What is L-glutamine?
Glutamine is one of the 20 amino acids the body uses to build proteins. It is one of the most abundant free amino acids in the human body, found in blood and muscle tissue.
Because the body can make its own glutamine, it is classed as non-essential, meaning it does not have to come from food. Most people also take in glutamine every day through protein foods.
Glutamine or L-glutamine: is there a difference?
Amino acids exist in two mirror-image forms, called L and D. The L form is the one found in proteins in food and in the human body. On supplement labels, "glutamine" and "L-glutamine" almost always mean the same thing, the L form.
Glutamine vs glutamate
The names are similar, but these are different molecules. Glutamine carries an extra nitrogen-containing group that glutamate does not have. Glutamate, also called glutamic acid, is a separate amino acid. The two are linked in the body through what scientists call the glutamate-glutamine cycle. Check the label to be sure which one a product contains.
Foods that contain glutamine
Glutamine is present in most protein-rich foods. Common dietary sources include:
- Beef, chicken, pork and fish
- Eggs, milk, yogurt and cheese
- Tofu and other soya foods
- Beans, lentils and other legumes
- Some vegetables, including cabbage and spinach
The glutamine content of a specific food varies, and most food labels do not list amino acids individually.

How to choose an L-glutamine supplement
1. Capsules or powder
Capsules give a fixed, measured amount with no mixing. Powders let you adjust the amount and are usually mixed into water or a shake. Both contain the same amino acid.
2. Amount per serving
Check the milligrams per capsule and how many capsules make one serving. Products range widely, from 500 mg to 1000 mg or more per capsule.
3. Single ingredient or blend
Some products contain L-glutamine only. Others combine it with other amino acids, vitamins or herbs. If you want glutamine alone, check the full ingredients list.
4. Capsule material
Vegetable capsules are suitable for vegetarians and vegans. Gelatin capsules are not.
