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.

What people are saying
about the RunPee app.Single best investment
By and far best investment Ive made. I used to drive my husband nuts because Id be a fidgeting mess the last half hour of the movie trying not to miss important parts. Now I just turn this app on and *bam* I can actually focus on the movie the whole time. Even puts alerts to my watch so even better. Also I can guarentee all the 5
reviews arent fake as one person accused - its just that so many of us movie-goers had the same problem and this fixed it. Yes, it is paid but jeeze its expensive to keep watching movies and updating an app for every movie. And if you read more about the creator he mentions he has several people contributing - so yeah its paid but omg worth every cent. 10/10

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.
