Thanks for the advice! I've never had any luck with Silver. It is very expensive, so in order to really take a lot (like several TBS a day) would cost a ton of money. I know some people make it themselves, but doesn't the machine cost several hundred dollars? I've just never found a way to take a lot of silver affordably, and taking small amounts hasn't helped me.
I already have a lot of Iodine, so that would be cheap and easy to try!
