Kyowa Announces GRAS Self-Affirmation for L-Ornithine

October 31, 2013 New York, NY

Kyowa Hakko U.S.A., Inc. (Kyowa Hakko USA), the wholly-owned subsidiary of Kyowa Hakko Bio Co., Ltd., (Kyowa), has announced it has completed GRAS (Generally Recognized As Safe) self-affirmation for the valuable amino acid L-Ornithine.

L-Ornithine is an amino acid that is used to build muscle by stimulating protein synthesis through the enhancement of growth hormone secretion and to assist weight loss by increasing the basal metabolism. It is also known that L-ornithine has the ability to enhance immunity, liver function and anti-fatigue.

“We are excited about having GRAS for L-ornithine, as this will expand the use of this important amino acid into traditional food and beverages,” said Dr. Toshikazu Kamiya, CEO & President of Kyowa Hakko USA.

Research supported by Kyowa Hakko Bio suggests that L-ornithine has an anti-fatigue effect by increasing the efficiency of energy utilization and promoting the excretion of ammonia.
