So, how does your body generate creatinine? It starts with creatine, which is mainly synthesized in the kidneys, pancreas, and liver. It simply stays in the blood until reaching the kidneys, where it’s filtered and eliminated through urination.

Creatinine itself doesn’t have a specific physiological function-it’s just a waste product. Creatinine is a natural byproduct of muscle use, caused by the breakdown of a chemical called creatine. What is creatinine?Įveryone has certain serum creatinine levels in their bloodstream. While it might be the last thing you think about while exercising, your blood creatinine levels can be a key indicator of your renal health and kidney function. When your muscles break down during exercise, they slowly build back up, increasing muscle mass, but this process also releases waste products into your blood, primarily creatinine. But there’s a whole lot more going on under the surface. Like most people, you’re acutely aware of how physical activity makes your body feel- the breathing, sweat, and heat. And when you’re done, nothing feels better than a warm shower, a cold glass of water, and a seat on the couch. You’re breathing fast, and your muscles are on fire. You’re 10 minutes into your afternoon jog, powering through your daily exercise routine, or biking around the neighborhood.
