L-Glutamine
L-Glutamine from Greatlife is a powerful supplement that supports muscle recovery and gut health. L-Glutamine is an essential amino acid that helps repair and strengthen the gut barrier and supports the immune system for optimal gut function. It is a pure supplement, free from additives, toxins, and artificial substances.
L-Glutamine is particularly known for its effects on restoring gut health after antibiotic treatment or other disturbances in the gut microbiota. By supporting the gut’s barrier function and immune system, L-Glutamine helps maintain a balanced microbiome and reduces the risk of intestinal inflammation.
Biologically, L-Glutamine is an amino acid that plays a central role in protein synthesis and tissue repair. In the gut, it helps strengthen the intestinal epithelium and protect against harmful microbes or inflammatory processes that can cause imbalance in the microbiota.
Studies have shown that L-Glutamine can help stabilise gut function after disturbances, improve recovery, and reduce inflammation. L-Glutamine is also known for its positive effect on muscle recovery, making it a great choice for those who train intensely or need quick recovery after physical exertion.
L-Glutamine from Greatlife is a reliable and effective supplement that provides support for both gut health and muscle recovery, with a pure and efficient formula that contains no unnecessary additives.

What is L-Glutamine?
L-Glutamine is an amino acid that the body produces naturally, but in certain situations, such as during stress, illness, exercise, or digestive issues, it may need to be supplemented through dietary sources. It is the most abundant amino acid in the blood and plays a central role in muscle recovery, gut health, immune function, and brain energy supply. Since the demand increases significantly during physical or mental stress, glutamine is considered a "conditionally essential" amino acid – meaning that the body may not always be able to produce enough on its own.
What does L-Glutamine do in the body?
L-Glutamine serves as fuel for rapidly dividing cells, particularly in the intestinal mucosa, the immune system, and muscles. In the intestine, glutamine is used as the primary energy source by epithelial cells, which helps maintain a strong intestinal barrier and reduce the risk of leaky gut. This makes glutamine particularly important in cases of digestive issues, candida overgrowth, IBS, and after antibiotic treatment. Glutamine also has anti-inflammatory and cell-repairing effects and may help balance the immune response in the gut.
How does L-Glutamine affect muscles and recovery?
During intense physical training or stress, the body's glutamine levels are quickly depleted, which can lead to reduced recovery, muscle fatigue, and a weakened immune system. Glutamine helps to restore glycogen levels, reduce muscle tissue breakdown, and accelerate recovery after exercise. Therefore, it is one of the most commonly used supplements among both athletes and individuals who train regularly.
How does L-Glutamine affect the brain and mood?
L-Glutamine also plays a role in brain function as it is a precursor to the neurotransmitters glutamate and GABA, which influence alertness, focus, relaxation, and sleep. A balanced glutamine metabolism can contribute to stable mood, mental clarity, and better stress management. Since glutamine also supports blood sugar balance, it may reduce cravings and fatigue caused by rapid blood sugar fluctuations.
Who benefits from taking L-Glutamine?
L-Glutamine is particularly useful for individuals looking to support gut health, recover after exercise, illness, or antibiotic treatment, or those experiencing fatigue, digestive issues, or high stress levels. It is also valuable in cases of leaky gut, candida overgrowth, or inflammatory bowel diseases, where the cells of the gut require extra glutamine to repair and strengthen the mucosal lining.
How should L-Glutamine be taken?
The recommended dose is two capsules daily, preferably 30 minutes before a meal. For best effect, it should be taken regularly over time. In case of temporarily increased need, for example after intense training or during ongoing stomach issues, the dose can be temporarily increased in consultation with a therapist. If swallowing capsules is difficult, they can be opened and the contents mixed in a cold drink or sprinkled on food.
Can L-Glutamine be combined with other supplements?
Yes, L-Glutamine works very well together with probiotics (e.g. Flora Plus+ or Bacillus coagulans LactoSpore®), NAC (for glutathione production and cell protection), and Zinc (for the intestinal mucosa). The combination of these supports both gut health and immune function deeply.
Are there any side effects?
L-Glutamine is very well tolerated and safe at the recommended dose. It can be used both short-term and long-term without known negative effects. At very high doses (several grams per day), some may experience mild stomach discomfort, which can easily be avoided by spreading the intake throughout the day.
When is the effect of L-Glutamine noticed?
The effect depends on the purpose of use. In cases of intestinal issues or leaky gut, improvement is often noticed within 1–3 weeks. For training and recovery, the effect can be felt within a few days through reduced fatigue and faster recovery. In cases of prolonged stress or digestive problems, improvement occurs gradually with continuous use.

A clean product with no GMOs.I’ve finally found your L-glutamine without GMOs and other unnecessary ingredients. It has worked wonders for my gut. I’ve had severe IBS since 1995.

I definitely notice a differenceI have a fairly recently diagnosed intestinal disease that causes an unsettled and unpredictable stomach. For the past six months I’ve been taking 2 capsules of L-Glutamine before breakfast because I heard it helps strengthen the intestinal lining. I definitely notice a difference. My stomach is calmer. I will absolutely keep taking it.
