L-arginine alpha-ketoglutarate may be superior form of L-arginine


L-arginine alpha-ketoglutarate (AAKG) is a timed release form of L-arginine which may be superior to the free form of L-arginine due to the fact that AAKG will raise and maintain nitric oxide (NO) levels for a longer period of time.

A study was conducted in 2006 and published in the Journal of Nutrition which indicated that AAKG positively influenced exercise performance in trained adult men over the non-timed release (free form L-arginine).
