Would you consider taking a muscle building supplement that even Dwayne Johnson a.k.a “The Rock” have in common? Yes, you heard it right, even Dwayne Johnson supplement himself with 15g of L-Glutamine and Hydrolyzed whey for the faster post-workout recovery (1).
Glutamine is one of the most abundant and important amino present in the body, it’s not just proven to be beneficial for promoting muscle recovery but also proven good for immune and gut health(3).
L-Glutamine is also called as “Conditional” Amino acid (2), its conditional because your body can produce it on its own but under certain conditions (illness, injury, intense workout) your body’s need of Glutamine surpasses your body’s capability to produce it.
Before we discuss the best L Glutamine supplement available in the market its important to know the difference between Glutamine(4) and L-Glutamine.
Is L Glutamine the same as Glutamine?
Glutamine is a conditional amino acid that is available in two different forms, L-glutamine and D-glutamine.
Both forms of glutamines are almost identical but have little different molecular structure (5).
Researchers found, while L-Glutamine serves as a crucial building block of protein, D-Glutamine had no practical effect on protein synthesis.
In simple words, It doesn’t matter whether you buy a Glutamine supplement or L-Glutamine supplement, reputed brands are going to provide you “L-Glutamine” only.
You don’t really need to bother about product name being “Glutamine” or “L-Glutamine”

Benefits Of Glutamine
Still wondering, whether you should stack a glutamine supplement in your inventory? Have a look at the benefits L-Glutamine has to offer.
Glutamine is also known as a conditionally essential amino acid, this means that your body has the capability to produce it on its own, but sometime you might require to supplement it because of illness or body’s heavy requirements.
During the stage of peak stress, L-glutamine might be your best friend to support your muscle mass and endurance. Let’s have a look at the top benefits of glutamine.
One of the greatest impact of glutamine is on your immune system, it acts as a critical fuel source for white blood cells and other antibodies(11). Your body’s requirement of glutamine elevates in the state of illness and it might breakdown protein if sufficient glutamine is not provided which makes it very necessary to supplement with glutamine in a state of illness (8). Supplementing with glutamine may result in fast-tracking your recovery process after illness or injury.
Better intestinal health
Its not just good for the immune system and muscle support, glutamine plays a vital role in maintaining intestinal health as well. Glutamine helps in preventing harmful bacteria and other toxins from transporting from your intestines into the rest of your body (9).
Glutamine act as a energy source for your intestinal cells too, and regulates the number of healthy gut bacteria for proper digestion. Millions of people are affected by Leaky Gut Syndrome, glutamine is especially helpful for those people (12).
Prevents muscle breakdown
L-Glutamine is a building block of protein and plays vital role in muscle development.
L-Glutamine is found specifically beneficial to protect the muscle from breakdown, because of the number of reasons.
A study conducted on the effect of glutamine on muscle development, at the end of study there was no considerable difference found in the muscle development of group who was supplemented with l glutamine and the placebo group.
So, if you are looking to take glutamine for new muscle tissue, you might be disappointed. But if your intention is to eliminate muscle loss while intense workout or to strengthen the immune system then supplementing with L-Glutamine is surely a great choice.
Remember, preventing muscle breakdown plays big role in muscle development and strength gain.
How much l glutamine to take?
A recommended dose can be between 10-15 grams of glutamine per day is a good enough, for serious athletes it might go upto 25-30 grams.
Although long term supplementation of glutamine is not shown to cause any harm to the body, it’s recommended to add Vitamin B12 to control glutamine levels in the body.
