Glutamine
A non-essential amino acid important for muscle recovery, immune system support, and gut health. It helps reduce muscle damage, supports protein synthesis, and muscle mass, especially during intense exercise.
Glutamine is an amino acid found naturally in large amounts in the body. At Fitsport you will find L-glutamine powders and capsules. The products can look similar, so the most practical way to compare them is by the amount of glutamine per serving, the number of servings and the form.
What is L-glutamine?
Glutamine is an amino acid that the body can produce itself and that we also get from protein-rich food. Supplements most often use L-glutamine. It should not be confused with glutamate or GABA – these are different substances.
Glutamine powder or capsules?
Powder is convenient if you want to mix glutamine into water or another drink specified by the manufacturer. Capsules are easier to take when traveling, but one serving may consist of several capsules.
The Fitsport range includes, for example, "Amix Nutrition Glutamine 1000 g", "Amix Nutrition Glutamine 300 g" and "Amix Nutrition Glutamine 120 caps". Package sizes differ, so it is worth comparing the price not only per package but also per equal amount of glutamine.
How to choose a glutamine supplement
If you are looking for a product with a simple composition, check that the main ingredient is L-glutamine and that the formula contains no extra substances you do not need. Then compare the amount of glutamine per serving and how many such servings the package contains.
Flavored or complex products may contain sweeteners, flavorings or other ingredients. This is not bad in itself, but they should be compared as products with a different composition.
Glutamine benefits and the limits of the evidence
Glutamine is involved in many processes in the body, but sports supplement marketing often presents its effects more broadly than the evidence allows. That is why on this category page we do not promise that a glutamine supplement will by itself increase muscle mass, speed up recovery or cure gut problems.
In this category text we focus on the information that matters most for choosing a product.
Taking glutamine
Follow the manufacturer's directions for the specific product. Powder scoops and capsule servings can differ, so the serving of one product should not automatically be applied to another.
If you take medication, have health conditions, or are pregnant or breastfeeding, talk to a doctor or pharmacist about taking glutamine supplements.
Frequently asked questions
1. What is the difference between glutamine and GABA?
Glutamine is an amino acid, while GABA is a neurotransmitter. They are different substances, although their names are sometimes mentioned in the same context of amino acid metabolism.
2. When should I take glutamine?
Choose the timing and serving according to the product label. There is no single universal routine that suits all glutamine supplements.
3. Does glutamine help build muscle?
A glutamine supplement alone does not guarantee muscle growth. Muscle mass depends primarily on training, sufficient energy and protein intake, and recovery.
4. Does glutamine treat gut problems?
A food supplement is not intended to diagnose or treat gut diseases. If you have persistent digestive symptoms, see a healthcare professional.
5. Powder or capsules – which is better?
The form itself does not necessarily change the purpose of glutamine. Choose based on serving size, convenience and composition.
