Benefits and synergies
L-GLUTAMINE
MARSHMALLOW
ACACIA FIBER
VITAMINS B & D
For comprehensive support for the intestinal barrier, we’ve combined L-glutamine with marshmallow, vitamins B2, B3 and D3, and acacia fiber.
Gentler digestion: Marshmallow strengthens the mucus layer, the first layer that protects the intestine. It contributes to the normal functioning of the intestinal tract and supports digestion, helping you feel more comfortable day to day.
A more resilient gut: L-glutamine nourishes the cells of the intestinal lining and supports their renewal. Vitamins B2 and B3 contribute to the maintenance of normal mucous membranes. The result: a stronger barrier that better filters what enters the body.
Better nutrient absorption: A healthy intestinal barrier absorbs nutrients more effectively, so your body can get the most out of what you eat. Acacia fiber nourishes beneficial bacteria and supports more regular bowel movements.
Better protection for your body: Vitamin D3 contributes to the normal functioning of the immune system, much of which is found in the intestine.
For whom?
This powder is for those who feel that something isn’t working quite like it used to (more sensitive digestion, fluctuating energy, a more reactive system…) and are interested in the role of the intestinal barrier, often referred to as leaky gut, to focus on addressing the root cause rather than finding a temporary solution.
It is particularly suitable for:
People prone to regular digestive discomfort (sensitive stomach, bloating, difficulty digesting, food sensitivities or irregular bowel movements) whose digestive system has become more reactive, sometimes unpredictable, and less tolerant than before.
People exposed to a lifestyle that places a little too much strain on the gut (chronic stress, a modern ultra-processed diet, antibiotic treatments, environmental pollutants) who are looking to support their gut in the face of factors they can’t always control.
People prone to recurring deficiencies that don’t resolve.
People who feel their body is more vulnerable than usual (recurring fatigue, repeated minor infections, more difficulty recovering).
People who have already tried probiotics without satisfactory results who are looking for a more holistic approach focused on the intestinal barrier before considering another course of probiotics.
This course can also be used as part of a maintenance routine to support the intestinal barrier over the long term, even in the absence of significant issues.
Usage tips
Dilute 1 stick per day in a glass of water (ages 12+), ideally on an empty stomach or between meals.
Use for a minimum 1-month course to help support the intestinal barrier and digestive comfort. For longer-term support, the course can be extended to 2 to 3 months. Several courses per year are possible, depending on your needs.
And it bears repeating: food supplements should be used as part of a healthy lifestyle. For better storage, keep this product at room temperature in a clean, dry place.
Marshmallow contributes to the normal function of the intestinal tract and supports digestion.
Vitamin D3 plays a role in the process of cell division and also contributes to the normal function of the immune system.
Vitamin B2 (riboflavin) and vitamin B3 (niacin) contribute to the maintenance of normal mucous membranes.

Glutamine & fiber powder
FLAGSHIP
Acacia fiber
Derived from acacia gum, this prebiotic fiber ferments in the lower intestine, where it nourishes beneficial gut bacteria. This fermentation produces butyrate, a fatty acid that helps maintain the integrity of the intestinal barrier.
In one study, acacia fiber increased intestinal barrier impermeability by 75%, indicating tighter junctions between cells and a more effective filter.
*In vitro study conducted on human intestinal cells grown in a laboratory and exposed to acacia fiber. The strength of the cell barrier was measured using the TEER test: the higher it is, the tighter the junctions between cells.

Frequently asked questions
What is L-glutamine?
L-glutamine is an amino acid, like glycine, leucine, or tryptophan, that is part of proteins. It is called “nonessential” because our bodies can produce it naturally. However, in certain situations (physical stress, intense exercise, recovery from illness…), our needs may be greater.
L-glutamine is especially abundant in the intestine. Cells in the intestinal lining, called enterocytes, use it as one of their main energy sources. It therefore helps these cells renew themselves and contributes to maintaining the integrity of the intestinal lining. This lining plays an essential role by enabling the absorption of nutrients while limiting the passage of unwanted substances.
In which situations is L-glutamine particularly beneficial?
L-glutamine can be part of a digestive support routine for people who regularly experience intestinal discomfort such as bloating, difficult digestion, or irregular bowel movements, along with the feeling that their digestive system is more reactive than before.
It may also be of interest to people whose digestion is directly affected by stress, causing a sensitive stomach or digestive upset during periods of mental strain or fatigue.
It may also be considered in cases of persistent fatigue with no obvious cause, the feeling of being “less efficient in everyday life,” or symptoms that may suggest an inflammatory condition. It is also sometimes incorporated into a more comprehensive approach, particularly when options such as probiotics have not produced the expected results, or in lifestyle contexts that place particular demands on the gut (modern diet, antibiotics, environment).
Finally, it can simply be used as part of an annual maintenance course to support the intestinal barrier, even in the absence of significant symptoms.
What is meant by “leaky gut”?
The term “leaky gut” literally means “gut that leaks.” In French, it is called increased intestinal permeability. It refers to a disruption of the intestinal barrier, which becomes more permeable. In practical terms, the intestinal barrier loses some of its filtering function: certain unwanted substances (food fragments, bacteria, toxins...) can then pass more easily through the intestinal lining and come into contact with the body, even though they should normally remain in the intestine or be eliminated.
This phenomenon is now widely studied by researchers. Increased intestinal permeability is observed in certain digestive diseases and is also the subject of extensive research to better understand its links with other conditions, such as autoimmune diseases, allergies, food intolerances, and certain inflammatory diseases.
What signs might point to “leaky gut”?
Digestive discomfort (difficulty digesting, bloating, diarrhea, irregular bowel movements), a feeling that digestion isn’t working optimally or that the digestive system is more sensitive than before, persistent fatigue with deficiencies that seem difficult to correct, or increased reactivity, with allergies or intolerances. Recurring skin issues (eczema, psoriasis, acne, etc.) are also common, along with increased sensitivity to stress, anxiety, or sleep disturbances that point to an overall imbalance in the gut-brain axis.
In short, a supplement such as Glutamine & Fiber Powder may be suitable for many people and can be taken before other supplements to optimize their absorption and support digestive comfort.
How do you know whether the priority is to repair the mucosa (glutamine) or rebalance the microbiome (probiotics)?
The logic is simple: L-glutamine acts on the intestinal lining, while probiotics act on the microbiome.
In practice, when the digestive system is more sensitive (regular discomfort, difficulty digesting, irregular bowel movements, increased sensitivity), the usual first step is to support the intestinal lining with L-glutamine to strengthen the quality and integrity of the gut barrier.
Once the digestive environment has stabilized, probiotics can be introduced to rebalance and enrich the gut microbiome.
The two approaches complement each other.
Can Glutamine & Fiber Powder and the Probiotic & Fiber Course be taken at the same time?
Yes, they can be taken at the same time. L-glutamine (Glutamine & Fiber Powder) is used to support the quality and integrity of the intestinal mucosa and prepare the digestive system. Probiotics (Probiotic & Fiber Course), meanwhile, help restore the balance of the gut microbiome by replenishing and diversifying beneficial bacteria.
What other pillars should be worked on in parallel?
Diet and stress are two of the main factors that influence the balance of the intestinal mucosa.
Choose a diet that is as natural and balanced as possible, limiting ultra-processed products and favoring foods rich in fiber and nutrients that are generally anti-inflammatory.
Work on better managing stress and the nervous system. Stress can disrupt digestion, the balance of the microbiome, and the proper functioning of the intestinal mucosa.
What time of day should I take my course of treatment?
Glutamine & Fiber Powder can be taken at any time of day, according to your routine. It is often consumed in the morning on an empty stomach or between meals for better absorption. The most important thing is to take it regularly, every day, to get the most out of your course.
How long is it recommended to take Glutamine & Fiber Powder?
We recommend a course of at least 1 month to support the intestinal barrier and digestive comfort. Depending on each person's digestive issues, the course can be extended to 2 or 3 months. It can also be taken as a maintenance course 1 to 2 times a year, depending on your needs.
Does Glutamine & Fiber Powder contain any allergens?
No, our Glutamine & Fiber Powder contains no allergens. In particular, it is gluten-free and lactose-free. The formula is also vegan. All ingredients are plant-based or synthetic. L-glutamine is obtained by fermenting plant-based raw materials (corn), and vitamin D3 comes from lichen, a natural organism formed by the association of an alga and a fungus.
