L-Glutamine (Kyowa Quality®) Powder by RawSeries is a vegan food supplement in powder form, based on Kyowa Quality® plant-fermented L-glutamine.
Glutamine is a non-(conditionally) essential amino acid, and constitutes the main component of the amino acid pool of the human organism, especially of the musculoskeletal tissue, where it constitutes up to 60% of the total intramuscular amino acid concentration (Cruzat et al., 2018).
L-Glutamine (Kyowa Quality®) Powder is derived from plant sources and is 100% suitable for vegetarians and vegans.
At HSN we strive to improve every day. In our research process to develop new products and optimise the products already available, pursuing the highest quality, we discovered the company Kyowa Hakko.
Kyowa Quality® was the company that developed an innovative method for obtaining amino acids. It began producing them from plant sources, which undergo a natural fermentation process to extract the product you can now buy.

This process allows amino acids to be obtained through sustainable production methods, of the highest quality and certified purity. Free of genetically modified organisms, without elements of animal or human origin; suitable for vegetarians and vegans.
HSN brings you L-glutamine with 100% Kyowa Quality® certified raw material, a real revolution in the food supplement market.
L-Glutamine (Kyowa Quality®):
Kyowa Quality® ingredients meet the requirements of all major official pharmaceutical monographs:
- Japanese Pharmacopoeia (JP).
- United States Pharmacopoeia (USP).
- European Pharmacopoeia (EP).
Kyowa has been a pioneer by being the first company to develop the fermentation technology that enabled the production of amino acids on an industrial scale for the first time.
From seed crop, completely free of animal and GMO ingredients, and through a plant-based fermentation process.
Pure ingredients are produced with 100% Kyowa Quality® assured.
L-Glutamine powder mixes easily into any liquid of your choice (water, milk or juice; mainly).
The fine powder of glutamine facilitates its homogeneous dispersion and dissolution.
Vegetable-fermented glutamine produced under KQ trademark standards is tasteless.
It can be used in conjunction with other products, such as your Evowhey 2.0 after training protein shake, without altering its taste.
L-Glutamine (Kyowa Quality®) powder doesn't alter the taste of mixtures.
Glutamine has a neutral, slightly acidic and sweet taste.
