• L-Glutamine



L-Glutamine has been a constant staple in the wellness community, for its positive effects on the body’s nitrogen levels.

L-Glutamine is the most abundant amino acid in your muscles (over 61% of skeletal muscle is Glutamine!), and is used in large amounts by your body. During intense training, or times of stress, Glutamine stores are depleted, and supplementation may be required to aid in immune fortification, muscle development and maintenance. 

L-Glutamine is effective for those who are training and wanting to preserve muscle and strengthen their immune system.

Frequently Asked Questions


L-Glutamine is an amino acid, used by the body in abundance for muscle recovery, growth & maintenance, and Immune Support.

Despite it being one of the most abundant aminos in your body, L-Glutamine quickly becomes depleted during times of stress, requiring supplementation to return your body to normal glutamine levels.


This plant-based amino is crafted using a special fermentation and filtration process, eliminating the risk of impurities and delivering a premium, pharmaceutical-grade supplement. This conditionally essential amino (required by the body in large amounts despite the body’s ability to produce it naturally) can become essential in times of physical stress & intensity and may assist in reducing your body’s muscle wasting (catabolic) state.
Our 100% pure L-Glutamine is ultra-fine and free form, giving it improved bio-availability and absorption.

L-Glutamine from Protein Supplies Australia

Service: Excellent I typically order on the weekend and the product is on my doorstep by Tuesday afternoon.
The Product: This is a excellent product sourced and produced with natural ingredients. Once a year I will stop taking any vitamins and suppliments and I will take a 3 month course of L-Glutamine.
During this time on L-Glutamine I am still able to work and continue training without feeling fatigued.
I have been doing this for several years now and I can say with confidence that this product works . I would suggest to any young athletes taking suppliments that they research as to what there suppliments are actually made from.
Protein Supplies Australia produce a high quality product sourced from natural ingredients.
