L-Glutamine promotes gut and brain health, muscle growth, athletic performance and helps balance blood sugar levels

L-Glutamine - Promotes gut and brain health. Also improves muscle growth and athletic performance


Benefits of L-Glutamine
  • Promotes gut and brain health
  • Improves muscle growth and athletic performance
  • Helps balance blood sugar levels
  • Promotes weight loss
  • Helps maintain optimal immune function (especially under times of heavy stress load)
  • Improves mental alertness
  • Enhances energy levels
  • Promotes an acid-alkaline balance, helping to maintain a healthy digestive tract

Glutamine is one of twenty amino acids that is used to manufacture protein and is one of the most abundant in the bloodstream. It is a conditionally essential amino acid that is involved in many metabolic processes. Glutamine can be produced in the body but also acquired through diet.

 However, it can become depleted during excessive and intense exercise, or prolonged stress. It promotes gut and brain health, improves muscle growth and athletic performance. It also helps balance blood sugar levels and can help with weight loss.

 Glutamine has also been seen to improve mental alertness, increase energy levels, promote weight loss, protect the body from stress, promote an acid-alkaline balance in the body, so, therefore, a healthy digestive tract. It is a fuel source for the immune system, a precursor to GABA (gamma-aminobutyric acid), and is needed for a healthy gut, specifically ‘leaky gut’, which is a major cause of chronic inflammation.  

 As with most amino acid supplements your body needs vitamin B6 (pyridoxine) as a cofactor to ensure correct amino acid metabolism.


  • Most amino acids come in two forms; D- or L- (such as L-tyrosine or D-tyrosine). The D-amino acid is a mirror image of the L- amino acid - in other words the D- form is a backward image.
  • Both can be taken. However, the L- form is preferable as it is the exact image of the amino acid in its natural form found in the body. The L- form is considered the more effective for overall human health.

As a dietary supplement, adults take one tablet, one to three times daily between meals or as directed by a Healthcare Professional.

Store in a cool, dry place, away from direct light.

Do not exceed the recommended daily dose.

Keep out of reach of young children.

Children, pregnant women, and women who are breastfeeding should consult their doctor before use.

Nutritional supplements should not replace a varied and balanced diet and a healthy lifestyle.

Check with simultaneous intake of medicines with your physician or healthcare professional. No long-term use without professional advice.


If you have a monosodium sensitivity, use glutamine with caution as the body may metabolise glutamine into glutamate. If you are taking seizure medications, consult your doctor before use
