Published : Apr 01, 2020 5 mins read Updated On : Sep 14, 2023

Glutamine may be a mystery to many people who are yet to discover that it is one of the most copious amino acid present in our body. We bet you did not know that glutamine comprises of more than 70% of the amino acids found in your muscle cells and it is released into your blood stream during physical exertion and stress.

Normally, the human body is able to produce this essential amino acid to meet its metabolic processes, as it is present in most of the animal based and high protein food that you consume. L-glutamine is abundant in food sources such as fish, chicken, beef, pork, eggs, beets, cabbage, spinach, barley, and peanuts. However, athletes who indulge in physical activities require more of this essential amino acid.

The essentiality of glutamine is even more enhanced when you try to work out rigorously while you are unwell as there is a sudden depletion in this amino acid. This explains the reason athletes supplement glutamine as it improves the functions of the immune system and prevents excessive breakdown of your muscles.

Functions of Glutamine in Sports Nutrition

Glutamine is widely used in sports nutrition owing to its numerous beneficial features. Although there are several nutritional strategies that delay the onset of fatigue and improve athletic performance, nothing quite compares to the effect of glutamine. Fatigue impairs your ability to perform optimally as your energy levels are depleted.

The immune system of the body uses L-glutamine during intense physical workout and endurance exercises such as marathons, ultra distance events, and so forth. Studies reveal that impaired functions of the immune system and oxidative stress are often linked to deficiency of glutamine in athletes. For this reason, marathon runners and athletes must supplement glutamine as it helps to enhance sports performance by reducing fatigue.

How Does Glutamine Improve Your Performance?

Unlike body builders, marathon runners experience muscle breakdown weeks and months after the race, which tends to make them sick or worn out. It also explains the reason athletes are more prone to injuries in comparison to the others. However, this can be prevented through glutamine supplementation as it helps to reduce the level of muscle loss. This essential amino acid promotes recovery after different types of endurance activities and therefore improves your performance.

Glutamine has the unique capability to absorb salt and water into the muscle cells. Did you realize that a hydrated muscle is a healthy muscle?

Does Glutamine Really Work as an Anti Fatigue Amino Acid?

Well, that is a relevant question if you are an endurance athlete. Glutamine is vital for anyone who undergoes intense and frequent training. According to nutritional experts, the glutamine level in your blood reduces significantly after intense training and endurance activities. The body reaches a stage where it is deficient in glutamine and it requires more than it is able to produce through the diet. This stage is called glutamine depletion. During this stage, the muscle tissues are broken down to supply energy to the rest of the body, particularly the immune system.
