L-Glutamine is the most abundant amino acid in our bodies, and while we can synthesize it from other amino acids, it’s considered ‘conditionally-essential’. This means under certain conditions such as strenuous exercise demands or disrupted digestive or immune health, we may need to consume additional sources to meet our needs.

L-Glutamine also serves as a primary fuel source for enterocytes – the cells that make up the lining of our digestive tract – as well as immune cells, so adequate glutamine is critical for good health.

The L-Glutamine Story

There are several reasons active you may want to consider adding L-Glutamine to your supplement routine.

When we break down muscle through exercise, we raise our demands for L-Glutamine. If we get sick or experience excess inflammation in our digestive tract, our L-Glutamine requirements can increase.

Formula Highlights

  • Pure L-Glutamine powder
  • No flavors, sweeteners, or colors added
  • Odorless, flavorless, and tasteless so it?s easily incorporated into foods or beverages
This amino acid promises much — for mind, muscle and immunity. Can taking glutamine really help you?
Whether you like to cook, sew or catch fish, it’s always fun to learn about trendy accessories for your favorite hobby. If your hobbies include working out and eating right, the latest gizmos consist of nutritional accessories – like glutamine (L-glutamine or glutamate), a nonessential amino acid, naturally occurring in the human body and brain, that has become a very popular supplement in athletic circles.
You may wonder why a nonessential anything would become a popular supplement. Well, to start, the term “nonessential” is somewhat misleading. It doesn’t mean unimportant. It just means that your body can build a nonessential amino acid from other food sources. The essential amino acids are those you have to eat, because your body does not produce them. But just because you can manufacture glutamine does not mean you can live without it. Especially since exercise can deplete blood glutamine to a point that compromises your immune system and makes you more susceptible to colds and other infections.
Glutamine represents about 60 percent of all the free amino acids in your system, making it the most important bodybuilding material coursing through your veins. It provides fuel for your brain, muscles, intestinal lining and white blood cells. Skeletal muscles manufacture most of it, along with some help from your lungs and brain. On the other hand, your intestine, kidneys and immune system consume loads of this amino acid without producing any. So, during stressful activities like intense exercise, the balance of glutamine shifts from your big, bulging muscles to your needy gut and immune system. This transfer depletes your muscle tissue, and can eventually create an overall deficit in blood plasma levels.
Research shows glutamine supplements promote a positive nitrogen balance in muscle tissue and create an anti-catabolic effect that may prevent some of the cellular damage associated with intensive training.  This amino acid promises much — for mind, muscle and immunity.

Frequently Asked Questions

Can I use pills instead of powder for L-glutamine?

L-glutamine can also be found in pill or capsule form, but the powder form is perhaps easiest to incorporate through a wide variety of food or beverages.

When should I ideally consume this?

Timing isn?t critical as long as you?re supporting your daily L-Glutamine needs, whenever convenient for you.

How much glutamine should I be using daily?

5 to 15grams per day (or one to three scoops of Life Time Fitness?s L-Glutamine) is a good general recommendation.

Don?t we get glutamine from protein powders and amino acid complexes? Why would I use additional L-glutamine?

Yes, L-glutamine is a common amino acid in other protein sources, including protein powders, but additional pure L-glutamine has shown to be beneficial in addition to dietary or supplemental protein sources.
