Arginine alpha-ketoglutarate (AAKG) is a salt of the amino acid arginine and alpha-ketoglutaric acid. It is marketed as a body building supplement. The components are intermediates in the metabolism of nitric oxides, but 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][unreliable source?]
A recent study examined the effects of AAKG supplementation on heart rate, blood pressure, blood flow, NOx/NO2 levels, and l-arginine levels. Minimal observed changes were attributed to resistance exercise used in the experimental design, not to AAKG supplementation, although arginine levels were found to have been elevated.[2]
