Glutamine Supplements

For a solution that can support your muscle recovery, improve your intestinal health, boost your nutritional intake and optimise your immune function, glutamine supplements might be your key.

Glutamine is the most abundant amino acid in the body. It is a non-essential amino acid that is one of the building blocks for making proteins and can be sourced both naturally from your diet and created by your body when required. Glutamine supplements are some of the most effective Amino Acid Supplements and are often referred to as a ‘conditionally essential amino acid’.


If you’re overwhelmed by the amount of amino acids supplements available, and have no idea what to choose between BCAAs, EAAs, Beta-Alanine or Glutamine, we’ll explain the difference.

BCAAs differ from EAAs as they contain differing rations of Leucine, Isoleucine and Valine, while EAAs contain the 9 essential aminos, including the 3 BCAAs that the body can’t produce alone. Beta-Alanine is a non-essential amino acid that plays a role in muscle endurance during training, while Glutamine works by reducing muscle soreness and supporting recovery after exercise.

Among the best products, Evolve L-Glutamine is a natural formula that supports muscle recovery, immune function and digestion. This form of glutamine is 100% natural rice fermented and is made using a natural fermentation process. ATP Science’s L-Glutamine is another effective solution that is vegan-friendly, GMO-free, additive-free and has zero impurities.
