Arginine alphaketoglutarate

From Wikipedia, the free encyclopedia

Arginine alpha-ketoglutarate or AAKG is an amino acid derivative commonly marketed as a body building supplement. An intermediate in the metabolism of nitric oxides, no reputable scientific evidence shows any benefits from taking AAKG as a dietary supplement.


"At present, there is no research published in peer-reviewed journals to support the assertion that an increase in nitric oxide levels promotes greater muscle protein synthesis or improves muscle strength. There is also no evidence that the arginine alpha-ketoglutarate in “nitric oxide” supplements have any effect on nitric oxide levels in muscles."[1]
