Is UT dangerous if you are detoxing metals and mercury? Does mercury and heavy metals use the renal exit- yes I think it does? I am not really experienced in this UT, so i am going to get the book: Excitotoxins, the taste that kills by Blaylock MD. Does anyone not like this book? I think i should give it a try since I believe God has prepared us to remain healthy without expensive manmade products. I spend so much money on herbs, minerals, homeopathy, organic everything, electrical medical devices, etc... If UT works, it will save me some money too. It seems UT is very specific for each individuals problems. Please post your sucesses, I love to hear it! Stay happy and healthy!
