L-Glutamine is an amino acid that naturally occurs in the body and is a building block of proteins.

In free form means it is not bound to other amino acids in a protein structure. It is immediately available for absorption, without first having to be broken down during digestion.

L-glutamine is often chosen by people with an active lifestyle, such as strength athletes and endurance athletes, as part of their diet and supplement routine.

L-glutamine is preferably taken between meals to prevent it from having to compete for absorption with other amino acids from food.

Glutamine is the most common non-essential amino acid in the human body, which means the body can normally produce it itself.
