Lugols Solution is part of The Iodine Protocol, and is a type of iodine that has been consumed since 1829. It is a deep red-ish/brown color and smells a bit like bleach to some people. I personally think it smells like pool or tap water.

Lugols Recipe:

Lugols was first produced by a French physician Jean Lugol in 1829. Originally it was only produced in a 5% strength. But today it’s made in various strengths including 2%, 5% and even 46% etc. This % just makes it easier to adjust the amount of iodine in each drop.

What makes up Lugols?


A naturally occurring element essential for human growth and metabolic function. Its atomic number is 53 and its chemical symbol I. Elemental iodine is two iodine atoms bonded together, it’s molecular formula is I2.


The ion state of iodine, occurring when iodine bonds with another element, such as potassium iodide in Lugols. In this form, iodine can be ingested or applied topically.

Other names for Lugols

  • Triiodide
  • Thiodine (Miss Lizzy’s)
  • “Strong” iodine
  • Aqueous iodine

Why does Lugols contain two types of iodine?

When we consume both forms, our body makes use of them in different areas. Our thyroid seems to enjoy Potassium Iodide form whereas breasts, ovaries and prostate seem to prefer the Iodine(I2) form.

Lugols is most commonly used

2% Lugols is the most common Iodine for beginners.

The only other commonly recommended formulation of iodine is SSKI because it is clear, making it a bit easier to apply transdermal. SSKI is Super Saturated Potassium Iodide, and potassium iodide is one of the ingredients of Lugols.
