Ever wondered why pee is yellow? Turns out, it’s not just about how much water you drink. There’s some seriously cool science going on behind the scenes.
The Breakdown:
-
Red Blood Cells: Our bodies are constantly recycling red blood cells. When they get old, they’re broken down, and one of the byproducts is a molecule called heme.

Couldn't live without this app anymore. Perfect to time my run for another glass of wine or two. Works great with my smart watch.

Urobilinogen’s Exit: Urobilinogen makes its way to your kidneys and leaves your body as the yellow color in your urine.
Fun Facts:
- Newborns and Jaundice: Newborns don’t have the bacteria that produce bilirubin reductase, which is why they’re more prone to jaundice.
- Poop Color: Another byproduct of bilirubin breakdown, stercobilin, is what gives poop its color.
There you have it! The next time you use the restroom, you’ll have a whole new appreciation for the science behind your pee.
Creator and developer of the RunPee app. When something doesn’t work right in the app it’s pretty much his fault. 🙂
Aspiring author. Would like to finish his “Zombie Revelations” trilogy if he could break away for working on RunPee and the cottage he’s building for RunPee Mom.
