:scratch: 6000-30,000mg???
That would be an incredible amount to take. Good research though. So far my urine looks fine. No Nausea, ringing in the ears and no upset stomach. If act, quite the opposite has been true.
But how much of the Uva Ursi is in one serving. I couldn't tell because the actual amount is hidden in the 12 g "proprietary blend." That should trouble you a little bit. It reminds me of the "coral calcium" scam several years ago.
