Glutamine is a non-essential amino acid with a characteristic composition, since it has two nitrogenous chains (an amino group and another amido). It is the most abundant amino acid in the blood and in striated muscle, participating in numerous biochemical processes:1. It is a primary energy source, donating hydrocarbon chains especially in muscle, lymphocytes, kidney and intestinal epithelial cells.2. It participates as a primordial substrate in hepatic neoglucogenesis as well as being part of the urea cycle.3. The generation of ammonium allows the synthesis of other amino acids, such as alanine and aspartate, through transamination reactions in muscle, intestine and liver.4. Glutamate deamination generates nicotin adenosine dehydrogenase (NADPH), involved in glutathione regeneration.5. Together with alanine it is the nitrogen transporter to the kidney. It is an essential amino acid for many important functions of different organs and systems of the body; in particular, the immune system and the intestine. However, during catabolic states, such as infections, surgery, trauma, physical exertion, and other states of metabolic acidosis, its requirements are greatly increased, its own homeostasis is disturbed, and glutamine stores may be depleted. During prolonged and/or high-intensity efforts, blood levels of glutamine increase considerably, to later suffer significant drops during the recovery period, taking several hours or days to recover the levels existing before exercise, leading to the so-called syndrome of overtraining. GLUTAMIN ZINC provides L-glutamine (Kyowa Quality®), as well as zinc, a micronutrient related to many functions, among others, it contributes to the normal functioning of the immune system and the protection of cells against oxidative damage. In addition, the addition of vitamin B6 to the formulation, it contributes to the normal metabolism of proteins and glycogen. Format: Container with 150 capsules of 800 mg each.
