L-Glutamine
Glutamine Powder is the most abundant amino acid found in human muscle and plasma. Over 60% of the free-floating amino acid pool in skeletal muscle cells is made up of L glutamine. It is also a primary nitrogen donor, meaning that it moves the nitrogen around in the body to where it is needed. Maintaining a positive nitrogen balance is absolutely necessary for muscle building. Glutamine Powder was once considered a non-essential amino acid because the body can make its own from the amino acids glutamic acid, isoleucine and valine.
