View full detailsAbout L-Glutamine
L-glutamine is the most abundant amino acid in the body. It is a primary fuel for the cells that line the intestines and supports a healthy gut lining, immune function and muscle recovery after exercise.
This collection includes L-glutamine powders and capsules from NutriDyn, Klaire Labs, Pure Encapsulations, Thorne, Xymogen, Integrative Therapeutics and more.
How to Choose an L-Glutamine Supplement
- Powders: The best way to take gram-level amounts. L-glutamine powder is nearly tasteless and mixes into water or a smoothie.
- Capsules: Convenient for smaller daily amounts, usually 500 to 1,000 mg per capsule.
- Gut lining formulas: Glutamine combined with zinc carnosine, DGL or aloe for broader digestive and gut health support.
- Sports formulas: Glutamine paired with other amino acids for training and recovery.
L-glutamine is often taken with probiotics in a gut health routine, or after workouts with protein powder and creatine.
Frequently Asked Questions
What is L-glutamine used for?
L-glutamine supports a healthy gut lining, immune function and muscle recovery. It is the main fuel for intestinal cells, which is why it is a staple in gut health routines.
How much L-glutamine should I take?
Many people take 2 to 5 grams per day. Gut health routines sometimes use more. Follow the label or your practitioner's guidance.
Is L-glutamine powder or capsules better?
Powder is better for larger amounts. A single scoop of powder can equal several capsules. Capsules are convenient for smaller doses or travel.
When should I take L-glutamine?
Many people take it on an empty stomach or after exercise. Taking it consistently matters more than the exact time.
