Description
L-Glutamine Powder provides pharmaceutical-grade free-form L-glutamine, the most abundant amino acid in the human body and a conditionally essential nutrient during times of physical stress, intense training, or gastrointestinal challenges.
While the body can synthesize glutamine under normal conditions, demand often exceeds production during periods of illness, heavy exercise, or digestive dysfunction.
Glutamine serves as the primary fuel source for rapidly dividing enterocytes (intestinal lining cells) and colonocytes, making it essential for maintaining intestinal barrier integrity.
Research demonstrates that glutamine supplementation helps preserve tight junction proteins between intestinal cells, reducing intestinal permeability commonly known as "leaky gut syndrome."
By supporting the structural integrity of the gut barrier, glutamine helps prevent unwanted substances from entering the bloodstream while maintaining proper nutrient absorption.
Beyond gut health, glutamine functions as a critical nitrogen transporter throughout the body, shuttling nitrogen to tissues that need it most—including immune cells, muscle tissue, and the liver.
Approximately 60% of skeletal muscle stores consist of glutamine, and levels can drop by 25% or more during prolonged intense exercise.
This depletion correlates with compromised immune function, making supplementation particularly valuable for athletes and active individuals.
The unflavored powder format allows for flexible dosing and easy integration into existing supplement protocols.
This product is non-GMO, gluten-free, dairy-free, soy-free, and vegetarian-friendly, manufactured in a GMP-registered facility to ensure pharmaceutical-grade purity.
How to use
How to use
Take 3 grams (approximately 3/4 teaspoon) per day mixed in water or your preferred beverage, or as directed by your healthcare practitioner.
Can be taken on an empty stomach for optimal absorption or post-workout to support muscle recovery.
For intensive gut healing protocols, higher doses (10-15 grams split into morning and evening doses) may be used under practitioner guidance.
Unflavored powder mixes easily into water, smoothies, or protein shakes.

Frequently Asked Questions
When is the best time to take L-glutamine?
For gut health, take on an empty stomach between meals. For muscle recovery, take post-workout. For immune support during heavy training, consider splitting doses throughout the day to maintain plasma levels.
How long does it take to see results for gut health?
Many people notice improvements in digestive comfort within 2-4 weeks of consistent use. For more significant intestinal barrier repair, 30-90 days of supplementation is typically recommended.
Can I take this with other amino acids or protein?
Yes. L-glutamine can be combined with other supplements and is often added to protein shakes. However, for maximum absorption, some practitioners recommend taking it separately from large protein meals.
Is this different from glutamic acid or glutamate?
Yes. While related, glutamine and glutamate are distinct amino acids. Glutamine is conditionally essential for gut and immune health, while glutamate functions primarily as a neurotransmitter. This product contains L-glutamine specifically.
