Glutamine

How does Glutamine work?

Glutamine is an amino acid that might help gut function, the immune system, and other essential processes in the body, especially in times of stress. It is also important for providing "fuel" to many different cells in the body. Glutamine is needed to make other chemicals in the body.

Are there safety concerns?

Glutamine seems safe for most adults and children when taken by mouth, but the potential side effects of glutamine are not known.

Avoid using more than 40 grams of glutamine daily.

  • You are pregnant or breast-feeding.
  • You have severe liver disease with difficulty thinking or confusion.
  • You are allergic to monosodium glutamate (MSG), also known as "Chinese restaurant syndrome."
  • You have mania, a mental disorder.
