When do you take L-glutamine?
Preferably between meals, as advised on the label. This way, it does not have to compete with amino acids from a high-protein meal. Take 1 capsule, 1 to 3 times a day, with a glass of water.

L-Glutamine 500mg by NOW Foods
This bottle contains 120 plant-based capsules, each containing 500mg of free-form L-glutamine. No powder to weigh out and dissolve, but a capsule you can take with a sip of water. The label recommends 1 capsule 1 to 3 times a day. Depending on how often you take one, a bottle will last six weeks to four months.
What glutamine is
Glutamine is the amino acid (a building block of protein) that is most abundant in your blood and muscles. About 60% of the free amino acids in your skeletal muscles is glutamine. Your body produces it itself, largely in those muscles, from glutamic acid and ammonia. In addition, you get it through protein-rich foods such as meat, fish, eggs, dairy, tofu, and legumes. An average diet provides about 3 to 6 grams per day. By the way, some of the glutamine in food is lost during heating. The L in L-glutamine stands for the left-handed form, the variant that occurs in nature and in your own proteins. Free form means that the amino acid is loose, so not fixed in a protein chain.
How your body uses glutamine
Many people wonder why glutamine in particular is mentioned so often. The answer: it is one of the busiest molecules in your metabolism. Glutamine has two nitrogen atoms, and that makes it an ideal carrier of nitrogen between your organs. Your muscles release it into your blood, and other tissues pick it up again. In addition, glutamine is a raw material for glutathione, for nucleotides (the building blocks of DNA), and for other amino acids. And your kidneys use it to keep the acidity of your blood in balance. In short: glutamine is less of a specialist and more of an all-rounder that stops by everywhere.
Capsules or powder, what suits you
The difference between glutamine in capsules and glutamine as powder lies mainly in the amount per time. In sports circles, glutamine is often used in doses of 5 grams or more, and then powder is more practical. If you want a small, fixed amount, without taste or hassle with measuring spoons, then capsules are easier. With 500mg per capsule, you dose exactly, from 500 to 1500mg per day. The label recommends taking the capsules preferably between meals. Good to know: glutamine is one of the less stable amino acids. In a damp environment or dissolved in water, it slowly breaks down. That is why there is a small amount of ascorbyl palmitate in this capsule, an antioxidant that protects the contents. Store the bottle in a cool, dry place after opening.
NOW Foods makes this glutamine in the United States according to GMP guidelines (Good Manufacturing Practice). The capsule is made of hypromellose, a plant-based cellulose, and the formula is not produced with wheat, gluten, soy, milk, egg, or nuts. Anyone looking for L-glutamine in a simple, measured form has a neat bottle with these 120 capsules at home.

Frequently Asked Questions
How much glutamine is in food?
An average diet provides about 3 to 6 grams of glutamine per day. Meat, fish, eggs, dairy, tofu, and legumes are the main sources. These capsules give you an extra 500 to 1500mg, separate from your meals.
Is L-glutamine the same as glutamate?
No. Glutamate (glutamic acid) is a different amino acid, and in the form of monosodium glutamate, you know it as a flavor enhancer. Glutamine has an extra nitrogen group. Your body can convert one into the other, but they are two different molecules.
Why capsules are more expensive per gram than powder?
Capsules are especially convenient if you want a small, fixed amount. You don't have to weigh anything, there is no taste, and you can take them anywhere. If you want large servings of several grams, powder is the better choice. So it all depends on how you want to use glutamine.
What does glutamine do in your body?
Glutamine is a nitrogen carrier between your organs and the most common free amino acid in your muscles. It also serves as a raw material for glutathione and for the building blocks of DNA. Your kidneys use glutamine to regulate the acidity of your blood.
What is the difference between L-glutamine and glutamine peptides?
L-glutamine is the free amino acid. Glutamine peptides are short protein fragments in which glutamine is bonded to other amino acids, often derived from wheat. They are more stable in liquid, but may contain gluten. This capsule contains only free L-glutamine, not produced with wheat or gluten.
