Pure L-Glutamine amino acid (500mg) for muscle recovery and gut barrier integrity.
L-Glutamine is the most abundant free amino acid in muscle tissue and the preferred fuel for rapidly dividing intestinal epithelial cells. Each 500mg capsule delivers pharmaceutical-grade pure amino acid with no fillers, binders or flow agents — ideal for athletes, active individuals and anyone supporting post-exercise recovery or intestinal permeability.
Why This Formula
✔ 500mg pure L-Glutamine — no carrier compounds, no synthetic additives
✔ Supports muscle glycogen recovery — glutamine replenishes intramuscular glycogen stores post-exertion
✔ Gut lining maintenance — glutamine is the primary fuel for enterocytes and immune cells of the GI tract
✔ Flexible dosing — take 1-6 capsules daily depending on training intensity and recovery needs
✔ Vegan capsule shell — HPMC, free from gelatin and animal products
Who It's For
Athletes, regular exercisers, and anyone pursuing intensive training. Also valuable for those with compromised gut barrier integrity or seeking to support intestinal immune function and nutrient absorption capacity.

Reviews
I take l-glutamine immediately after exercise, as it's the most important amino acid involved in muscle recovery. There's nothing to criticise about this supplement. The manufacturer got everything right. Five stars.
The daily dose is from 1 to 6 capsules, so the 90 typical size capsules will last a few days or many. If you're a vegetarian or vegan, you may have a low level of L-glutamine, so this is good supplement
I know the capsules are L-Glutamine because, this amino acid wakes you up and if I take one before going to bed I cannot get to sleep.
No different, maybe they work for someone with mild symptoms
Prompt delivery. Good product at good price.
