L-Glutamine is a non-essential amino acid. Thus, we produce it naturally through our muscles, brain, and lungs. However, during periods of intense physical stress, illness, or intense exercise, the need for L-Glutamine can surpass production.

This deficiency can lead to muscle breakdown and hinder optimal performance. Hence, L glutamine supplements are necessary for certain individuals.

Amino Acids and the Role of L-glutamine in Our Body

Amino acids maintain a healthy body by supporting various functions. They are the building blocks of protein. 

One such crucial amino acid is L-Glutamine, which plays a fundamental role in your overall well-being. L-Glutamine is one of the most versatile amino acids.

It serves as an essential fuel for various cells in the body. These include:

  • Immune cells
  • Intestinal cells
  • Brain cells

This amino acid helps maintain the structural integrity of the gut function. Thus, it ensures that harmful substances do not enter the bloodstream.

Also, taking L-Glutamine supplements aids in protein synthesis, muscle repair, and post-workout recovery. That is why the L-glutamine benefits are praised by the highest industry professionals.
