Thanks for you response a month of so ago. Did not get it until now. You seem very much on target but I have to study why you said. I have been very wiped out and just got my results back from Flechas, spot and loading. The loading and saturation are both low. Still have to talk to MD about it. Have gone back to 4 Iodoral per day but not much increase in energy. I don't know where I would have gotten the heavy metals, though.
