Thanks for your reply. I'll buy the glutathine and try it out. I'm actually looking for a product that can safely bring out the redistributed metals (if any, caused by the cilantro) but NOT for a long term heavy metal removal (he's on a treatment for the cancer cells), as my dad does not have any fillings in his mouth. Would glutathine help with this?
He has some citrus pectin with him. Does it help in this situation?
