Hmmm. thanks for the comments and article - I have to say this is largely over my head, but sort of sounds right, if that makes sense. What's your take on colloidal mineral products? I had always avoided them because I read somewhere that they can collect on organs, etc., that it wasn't a natural form. Recently, though, on the recommendation of my naturopath/homeopath, I started taking a product called Super PH Minerals (which I believe is a colloid) made from Fulvic Acid. I've been feeling gradually better since I've been taking it over the past few months, though I am on and off a lot of things, so there are usually too many variables to really know what's helping. One thing I have noticed is my nails are growing like crazy and they're hard, which is not the norm for me. I am assuming that's due to mineralization... ?
