AOR Glycine - A versatile and important amino acid, Glycine is needed for the production of several important proteins and enzymes and is essential for detoxification. Due to its ability to stimulate the production of human growth hormone (hGH), glycine is primarily used to support muscle growth and repair and stimulate youthful effects on metabolism, bone growth and immunity. Glycine’s ability to decrease brain excitability has also made it useful for improving sleep quality as well as mood and emotional symptoms associated with brain disorders. Glycine also supports energy production, memory, blood sugar management and prostate health, as shown in several studies.
