L-Glutamine for Leaky Gut: What You Need to Know to Take Control of Your Gut Health
Written by Clare Gibson
Published on May 23, 2023
The gut, often dubbed our 'second brain', plays a critical role in our overall well-being. It's entrusted with a variety of tasks, from absorbing nutrients to shaping our immune response. One supplement making significant strides in gut health is L-Glutamine. This prevalent amino acid comes loaded with numerous benefits, notably in bolstering our gut barriers and easing gut inflammation. Let's delve into how L-Glutamine is reshaping our understanding of gut health.
What is L-Glutamine?
L-glutamine is the most abundant amino acid in the body, playing a crucial role in numerous metabolic processes. It's the fuel that nourishes our gut cells, especially enterocytes, the frontline troops guarding our intestinal barrier. But L-glutamine's magic lies in its ability to fortify these defenses by tightening the "tight junctions" between enterocytes. These tight junctions act as gatekeepers, controlling what enters and exits the gut. When they're leaky, it's like having a porous fortress – harmful invaders (toxins, undigested food particles) can infiltrate, triggering inflammation and a cascade of health issues.
Can L-Glutamine Heal Leaky Gut?
Tight junctions serve as security guards for your gut. These protein structures seal the gaps between cells lining your gut, preventing harmful substances from leaking into the bloodstream. When these junctions are compromised—a condition often referred to as 'leaky gut'—it can lead to health complications such as food sensitivities, inflammatory bowel disease (IBD), and increased gut inflammation.
L-Glutamine steps in to fortify these tight junctions. Studies indicate that L-Glutamine supplementation bolsters the expression of tight junction proteins, thus improving gut barrier function and reducing the risk of 'leaky gut'. In fact, in patients with Crohn's disease, a type of IBD, L-Glutamine supplementation has been shown to improve intestinal barrier function
Additionally, L-glutamine supports the repair and regeneration of the intestinal lining. This process is crucial for healing the damage caused by leaky gut and restoring the structural integrity of the gastrointestinal tract.
Combating Gut Inflammation: The Anti-Inflammatory Effects of L-Glutamine
L-Glutamine plays another pivotal role by showcasing significant anti-inflammatory effects on the gut. When L-Glutamine is depleted, gut permeability increases, and inflammatory responses heighten. On the contrary, supplementation with L-Glutamine has been shown to inhibit inflammation, hinting at its potential role in managing conditions like IBD.
L-glutamine also plays a role in modulating immune response, helping to balance the inflammatory processes in the gut. By reducing inflammation, L-glutamine contributes to a healthier and more resilient gastrointestinal environment.

Additional Benefits of L-Glutamine
Beyond its remarkable impact on gut health, L-glutamine offers a myriad of benefits for overall well-being.
Muscle Repair and Recovery: As an essential amino acid, L-glutamine is a crucial component in muscle repair and recovery. Athletes and fitness enthusiasts often turn to L-glutamine supplementation to support their training regimens and enhance muscle health.
Immune System Support: L-glutamine is known to play a significant role in supporting immune function. It is a preferred energy source for immune cells and aids in the production of antibodies, contributing to a robust immune response.
Cognitive Function: The central nervous system relies on L-glutamine for neurotransmitter synthesis, impacting cognitive function and mood regulation. Adequate levels of L-glutamine are essential for maintaining mental clarity and emotional well-being.
Food Sources Rich in L-Glutamine
While supplementation is an option, incorporating L-glutamine-rich foods into your diet is a natural and effective way to boost your intake. Some examples of foods high in L-glutamine include:
1. Protein-Rich Foods:
- Lean meats (chicken, turkey, beef)
- Fish (especially tuna and salmon)
- Eggs
2. Plant-Based Sources:
- Legumes (beans, lentils)
- Quinoa
- Spinach
- Cabbage
3. Dairy Products:
- Yoghurt
- Milk
Supplementing For Extra Support
For individuals with leaky gut or compromised gut health, dietary L-glutamine might not be enough and you may need to seek targeted support from a gut health supplement like DAYLY. DAYLY combines L-glutamine with N-acetyl glucosamine (NAG), a compound known for its role in supporting gut mucosal health and healing leaky gut, as well as polyphenols and gut healing botanicals to provide comprehensive restoration to the gut.
