Benefits and synergies

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.

Composition

Acacia fiber - L-glutamine - Bamboo sap extract (Bambusa arundinacea) - Natural flavor - Marshmallow root extract (Althaea officinalis) - Medium-chain triglycerides - Natural flavor - Nicotinamide (vitamin B3) - Sweetener: steviol glycosides from stevia - Cholecalciferol (vitamin D3) from lichen extract - Riboflavin (vitamin B2).

Inavea™ is a trademark of Nexira.

  • 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.
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.

Acacia fiber

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.

TAKE MY ASSESSMENT
Is your gut sending you signals?

These signs may point to a weakened intestinal barrier. Stress, ultra-processed foods, antibiotics… our daily lives put it under strain.

  • Bloating, irregular bowel movements, digestion that's more sensitive than before
  • New food sensitivities
  • Persistent fatigue with no obvious cause
  • Deficiencies that don't improve
  • More reactive skin

The Glutamine & Fiber Powder cares for all 3 levels of the intestinal barrier. L-glutamine and vitamins B2 and B3 support the mucosa, marshmallow strengthens the protective mucus, and vitamin D3 supports immunity. Acacia fiber nourishes the microbiome. It’s the first step in your digestion routine.
