  • Provides immune support.
  • Protects muscle tissue.

Of all the amino acids in the blood stream, Glutamine is the most plentiful. Certain types of increased stress deplete glutamine levels (e.g., cancer, burns, or intense exercise) and can demand supplementation.

Glutamineā€™s main bodily function is to ward off infections and diseases. Low levels of glutamine can also negatively affect the intestines. This added stress to the body causes the release of cortisol, multiplying the depletion of the storage of glutamine. Glutamines essential role in the immune system makes any serious drop cause wound healing to slow down. Supplementing with glutamine helps the body increase immunity, thereby minimizing infection and boosting the healing process.

Suggested Use: Take 1 to 6 capsules per day between meals or after a workout, or as directed by your qualified health care consultant.

Notes: Glutamine is the most abundant amino acid in the human body and is involved in many metabolic processes. Skeletal muscles are the primary sites of glutamine concentration. Glutamine protects muscle tissue and supports immune function during periods of immune and muscular stress.* Glutamine supplementation supports protein synthesis as well as the rate of glycogen production (by serving as a carbon donor).* Glutamine is also a major source of fuel for enterocytes (intestinal cells) and hence supports the integrity of the intestinal lining as well as assists in nucleotide synthesis by lymphocytes.*
