  • Free amino acid in the human body.
  • Brain fuel.
  • A building block of protein.
  • Necessary for proper immune function.

L-Glutamine provides a significant amount of this nonessential amino acid. Amino acids are referred to as the building blocks of protein, required in the building and maintenance of muscle tissue within the body. The body normally obtains adequate amounts of this abundant amino acid; however, during periods of heightened physiological stress, protein is broken down at an accelerated rate due to an overall higher body metabolism and the interference in its absorption caused by cortisol, a stress hormone. Under these conditions, it may be impossible to consume enough glutamine. Inadequate amounts of glutamine can manifest as delayed wound healing, inflammation and susceptibility to injuries.

Suggested Use: 1 tablet daily.
