hi i also have not extremely high levels of barium but elevated urine barium levels my family doc found this. i dont know where its coming from but i have heart problems[myocarditis]. which the barium may be contributing too. i dont know where its coming from but i have found out that edta, dmsa, and ip6 with inositol could all possibly chelate the barium out of your body. definitely take potassium as the barium raises blood pressure. i have found very little help when asking naturopaths and doctors about ways to get barium out of the body. but if u try chelation, do tiny amounts like in cutler cause i have tried edta, and dmsa and both inflammed my spleen and heart so badly[they are already inflammed], i couldnt keep doing either of them but i tried 250mg of edta once and 300mg of dmsa which with the cutler protocol u should only take 15mg every 4 hours of dmsa a day to start which is under 100 mg much safer at small doses to start.
