Nitro4™ is a complete "cell volumizing" supplement containing 4 powerful ingredients including Arginine-Alpha-Ketoglutarate (AAKG) known as a precursor of the gas Nitric Oxide (NO2) and catalyst for NO2 synthesis. Arginine-Ketoisocaproate (AKIC) to further the effects of NO2 production, as well as Ornithine-Alpha-Ketoglutarate (OKG) which preserves muscle protein synthesis and spares nitrogen. Glutamine-Alpha-Ketoglutarate (GKG) which helps support cell volumizing by preserving the amino acids glutamine and taurine, and increases amino acid transport.
