THP L-Glutamine 250g, Pure Pharmaceutical-Grade Glutamine for Recovery and Gut Support
The Health Project L-Glutamine is a pure unflavoured glutamine powder for daily recovery and gut support use. Each 5g serving delivers 5g L-Glutamine. The 250g tub provides 50 servings.
L-Glutamine is conditionally essential: under normal conditions the body synthesises sufficient amounts, but during sustained high-intensity exercise or caloric restriction the demand exceeds synthesis capacity. Intramuscular glutamine is depleted by up to 50% during exhaustive training, impairing both protein synthesis rates and the gut barrier function that prevents pathogen translocation. Intestinal epithelial cells consume glutamine at a high rate to maintain the tight junctions that constitute the gut barrier; supplemental glutamine supports this directly. Lymphocytes and other immune cells use glutamine as their primary nitrogen fuel, making adequate supply important for immune competence in the post-exercise window.
What separates THP L-Glutamine from an EAA or BCAA powder with trace glutamine is dose specificity. Research on gut barrier integrity and immune support uses dedicated 5g glutamine doses. Amino acid blends provide glutamine incidentally at sub-clinical doses that do not replicate this effect. A standalone 5g powder provides dose control that blends cannot.
THP L-Glutamine suits high-volume resistance trainers, endurance athletes managing gut health, bodybuilders in calorie-restricted phases where immune suppression is a concern, and anyone who has previously found high-protein diets trigger digestive discomfort. It is not a protein supplement and does not contribute meaningfully to daily protein targets. Contains no major allergens.
Key Benefits
Muscle Recovery
Replenishes depleted glutamine stores to accelerate post-training muscle repair
Immune Support
Maintains immune function during periods of intense training when the body is most vulnerable
Gut Health
Fuels intestinal cells and supports gut barrier integrity for improved digestive wellbeing
Anti-Catabolic
Helps prevent muscle protein breakdown during intense or prolonged exercise sessions
What is glutamine used for and do I need it if I take whey protein?
Glutamine supports muscle recovery, immune function and gut lining health. Whey protein contains some glutamine naturally, and THP Ultimate Whey also includes added glutamine peptides. However, during intense training blocks or periods of physical stress, your body may use glutamine faster than it can produce or obtain it from food. A standalone 5g supplement provides a dedicated top-up in those situations.
When is the best time to take L-glutamine?
Most users take L-Glutamine post-workout mixed into a protein shake, or before bed for rest-day recovery support. The 5g dose can be split across the day if preferred - timing is flexible since glutamine routine support comes from consistent daily use rather than a specific window.
Is THP L-Glutamine suitable for vegans?
The product is pure L-glutamine powder with no animal-derived ingredients listed. It is manufactured with no known allergens. While it is not explicitly certified vegan, the single-ingredient formula does not contain any animal products. The manufacturing facility handles milk, eggs, soy, wheat, nuts and peanuts, so people with severe allergies should be aware of potential cross-contamination.
