L-Glutamine: what is it and why is it beneficial?

Have you heard of L-fantastic Glutamine's health benefits? L-Glutamine, often known as glutamine, is an amino acid that is a building ingredient of protein and is required by your body in significant quantities. It was first utilized in powder form by people in the fitness sector, notably bodybuilders, who wanted to preserve muscular tissue.

The three main purposes for which L-Glutamine powder was initially used were to promote fat burning, increase muscle mass, and weight loss quickly.

While that is still the case, science has discovered numerous advantages of glutamine. Also, it improves the health of the brain and digestive system, increases athletic performance, and is beneficial in the treatment of leaky gut and intestinal problems. 

Among our most recommended supplements for treating leaky gut and/or building lean muscle, it ranks as the third most popular overall. Why is this so? Let's explore.

L-glutamine is a naturally occurring amino acid that is found in high concentrations in the human body. It is an important nutrient for the immune system and plays a critical role in the metabolism of cells throughout the body. In this blog, we'll explore what L-glutamine is, why it's beneficial, and how you can incorporate it into your diet.

What is L-glutamine?

L-glutamine is an amino acid that is classified as a non-essential amino acid, meaning that the body can produce it on its own. However, in certain circumstances, such as during periods of intense physical activity, illness, or stress, the body may not be able to produce enough L-glutamine to meet its needs.

L-glutamine is found in high concentrations in the blood and is used by cells throughout the body as a source of energy. It is also an important building block for proteins and plays a crucial role in the immune system.

Benefits of L-glutamine

  • Improves immune function : L-glutamine is essential for the proper functioning of the immune system. It is used by white blood cells to produce cytokines, which are proteins that help regulate the immune response. Research has shown that L-glutamine supplementation can improve immune function and reduce the risk of infections in people undergoing chemotherapy 

  • Supports gut health : L-glutamine is also important for maintaining the health of the digestive system. It is a key nutrient for the cells lining the intestinal tract and helps to maintain the integrity of the gut barrier. Research has shown that L-glutamine supplementation can improve gut function, reduce inflammation, and help to heal gut damage caused by conditions such as inflammatory bowel disease.

  • Helps with muscle recovery: L-glutamine is commonly used by athletes and bodybuilders to help with muscle recovery and reduce muscle soreness after exercise. It is also thought to help improve muscle strength and endurance.

  • Reduces anxiety and depression: L-glutamine may also have a positive impact on mental health. Research has shown that L-glutamine supplementation can reduce symptoms of anxiety and depression in people with major depressive disorder.

  • Enhances athletic performance: L-glutamine has been shown to improve endurance and reduce fatigue during exercise, which can help athletes to perform better.

  • Supports brain health: L-glutamine is a precursor to glutamate, which is an important neurotransmitter that helps to regulate brain function.

  • Helps with weight management: L-glutamine can help to reduce sugar cravings, and it may also help to boost metabolism and burn fat.

  • Supports overall health and wellness: L-glutamine is an important nutrient for the body, and it supports a range of processes that help to maintain optimal health and wellness.

  • Better Intestinal Health: Glutamine promotes the integrity of intestinal mucosa. Through this lining, you ensure that bacteria from digestion activity do not migrate throughout your body. It also enhances the immune function of intestinal cells by keeping them energized.

L-glutamine is also an anti-inflammatory. It calms tissues and lessens intestinal spasms, preventing several irritable bowel syndromes. A potent combination of both essential and non-essential amino acids called Prolab BCAA Plus and Glutamine can assist improve muscular growth, strength, and recovery.

How to incorporate L-glutamine into your diet

L-glutamine is found in a variety of foods, including meat, fish, eggs, and dairy products. However, the concentration of L-glutamine in these foods is relatively low, so it can be difficult to get enough L-glutamine through diet alone.

L-Glutamine is often included in BCAA (branched-chain amino acid) supplements, which are popular among athletes and fitness enthusiasts. BCAAs are a group of three essential amino acids: leucine, isoleucine, and valine. L-Glutamine is not a BCAA, but it is sometimes added to BCAA supplements because it is also important for muscle recovery and immune function.

L-Glutamine helps to reduce muscle soreness and supports the growth and repair of muscle tissue. It also helps to strengthen the immune system, which can be weakened during intense physical activity.

When L-Glutamine is combined with BCAAs, it can provide a more comprehensive approach to muscle recovery and support overall athletic performance. However, it's important to note that not all BCAA supplements contain L-glutamine, and not all L-Glutamine supplements contain BCAAs. Always check the ingredients label to ensure that you're getting the nutrients you need.

Fitspire BCAA is an all-in-one solution for strength, energy, and hydration with additional ingredients such as L-Glutamine which is known to help act as a source of fuel for the body. It is known to help sustain muscle strength for intensive workouts and helps to promote muscle growth, reduce muscle fatigue with improved recovery time.


L-Glutamine is a versatile amino acid that plays a critical role in the immune system, gut health, muscle recovery, and mental health. It is found in a variety of foods but can also be taken as a supplement to ensure that you're getting enough. Whether you're an athlete looking to improve your performance or someone looking to support their immune system and improve gut health, L-Glutamine is a nutrient worth considering.
