I. Origin of glutamine
This amino acid, also identified as L-Glutamine, is a free amino acid, which means it does not combine with others to form a protein. It is widely present in our body, notably in our blood and muscles where it is the most abundant amino acid. Its role is essential in protein synthesis and the inhibition of their degradation process.
The production of glutamine in our body mainly comes from the foods we consume daily. Raw vegetables, legumes, dairy products, and plant and animal proteins are among these. The latter are rich in nitrogen, a key element in the synthesis of this amino acid.
Glutamine is not an essential amino acid, meaning it can be synthesized by the body. However, it can become temporarily essential in certain contexts. This is the case during stressful events such as intense physical training, serious illness, or traumatic stress (surgery, accident…). In these situations, its concentration can drop drastically in our body (up to 50%). A normal diet will then no longer be sufficient to compensate for this decrease. In such cases, it is recommended to supplement with this amino acid to prevent any undesirable deficiency.
It should be noted that this element is also produced in certain parts of our body, notably in the muscles and lungs. That is why it is so present in our muscles. Furthermore, it plays an important role in the functioning of our immune system and our intestinal health.
The organic variant, often referred to as Pure L-Glutamine, is obtained from natural sources and without chemical additives. It is distinguished by its purity and effectiveness. At D-LAB NUTRICOSMETICS, the focus is on the quality and naturalness of the ingredients, thus ensuring optimal bioavailability. Furthermore, our Pure L is derived from vegetable fermentation, which ensures a maximum concentration of essential nutrients. By adhering to the principles of organic farming, we promote sustainable and environmentally friendly production. Our manufacturing process also guarantees the absence of potentially harmful chemical residues, making our product perfectly safe for regular consumption.
II. Glutamine benefits
Athletes are not the only ones concerned with glutamine; its positive effects on the immune system and the intestinal lining make it an ally for everyone!
1. Repair muscles subjected to exertion
Glutamine allows for better physical recovery, especially during high-intensity training, such as weightlifting. Muscles are composed of 60% of this substance, and over time, intense physical efforts can lead to the degradation of muscle tissue and thus the amino acids present.
The recovery phase is important for athletes, and this amino acid plays a role in this process. Indeed, it improves the replenishment of muscle glycogen stores and thus the repair of tissues damaged during physical exertion.
Moreover, research shows that amino acids like glutamine can help speed up recovery after intense exercise by reducing muscle pain and improving muscle function.
2. Improve your sports performance
In bodybuilding
Dietary supplements containing this substance help to prevent and fight against overtraining syndrome. This syndrome significantly weakens the athlete's immune defenses by reducing their reserves, which can cause various infections. Moreover, it plays an essential role in protein synthesis, a crucial function for muscle growth and repair.
In sport
Apart from bodybuilding, glutamine is also beneficial for other types of sports. It helps maintain endurance and reduce fatigue, thus allowing athletes to extend their training sessions and improve their overall performance.
This element can also help reduce recovery time between training sessions, which can help increase the productivity of training sessions.
3. Maintain the integrity of the intestinal barrier
Glutamine plays a role in maintaining the intestinal barrier, which is necessary for good digestion.
Intestinal cells feed on this substance to develop. If they lack this energy source, the intestinal barrier becomes "leaky" and the intestine "permeable" because it does not filter the residues from the digestion process efficiently enough and allows toxic substances to enter the bloodstream.
Moreover, it can help maintain the balance of intestinal flora, which can contribute to good digestive health.
4. Before sleeping
Glutamine has calming effects on stress, promotes serenity, and facilitates rest.
Taking glutamine before sleeping can help improve sleep quality and reduce sleep disorders.
Indeed, it is a precursor of GABA, a neurotransmitter that helps reduce neuronal excitability and promote relaxation and sleep.
5. The benefits for the skin
It also contributes to skin health. It helps maintain hydration, promotes healing, and can reduce signs of aging by supporting collagen production.
Moreover, it acts as a fuel for skin cells, aiding in cell regeneration and skin tissue repair.
It can also help reduce inflammation and oxidative stress, which are two major factors in premature skin aging.
6. Immune system support
This amino acid plays a crucial role in the functioning of the immune system.
As the main fuel for immune cells, it helps strengthen the immune system and fight infections and diseases. Glutamine supplementation can therefore help maintain a strong and resilient immune system.
III. Where to find glutamine?
This amino acid valuable to our body, glutamine, is mainly found in animal and plant proteins.
Animal sources include chicken and fish, while plant sources include tofu, peas, lentils, and beans.
Other foods such as spinach, beets, cabbage, and cereals are also sources of this substance.
As a dietary supplement, it is often presented in the form of tablets or powder. These formats offer a convenient way to incorporate this amino acid into your daily routine, whether by adding it to your meals or drinks.
At D-LAB NUTRICOSMETICS, we offer the Pro-Collagen Digestion treatment, based on several elements including L-Glutamine, marine collagen, chicory, papain, and a combination of prebiotics and probiotics.
This supplement is an ideal solution to incorporate this amino acid into your diet, while benefiting from the other ingredients that promote your well-being.
1. Powdered
Its powder form is a popular supplementation option. It is easy to dose and can be added to drinks or smoothies for convenient consumption. This form is particularly preferred by those who want precise control over their intake of this amino acid.
2. In daily nutrition
Incorporating this substance into your daily diet is also a viable option. In addition to the sources mentioned earlier, other foods such as dairy products and certain vegetables can also increase your intake of this amino acid.
What is the food richest in this amino acid?
Among foods, chicken is one of the richest in glutamine. It is closely followed by fish, dairy products, and certain legumes such as peas and lentils. It is therefore recommended to include these foods in your diet to ensure an adequate intake of this amino acid.
IV. Glutamine Deficiencies
Glutamine is the most notable fuel for intestinal and immune cells.
A deficiency in this substance is often linked to sleep disorders, agitation, and difficulty concentrating. It has calming effects on stress, promotes serenity, and facilitates rest.
Furthermore, a deficiency of this amino acid can cause a decrease in immune function, poor post-exercise recovery, and an increased susceptibility to infections.
For these reasons, it is crucial to ensure an adequate intake, either through a balanced diet or through dietary supplements containing glutamine.
V. Our solutions for the microbiota and bloated belly
Bloating is caused by an imbalance of the microbiota (also called gut flora).
At D-LAB NUTRICOSMETICS, we offer a range of dietary supplements for the stomach and the microbiota.
We recommend in addition to Pro-Collagen Digestion:
- The Flat Belly Program.
A program focused on the gut, our second brain. Composed of 29 active ingredients, it will rebalance the digestive system to sustainably reduce waist circumference and regulate hormonal balance and stress to trigger weight loss while preventing fat storage.
Thus, vitamin B6 helps regulate hormonal and nervous activity, chromium and guarana support the metabolism of sugars and fats, and mucilage-rich fucus contributes to the balance of the digestive system for a lasting result on waist circumference.
- The Absolute Probiopure
Absolu, which is an association of 5 strains of lactic acid bacteria, the closest to the human intestinal microbiota, and are highly concentrated and encapsulated in a gastro-resistant capsule, to ensure maximum assimilation and harmonious development within the intestinal flora itself.
