Dark yellow urine is a sign of dehydration. Your urine is dark because your kidneys are doing what they are supposed to do when you are dehydrated: conserving water by making less urine. If this is the case, drink more water â eight 8-ounce glasses each day.
The yellow comes from urochrome, a substance generated by the breakdown of hemoglobin, the oxygen-carrying protein in red blood cells. A surprising number of things can affect the color and odor of your urine. The most common ones are harmless and temporary, including foods, vitamins, and certain medications.
