Supplementing iodine will increase TSH and render TSH testing useless, Free T3 against Reverse T3 will provide more useful information.
Huh? Every single site I visited recommends taking iodine and selenium to keep thyroid healthy. Like: “If your TSH is high, that might be because of iodine and selenium deficiency, you eat them and it will lower, you’ll be cool.”
But I’m not competent with how thyroid, iodine, and selenium wire together. Could you show me a few links to read, so I can start learning about this topic? What should I do then? Should I cancel this supplementation?
I already had been taking L-thyroxine until April 2018, 25 mcg daily, it had mild effects, if any: maybe higher libido, maybe higher anxiety, but was able to keep TSH at 1.7.
And on 50 mcg I felt like my head gonna explode.
I never stated iodine and selenium wasn’t healthy, I said it renders TSH testing useless.
In areas of iodine deficiency, a sudden increase in iodine intake is associated with transient hyperthyroidism. Recent studies demonstrated that long-term thyroid function of subjects who experienced both iodine deficiency and iodine excess during childhood tended to be abnormal despite optimization of their current iodine intake. In foods with high iodine contents, which can result in thyroid dysfunction in some susceptible individuals.
