Thank you for adding that you are drinking the 8 glasses of water! It is not common but does happen occasionally for some people to have a peculiar odor in their urine. It does not last. The process of cleansing is moving out accumulated compounds. This means smelly urine, stool, even sweat, can temporarily let us know the cleanse is working. Color changes are common.
Other possible causes for urine that smells strong or "bad" include eating asparagus or other foods rich in natural plant chemicals that we break down and excrete in the urine. If you are not experiencing any pain, elevated temperature, or feeling unwell, you can expect your urine to return to normal (or better) in a few days. Otherwise, discontinue the cleanse and see your doctor, just to play it safe. And please, drop us a line to keep me posted.
Sending best regards.
