L Glutamine is an amino acid that is naturally found in the human body. It is not considered to be inherently essential to the human body, but it can become one in situations that require extended effort or when the gastrointestinal system is facing issues.

This product claims to improve the body’s metabolism, strengthen the immune system, improve focus capacity and even fasten the liver’s recovery rate. While not all of these claims are medically proven, the supplement is still very popular, particularly among people performing sports. Many companies are currently manufacturing this product, either as a stand-alone supplement or as a compound with other substances meant to improve the body’s general condition.

Sports enthusiasts, professional athletes and people trying to lose weight are sure to appreciate L Glutamine, due to the accelerating effect it has on metabolism. People that suffer from gastrointestinal issues can also benefit from the intake of this amino acid, as it keeps the intestinal lining healthy.

Synopsis

1) L Glutamine at a Glance

The active ingredient in L Glutamine is Glutamine, one of the 20 amino-acids that are naturally encoded by the standard genetic code. This substance has undergone research for the past 10-15 years, with conclusive result regarding its positive effects on the human body.

A supplement of choice for bodybuilders and weightlifters, Glutamine aids the body in moving nitrogen to where it is most needed, rushing metabolism and increasing energy levels. This effect proves useful for people practicing sports, as well as individuals that need an extra boost in their daily activities.

Another medically attested use for Glutamine is in postoperative patients. The supplement has consistently shown to be useful in recovering from injuries, trauma, and particularly helpful in people recovering from treatment-related side-effects of cancer or that have undergone abdominal surgery.

There is a large amount of debate regarding the effect of Glutamine on the liver; while it is generally considered to improve the liver’s regenerative capacity, there has been some evidence that it might actually prove harmful to people already suffering from liver disease.

Aside from liver conditions, there are no reported negative interactions for this product. It is considered safe for everyone regardless of age or gender, but caution is still advised. If you begin experiencing any undesired effects, discontinue the use of the supplement and consult a doctor.

Out of L Glutamine’s many uses, the main one is that this amino acid is responsible for moving nitrogen around in the body to the locations that need it. L-Glutamine supplements are claimed to help the body increase energy levels, to provide more stamina, and to help aid with the recovery process from various health concerns. It is also claimed to be a way to keep the mind functioning well with additional focus and alertness.

There are many reports that L-Glutamine can boost the immune system and regenerate faster from other health problems. One of the reasons a person might want to take this amino-acid is that it supposedly lowers stress levels and repair damaged cells simultaneously. Notorious coffee or alcohol drinkers, as well as smokers, will feel at ease because L-Glutamine provides a faster rate of recovery for the liver.

The debate continues though about how effective L-Glutamine supplements are. Some experts believe that they aren’t nearly as effective as what the body can produce on its own, while others deny such statements. The value of the product depends on each.
