  • Glutamine is an amino acid.
  • Glutamine helps with the functions of the immune system and intestinal health.
  • Glutamine can be found in foods such as red meat and fish.

Glutamine is part of the protein building blocks in the body also known as the amino acids. It is one of the twenty amino acids in the body and is also the most abundant.

It is not as pertinent to the body because it is derived from glutamic acid, which is among the other amino acids as well.

While glutamine is among the other building blocks of protein, it also helps the body benefit from muscular structure, control blood sugar levels, and improve mentality.

Glutamine is known as a free amino acid because it floats around among the muscle tissue and helps to rebuild the muscular structure and the body’s immune system. It helps out with the immune system specifically when the body is stressed.

When you are stressed your body pulls the glutamine from the area of the muscles and brings it to the immune system for help. Under the same circumstances, it will then help regulate blood sugar levels as well. If you are under continuous stress, you may want to consider taking glutamine supplements.

Are There Any Known Side Effects of Glutamine?

Glutamine does not have any known serious side effects, yet it is not advised to take excessive amounts. Women who are pregnant and breastfeeding, as always, should take precautions when using any type of supplement. A patient who is pregnant or breastfeeding should only use this supplement if a doctor or health professional has recommended it.

How Do I Know If I’m Low on Glutamine?

The body needs glutamine as one of the amino acids for the building blocks of protein. However, it is not an extremely pertinent part of the body. The body can produce its own glutamine, so people are not likely to have a glutamine deficiency.

The body will be able to tell if it is low on glutamine. Some of the factors that contribute to low glutamine levels include frequent overexertion during exercise, recurring viruses or flu, low muscle mass or gastrointestinal issues.

Just because a person is experiencing one or more of these situations does not mean that they are low on glutamine. It is best to check with a doctor.

When Does Glutamine Kick In?

Glutamine plays a large role in the building blocks of protein when the body is low in muscle mass or is starting to waste muscle. Wasting muscle may come about from malnutrition or not getting the essential vitamins in your diet.

Once the body begins to waste muscle in order to compensate for the other vitamins and fat that the body is missing, glutamine has to step up to the plate. Glutamine is known for rebuilding muscle tissue and being an important amino acid for your bloodstream.

Glutamine may also be used to repair muscles after a workout, or even recover the body from soreness. Due to the fact that glutamine is naturally produced within the body, yet it can be taken additionally as a supplement, it has become popular among athletes.

Supplementation alone is not enough. Pair it with an exercise routine that can positively influence your lifestyle and fitness needs. Go PRO today for access to certified personal trainers, workout plans, and more.
