Why do bodybuilders care about the benefits of the best glutamine? Glutamine is an amino acid crucial in the synthesis of proteins by body cells. Usually, the body can produce the amount of glutamine it needs, however in cases of heavy workouts and rigorous training, the demand for the amino acid heightens and can be supplemented for peak health.

Many athletes and fitness enthusiasts already enjoy L-glutamine supplements to replenish dwindling stores, build lean muscles, and promote protein synthesis. 

Studies suggest glutamine supplements can also boost your immune system, reduce fatigue and even improve survival leading to the critically ill. This article covers all of the benefits of glutamine and frequently asked questions.

We provide Glutamine in our line of supplements because it helps replenish depleted muscle stores, builds new lean muscle, and protects hard-earned gains by supporting protein synthesis. To view Prolab Glutamine,  Click HERE.

What is Glutamine?

Glutamine is an amino acid that supports protein synthesis in the body. Proteins play an important role in supporting and protecting vital organs. They also help transport substances in the blood to repair muscle and combat harmful viruses.

As mentioned, the body naturally produces glutamine. Still, in some conditions the amino acid demand is high, and it must be obtained from food or supplements.

Naturally, there are two forms of glutamine: L-glutamine and D-glutamine. L-glutamine can also be found in beef, fish, chicken, dairy products, beans, spinach, cabbage, beets, carrots, parsley, wheat, papaya, kale, and Misco. 

Depending on your diet, you can get 3-6g of it per day. Glutamine supplements contain L-glutamine too, an essential form used for synthesizing protein.

Why might you experience L-glutamine deficiency?

Some reasons for L-glutamine deficiency in your muscle cells could be as follows:

  • Trauma
  • Major infections
  • Intense physical workouts
  • Chemotherapy or radiotherapy
  • Immune disorders such as AIDS
  • Lack of sufficient glutamine in your diet
  • Stubborn gastrointestinal disorders such as inflammatory bowel disease
  • Extreme stress or shock causing the body to release cortisol leading to the breakdown of glutamine stores in tissues

5 Glutamine Supplement Benefits

Prolab glutamine is a micronized powder that mixes easily in hot or cold drinks or other soft food substances. Using a micronized glutamine supplement provides a versatile free-form L-glutamine for building and protecting lean muscles. Below are five benefits of supplementing with glutamine.

Supplements help replenish depleted glutamine levels in your muscles.

In conditions of injury, illness, or stress, L-glutamine level decreases, and the body breaks down the amino acid stores in muscles to make up for the deficit. Additionally, insufficient levels of amino acids lead to poor immune system functioning.

High glutamine protein diets or glutamine supplements are often prescribed in conditions of illness or injuries like burns, sickle cell anemia, bone marrow transplant, HIV/AIDS complications, radiation, and chemotherapy to replenish depleted levels in muscles and improve recovery.

Glutamine supports muscle development and muscle cell volumization.

L-glutamine is used in protein synthesis in cells. Taking glutamine supplements can help gain muscles and improve exercise performance. It is a building block for proteins. It also helps draw salt and water into the cells, keeping them hydrated, fuller, and denser as well. Cell volumization is crucial for growth and repair.

Supplementing with glutamine helps speed up recovery after intense workouts.

Studies show that taking L-glutamine supplements after intense physical exercises reduces muscle soreness and speeds up recovery. When combined with carbohydrates, glutamine decreases a blood marker of fatigue after a high-impact workout.

By continuously promoting protein synthesis and increasing cell volume, glutamine can prevent the chance of injury, reduce muscle fatigue, and enhance muscle recovery. Athletes also use amino acids to boost their immune systems.

Glutamine aids in boosting the immune system.

Glutamine plays a crucial role in your immune system. It is a crucial energy source for white blood cells, certain intestinal cells, and other immune cells.

The body cells require sufficient proteins for optimum function. L-glutamine is one of the primary building blocks of proteins. Studies show that when taken, glutamine boosts health, reduces infections, and decreases recovery time, leading to shorter days in the hospital after surgery.

Using a glutamine supplement can also promote intestinal health.

Glutamine's immune-boosting properties will also improve the health of your intestines. After all, the intestines make up a significant portion of the body's immune system. A lot of intestinal cells have immune functions. There are also trillions of microbes in your intestines that play a role in immune health.

Glutamine is a good energy source for intestinal cells. It also prevents a leaky gut problem by maintaining a barrier between the rest of the body and the inside of your gut. The barrier keeps harmful bacteria from leaving your intestines for your other body parts. It also prevents bacteria infiltration in the course of digestion.

L-glutamine also boosts intestinal cell activity, soothing the tissue and keeping inflammation at bay. As an energy source, it also reduces intestinal spasms.

The benefits of supplementing with a micronized glutamine powder are vast. Prolab Glutamine is available in 400g and 1000g bottles. It is a flavorless, anti-catabolic amino acid that supports post-workout energy repletion, muscle cell volumization, and repair.

When Is The Best Time To Take Glutamine?

Glutamine powder can be used to supplement your diet, weightlifting and exercise routine, sports performance, and overall wellbeing to increase strength and endurance. The best time to take glutamine is outlined below:

Before or after a meal

If you are using glutamine to treat irritable bowel syndrome, take the supplement on an empty stomach an hour before a meal or two hours after.


If you are using glutamine to develop lean muscles, consume it post-workout, around 30 minutes following training. The reason being that at that time, the body readily absorbs more nutrients leading to maximum benefits.

Taking glutamine post-workout promotes muscle protein synthesis. After physical exercises, there are small tears in muscle fibers or tissue. The supplement effectively speeds up healing by helping rebuild muscles and repair damage. Another advantage of supplementing with glutamine is the extra push of endurance the amino acid provides.

In the morning or afternoon

Of course, you can also take the glutamine once before starting your day by blending the powder in your morning beverages or mixing it in your afternoon snack.

L-glutamine supplement dosage, safety, and side effects

In normal quantities, glutamine is not harmful since it is also produced by your body naturally. There's about 3 to 6 g of glutamine in a typical diet. The amount of glutamine an individual requires can vary depending on their specific needs. However, when it comes to glutamine supplements, always take them according to the manufacturer's direction of use to avoid harmful effects.

L-glutamine supplementation is considered safe in most cases; however, some should avoid it. These include people with kidney disease, Reyes syndrome, and certain types of tumor cells. Other people have allergic reactions to the amino acid supplement and may experience nausea, vomiting, hives, and joint pain. In case you experience any harmful outcomes, seek medical attention immediately.

Prolab Glutamine is a dietary supplement for muscle repair, growth, and preservation. Only one teaspoon per day is enough which is about 5g of powder. However, dosages can be increased in case of intense physical workouts or individual needs. Prolab Glutamine is a flavorless micronized powder that can be mixed in water or a favorite beverage.

Glutamine can be obtained through dietary intake too. Incorporating the following foods can also help you obtain good sources of glutamine:
