Even Edgar Cayce , back in his day, told people to take their Iodine drops in 4 ounces of water only, on an empty stomach - first thing in the morning, 1/2 hour before eating...and if you take it twice a day, the 2nd time is about three-ish in the afternoon. Again, in 4 oz of only water, on an empty stomach.
There can't be anything else in the stomach, to interfere with the process of the absorption of the iodine, and for any chemical processes our body needs to do with that Iodine for any priorities the body needs from said Iodine on any given day of consumption.
I know in the very very beginning of my own supplementation of iodine, my heart was dealt with first and foremost.
Yeah, I'd call that a priority. Your body is quite intelligent, given the right tools to heal itself...and I needed iodine.
My heart was not exactly functioning too well. Beating too slowly, with severe palpitations and arrythmia, it caused some scary fainting and near-fainting episodes for me for most of my life.
Within the very first week or two - since beginning iodine supplementation - my heart has been just fine!
