Jarrow Formulas L-Glutamine 750 mg Supports Muscle Tissue and Immune Function 120 Caps

Product Profile Although a nonessential amino acid, L-glutamine has become the focus of extensive scientific interest because of its important physiological role. Since the 1980s, many researchers have come to regard glutamine as “conditionally essential. ” Conditionally essential nutrients are those which the body can produce in quantities sufficient to maintain health under normal circumstances, but for which the body’s needs outstrip synthesis under various conditions. In the case of glutamine, food restriction and other forms of physical and/or mental stress can cause the body to require more glutamine than will be available without supplementation. Under non-stressful conditions, adequate glutamine is synthesized primarily from glutamic acid, valine, and isoleucine. However, stress can decrease glutamine levels in the blood by as much as 30% and the levels in the muscles by as much as 50%. Distinguishing Features: Manufactured via microbiological fermentation USP/FCC grade 100% L-Glutamine Mechanisms Of Action Glutamine is important for muscle regeneration because it is an important precursor of nucleic acids, nucleotides, amino sugars, and proteins particularly by virtue of its ability to transport nitrogen between tissues. For this reason, glutamine is often used for enhancing exercise performance and supporting post-workout recovery.* Glutamine is used not only in the muscles, but also in the metabolism of the immune system, the intestinal tract, the kidneys, gallbladder, pancreas, and liver. Among amino acids, glutamine uniquely serves as a preferred energy source for rapidly dividing cells, such as those of the intestinal wall and the lymphatic system. As a result, glutamine is often recommended to support immune and gastrointestinal health.* Glutamine also acts as a regulator of the body’s acid-base balance – that is, it helps to maintain the proper pH of the system – through the buffering of ammonia. Glutamic acid reacts with ammonia when it is present in high concentrations producing glutamine. Glutamine also readily passes across the blood-brain barrier, where it serves as a precursor for both the stimulating neurotransmitter, glutamic acid, and the calming agent, gamma-aminobutyric acid (GABA). Glutamic acid does not cross the blood/-brain barrier. This could be why glutamine has been used to support and stabilize mood,
