L Glutamine

L Glutamine is a non-essential amino acid found in many protein sources. L-Glutamine plays an important role in protein metabolism regulating protein synthesis and stimulating growth hormone production.

As L Glutamine levels fall markedly during intense training, L Glutamine supplementation is important to assist with ongoing muscle growth and post training recovery. L Glutamine is also beneficial for endurance athletes as it can help to reduce the occurrence of muscular cramps.

Uncover the Numerous Benefits of L-Glutamine

L-Glutamine is a supplement that is used for numerous fitness goals. Because of its versatility; this supplement from our Australian online supplements range requires additional clarification. To learn more about L-glutamine and its advantages, please read our information below.

The Science

Scientific studies show that supplementing with L-glutamine can reduce catabolism, which is the breakdown of muscle. The use of an L-glutamine supplement from our Australian online supplements range can also improve protein metabolization in the body.

Studies also show that L-glutamine is one of the most common amino acids in the human body, since more than 61% of skeletal muscle consists of L-glutamine. Getting such a supplement from our range of Australian online supplements could therefore have numerous benefits.

The Specific Functions of Glutamine

To understand the benefits of glutamine, which will be described further in this article, we need to look at the functions this substance performs in the human body. Below, you will find a short overview of glutamine functions.

  • Protein synthesis: science has linked the amino acid glutamine to protein synthesis. The amino acid stops muscle from being broken down, subsequently preventing the catabolism process. The prevention of muscle breakdown also enables the body to get glutamine in other cells of the body.
  • Hydration and cell volume: researchers have found that the use of glutamine can keep the muscle cells hydrated. The substance also helps to maintain the volume of the cell. Therefore, glutamine has an impact on injury recovery and wound healing.
  • Amino acid replenishment: the use of a glutamine supplement is useful for those undergoing rigorous training, because glutamine levels deplete quickly when you do intensive exercise. Supplementing with glutamine can replenish the glutamine you have lost.
  • Increase growth hormones: glutamines can help build muscle by stimulating the production of the human growth hormone. A recent study showed that supplementing with 2 grams of L-glutamine daily can increase the amount of growth hormones by more than 400 percent.
  • Digestion: glutamine plays an important role for digestion and the health of your gastrointestinal system as well. Glutamine maintains the structural integrity of the bowels, which means the amino acid can repair a so-called ‘leaky gut’.
  • Ulcer treatment: glutamine has also shown benefits for problems such as ulcers. A recent study examined the effect of the amino acid on test subjects suffering from ulcers. The results showed that supplementing with 1.6 grams of glutamine daily increased the cure rate for ulcers by 92% over the course of 4 weeks.

The Benefits of L-Glutamine from the Australian Online Supplements Range

Glutamine is not only found in individual supplements, since it can be present in many protein powders as well. The presence of glutamine in quality protein powders is not a coincidence, especially when you consider the fact that glutamine plays a role in protein metabolism, cell volume, catabolism prevention, human growth hormone production and muscle growth. Of course, protein powder from any Australian online supplements range will contain a lower concentration of L-glutamine than an individual glutamine supplement.

The use of glutamine supplements, or a protein supplement containing glutamine, can be good for athletes trying to shed some excess fat while maintaining their current muscle mass. The loss of muscle is common with dieters, which is why many athletes will supplement with a protein powder or glutamine to prevent muscle from breaking down when consuming fewer calories.

Glutamine supplements, or protein powders with glutamine, can also be good for your sports performance. In addition to that, it can also be beneficial for your digestion and your immune system. All these extra benefits accompanying glutamine can also be explained by the versatility of amino acids.

There are numerous amino acids that can be obtained through food and supplements, but also amino acids that are created by our own body. These amino acids tend to have numerous functions, which is why many athletes tend to supplement with many different amino acids to take advantage of all the benefits these substances can deliver.

How Much Glutamine Supplement Do I Need?

The amount of glutamine you will need can depend on numerous factors; this includes your age, activity levels and your fitness goals. The average body builder needs approximately 10 to 15 grams of the supplement each day, which is usually spread over the course of the day with a serving of 5 grams.

When you take a protein supplement already, it is advised to check if your protein supplement already contains glutamine. When you do not include glutamine from your protein powder in your calculations, it could lead digestive problems.

Athletes who are unfamiliar with supplements, or just starting to work out after a period of inactivity, should ask a personal trainer or nutritionist for advice on their supplements. With the help of a trainer, health professional or nutritionist, you can make sure you are consuming the right amount of glutamine.

Does Glutamine Have Any Known Side-Effects?

Studies have not found any side-effects accompanying the use of glutamine supplements. Scientists and researchers believe the absence of side-effects can be explained by the fact that glutamine is naturally present in the body.

Even though glutamine does not have any reported side-effects, taking too much of the supplement can cause some digestive-related problems. Athletes who consumed too much of the supplement have reported an upset stomach and other problems related to digestion. Therefore, always make sure you stick to the dose recommended by the supplement manufacturer, health professional or nutritionist.


Glutamine is a versatile amino acid that can have numerous benefits for beginning as well as experienced athletes. It is best suited for bodybuilders, since the amino acid has a clear effect on the muscle building abilities of athletes using this supplement.
