I had to go over 50 mg of Iodine to notice much difference; I was on lower dosage for half a year before I decided to go over 50; a little happened before 50, but most happened after going up to 60-80-100mg a day.
Less bleeding, less cramping, less clotting, no FBD.
The big bleeding disappeared in just a couple of months, the other took 4-5 months.
