The War on Iodine. Part 1 — The Chemistry Catastrophe

We found multiple hit pieces on iodine and include such claims that iodine is a “synthetic lab creation” – a dangerous industrial chemical that was “invented” rather than discovered.
We are also told it is not a natural nutrient and is actually an explosive by-product being sold as medicine. This is nonsense. Not nuanced disagreement or a difference of interpretation, it’s just flat-out wrong.
If you’ve read our recent article “Controlled Demolition,” you’ll already know the pattern. But the iodine claims deserve special attention because the chemistry is so fundamentally wrong that it actually becomes dangerous, to the point where people may stop taking a nutrient they genuinely need. That’s not health freedom, it’s just a different kind of fear-based control.
So let’s examine these claims, starting with the chemistry.
Discovery vs. Invention – Getting the Basics Wrong
An article on the Medicine Girl Substack claims:
“Bernard Courtois… added sulfuric acid to ‘separate’ the nitrates. Really? You added a chemical, which makes a new chemical, not isolating and separating things found naturally… That was iodine. It was not discovered in nature. It was created in a chemical reaction under military demand.”
This reasoning would mean that oxygen was “invented” when Joseph Priestley isolated it in 1774, or that magnesium was “created” when Humphry Davy first extracted it in 1808.
Iodine existed in the seaweed ash before Courtois did anything. The sulfuric acid didn’t create iodine – it released elemental iodine from the iodide salts already present in the kelp. This is isolation, not invention.
When you squeeze a lemon and release vitamin C into your water, did you “create” vitamin C? Of course not. You released something that was already there.
Courtois discovered a method to isolate iodine. He didn’t conjure it into existence from nothing. The iodine was in the seaweed because the seaweed had concentrated it from seawater, where it exists naturally as iodide ions.
This isn’t semantics. Understanding the difference between discovering an element and inventing a compound is foundational to evaluating everything else in the article.
The “Synthetic” Lie – Extraction Method Doesn’t Determine Molecular Identity
The article makes a significant point about how modern iodine is extracted from Chilean nitrate mines and oil brines using “industrial acids and reducers,” implying this makes the resulting iodine fundamentally different from what’s in seaweed.
Here’s what she doesn’t mention: Chilean caliche is an ancient Palaeolithic sea sediment from the Atacama Desert. The iodine in those deposits got there the exact same way it gets into seaweed — from the ocean. It’s just been sitting in the desert for millions of years. The Japanese source is underground brines — ancient salty water trapped beneath the earth which is naturally rich in iodide ions. These aren’t factories manufacturing iodine from scratch, they’re extracting it from places the ocean left it.
This is flawed logic we’ve seen before with other minerals.
The molecular reality
An iodide ion is an iodide ion. Full stop.
Whether it came from:
- Kelp harvested from the Scottish coast
- Chilean saltpetre deposits
- Japanese underground brines
- Or Bernard Courtois’s seaweed ash in 1811
…the iodide ion (I⁻) has the exact same molecular structure, the same atomic weight, the same chemical properties, and the same biological function.
By this logic:
- Magnesium from the Dead Sea is “natural” but magnesium from undersea brine wells is “synthetic”
- Calcium from crushed oyster shells is “real” but calcium from limestone deposits is “fake”
- Vitamin C from acerola cherries is “good” but vitamin C from fermented corn is “dangerous”
Do you see the problem? The source doesn’t change the molecule.
Yes, commercial iodine production uses industrial chemistry. So does literally every mineral supplement you’ve ever taken. They are extracted, refined and purified. That’s not creating something synthetic – it’s isolating something that already exists in nature.
What’s Actually in Lugol’s Solution?
The article makes dramatic claims about Lugol’s being some sort of industrial Frankenstein creation. Here’s what it actually contains:
Lugol’s iodine is:
- 5% elemental iodine (I₂)
- 10% potassium iodide (KI)
- 85% distilled water
When you mix elemental iodine with potassium iodide in water, you get a solution containing:
- Iodide ions (I⁻)
- Triiodide ions (I₃⁻)
- Molecular iodine (I₂)
This provides both forms the body uses:
- Iodide for the thyroid gland
- Molecular iodine for breast tissue, prostate, and other organs
The potassium iodide serves two purposes:
- It makes the elemental iodine water-soluble
- It provides additional iodide ions
The molecular iodine and iodide ions in Lugol’s are chemically identical to what you’d get from eating seaweed. The kelp doesn’t hand-craft special “natural” iodine molecules that are somehow different from “laboratory” iodine molecules.
When you eat kombu (kelp), your digestive system breaks down the iodine-containing compounds into… wait for it… iodide ions. The same iodide ions in Lugol’s.
Your thyroid cannot tell the difference. Because there is no difference.
The Gunpowder Red Herring
The article makes repeated dramatic references to saltpetre, explosives and war, as if this somehow taints iodine forever.
Yes, potassium nitrate (saltpetre) was used in gunpowder. Yes, the same industrial processes that produced nitrates also yielded iodine as a by-product. Yes, there’s a shared element (potassium) in both compounds.
So what?
Potassium is the seventh most abundant element in the Earth’s crust. It’s in bananas, potatoes, and your body’s cells. Are bananas tainted by association with gunpowder?
This is guilt by chemical adjacency – a logical fallacy dressed up as historical investigation.
By this reasoning:
- We shouldn’t eat salt because sodium was used in chemical weapons
- We shouldn’t breathe oxygen because it’s used in rocket fuel
- We shouldn’t drink water because hydrogen is explosive
See how absurd this gets?
The Anaphylactic Shock Scare
The article claims: “There’s a reason people go into anaphylactic shock from so-called iodine exposure.”
This deserves clarification because it sounds alarming, which it’s meant to!
- Iodinated contrast dyes used in medical imaging contain complex organic compounds with iodine atoms attached. Reactions to these are typically to the carrier molecule, not the iodine itself.
- Shellfish allergies are to proteins (tropomyosin), not iodine. This myth has been thoroughly debunked in the medical literature.
- True iodine/iodide allergy is extraordinarily rare – so rare that many researchers question whether it exists at all as a distinct entity.
What people actually react to:
- Carrier compounds in contrast agents
- Shellfish proteins
- Preservatives in iodine preparations
- Rapid detox reactions when bromide is displaced (not an allergy – a healing response)
Conflating these with “iodine allergy” creates unnecessary fear around an essential nutrient.
This article has constructed a narrative on a foundation of chemical misunderstanding. The claims demonstrate confusion about:
- The difference between discovery and invention
- The difference between extraction and creation
- The difference between molecular identity and source material
- The difference between elemental iodine, iodide ions, and iodine-containing compounds
Everything that follows from this broken foundation needs equally careful examination.
In Part 2, we’ll tackle the confusion between thyroid medications and iodine supplementation – because apparently stopping Synthroid is being presented as evidence against Lugol’s solution.
Spoiler: These are completely different interventions.

A book to consider:
The Iodine Crisis: What You Don’t know About Iodine Can Wreck Your Life Paperback – Illustrated, Jan. 2 2018 – by Lynne Farrow (Author)
Thanks to environmental pollutants Iodine deficiency has become a worldwide epidemic. Everybody knows pollutants cause cancer. What they don’t know is that these pollutants cause a deficiency that can make us sick, fat and stupid. Iodized salt–supposedly a solution to iodine deficiency– is actually a nutritional scam which provides a false sense of security. The Iodine Crisis explains how we became so deficient, then shows the time-tested solution to reversing many conditions. Lynne Farrow reveals how she and thousands of other patient-activists changed their lives by researching and using iodine. Frequently Asked Questions cover everything you need to know about iodine. The proof of iodine’s benefit is demonstrated by the dramatic case studies shared in this book.
