How are you measuring it?
Blood tests 2x per year Quest.
Before deciding on how much iodine supplementation you take It is worth considering where you live and more importantly where your food is grown. As the main source of iodine is from the ocean inland regions (like Switzerland and central US) tend to have very low soil iodine levels whereas coastal regions tend to have far higher levels. The ocean isn’t the sole source of iodine so there will be exceptions to this.
The Japanese as mentioned in this thread have high iodine intake not just due to sea vegetable consumption but also from their regular crops. The UK, another island nation, has no iodine fortification but serious iodine deficiency is rare. However it still may be a shortfall nutrient in pregnant women and with changing diets and soil depletion it may be necessary to start fortifying soon.

My multivitamin has iodine in it. I feel like I’m covered by the 150µg I’m supplementing + whatever my dietary intake is.

Yes, a blood test showed that my Vit D levels were lowish - just in adequate range, whilst taking about 4x RDA. I started taking 5000IU’s (125micro g or 25 x RDA in UK). The blood test after a few months brought me into the optimal range. About six months after that I was at the high end of optimal, so I cut my dose back to 2500IU’s (62.5 micro g or 12.5 x RDA). My latest blood test showed a drop to the low end of optimal. This suggests that for me (although we are all individual) a dose somewhere between the two of these would be best.

I’m in the same boat. Milk/milk substitutes are also fortified with iodine so you’ll be getting more than enough if you have those also.

I am a huge fan or fucoidan which has iodine naturally. I take the Matakana brand. Recently discovered Ecklonia Cava which seems to also help with sleep.

I went down the Dr. Brownstein iodine rabbits
hole about five years ago when I first started getting bad hypothyroid brain fog and fatigue. I tried mega dosing Lugols and it didn’t help, so I stopped.

This is going to go well…

Actually, I think Ryker is not that bad. I’ve ordered liquid Lugol’s iodine. I’ll try 1 mg a day to counter deficiencies.

1 mg is ok within UL

Eh I don’t know. Last I checked, he still thinks things like Fisetin, Resveratrol, and NMN are worth taking

Also seems to act as both an ACE-i* and a CCB, “significantly” lowering BP by vasoldilation. I wonder if its ACE-like properties would interfere with the action of an ARB.
*It turns out that this supplement can induce a chronic cough, a side-effect of ACE-i treatment.

This a test that I didn’t notice before. It was normal so I didn’t think anything about it.
Is this test sufficient to indicate that I don’t have an iodine deficiency, apparently not?
My tests have always been in the mid-normal range, but that might not be a sufficient indicator.
" Yet, in older children and adults, serum TSH is not a sensitive indicator of iodine status as concentrations are usually maintained within a normal range despite frank iodine deficiency.

Thank you! I do find it helps sleep and also it seems to work well as an anti inflammatory. I am just using a cheap brand Swanson. Have not noticed any side effects at all. I have an acoustic neuroma treated 5 years ago by radiotherapy and fucoidan/ecklonia cava was recommended to me by a Prof in oncology. Here is a small extract from a recent article: Ecklonia cava effectively inhibits tumor angiogenesis . The mechanism is mainly through PI3K/AKT/mTOR and Ras/ERK signaling pathways to block the production of VEGF protein, and then block the activation of VEGFR-2 signaling pathway, thereby effectively controlling the process of tumor angiogenesis. My MRI over past 5 years shows the lesion has halved in size. It works also on GABA a bit like diazepam.

There is a test a doctor helped create when he found there were no actual tests for finding optimal amounts. The test basically works by taking large daily doses of iodine and then measuring the urine excertion amount. So its very similar to a curshing syndrom urine test with 24hr collection. Aparently its like 99% if not used is excreated in urine, so thats the basis of the test. I think the amount orginally used was like 20-50mg daily for a week or 2 then a daily 24hr collection. What was found was the body daily uptake once steady state was reached was 6-10mg. This is astronomically more than any RDA amount. Not surprising as the RDA was set using an adaption of the minimal amount needed for livestock to prevent serious fertility and birth mortality a couple centuries ago. I do not think actual human studies were done before the rda was set back WWI?
I will try to find the article and I think there is a youtube video about the topic as well.
I take 6 mg per day. I just add to my two ½ gal bottles of flavored water (3mg each) I drink thru out the day.
I also add my potassium bicarbonate (adds a bit of fiz to my drink which I like plus gets me a gram of potassium. I add a mixture of solible fiber as well. One is the mod citrus fiber the other is IIRC is called gentle gut fiber? ( I will check.) Its a mix of like 6 different soluble fiber. It adds up to about 10g fiber per ½ gal. It completely disolves and no noticable change in the water viscosity. The iodine adds a very slight taste but its lost in my tangerine flavored water flavoring. Thats where all my fiber and potassium iodine supplementation is. As I eat keto I am trying to double dip in terms of gut bacteria from the benefits of both. As the fiber is gradually consumed thru the day I have not noticed any gas or other neg sides. It also ensures plenty of fluids with the fiber. Very regular, easy, well formed, BMs
I will try to look for the idoine testing article tomorrow when I get home. I think there is a book published on the tpoic as well. I know there was discussion about the conflict with flouride and bromate? The latter is still added to some flours and bake products. Use to be used far more widely apparently. I think the idea is to take higher levels of iodine to gradually displace and excrete the flouride & bromate. And of course to stop any flouride intake.
I do know a few different municiplaitiies citizens in various states have sued and won to have flouride removed from the water supply under the fact no proper health benefit/harm testing was ever done. I know I saw this whole thing in a youtube video from dr that hosts guests on.

I’ve been doing iodine for better part of last 15 years. But I thought I’d read back then that it is a good idea to load up for a period and then relax, so I usually do 20mg daily for about couple months per year. Other than the fact I’m in excellent health couldn’t tell if it’s done anything good since I usually take about 20 other supplements and couldn’t pinpoint exactly which is giving most benefit. So far so good never been sick and never been to a doc in last 30-40 years, last 20 of which I’ve taken many, many supplements. In other words it could be just luck or perhaps my supplements might have kept me disease free so far.
I had to explain to my primary care doc a TSH of 0.314 [0.450 - 4.500] uIU/mL and Free T4 1.20 [0.82 - 1.77] ng/dL. likely as a result of the 0.5 mg iodine daily. It raises the issue of what would be a normal reference range of TSH in a population taking more than the alleged MDR of iodine, which I think might be too low AT 0.150 mg.

Did you have your T3 or reverse T3 tested as well?
Since no clinical evidence of sick euthyroid or hyperthyroidism have not had it checked.
