From what Ive read, potassium iodide is best, but Lugols Solution and Iodoral mix two versions.
It appears we need iodine, but in the US, the Upper Tolerable Limit is 1,100 MICROgrams or 1.1 MILLIgrams a day, according to resources Ive seen.
those are both actually iodide AND iodine, which is crucial to get the benefit.
that’s not true. I take upwards of 50mg per day. 1100 mcg’s is only 1.1mg. That’s a VERY tiny amount. Essentially ineffective.
