Doses of potassium iodide as low as 50 µg cause me fatigue and tiredness. It should take at least 10x that dose to cause fatigue through the Wolff-Chaikoff effect, where hypothyroidism develops from excessive iodine intake. My thyroid levels test normal and my doctor has been unable to explain it.

Do you take it alone?

50 micrograms of KI? I can't believe that you aren't getting similar small quantities of KI in your diet, if from nowhere else iodized salt which is everywhere. I would expect that some fruits and vegetables would contain quantities of KI in similar magnitudes naturally even without iodized salt.
How do you know these small quantities of KI are causing these issues?

Try eating some dulse(which has a ton of iodine) instead of the supplement and see if you react the same.

The first time I noticed this effect was from taking a kelp supplement with 150 µg of iodine per tablet. It happened again (fatigue and a sleepy feeling) while taking a multivitamin that I didn't realize contained iodine, the amount was 50 µg. I'll try picking up some dulse and report back.

The problem is that you are likely consuming foods that have more than 50µg KI. One gram of iodized salt has 45µg. Even if you don't use iodized salt at home, if you eat out or eat prepared foods you'd usually be getting 1g or more of salt in a meal. And it's not just things seasoned with iodized salt. A cup of yogurt is 75µg. Two eggs is 50µg. Three ounces of cod is about 100µg.
If 50µg of KI can cause that sort of reaction in you, you should be getting this reaction commonly after meals. KI is quite common in many foods, which is good because our thyroids require it.

Same here. Kelp with 300mg iodine makes tired, dizzy and nauseous.

Has it occurred to anyone that there is more in kelp than potassium iodine?

I prepare my own meals and primarily eat green vegetables, fish, chicken, and nuts. I know I'm getting some iodine in my diet, but I suspect the supplementing is pushing me over the edge. I'm going to try eating a gram a day of dulse starting tomorrow.

I take a drop of SSKI (25 mg of iodide, I think), along with some selenium. I don't feel anything. Not to discount your experience, but I have a hard time believing that micrograms will have such a big impact.

I ate the dulse with dinner twice and each time was very drowsy the next day until after noon. Anyone want a bag of dulse?

This happened again and I was able to trace the reaction to a fungal infection, once it was treated I could tolerate iodine again without the somnolence.

Thanks for coming back and clearing it up so people won't worry
