I already taken selenium, at least 400mcg but I usually take 600mcg. And I am already taking L Tyrosine.
I've scrounged the internet for information on instances when goiter is caused by something other than Iodine deficiency but I've been unable to find anything aside from some kind of infection but I would think if that was the cause Iodine would help with that anyway. The swelling in my neck was first noticed when I was about 3 years old, I'm 31 now so I would think I have A LOT of healing to do still. My two nieces who are 2 and 4 also have puffy swollen necks but my sister already started them on Iodine and theirs has improved already....
I've been gluten free for many years now, grain free and eat limited amounts of dairy and sugar. I also do not eat soy which causes a lot of digestive problems for me and also headaches.
