Glutamine or Ornithine Alpha-Ketoglutarate
Glutamine is the most abundant free amino acid in human muscle and plasma, is utilized at high rates by rapidly dividing cells including your immune system, and provides energy and optimal conditions for RNA and DNA biosynthesis.( 1) Six amino acids are metabolized (made) in resting muscle. They are leucine, isoleucine, valine, asparagine, aspartate and glutamate. These amino acids provide the amino groups for synthesis of other amino acids such as glutamine and alanine.( 2)
