But if you kept recycling urine by urinating and drinking it multiple times, wouldn’t those minerals eventually build up until the urine was no longer safe? Over several days, your urine would become saturated with minerals. And drinking it would really tax the kidneys, whose job it is to flush unwanted minerals and toxins from the body. Drink urine long enough and you may go into kidney failure. On a related note, you may have heard that in some cultures, urine is used as medicine. There’s no hard evidence that urine has any curative powers, which doesn’t mean it has none. But urologists tend to believe that whatever healthful powers drinking urine has would be negated by toxic buildup in the kidneys.
