Often mentioned in the field of sport and gut health, glutamine is the most abundant amino acid in the body.
But what exactly is it used for, and why is it so highly promoted in food supplements? Let's find out!
A key amino acid
Glutamine is a semi-essential amino acid, as the human body can produce it, but not always in sufficient quantities.
During intense exercise, periods of stress, or digestive disorders, the body's demand exceeds natural production. It is in these situations that glutamine supplementation can be useful.
Support for the digestive system and intestinal barrier
Glutamine is the main energy source for intestinal mucosa cells. It contributes to the maintenance of the intestinal barrier, limits permeability, and plays a protective role against digestive disorders.
In certain cases, such as irritable bowel syndrome, a glutamine-rich diet or the addition of supplements can help strengthen intestinal health and reduce inflammation.
An ally for muscles and recovery
Glutamine also plays a major role in muscle tissue. During periods of intense effort, it contributes to protein synthesis, promotes muscle growth and recovery, while limiting mass loss.
It is therefore one of the most widely used food supplements by strength and endurance athletes.
Immune defenses and oxidative stress
Beyond muscles and the intestine, glutamine also contributes to the proper functioning of the immune system. It fuels immune cells and participates in defense against infections.
When reserves decrease, particularly after prolonged physical exertion, defenses can weaken, hence the importance of adequate intake.
A versatile supplement
In summary, glutamine is much more than just an amino acid: it contributes to the maintenance of gut health, the support of immune defenses, and muscle recovery.
It is for this versatility that glutamine is often included in supplementation programs, both for athletes and for people looking to improve their digestive comfort.
