Also know that Millions are drinking fluoridated water and this too is causing havoc on our thyroids. I bought my water for a long time and then stopped due to covid and shopping and too much plastic, so now am drinking tap public water which is fluoridated. I also take 1.83mcg of iodine daily and also Naturthryoid thyroid med. I don't like Synthroid.

Soy is a killer to our thyroids, I was so fatigued at one point yrs ago and my chiro tested me and found the culprit was soy milk, bad stuff. I got off it pronto.
There is so much to learn about the importance of the thyroid and depression, fatigue and so much more health issues when our thyroid is not working.
