One option is to paint the Lugols on your breasts, for the elemental. Aveola area in particular.
Then take your Lugols internally as much as you like diluted in juice, tea, or water with vitamin C in it.
Heartburn or other stomach upsets after supplement; is a strong signal from your body. Too consentrated, or the stomach acid may be to weak (not so much to do with the iodine, but the other supplements) No need to stop the lugols, just change how you take it.
Taking Iodine / Lugols in a capsule like this, is not for everyone.
