L-Glutamine (GI)
L-glutamine, (Gl) is an amino acid, which is important to normal brain activity. (Not to be confused with Glucosamine - an amino sugar – used for joint/cartilage support.) Gl, found in high concentrates in cerebrospinal fluid, improves mental clarity, concentration and mood. This amino acid can be used by cells as a source of energy and helps maintain blood sugar levels. Gl may help borderline diabetics avoid becoming insulin dependent. The clinical uses of supplemental Gl also include the treatment of alcoholism, colitis, ulcers and hypertension.
Gl is listed as a non-essential amino acid because your liver and kidneys naturally produce it. Gl supplementation became popular with athletes, bodybuilders and fitness enthusiasts about 15 years ago. Research has shown that intense physical activity rapidly depletes the body’s natural levels of Gl, which if not replaced, can deter the body from operating at optimal levels.
Gl is the most abundant amino acid found in the body, primarily located in the lining of the small intestines. It contributes a significant role in muscle metabolism during sickness, stress and exercise. Without the presence of Gl, the gastrointestinal tract cannot function. Gl is the primary treatment for ulcers and disorders of the small and large intestine such as irritable bowel syndrome, Crohn’s disease or colitis. It feeds the tissue of the small intestine enabling the villi to grow and improve absorption of nutrients across the cell membrane more efficiently.
Inside the liver, Gl is converted to a super powerful amino acid Glutathione, which is one of the main free radical fighters within the body. While other antioxidants (Vitamins E, C and Beta-Carotene) are important in the removal of free radicals, Glutathione does the lion share of the work, and a shortage of this vital compound puts a severe stress on the body’s immune system. Supplementing with Gl will also assist the body in resisting outside assaults from pathogenic microorganisms (bad bacteria).
Gl is the major component in producing neurotransmitters. Research has shown the supplemental Gl increases memory retention and cognitive ability. Additionally, it helps to maintain steady blood sugar levels. This is necessary for optimal brain function since the brain utilizes glucose (blood sugar) as a primary source of fuel in addition to oxygen.
The highest food based concentration of Gl is found in cottage cheese. However to obtain the necessary benefits of Gl from cottage cheese would require an active adult to consume 1-2 lbs daily. With the high content of sodium and saturated fat in processed cottage cheese, this would not be recommended on a daily basis.
Finally Gl is one of the required precursor amino acids for naturally producing human growth hormone.
