Look up Iodine deficiency.
I know I’ve not got an Iodine deficiency. We eat a lot of seafood here on the Gulf Coast..................
I know a TON about iodine supplementation. I love iodine. I don’t believe it will cure tinnitus though as I have that and I take at least 50mg per day.
You can’t get enough iodine in food because of the toxins we take in that compete for iodine so you really have to supplement with it and you have to take mgs not mcgs
