Glutamine is the most common amino acid in our muscles, making up over 61% of skeletal muscle! Glutamine is also the primary transporter of nitrogen into your muscle cells. Glutamine also plays a key role in protein synthesis.
Glutamine levels are depleted during intense exercise, which results in decreased strength, stamina and recovery. After your training, it can take up to 6 days for your Glutamine levels to return to normal. Supplementing L-Glutamine can help reduce muscle breakdown and can improve protein metabolism.
Glutamine is also one of the most important nutrients for your intestines and is the major fuel source for cells of the small intestine which promotes healing. It has the ability to ‘repair a leaky gut' by maintaining the structural integrity of the bowels, and it can even assist in curing ulcers! Studies have found that 1.6 grams of Glutamine a day had a 92% cure rate in 4 weeks. Plus it has also be proven to be an effective treatment for stomach ulcers, diarrhea, IBS and crohn's disease.
Glutamine is essential for maintaining intestinal function and aiding in the immune response as well. After Glutamine is synthesised in skeletal muscle it is released into the bloodstream and transported to the kidney, liver and small intestine and cells of the immune system where it plays another vital role.
