L-Glutamine Effects: Why this amino acid is so important
What is L-glutamine?
L-glutamine is a non-essential amino acid that occurs in large quantities in the body. It plays a crucial role, especially for athletes, people with high stress levels, and those recovering from illness. Although the body can produce L-glutamine itself, the need for it increases significantly in certain situations – in which case, supplementation can be beneficial. MST® stands for quality trusted by professionals. Buy L-glutamine now and actively counteract muscle loss, fatigue, and weakened immunity.
Effects of L-glutamine in the body
1. Supporting the immune system
One of glutamine's most important effects lies in the area of immune defense. L-glutamine serves as an energy source for immune cells such as lymphocytes and macrophages. During intense training or illness, glutamine levels in the blood can drop – with negative consequences for the immune system.
2. Regeneration and muscle building
The effects of L-glutamine on muscle regeneration are particularly well-known in strength training. This amino acid reduces muscle breakdown (catabolism) and supports muscle rebuilding. Adequate glutamine intake can also reduce the familiar feeling of muscle soreness.
3. Gut health
Glutamine plays a central role in the health of the intestinal lining . It stabilizes the so-called tight junctions, which prevent harmful substances from the gut from entering the bloodstream. A healthy gut, in turn, is crucial for the immune system – thus completing the cycle.
4. Protection against muscle loss in stressful situations
Whether under physical or mental stress, the body draws on its glutamine reserves. Additional intake can help maintain muscle mass, stabilize the immune system, and keep energy levels balanced.

Which foods contain glutamine?
Those who want to consume glutamine through their diet should pay attention to protein-rich foods. Foods high in glutamine include:
-
Beef and poultry
-
eggs
-
Fish
-
Dairy products such as quark and yogurt
-
Legumes
-
Spinach and cabbage
However, even a high-protein diet often does not contain enough L-glutamine to meet the increased need, for example, during intensive training.
L-Glutamine intake: When and how much?
The intake of L-glutamine depends on the individual goal:
-
Athletes : 5–10 g per day, ideally divided into 2 portions – in the morning and after training
-
Regeneration/Immune system : 5 g daily, preferably in the morning on an empty stomach or in the evening before bed.
-
Gut health : Studies have successfully used dosages of up to 15 g per day.
L-Glutamine is tasteless, dissolves well in water or shakes, and is quickly absorbed by the body.
L-glutamine as a dietary supplement: Who benefits from it?
-
For competitive athletes and bodybuilders to support muscle growth and regeneration
-
People with weakened immune systems or in convalescence
-
People with irritable bowel syndrome or inflammatory bowel disease
-
Vegetarians/vegans , if few glutamine-rich foods are consumed
Conclusion: The effects of L-glutamine are scientifically proven.
Whether for strengthening the immune system , improving gut health , or as a recovery aid in sports – the effects of L-glutamine are diverse and well-documented. Those experiencing high levels of physical or mental stress benefit from targeted supplementation. The combination of scientifically proven efficacy and good tolerability makes L-glutamine one of the most popular amino acids in the field of supplementation.
