I woud like to find a test I can order to be sure I have pyroluria. I have been supplementing with zinc, p5p, biotin, manganese, and copper and have improved but wish there was a sure-fire way to tell if I am getting enough of each of these supplements. Is there a kit I can order online that help with this? Also, I ordered some "zinc tally" which is basically a liquid zinc solution you put in your mouth. It says if you can taste it then you have sufficient zinc levels and if you can't you are probably zinc deficient. I tried some today and I'm not sure what I'm tasting, the zinc or the sulphate portion. I know I'm sensitive to sulfur compounds and it is zinc sulfate. It tasted pretty strong. Does this mean I should stop supplementing zinc at high levels? I'm currently taking anywhere from 120-240 mg of zinc picolinate a day. I still have very bad sensitivities and allergies borderlining on anaphylaxis. Maybe I need more p5p? Where's the pyroluria experts at ?
