Quinthius is correct in one sense but one must consider the laws of transmutation and the bodies abilitie to decode the blueprint that urine expresses , thus allowing the body to read these imbalances or deficencies and transmute certain elements into those that are needed and allowing the body to return to its natural state.
If you are not absorbing the necessary nutrients through digestion the excess water in the blood will express this in the urine and when ingested these particular elements adjust and transmute accordingly into a highly usable form!
