What is Glutamine?

Glutamine is one of the twenty amino acids that make up proteins and is the most abundant in human blood plasma. It is classified as a non-essential—or conditionally essential—amino acid because the body synthesises it from glutamic acid, unlike essential amino acids, which must come from the diet. It is also obtained through diet, especially from meat, fish, eggs, dairy products, and legumes. In supplements, it usually appears as L-glutamine, which is the form present in the body.

Formats and how to compare

Powder allows for precise dose adjustment and has a lower cost per gram, but requires measurement or scales; capsules and tablets are practical for transport, with a fixed dose. Compare the grams of L-glutamine per serving and not the total weight of the package, and check the ingredient list, as some formulas include sweeteners, flavourings, or other active ingredients. Respect the daily dose indicated on the label. In case of pregnancy, breastfeeding, diagnosed illness, or medication, seek professional advice before starting.
