Glutamine: The Super Fuel for your Gut, Brain, Muscles, Digestion and More

Do you keep hearing about the amazing health benefits of glutamine? In the past, many bodybuilders and others in the fitness industry used glutamine in powder form (mixed into food or drinks) as a way to preserve muscle tissue. That’s because glutamine is an important amino acid that your body needs in large amounts in order to build protein.

In addition to helping build muscle, two other original uses of glutamine were to burn fat and lose weight. That certainly got the attention of many people.

As more research has been done, we have discovered that glutamine has even more tantalizing benefits. Glutamine is now used to elevate athletic performance. It can also promote digestive health, especially those with intestinal issues such as “leaky gut” (where the intestinal lining has become abnormally permeable, allowing undigested food particles, bacteria and toxic waste products to “leak” through the intestines into the blood stream). Other research shows that glutamine benefits brain health.

What is glutamine?

L-glutamine (or glutamine for short) is a key amino acid that is one of 20 naturally occurring amino acids found in protein-containing foods. In your blood stream, is the most abundant amino acid. Much evidence shows that glutamine is a conditionally essential amino acid. This means that your body can make some glutamine by itself, but during times of stress (such as in illness), the body’s requirements for glutamine can exceed the person’s ability to produce enough.

Because about 60% of your skeletal muscle is made up of glutamine, taking a glutamine supplement can assist your protein synthesis and as a bonus, can help balance your body’s internal pH levels.

This critical amino acid also promotes intestinal mucosa health, supports the preservation of muscle mass, and is necessary for the production of glutathione. Glutathione serves as an important liver antioxidant which helps prevent cellular damage from free radicals, peroxides, and heavy metals. Wow! What else can glutamine do for you? 

Immune Health Superstar 

As a precious building block of protein, glutamine performs many functions in the body. Your body needs adequate amounts of protein in order to support your immune system so it can transport white blood cells throughout your body (including “killer cells”, one type of white blood cell, which are able to identify and attack potentially harmful invaders). These killer cells use glutamine as fuel, but if the body is injured or stressed, blood glutamine levels may plummet. Low levels of glutamine can compromise your immune system and force your body to break down protein stores in order to release more amino acids.  

Superior Intestinal Health 

Your intestines also rely heavily on healthy levels of glutamine. Glutamine is a key energy source for your intestinal cells, which help keep the protective barrier between your intestines and the rest of your body healthy. The intestinal barrier prevents bacteria and toxins from leaking out of the intestines and into the rest of your body. Glutamine also supports healthy intestinal mucosa, which allows for the absorption of nutrients, such as vitamins and minerals, from your diet. 

Brain-Boosting Benefits 

Glutamine is one of the few amino acids which can effectively cross the blood-brain barrier. This stellar amino acid then plays a key role in biological functions, especially when the body is stressed such as after heavy exercise, during muscle recovery, or when your glycogen stores have become depleted. Glutamine also has a positive effect on mood and cognition due to its anti-inflammatory effects in your brain. This elite amino acid is known to reduce anxiety and also curb sugar and alcohol cravings – what an elegant benefit! 

The Bottom Line 

Glutamine is one outstanding amino acid that is recommended as part of your daily nutrition routine in order to maximize the health of your digestive system, intestines, muscles and brain health.

Although glutamine can be found in small amounts in foods, taking a glutamine supplement can guarantee higher levels of this amazing amino acid in your blood stream on a regular basis.

When selecting a glutamine supplement, go for the gold! Choose a top quality supplement made by a well-trusted company with a sterling reputation known for their strict quality manufacturing standards.
