What is L-Gutamine Powder?
L-Glutamine is one of the twenty essential amino acids and is considered the most abundant free amino acid in the body. Amino acids are the building blocks of protein and help in the process of protein synthesis. These proteins also serve to transport substances in the blood and help fight off viruses and bacteria. This amino acid is also an integral part of the immune system, and because of this, it also plays a significant role in intestinal health. When discussing Glutamine, it is important to note that it comes in two forms, L-Glutamine, and D-Glutamine. L-Glutamine is produced naturally in the body and found in foods; it is most prevalent in blood and other bodily fluids.

L-Glutamine Benefits may include:

  • May promote increased muscle protein synthesis†
  • May assist a healthy immune system.†
  • May promote healthy digestion and intestinal tract.†

How Does L-Glutamine Powder Work?
L-Glutamine Powder is one of 20 essential amino acids and is considered necessary for the maintenance and promotion of cell function. Functions most notably promoted by L-Glutamine naturally found in the body include protein synthesis, a precursor for muscle growth, and as a fuel source for the body's immune cells. As a fuel source, studies have shown during stress, the body's requirements for Glutamine may exceed an individual's ability to produce. Supplementation of L-Glutamine may be a good idea for many people with an intense exercise regimen as it helps to heal all tissues in the body. L-Glutamine is also responsible for maintaining the integrity of the intestinal wall and promoting a healthy digestive tract. L-Glutamine ensures the integrity of the intestinal walls by promoting the healthy growth of enterocytes, a type of cell that lines the intestines. In conjunction with possibly supporting intestinal health, L-Glutamine may also work to promote a healthy immune system.
