Glutamine is a non-essential amino acid and is the most abundant free amino acid in muscle cells. It is a molecule that our body stores in the skeletal muscles and bloodstream, and converts into glucose (blood sugar) when it is needed.
L-Glutamine, the natural form of glutamine, is synthesised from 3 other amino acids: ornithine, arginine and proline. It is also a component of glutathione, a nutrient present in virtually every cell.
Our body’s own levels of glutamine can come under strain in circumstances of metabolic stress, including injuries, illness and even severe emotional distress.
