I've been practicing UT for several years through all sorts of
conditions. I can tell by the taste of my urine what's going on with my
body - and what I ate that I shouldn't have. Toxins including heavy metals
exit the body through the liver. I eat lots of raw garlic which also
removes toxins/heavy metals from the body - been doing that for years.
You get many more contaminates from tap water than you do your own
urine. Thanks for the concern, but please don't worry.
