Glutamine is an amino acid that's typically used for recovery. It’s also involved in protein synthesis and acts as an anti-catabolic. If you’re not using glutamine, the time has come to add it to your program. Why? Because this impressive amino acid can help you reach your goals. But don’t add just any glutamine supplement, go with the best - 5% Nutrition Core L-Glutamine 5000! 

What Is Glutamine?

Let’s look at what exactly this amino acid is and what it does. Glutamine is a conditionally essential amino acid. What does that mean? Under normal circumstances, the body makes it. But, stressful conditions deplete glutamine. This includes the physical stress of working out. Therefore you should replenish it from your diet and supplements. 


Glutamine makes up 61% of your skeletal muscle tissue, making it the most dominant amino acid found in your muscles (BCAAs are next). In addition, glutamine is 19% nitrogen, which is an important component of protein. Glutamine is also the primary transporter of nitrogen to your muscles. Nitrogen can be measured to determine total body protein. It’s likely you’ve heard the term "positive nitrogen balance". What does that mean? Put simply, it means the body is in an anabolic state or a state of positive protein balance. (1, 2)

The Benefits Of Glutamine 

As noted, your body’s need for glutamine increases during times of physical stress, such as intense exercise. Also, glutamine plays a role in protein synthesis and acts as an anti-catabolic by helping to prevent the breakdown of muscle protein. In addition, studies show that glutamine supports post-workout recovery. Further, it supports the metabolism of BCAAs and supports the formation of glucose. Finally, it supports a healthy immune system because the lymphocytes and macrophage cells are able to use glutamine as a source of fuel. This is considered a form of stress that depletes glutamine. That’s one more reason to add 5% Nutrition Core L-Glutamine 5000 to your program. (3, 4, 5, 6)

5% Nutrition Core L-Glutamine 5000 Ingredient Profile

Now that we know what Glutamine is and what it does, it’s time to look at the ingredient highlights of Core L-Glutamine 5000. 


L-Glutamine - 5000 mg

One serving provides 5 grams of L-Glutamine. The key feature that sets Core L-Glutamine 5000 apart from those other companies' Core-style formulas is our use of supporting ingredients. The typical "core" type products use only a single ingredient. Not 5%! We go beyond the competition by adding 1-2 supporting ingredients. In this case, we’ve added 2 extra ingredients: L-Alanine and N-Acetyl-L-Glutamine.


L-Alanine - 250 mg

This is a non-essential amino acid that is made by your body. It is synthesized by your muscle cells from lactic acid. When it’s combined with glutamine, it plays a role in the metabolism of amino acids. Also, alanine supports normal levels of blood sugar, thereby helping to ease fatigue. (7)

N-Acetyl-L-Glutamine - 250 mg

This is glutamine combined with an acetyl group. What does this do? Primarily, it significantly improves absorption. By adding these 2 impressive ingredients, we have created a state-of-the-art L-Glutamine formula.
