NOW Foods NOW Sports L-Glutamine is a 100% pure, free-form, non-essential, amino acid and is the highest grade available. NOW Sports Glutamine has recently been the focus of much scientific interest. A growing body of evidence suggests that during certain stressful times, the body may require more glutamine than it can produce. Under these circumstances glutamine may be considered a "conditionally essential" amino acid. Glutamine is involved in maintaining a positive nitrogen balance (an anabolic state) and also aids rapidly growing cells (immune system lymphocytes and intestinal cell enterocytes). In addition, glutamine is a regulator of acid-base balance and a nitrogen transporter.

What is Glutamine?
Glutamine is a non-essential amino acid; non-essential because it can be made in the body from another amino acid (AA) in the diet called Glutamic Acid. It is more appropriately considered a “conditionally essential amino acid” since some people may benefit by supplementation. Glutamine is the most abundant AA in human plasma and muscle.
What are the functional properties of Glutamine?
Glutamine is unique in that, along with glucose, it is one of the preferred energy sources utilized by rapidly growing cells. It is a major fuel source for the brain and - together with the stimulating neurotransmitter Glutamic acid and the inhibitory neurotransmitter GABA - they form the most abundant amino group in the human brain. Neurotransmitters are chemicals used by nerve cells to communicate with each other. Glutamine also supports intestinal cells’ health and normal function. It has been used clinically to improve nitrogen balance and minimize protein loss in those suffering with catabolic states (muscle breakdown) caused by surgical stress and gastrointestinal illness. In combination with N-Acetyl Cysteine, Glutamine promotes the production of a powerful cellular antioxidant called Glutathione that plays a critical role in the defense against free radical damage.
Will Glutamine help me with my health maintenance and exercise program?
Glutamine plays a major role in DNA synthesis and serves as a primary transporter of nitrogen into the muscle tissues. It serves to replenish nitrogen loss due to excessive muscle training and speeds up recovery. It is so vital to the building and maintenance of muscle tissue that 60% of the human intracellular amino acid pool is Glutamine. The very fact that muscle is the most important tissue for Glutamine synthesis and storage is evidence of Glutamine’s vital role in maintaining positive nitrogen balance and building these important support structures. Glutamine is utilized at a high rate by the cells of the immune system. It is also necessary for the production of hormone-like proteins secreted by immune cells that regulate the intensity and duration of an immune response to foreign organisms.
NOW Foods offers a high potency L-Glutamine, a multi-functional amino acid, at a dose of 1,500 mg. per tablet. NOW also sells other potencies of L-glutamine in capsules and tablets, and L-glutamine is part of almost every protein source, as this single amino acid accounts for about 60% of all free amino acids in the body.
L-glutamine is normally made from other amino acids in the diet, but as more may be needed by some people under certain circumstances it is called a “conditionally essential” amino acid. It is a key ingredient added to brain/mind formulas because it is effective at getting across the blood-brain barrier and it can serve as the brain's backup source of energy. L-Glutamine is the only amino acid tha:" ":y source of energy, the brain can utilize glutamic acid as a backup fuel.
L-glutamine has been effective in increasing the IQs of mentally deficient children. L-glutamine is also the precursor for the neurotransmitter GABA (gamma-amino butyric acid) for proper brain function and mental activity. It is found in both plant and animal proteins. L-Glutamine assists in maintaining the proper acid/alkaline balance in the body, and is the basis of the building blocks for the synthesis of RNA and DNA. No other nutrient is as important as glutamine for gastrointestinal health. Glutamine rapidly facilitates healing and restores the health of mucous membranes inside the colon (large intestine). Unlike other amino acids that have a single nitrogen atom, glutamine contains two nitrogen atoms that enable it to transfer nitrogen and remove ammonia from body tissues, regulating blood pH and protecting the kidneys and those with peptic ulcers. Glutamine supplementation reduces stomach inflammation caused by chemotherapy and can be useful in cases of diarrhea.
