You have likely heard the buzz around the marvelous health benefits of L-Glutamine, but have you ever wondered what L-Glutamine is and why is it primarily used by bodybuilders and those with gastrointestinal disorders? Before we talk about the health endless benefits of L-Glutamine, it’s important to know what L-glutamine is.  

L-Glutamine: What exactly is it?

l-glutamineL-glutamine, often simply called glutamine, is the most abundant amino acid in the bloodstream. This amino acid affects the growth processes and function of cells in the stomach and intestines.1 Glutamine makes up 30–35 percent of the amino acid nitrogen in your blood and is considered a non-essential amino acid because it can be made by the human body and so is not essential to the human diet.2 Glutamine, found in the body, is typically stored in the muscles and the lung tissue and is distributed by the blood to the organs that need it.

Muscle-Building Properties of L-Glutamine Injections

There are over 650 different muscles in a typical human body that are essential to overall health and wellness. Healthy muscles provide the body with greater balance, agility, and strength. That is why it’s important to build and maintain as much muscle as possible, especially throughout the aging process. Fortunately, L-Glutamine’s endless benefits help support the body’s overall health, wellness, and proper functioning. Glutamine has been proposed to be playing a role in the control of muscle protein synthesis. Glutamine is thought to contribute to a positive nitrogen balance which promotes a cellular environment that is conducive to muscle building. 

L-Glutamine is also a cell volumizer, meaning that it promotes the uptake of water, which is also necessary for growth and consequently resistance to injury. Glutamine injection also supports the body’s ability to maintain an anabolic state where growth and efficient repair take place, especially when the body is stressed, injured, infected or energy-depleted. This makes it great for those who exercise often who want to optimize athletic performance and maximize muscle building.4

L- Glutamine: Its role in your digestive health

L-Glutamine goes beyond its role in supporting muscle growth and repair to protecting the gut. As the most abundant free amino acid in the human body, glutamine is a major substrate used by intestinal cells to promote intestinal barrier integrity and block bacterial infiltration during digestion.5  Disruption of the mucosal barrier can cause inflammation and tissue injury resulting in numerous gastrointestinal diseases such as increased intestinal permeability (leaky gut syndrome), inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), celiac disease, and infectious enterocolitis. Some cases of IBS may occur due to the deficiency of L-glutamine, and those who increase their L-glutamine intake may notice a reduction or disappearance of their symptoms.

Other Top Benefits of L-Glutamine Injections

  1. It improves IBS and diarrhea by balancing mucus production, which results in healthy bowel movements.glutamine injections
  2. Decreases muscle wasting
  3. Improves metabolism and cellular detoxification
  4. Curbs cravings for sugar and alcohol
  5. Improves diabetes and blood sugar level
  6. It helps with the intestinal absorption of important nutrients.
  7. It is an essential neurotransmitter in the brain that promotes brain health and also helps stall brain aging
  8. It is used to protect against the adverse effects of certain medical treatments, such as chemotherapy and radiotherapy
  9. It helps promote healing and reduce the risk of complications in critically ill people who have had traumatic injuries or burns or who have undergone surgery
  10. It strengthens the immune system.
  11. It helps naturally balance your pH levels.

Why do we need L-Glutamine Supplementation?

Glutamine is the most prevalent amino acid in the body, making up 20% of the body overall and 60% of skeletal muscle. Glutamine is classified as non-essential because the body can make it in sufficient amounts under optimal conditions, and thus does not need to get it from food. However, this does not mean it is not essential for health. Under certain circumstances, it becomes conditionally essential.

For example, during trauma and other catabolic stress, like injuries, falls, infections, wounds, and burns or even intense exercise like marathon training can cause a drop in the plasma concentration of glutamine. If the body cannot make enough on its own, the body rapidly drains its stores of glutamine, becoming much more vulnerable to slowed healing time, increased inflammation, infection, and immune suppression.6 Thus, L-glutamine supplements may be beneficial in maintaining plasma glutamine concentrations. 

L-Glutamine Deficiency

Some possible reasons that a person may likely experience L-glutamine deficiency include:

  • extreme physical stress from intense exercise
  • trauma or injury
  • malnutrition
  • major infections
  • undergoing radiotherapy or chemotherapy7
  • having immune disorders
  • chronic gastrointestinal disorders
  • old age
