  gloutamini Glutamine is a non essential amino acid that can be synthesized in the body and takes part in protein synthesis. Most glutamine is stored in muscles and lungs, while rish fodd sources are beef, pork, poultry, yogurt, cabbage and raw spinach.

   In high stress conditions such as extreme athletic activity, injury or surgery, glutamine levels are lowered. Glutamine is protective for the brain and the digestive system, and can boost the immune system, while reducing insulin resistance due to stress.

   L-glutamine is the amino acid’s natural form that can be found in nutritional supplements in capsules, tables and powdered.

Properties and benefits

Wound healing and injuries

   During high strees conditions such as injuries, burns, surgeries, the body releases more cortisol and this lowers glutamine levels. Studies have shown that glutamine can enhance the immune system and wound healing, while can reduce lenght on hospital stay in critically ill patients.

Gastrointestinal system

   Glutamine protects the gastrointestinal mucosa from atrophy, and studies have shown that patients with crown’s disease and ulcerative colitis demonstrated low body levels of this amino acid. Glutamine is beneficial for individuals with nutrient absorption problems, and can reduce ammonia, alcohol and paracetamol toxic effects, by protecting the liver.

Brain function

   In the brain glutamine is converted to glutamic acid a substance that contributes to normal cognitive function and increases GABA levels. L-glutamine is also essential for proper glucose levels as a fuel for the nervous system.


   In high endurance athletes such as long distance runners glutamine body levels are often low. Glutamine intake before training can enhance the immune system and prevent hyper-training effects such as colds and fatigue. Also glutamine can help muscle building in combination with other amino acids, such as arginine and ornithine. Studies have shown that glutamine reduces lactic acid build up and muscle fatigue.


   Glutamine dosage depends on health state. A general rule is to take 50 mg of glutamine per kg daily, divided in doses.

Contraindications and side effects

   Patients with renal, liver disease, epilepsy or mania should not take glutamine. Also this amino acid can increase the effectiveness of certain chemotherapy drugs. Lactuolose and drugs for epilepsy should not be combined with glutamine. Children, pregnant and lactating women sould not take glutamine.
