What it is
Glutamine is an amino acid, which is a basic building block that the body uses to make proteins. Specifically, it is found as L-Glutamine, the form that the human body can actually use and absorb.
Why it's used
It is primarily used to support gut health and aid in recovery after intense physical exercise. It helps maintain the lining of the intestines and supports the immune system during periods of high physical stress.
How it compares to BCAA
While both are amino acids used for recovery, they serve different primary roles in the body.

How it's made
Commercial glutamine is typically produced through a process called fermentation. Bacteria are grown in large tanks with a sugar source, and these bacteria naturally produce the amino acid as they grow. The glutamine is then filtered out, purified, and dried into a fine powder to be put into capsules or tubs.
What it typically costs
This supplement is generally mid-range in price. This is because the fermentation process is well established and efficient, but the purification steps required to ensure the powder is clean and safe for consumption add to the cost.
