When it comes to custom-tailoring an amino acid formula to meet specific needs, nothing beats the versatility and functionality of free form aminos. Free form aminos have the ability, unlike intact, whole proteins, to rapidly enter systemic circulation, and thus exert potent pharmacological effects. Each 23 Aminos capsule contains 23 pharmaceutical-grade free form amino acids, including the key aminos, L-ornithine and L-arginine, L-glutamine and all three branched-chain aminos. 23 Aminos promotes positive nitrogen balance and increases protein synthesis. It is our ideal amino acid formulation.
