Amino Acids



Ornithine is a non-essential amino acid that the body can synthesize from arginine. Its main function is to participate in the excretion of uric acid by the liver, but it can also help improve sleep, increase the production of anabolic hormones, and stimulate the immune system. Ornithine was discovered in the 1880s by the German chemist Hugo Weidel. He isolated it from bird urine and called it “ornithine” because of its origin. Ornithine is important for protein metabolism and is found in many foods, such as meat, fish, vegetables, and supplements.

Ornithine is an amino acid that is indispensable for cellular metabolism and function. In addition to participating in protein synthesis, ornithine also plays a role in the urea cycle, which is the process by which the body eliminates ammonia. Ornithine is also important for immune function, bone health, and the maintenance of muscle mass. In addition, ornithine is an amino acid that is a precursor to arginine, another important amino acid for the body. Ornithine is an amino acid that can help improve sleep.
