L-Glutamine is the most abundant amino acid in the body and is essential for the functioning of many tissues. It enhances exercise performance, muscle growth and recovery. The gastrointestinal (GI) tract is also one of the largest users of glutamine. SOLAL® Glutamine contains a micronised particle size for best absorption.

Glutamine enhances exercise performance, muscle growth and recovery. It aids in liver protection and detoxification, digestive complaints (irritable bowel syndrome, Crohn’s disease, colitis and leaky gut syndrome) and immune system functioning. It counteracts the damaging effects of Helicobacter pylori on gastric mucosa, repairs damage caused by chemo and radiation, elevates glutathione antioxidant levels, reduces sugar cravings by balancing sugar levels, aids in wound healing and tissue repair, stimulates growth hormone release, reduces alcohol cravings and liver damage, enhances mood, intelligence, learning and memory, alertness and reduces aggressiveness. It also improves stress-coping mechanisms, is beneficial in male impotence and is beneficial for autism and assisting with ADHD.

Pharmacological Action

Glutamine is the most abundant amino acid in the body and is essential in the functioning of many tissues in the body. Glutamine acts as an inter-organ nitrogen and carbon transporter. Tissues require glutamine for maintaining intestinal function, immune response, and amino acid homeostasis during times of severe stress. Glutamine is metabolised in the mitochondria and is important in providing metabolic fuel to lymphocytes, macrophages and fibroblasts. Glutamine is also used as a precursor in the manufacture of other amino acids, glucose, purines and pyrimidines, glutathione and glutamate. Following surgery or accidents one third of the nitrogen supplied for wound healing comes from glutamine. During physical exercise the body uses more glutamine than it produces. Its role as a carbon donor may explain its role as a “muscle food”. It seems to replenish glycogen stores and helps repair muscles after strenuous exercise leading to muscle growth. This can lead to muscle breakdown as the body tries to meet its glutamine requirements. The gastrointestinal (GI) tract is one of the largest users of glutamine. Depletion of glutamine can result in the atrophy, ulceration and necrosis of the intestinal epithelium. Glutamine’s GI benefits are also important in treating “leaky gut syndrome” and the associated allergies and possible arthritis associated with the syndrome. Since the GI cells undergo rapid division, glutamine is thought to prevent the GI damage caused by chemotherapy and radiation in cancer patients. Glutamine also helps protect the liver by its detoxifying action and by preventing fatty build up. Glutamine is an important source of fuel in the heart muscle as it is converted to glutamate, which then enters the Krebs cycle to create ATP, the bodies energy molecule. Glutamine plays an important role in balancing sugar in the blood stream. If sugar drops too low then glutamine can be catabolised to glucose in the liver. This is of great importance to people on calorie-restricted diets and as a means to reduce sugar cravings. Glutamine readily crosses the blood brain barrier where it is converted to glutamate or GABA. Some glutamate is also used for energy and some for the synthesis of glutathione and niacin. Glutamine is thus beneficial, by balancing various brain chemicals leading to improved memory, alertness and calmness as required. Glutamine also stimulates increased release of human growth hormone.

Dosage Directions


To boost growth hormone levels: Take 2 level scoops twice a day on an empty stomach.

To enhance physical performance: Take 2 level scoops 30 minutes before exercise, and another 2 scoops afterwards – to hasten recovery and remove lactic acid.

For all other benefits: Take 1-2 scoops twice daily, with or without food.

Children under 12 years of age:
Take half the adult dose.

Mix into water or fruit juice.

Product Warnings

People with kidney and liver failure should exercise caution in using supplemental glutamine. Do not exceed recommended dosages unless on the advice of a healthcare provider. Do not use this product if you are hypersensitive (allergic) to any of the ingredients. If you are on any medication or suffering from any medical condition, it is advisable to seek medical advice before starting any new medicine, supplement or remedy. This medicine has not been evaluated by the Medicines Control Council. This medicine is not intended to diagnose, treat, cure or prevent any disease.

Side Effects

The following less frequent side effects have been reported:
Mania in people suffering with bipolar disorder.


There are no known contraindications.


Anticonvulsants: Theoretically glutamine, which is metabolised to the excitatory neurotransmitter glutamate, might antagonise the anticonvulsant effects of medicines taken for epilepsy, use with caution.
Lactulose: Theoretically glutamine might antagonise the anti-ammonia effects of lactulose.
Chemotherapy: Glutamine may alter the pharmacokinetics of chemotherapeutic drugs, although clinical trials have not demonstrated reduced efficacy.
Diabetics: Diabetics should be careful when using glutamine as a larger percentage of glutamine is broken down to glucose due to an abnormal
diabetic glutamine metabolism.

Pregnancy and Breastfeeding

Safety during pregnancy and while lactating has not been established.
Pregnant and breastfeeding women should only use glutamine under the supervision of a medical practitioner.
