http://professionalwhey.com Glutamine is the most abundant single amino acid in the blood and in the intracellular free amino acid pool (most abundant amino acid in muscle tissue).

Glutamine concentrations fall remarkably after training within as little as 30 minutes, and remain low until complete recovery, up to as long as 5 – 7 days, resulting in decreases in strength, stamina and recovery.

What does Glutamine do?

Glutamine supplementation not only stimulates immune function, but decreases inflammation and protects muscle cells from the damage caused by hard workouts.[1] Glutamine helps to support the immune system by keeping the health of the gastrointestinal tract high which has the greatest effect on positive immune functions.[2],[3],[4],

Increases Nitrogen

Its structure contains two nitrogen atoms which make it the primary transporter of nitrogen, as it transports 35% of the nitrogen that gets into the muscle cell, which can equate to anabolic muscle growth. But lets not jump the gun just yet!

Anti-Catabolic & Immune Boosting

Following an intense workout, Glutamine levels in the body can fall by as much as 50% and remain low until recovery is completed. This is because an intense workout will take nitrogen carrying Glutamine from muscle tissue and use it to help with recovery and immune function. This fall in Glutamine creates a catabolic environment for muscle tissue.

Increased Protein Synthesis

Therefore by taking a pre and post workout Glutamine supplement, athletes and body builders can minimize the breakdown of the Glutamine already present in the muscle tissue and keep nitrogen levels high which allows for improved protein synthesis.[5]

Glutamine only works because it is used to feed the gut and the immune system. This enables the muscle Glutamine to remain high, keeping nitrogen levels and preventing muscle cells from breaking down and going into a catabolic state.[6]

Growth Hormone Release

In addition, research has demonstrated the ability of Glutamine to dramatically increase Human Growth Hormone (HGH) levels indeed, a meaningful increase was found from as little as 2 grams of free-form L-Glutamine.[7]

Increased Glycogen Uptake

Finally, Glutamine taken after exercise can increase the availability of glycogen, thus promoting increased accumulation of muscle glycogen a key factor in recovery from one workout to the next.[8],[9],[10],[11],

Glutamine is typically used by:

Weight-lifters, bodybuilders and other strength athletes

Power athletes (Rugby players, Field athletes, Boxers etc)

Endurance athletes wanting to build muscle or increase strength

Anyone wanting to improve the health of the intestinal tract and increase immunity.
