What hammock said. They are right in that heavy metal deposits are unlikely to show up in a blood test. That's the root of the problem in that they are embedded in tissue in vital organs. To get them out requires a combination of many different enzymes to break down biofilms and then EDTA to bind to the metals so the body can remove them. In my case it was a matter of hit-or-miss trial and error. I have basically gone through hundreds of self experiments to find the cause of idiopathic hypertension and heavy metal chelation was the second thing I found that made notable improvements. The first was also related to metal or metalloid, a lack of it in fact. I needed selenium and a handful of other elements to fix the thyroid. I removed myself carefully off two BP meds including a very dangerous one and moved out of the red into the amber by USA standards. With time I will figure out the other causes and get into the green.
