Re: are we talking 600mcg?

"it's actually 600 mg and not mcg, unless I got something wrong."

- Not that I know of :). I was not familiar that this type of Iodine was to be found in mg-sizes.
I have tried one type of Iodine in addition to Lugols; that was the "detoxified" iodine, (also after a Cayce recipe If I recall right.)
This type of Iodine did nothing for me, same with kelp.

I believe the most important thing is to find out of the dosage and type of iodine YOU have benefit of.
300 mg is the most I ever took in one day, but one day I will go for a gram, just for the fun of testing.
