Ornithine Alpha-Ketoglutarate
Supports muscle growth and recovery.
Also known as: OKG
Overview
Ornithine alpha-ketoglutarate (OKG) is a salt formed from two molecules of the amino acid ornithine and one molecule of alpha-ketoglutarate. It is a popular supplement among athletes and bodybuilders for its ability to promote muscle growth and enhance recovery. OKG is thought to work by increasing the production of growth hormone and insulin, both of which are important for muscle growth. It may also help reduce muscle breakdown and improve nitrogen balance. In addition to its muscle-building effects, OKG may also have other health benefits, such as boosting the immune system and improving wound healing.
