      Some of it is urea and some other is bilirubin – both yellow.

      Urine is basically water with dissolved waste material from what you have been drinking and eating.

      Your kidneys process and filter blood so that water, sugars, vitamins, amino acids and other vital substances are put back into the bloodstream so your body gets the benefit.

      They also eliminate things your body does not need like urea from protein digestion and creatinine from muscle breakdown. Also eliminated is urochrome, which is a yellow pigment that comes from the processing of dead blood cells in the liver. The urochrome gives the urine a pale yellow color.
