What Is Glutamine?

Glutamine makes up 61% of muscle tissue. That makes it the most dominant amino acid in your muscles. In addition, glutamine is a conditionally essential amino acid. That means that even though your body makes it, glutamine is depleted under certain conditions. Therefore, it needs to be replenished by diet and supplements. 


You have no doubt heard the term "positive nitrogen balance". It means the body is in a state of positive protein balance or an anabolic state. Glutamine is 19% nitrogen, which means it’s a primary supplier of nitrogen to your muscles. Nitrogen is a key component of protein that’s used as a measure of total body protein. Therefore, glutamine is essential for helping to maintain a state of muscle growth. (1, 2)

Additional Benefits Of Glutamine 

The body’s demand for glutamine increases significantly during intense training sessions and other times of physical or emotional stress. This includes such things as injury and illness, and even pre-contest dieting for a bodybuilding contest. Plus, glutamine plays a role in protein synthesis and prevents the breakdown of muscle protein. Clinical research also suggests that glutamine supports post-workout recovery. Not to mention, it supports the metabolism of BCAAs, the formation of glucose, and neurotransmission. Finally, it supports immune system function and health. One reason for this is that lymphocytes and macrophages cells use glutamine as a key source of fuel. This means the demand for glutamine increases when the immune system undergoes stress. (3,4,5, 6)


NOW L-Glutamine Powder comes in an unflavored powder. Add it to your pre-workout, intra-workout, or protein shake. Of course, you can also use it as a standalone product.
