good god, what are you talking about? potassium constipate?
some facts.
potassium is a critical and major nutrient. the federal death administration says the Ridiculous Daily Amount of potassium is 4.7 GRAMS. PER DAY. and for a 180 pound adult male its probably closer to 8 grams.
so how is two milligrams of potassium per drop of 5% Lugols having any effect whatsoever?
pro-tip. it aint.
my guess is that most people are so sick for so long they have no idea what good health feels like and it scares them so they retreat to whatever lifestyle it was that made them sick in the first place.
