L-Glutamine Boost — Pure Amino Acid for Gut Lining, Muscle Recovery & Immune Health

L-Glutamine is the most abundant amino acid in the human body and the primary fuel source for intestinal epithelial cells — the cells that line your gut. Despite its abundance, glutamine levels can become depleted during intense exercise, illness, stress or periods of digestive distress. L-Glutamine Boost delivers pure pharmaceutical-grade L-Glutamine in a convenient daily capsule, supporting gut integrity, muscle recovery and immune resilience simultaneously.

Why You'll Love It

  • Pure L-Glutamine — no fillers, binders or unnecessary additives; pharmaceutical-grade amino acid in its most bioavailable form
  • Gut lining support — L-Glutamine is the primary fuel for enterocytes (gut lining cells), supporting tight junction integrity and reducing intestinal permeability ("leaky gut")
  • Muscle protein synthesis — conditionally essential amino acid that supports muscle repair and recovery after intense training
  • Immune support — rapidly dividing immune cells also use glutamine as their primary fuel; supplementation supports immune cell production during times of physical or psychological stress
  • Recovery support — particularly valuable during illness recovery, after surgery, or during periods of intense athletic training
  • 90 vegan capsules — three-month supply of daily gut and muscle support

Key Ingredient

L-Glutamine (Pharmaceutical Grade) 500mg per capsule · Vegetable Cellulose Capsule

How to Use

Take 2–3 capsules daily with water. For gut health, take on an empty stomach. For muscle recovery, take post-workout. For immune support during illness or antibiotic recovery, take as directed by your healthcare provider. Not recommended during pregnancy without GP guidance.

Does L-Glutamine help with leaky gut?

Yes — L-Glutamine is the primary nutrient studied for supporting tight junction proteins that maintain gut barrier integrity. Multiple clinical studies and practitioners specialising in intestinal permeability recommend L-Glutamine as a foundational supplement for gut lining repair.

Can athletes benefit from L-Glutamine?

Yes. Intense exercise depletes plasma glutamine levels significantly. Supplementation supports faster muscle repair, reduced soreness and maintained immune function — particularly important for endurance athletes who are susceptible to immune suppression after heavy training.

Is L-Glutamine the same as MSG (monosodium glutamate)?

No. L-Glutamine and glutamate (the compound in MSG) are different. L-Glutamine is an amino acid and the body's most abundant nitrogen transporter. MSG is the sodium salt of glutamic acid, a flavour enhancer. They are structurally related but functionally distinct.

Is L-Glutamine Boost vegan?

Yes. The L-Glutamine is produced via fermentation using plant-derived substrates, and the capsule is vegetable cellulose. It is certified vegan and vegetarian.
