Best Glutamine Powder Supplements

Also known as l-glutamine, glutamine is one of the most important supplements for bodybuilders, power lifters and others involved in intense sports or exercise. Yet it is the most underrated. We shall look at the importance of this supplement as well as the best glutamine powders.

Adequate protein intake is essential for muscular growth, but not all protein is created equally. Protein is made up of amino acids. Amino acids are often referred to as the building blocks of proteins.

There are 22 amino acids, 9 of which are considered essential because the human body cannot produce them on its own. Glutamine, also referred to as l-glutamine, is actually the most abundant of the amino acids. So why do you need to supplement it?

Under normal circumstances, the body is able to produce plentiful supply of glutamine, which is stored primarily in the muscles and secondarily in the lungs. This places glutamine under the umbrella of non-essential amino acids. Note the words “normal circumstances”.

However, when placed under extreme stress by disease, injury or extreme exercise, glutamine stores are depleted and the body cannot keep up with the demand. This can result in a catabolic state (muscle loss).[1] During these times, glutamine is considered to be a conditionally essential amino acid.

Various medical conditions, including diseases and injuries, as well as certain infections can also lower glutamine levels. Intense bouts of exercise have the same effect.

Chronic stress, which leads to an increased production of cortisol, also reduces glutamine in the body. Glutamine supplements would be helpful for a person falling into any of the above categories.
