What Are the Benefits of Glutamine?

Glutamine provides a number of beneficial effects to the body. It is extremely important for the metabolism of protein, for increasing the volume of cells, and for preventing the breakdown of the muscles in your body.

Another function of glutamine is that it increases the secretion of human growth hormone (HGH) in your body. This helps to support the growth of new muscles as well as metabolize body fat. Glutamine is a great supplement if you are looking to lose body fat but keep your muscle.

Glutamine is also important for bodily functions and optimal performance. It improves the retention of nitrogen, decreases the time it takes to recover from an illness, and it decreases the chance of getting an infection.

Glutamine is great for people who are under physical stress, such as athletes, and those suffering from an illness such as heart disease or cancer.

Where Can You Find Sources of Glutamine?

Glutamine is found in many sources of both plant and animal protein, which means you can easily get the recommended amount in your diet from just eating certain foods. Glutamine can be found in beans, meat, fish, and dairy products.

More specifically, it is found in poultry, pork, and beef, as well as milk, cottage cheese, ricotta cheese, cabbage, raw parsley, and raw spinach. Small amounts of glutamine can also be found in fermented foods and vegetables, like yogurt and miso.

Glutamine is found in most protein powders, protein shakes, and protein drinks. It also can be purchased as a supplement and can be taken alone or added to protein shakes or powders.

Glutamine is considered to be a non-essential amino acid, so it is not necessary to worry about supplementing with it if you are a healthy person and are not a “gym rat,” athlete, or fitness buff.
