One of the things you'll see repeated here is that when you take a form of Iodine that includes elemental Iodine besides or excluding iodiDe, you need to take it on an empty stomach with water only...like first thing in the morning.
If you want the Iodine part to be fully advantageous, take it with water only. 4 ounces is what I read about (way back when); I believe it's because of its chemical interaction with the digestive nature of the stomach.
