  • Maximum-Strength L-Arginine Alpha-Ketoglutarate



  • Supports physical energy and faster muscle recovery



  • Supports healthy blood flow for optimal delivery of oxygen and nutrients to cells


Alpha-ketoglutarate, an amino acid compound used for energy metabolism, accelerates absorption of L-arginine. You'll enjoy steadier energy levels with the more efficient exchange of cell nutrients and wastes and speedier delivery of oxygen to the tissues. Supplementing with Arginine AKG also promotes faster muscle recovery after exercise and may support greater gains in anaerobic power when combined with a resistance training program.
