L-Glutamine Powder — Gut, Muscle Recovery, and Immunity

The benchmark amino acid for gut health and recovery with Bionéo L-Glutamine Powder: 200g of pure powdered L-glutamine, the most abundant amino acid in blood plasma and muscle. Essential for the integrity of the intestinal mucosa, post-workout muscle recovery, and the functioning of immune cells.

Why is glutamine essential for the gut?

Glutamine is the primary energy fuel for enterocytes (cells of the intestinal lining) — it provides up to 70% of their energy through direct oxidation. Without sufficient glutamine intake, enterocytes divide less efficiently, tight junctions weaken, and intestinal permeability increases. Glutamine also stimulates the proliferation of immune cells (T and NK lymphocytes), which consume it heavily during infections or stress. During intense physical exertion, muscles release glutamine into the blood (muscle catabolism) — supplementation helps compensate for this loss and reduces markers of muscle damage (CK, lactate dehydrogenase).

Benefits of Bionéo L-Glutamine

• Support for intestinal mucosa integrity: Glutamine maintains tight junctions between enterocytes and reduces intestinal permeability (leaky gut), a factor involved in numerous chronic and inflammatory digestive disorders.
• Accelerated muscle recovery: After intense effort, glutamine supplementation compensates for muscle catabolism, reduces soreness, and accelerates muscle glycogen resynthesis.
• Immune support: Lymphocytes and macrophages use glutamine as an energy source — adequate intake maintains their effectiveness, particularly during periods of intense physical or psychological stress.
• Rapid-absorption powder format: The powder dissolves in a drink and is absorbed directly by the intestinal mucosa without prior digestion — ideal post-workout or on an empty stomach.

Composition

200g jar.

Who is this supplement for?

• People suffering from leaky gut, chronic digestive issues, or irritable bowel syndrome
• Athletes engaging in intense exercise looking to accelerate their recovery
• People under chronic stress or recovering from an infection
• People who have undergone heavy treatments (chemotherapy, prolonged antibiotics) that have altered the intestinal mucosa

Dosage

According to manufacturer guidelines. Generally 5g (1 teaspoon) to 10g per day, diluted in a cold drink. For athletes: take post-workout. For the gut: take on an empty stomach in the morning.

Precautions

• Epilepsy: Glutamine is a precursor to glutamate (an excitatory neurotransmitter) — not recommended in cases of epilepsy or seizure disorders without medical advice.
• Severe renal or hepatic insufficiency: Medical advice required.
• Pregnant or breastfeeding women: consult a doctor. Keep out of reach of children.
