The iodine method in Gut and Physiology Syndrome begins with iodine painted on the skin. Dr. Natasha Campbell-McBride calls this “iodine paint” and uses the time the brown color remains as her observation. Her chapter also describes when she considers oral supplementation and the limits of its coverage.[1]
Here is the method as the 2020 book presents it. Keeping the patch instructions, tablet strengths and oral-dose decisions separate makes the passage much easier to follow.
The Patch and Its Timing
The book names Lugol’s iodine solution, available in concentrations from 2% to 15%, and a patch no smaller than the person’s hand. It does not select one of those concentrations as the required strength for everyone.[1]
| Observation | The Book’s Interpretation |
|---|---|
| Brown color remains for about 24 hours | The average time described when there is no iodine deficiency. |
| Brown color disappears in 12 hours or less | The result the author interprets as iodine deficiency. |
The brown patch is the observation used in this method. It does not give a measured blood or urine iodine concentration. The table reports the author’s interpretation; it is not a conversion between skin color and a laboratory result.
The Nightly Routine in the Book
- Paint the hand-sized patch at bedtime.
- Check it the next morning. The book interprets a completely vanished patch as a need for more iodine.
- Continue the nightly routine described in the passage.
- Use different areas of skin. The author specifically warns that repeatedly painting the same place can cause irritation.
These instructions are described for children and adults. The source’s skin-irritation point belongs with the method, rather than being left out because the author also describes iodine paint as a safe supplementation approach.[1]
Oral Supplements Are a Separate Step
If the patch still indicates deficiency after some weeks, Campbell-McBride says it may be time to consider oral iodine. She names Iodoral, an iodine/potassium-iodide product, and lists tablet strengths of 12.5 mg and 50 mg. Those are the two strengths named in the book, not a universal starting prescription.[1]
Her instructions are to start with a smaller dose, use it for a few weeks while continuing the paint observation, and adjust gradually. She does not give one fixed milligram starting amount for every reader in this passage.
The book also mentions Lugol’s drops in water, but says the different oral doses become complicated and are beyond its detailed scope. It explicitly says that iodine can be overdosed and that higher doses require research, an experienced practitioner and professional supervision.[1]
Write down concentration, product form and units separately if you are discussing a product. A percentage on a solution and milligrams on a tablet describe different things; neither tells you an oral drop dose by itself.
Where Seaweed Enters
The official thyroid FAQ describes seaweed as the long-term food source once someone is on Full GAPS and digestion is functioning well. It names kelp and knotted wrack, Ascophyllum nodosum, and describes gradually increasing the amount while continuing its skin observation.[2]
Keep that digestive-readiness condition attached to the recommendation. Seaweed being named here does not make it an automatic early Intro addition. The GAPS food list helps you place the food advice in the wider diet.
Keep the Source Answers Distinct
The older FAQ uses disappearance within 24 hours in its answer. The 2020 book gives the more specific contrast of a 24-hour average and disappearance within 12 hours or less. The patch table above follows the newer book.[1][2]
The FAQ says the author has no experience with Dr. Brownstein’s iodine protocol and cannot comment on it. Its recommendation of iodine paint should not be turned into an endorsement of that separate protocol.[2]
The thyroid FAQ also says to continue thyroid medication during the programme if it has already been started. The iodine passage is not a replacement medication schedule. For the wider thyroid context, use the supplement overview alongside your existing thyroid plan.[2]
Make the Notes Useful
Keep the product label, patch time, observation time, skin location and any irritation together. If oral supplementation is being considered, put that on a separate line rather than treating a disappearing patch as a milligram calculation.
The Supplement Introduction Tracker is listed in my WFLI Shop.
For other supplement questions, return to the GAPS supplement guide. It separates food, oils, probiotics and targeted vitamins or minerals so that the iodine instructions do not become a general supplement list.
