My recent blood level of lead is slightly higher. The only change since the last test is the uses of hand sanitizer (which was supposed to be clean) and walking daily in a suburban tree lined area. When I wrote the company they say none of their products has more than 3 parts per million of any metals in them. I have no idea how much that is or how much it would take to raise a lead level. I only use the sanitizer 2-3x a week, right after shopping/errands etc. when I get in the car so I don’t forget or touch my face before getting to a sink. It is not everyday. Can you comment and give me some items that I may not think of that could cause a lead level to rise? i do not smoke, drink or use make-up. I take Dr. Amen’s suppliments Brain/ Body.Thanks!
