Hello hoping someone can help as worried! I’m in the middle of hormone testing and received the following result on Urine Iodine. Can anyone explain why it’s so high?

Info: on Nature Thyroid for low T3 (non autoimmune), not supplementing or anything.

I'd look through everything you consume. Carefully.

Many products made in Poland, Germany and some other countries are made with iodised salt.

Dairy can contain appreciable iodine - especially if they still use iodophore teat disinfectant. (Some have switched to chlorine-based disinfectants.)

And how much Nature-Throid do you take?

Hi I saw you are from Ireland this made me think of Irish Moss - which is a seaweed so will have a high iodine content if you consume it

Also, if you’re taking T3 then your thyroid isn’t making hormones. The thyroid gland is the main user of dietary iodine, so you’re likely weeing out most of the iodine in your diet.

Caveat: not a doctor, nutritionist or anything like that, but it makes sense to me.

Is this spot testing where it is just done from one random sample? if so I have read somewhere these tests are very inaccurate. The iodine loading test is the only accurate one where urine is collected over 24 hours.

Yes just one spot test

If you are not eating an iodine rich diet then it is not an accurate presentation of your body iodine levels. The spot test will only tell you what the kidneys have decided to dump at that moment it time. Some people take 50mg+ iodine a day and still show up as insufficient on the iodine loading test which is a 24 hour sample.
