Are you talking seriously about 5g, which is close to a teaspoon of dry potassium Iodide
powder per day?
remember, there's grams -
1 gram = 1000 milligrams = 1,000,000 micrograms
Try searching for posts on borax (boron) in the Iodine
VWT forum here on CZ, it's often the cofactor that helps give Iodine
that extra punch .
