L-ornithine is a popular ingredient in dozens of exercise supplements used to increase power and endurance during workouts. Despite its widespread use, many athletes still don’t know exactly what L-ornithine is and why it works.
What Does L-Ornithine Do?
While the chemical details are complicated, the end result of L-ornithine is increased urinary output. At first glance, more bathroom breaks doesn’t seem like it would improve exercise, but L-ornithine isn’t just acting as a simple diuretic.
After it’s processed in the organs, L-ornithine binds to excess ammonia and nitrogen in the bloodstream, transporting it to urine where it can be disposed. The result is lower ammonia and nitrogen levels in the body.
During intense, long-term exercise, ammonia buildup can become a problem, inhibiting energy production and causing fatigue. By flushing out these built-up compounds, L-ornithine allows muscles to keep working, improving your endurance and workout quality.
Studies examining L-ornithine show that it is an effective, safe way to decrease ammonia concentrations during workouts of more than 45 minutes, with no adverse side effects.
Unfortunately, we aren’t sure about other benefits of L-ornithine. The bulk of research has focused on its effects on the urea system. While long-term studies on muscle tissue are necessary, evidence solidly shows L-ornithine at least boosts endurance and reduces fatigue.
Bringing It All Together
When looking at the immediate, simple benefits L-ornithine provides, its popularity becomes clearer. It’s an effective, fast, and natural way to get rid of chemical waste during exercise and extend muscle power.
L-ornithine is a great ingredient: simple, effective, and safe. We expect it to continue to grow in popularity as more research is conducted.
