenol

From his new book chapter to the real story behind prenatal vitamins loaded with iron, Morley connects the dots between fetal liver toxicity, vaccine injury, and why “we were designed to eat minerals and make hormones — never designed to eat hormones.”

On Tylenol: the recent links to rising autism rates miss the root cause. A fetus exposed to iron-loaded prenatal vitamins develops a toxic liver before birth. That liver can’t detox anything — not vaccines, not Tylenol, not environmental toxins. Tylenol, vaccines and other environmental toxins are triggers only, not the cause. The cause is a copper-deficient, iron-overloaded system that was set up to fail from the first trimester.

Then there’s PCOS and endometriosis — conditions Morley ties directly to the copper-iron-oxygen axis. Morley mentioned research from India that measured ferroxidase function against endometrial wall thickness: the thicker the wall, the lower the ferroxidase activity. I found these related studies from China here and here..  Iron accumulates in endothelial tissue, driving estrogen release — and iron and estrogen love to grow things. Endometriosis, fibroids, PCOS — these aren’t mysterious hormonal conditions. They’re oxidative stress made visible, driven by ceruloplasmin that isn’t functioning. The menstrual cycle becomes a monthly battleground between magnesium and iron because the copper general has gone Absent Without Leave (AWOL).

Bioidentical Hormone Replacement Therapy (BHRT) – sigh – Morley mentioned they were still synthetic despite the healthier sounding label.  Shockingly though, he stated that BHRT is no differeent from antibiotics and some pharmaceuticals – it still disrupts ceruloplasmin! The body was designed to make hormones from minerals — not to eat them.  I found this so discouraging and you will see it on my face reacting to this news in our You Tube version.  So many women are getting relief from BHRT.  I will continue to attend RCP Q&As and revisit the chapter in his book, CURE 2nd edition that has the new chapter on women’s health to see what else is possible.  The last thing we want to do is disrupt our Ceruloplasmin (see below for the full explanation) trying to reduce menopause symptoms.  Is BHRT  a cure worse than the disease?  Hopefully there is a work around but at minimum, its safe to say that if you are experiencing menpause symptoms, this might be more of a reason to start the Root Cause Protocol (RCP). 

🧠Addiction, Heart Disease, and Ferroptosis

Addiction

If dopamine synthesis depends on copper-dependent enzymes, and addiction is fundamentally a dopamine disorder, then you’re not looking at a moral failing or a character defect — you’re looking at mineral dysregulation. Simply put – low dopamine = low copper.  And of course blue light toxicity is a contributor to low dopamine in today’s blue lit world.

The Alcoholics Anonymous (AA) founders’ (technically Bill Wilson ( Bill W.) and Dr. Bob Smith) original plan in 1935 was niacin — feeding the dopamine pathway — before the American Medical Association (AMA) shut it down.  Natural dopamine requires copper.  Without it, addiction becomes a biochemical trap. Bottom Line: The 12 steps became Plan B because Plan A (niacin → NAD → dopamine) got shut down by the medical establishment.  We are still thankful for that Plan B; it has helped so many souls in their recovery journeys. 

Heart Disease

Leslie M. Klevay, M.D., S.D. in Hyg., (91 yrs young!) has been studying the effects of copper on the heart for decades and published 200 articles in over 90 journals. The professor emeritus of internal medicine at the University of North Dakota researches the leading cause of death in the Western world — ischemic heart disease.  Since 1973, over 30 labs have replicated his finding: copper deficiency causes cholesterol to rise. The cholesterol isn’t the problem — the oxidation is.  Curious about the copper link to heart disease, here is a background article. on Dr Klevay’s work and another specific to the benefits of hard water for heart disease.

Ferroptosis

And tying it all together: ferroptosis — iron-directed cell death via lipid peroxidation. In a copper-deficient body, iron is the match and PUFAs are the kindling. Several 2024 studies mapped ferroptosis against a stunning array of conditions: neurodegeneration, cardiovascular disease, cancer, addiction-related organ damage. The common denominator? Unregulated iron. The missing element? Copper. This isn’t a single-disease mechanism — it’s the cellular death pathway underlying virtually every chronic condition we’re told is mysterious.

🔬 Beyond the Basics

Morley walks us through the key players in the iron-copper-oxygen axis with the kind of clarity that makes you wonder why this isn’t taught in medical schools:

• Ceruloplasmin — the body’s master antioxidant, a ferroxidase enzyme made by the liver that carries copper in the blood and commands iron’s every move. Without it, iron runs rampant and oxidative stress follows.
• Hepcidin — the negative regulator, a stress hormone produced by the liver and organs throughout the body. Think of it as the SWAT team: when ceruloplasmin isn’t doing its job, hepcidin slams the door on ferroportin, shuts down iron recycling, and sequesters iron away from pathogens. Problem is, hepcidin doesn’t work without copper either.
• Lactoferrin — the iron-controlling protein found in milk, colostrum, and bodily fluids. Morley reveals its critical role in iron recycling and drops a bombshell connection to Long COVID: anyone suffering from it has a copper deficiency. Lactoferrin regulates the recycling — and without copper, the system collapses.
• Ferroportin — the only known iron exporter in the body, found in the intestines, liver, and macrophages. It’s the doorway iron passes through, supported by ceruloplasmin and its cousin hephaestin. When hepcidin blocks that doorway, iron gets trapped.

Summary

Morley Robbins doesn’t pull punches. He calls iron the “#1 element on earth — how could the most evolved species on the planet lose its ability to use it?” He pulls back the curtain on the Wizard of Oz that is modern medicine, and what you’ll hear will reframe everything you thought you knew about fatigue, inflammation, and chronic disease.

Footnotes

1. Indoxyl sulfate – is a metabolite of tryptophan that acts as a cardiotoxin and uremic toxin. It is produced by intestinal bacteria and liver enzymes, and is associated with chronic kidney disease and vascular disease. (Wiki)
2. NAD – nicotinamide adenine dinucleotide, a crucial molecule found in every cell of the body that plays a key role in energy production and various metabolic processes. It exists in two forms, NAD+ (oxidized) and NADH (reduced), and is essential for converting food into energy and supporting cellular functions. (Wiki)
3. CKD – Chronic kidney disease happens when the kidneys are damaged for more than a few months. The kidneys clean the blood by removing waste and extra fluid, which leaves the body as urine. They help control blood pressure and balance salt and minerals. The kidneys also help the body make red blood cells and keep bones strong. (mayoclinic.org)
4. Plastocyanin is a copper-containing protein that mediates electron-transfer. It is found in a variety of plants, where it participates in photosynthesis. The protein is a prototype of the blue copper proteins, a family of intensely blue-colored metalloproteins. (Wiki)
