Alpha Ketoglutarate (AKG)
AKG (alpha-ketoglutarate) is the nitrogen-free portion of the amino acids known as glutamine and glutamic acid. It is formed in the Krebs cycle, the energy-producing process that occurs in most body cells. AKG is used by cells during growth and in healing from injuries and other wounds,1 and is especially important in the healing of muscle tissue.2 A controlled study found that intravenous AKG prevented a decline in protein synthesis in the muscles of patients recovering from surgery.3, 4 For these reasons, it has been speculated that oral AKG supplements might help improve strength or muscle-mass gains by weightlifters, but no research has been done to test this theory.
- Reliable and relatively consistent scientific data showing a substantial health benefit.
- Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
- This interaction is supported only by weak, fragmentary, and/or contradictory scientific evidence.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
