L-Ornithine — Ammonia Removal & Recovery
What is ornithine and how does it support recovery?
Ornithine is an amino acid that plays a central role in the urea cycle — the process through which the body removes ammonia produced during protein breakdown and intense physical exertion. High blood ammonia levels cause fatigue and reduce performance. Ornithine helps accelerate ammonia removal, supporting both post-workout recovery and sleep quality, as it stimulates growth hormone release during deep sleep.
Frequently asked questions about ornithine
Ornithine accelerates ammonia removal from the bloodstream through the urea cycle. Intense training raises ammonia levels, causing fatigue and muscle exhaustion. Additionally, ornithine stimulates growth hormone release during sleep, which in turn promotes muscle recovery and tissue repair.
For recovery support, 2-6 grams of ornithine is recommended before bed on an empty stomach. For training performance, you can take 2-3 grams 30 minutes before training. For growth hormone stimulation, the nighttime dose is most effective. Start with 2 grams and increase based on tolerance.
While both participate in the urea cycle, their primary roles differ. Arginine is the main precursor to nitric oxide (NO), which dilates blood vessels. Ornithine specializes in ammonia detoxification and growth hormone stimulation. They are often used together — arginine pre-workout and ornithine before sleep.
