Ornithine Alpha-Ketoglutarate (OKG) is a salt made from the amino acid ornithine and alpha-ketoglutarate, a molecule central to how the body makes energy. Clinicians give it to patients after surgery, burns, or serious injury to help hold on to lean tissue and keep nitrogen levels steady. The dose arrives as a powder you mix with water or inside a ready-made nutritional drink.
The ornithine in OKG comes in a form that weakened patients can handle more easily than plain ornithine. This makes it a tool for clinical nutrition, not a routine supplement for healthy people. Researchers have studied it almost exclusively in hospital wards or in people who are malnourished. We have little solid data on OKG for athletes or for everyday recovery.
Do not use OKG outside of medical guidance. Nobody has checked its safety during pregnancy, breastfeeding, or with long-term use. Skip it entirely if you have kidney trouble or certain metabolic conditions unless your doctor tells you otherwise.
