What Is Ornithine? Often touted as one of the more potent rejuvenators of all the amino acids, ornithine supplementation is a wonderful way to naturally enhance athletic performance and muscle recovery, as well as to improve muscle strength. It’s also quite effective to stimulate weight loss, accelerate wound healing, and enhance sleep quality. In a nutshell, ornithine is a “non-essential” amino acid that can be made inside the body from arginine (another amino acid). Despite this, supplementing with ornithine offers a wide range of health benefits.
