How it works

Brain fuel

  • In the brain glutamine is converted into glutamic acid – which is essential for brain functioning.
  • It also increases the amount of GABA, which is needed to sustain proper brain function and mental activity.

Gut repair

  • Glutamine assists in maintaining the proper acid/alkaline balance in the body, and the maintenance of a healthy digestive tract.

Muscle repair

  • Glutamine is found in large amounts in the muscles and is readily available when needed for the syntheses of skeletal muscle proteins.
  • It helps to prevent any muscle wasting that can accompany prolonged bed rest and diseases like cancer and Aids.


  • Glutamine preserves glutathione in the liver and protects the organ from the effects of alcohol.
  • Decreases sugar cravings and the desire for alcohol.


Advise patients with Cirrhosis or Hepatic encephalopathy to avoid taking Glutamine supplements. Due to it being metabolised into Ammonia which might worsen their condition.

Theoretically, Glutamine, which is metabolised to the excitatory neurotransmitter glutamate, might antagonise the anticonvulsant effects of medications taken for epilepsy and should be taken with caution.

Great for little metabolism boost

Healing is a journey and individual. I’ve struggled with my metabolism for a long time and winters are especially tough - I feel small changes since I’ve been taking l-glutamine.
The body has the ability to restore - and sometimes a little nudge is all it needs. Amazing product and taste much better than the ones I bought on amazon previously.
