Top 10 Glutamine Supplements To Help Build Muscle & Enhance Recovery

What does Glutamine do?

Glutamine plays the crucial role of increasing an individuals ability to build muscle, improve in strength training, and enhance an the body’s ability to burn fat at a faster rate. Glutamine belongs to the L-Amino Acid group and is a building block of protein.

This amino acid is naturally produced by the human body when we eat foods such as fish, eggs, chicken, vegetables, and wheat products. The body requires rather large doses of Glutamine; concentrations which cannot be achieved by food alone. This is especially true for weightlifters. The body building function of Glutamine makes it all the more necessary for men as well as women to increase intake through supplementation.

Supplementation of Glutamine for Bodybuilding

For the body to reach the required levels of Glutamine needed for bodybuilding purposes, you’ll need to supplement. Glutamine helps with protein synthesis,which is essential for rebuilding muscle tissue after a rigorous workout, thus it can help reduce recovery times which means you’re back in the gym and ready to tear up those muscles all over again.

How Does Glutamine Work?

Glutamine is a non essential amino acid. This means that the body has the inherent ability to produce it naturally, however as we age, it becomes harder to produce an ideal amount. This amino acid is brings a variety of benefits to the human body as it facilitates healthy muscle tissue development and muscle repair.

It is also the preferred energy source of tissues in the digestive system and the immune system. Glutamine is also a great source of energy at a cellular level. A healthy dose of Glutamine gives you the ability to use high levels of energy, which is obviously needed for strength training. Glutamine also promotes gastrointestinal health. Glutamine acts as an essential neurotransmitter to our brains as it enhances one’s mood. In other words, this stuff is very important to the body for a plethora of reasons.

Glutamine is involved in gene regulation. It acts as the energizer for rapidly dividing cells, as it is a major building block of cells. Glutamine also acts as immune system booster as it promotes the division of immune cells when infection invades the body. Threats come in many forms such as colds, cough, fever, flu and other viruses.

How to Use Glutamine

The best time to take Glutamine supplements is during mornings and evenings after meals. The recommended dosage for intake of Glutamine is between 5 and 10 grams daily. There are various forms of supplements available, which we’ll be taking a look at shortly.

Benefits of Glutamine

Glutamine is considered to be a stable and effective supplement that aids bodybuilders in achieving their ultimate mission: massive gains. For many serious lifters, it’s already a staple in their supplement cabinet. Although Glutamine is categorized as non-essential, it becomes essential when we put our bodies through rigorous training.

Athletes find it a necessity to take in high doses of Glutamine as they regularly undergo long periods of high-stress through extensive physical exertion on a regular basis.

Aside from being able to replenish lost energy, Glutamine has other benefits including:

  1. Glutamine is an answer to protein deficiency,

  2. Glutamine enhances the immune system after intense exercise,

  3. Glutamine increases the rate of natural growth hormone production,

  4. Glutamine replenishes vitamins and minerals post-workout,

  5. Glutamine is essential for optimum growth and crucial to liver functions,

  6. Glutamine is an essential energy source of body tissues, particularly the muscle tissues, immune cells, and the gastrointestinal tract, and

  7. Glutamine greatly enhances recovery and recuperation after intense training.

Top Ten Glutamine Supplements

1. Glutamine Powder by Kaged Muscle

Glutamine Powder

Glutamine is the most abundant amino acid in the human body. Though not considered an “essential” amino acid, it is without question a “conditional” amino acid. There are 3 unique yet interwoven factors that can dramatically increase demand for glutamine within the human body; these include enhanced muscle exertion and recovery, immune support and gastrointestinal health.

Stress is the ultimate enemy of the human mind and body. Glutamine is no exception to the ravages of stress. The stress hormone cortisol is “catabolic” leading to breaking down the body and tissues. Whereas, the goal is an “anabolic” building mode. No matter how chill and no worries attitude you may have, living in the modern helter skelter world wears down even the most easy-going person. Remember stress is not just a mental state of mind, lack of sleep, long work hours or a hostile work environment, relationship issues, a cold or flu and even food allergens/intolerances are all perceived as enemies of the “state of thriving” not just surviving.

L-glutamine plays a very important role in protein metabolism, and it appears to be a very important nutrient for body builders. When supplemented, it may help body builders reduce the amount of muscle deterioration that occurs because other tissues that need glutamine will not rob the glutamine stored in the muscle cells.

6. Glutamine by Beast Sports Nutrtion

Beast Sports Nutrtion Glutamine

Glutamine is the most abundant, naturally occurring amino acid in the human body. It constitutes more than 60% of the amino acids found in skeletal muscle and is the most concentrated free amino acid in the blood. Glutamine can be used as a building block for making more proteins (i.e. muscle), a direct energy source for making ATP (the energy currency of the body) or as a precursor for the formation of glucose in the liver.

While skeletal muscle tissue is responsible for synthesizing ~90% of the glutamine found in the body, the most eager consumers of glutamine are the gut, kidneys and immune system. Glutamine is, therefore, vital for variety of biochemical functions ranging from protein synthesis to intestinal permeability, optimal immune function and the regulation of the body’s acid-base balance.

Importantly, glutamine is considered a conditionally essential amino acid meaning it can be made within the body but requires intake from food or supplements under high stress conditions such as intense exercise, food restriction, injury and illness.
