Ornithine HCL

Ornithine HCL from The Protein Works™ is a powerful amino acid compound which has been shown to possess rejuvenating properties. This is particularly important during periods of intense training since it helps the entire body recover. This is why many athletes will add this to their post workout shake to help cope with the immune crash that occurs following a hard training session. Ornithine HCL has also been shown to improve the body’s response to bacteria and viruses in addition to detoxifying the body of ammonia.

Ornithine HCL Benefits

Ornithine HCL is also traditionally taken before bed to promote muscle repair and recovery processes that naturally peak 90 minutes after falling asleep. This ultimately enhances sleep quality, improves the entire recovery process and helps muscles, the immune system and neurotransmitters. This overall promotion of repair and recovery in the body in general has been shown to help increase muscle mass and reduce body fat. This is another reason why Ornithine HCL features in so many athlete’s supplement routine.
