L-Arginine and L-Ornithine are needed for production of growth hormones required for muscular energy, muscle tissue synthesis, muscle growth and repair. These amino acids play an important role in maintaining the liver and its functions to help flush toxins from the body and effectively produce bile to optimize fat metabolism. They help enhance collagen synthesis, and therefore may help speed up repair time and tissue injury. The addition of Vitamin B6 helps maximise absorption rate of the individual amino acids.
