Kyowa Quality L-Glutamine is an amino acid obtained by biofermentation on a plant substrate, a process that guarantees remarkable purity without any recourse to animal materials or chemical solvents. This manufacturing method meets the strictest pharmaceutical-grade standards and ensures consistent composition from batch to batch. The Kyowa Quality label, developed by the Japanese laboratory Kyowa Hakko Bio, is a world reference for ultra-pure amino acids. This form of glutamine suits athletes, vegetarians and anyone seeking a supplement free from allergens and GMOs.

L-Glutamine is the most abundant free amino acid in the human body. It is involved in protein synthesis, muscle tissue repair after intense exercise, and maintaining the integrity of the gut lining. During periods of physical or mental stress, the body draws heavily on its glutamine reserves to fuel muscles, the liver and immune cells. Athletes practising strength training or endurance sports often notice improved recovery and reduced soreness. Glutamine also serves as the main energy source for enterocytes, the cells of the digestive tract, helping reinforce the gut barrier against unwanted agents.

With 300 vegetable capsules per bottle, this format is an economical choice for an extended course. At 4 capsules per day (3,000 mg of pure L-Glutamine), the bottle covers more than two months of uninterrupted daily supplementation. Each capsule is made of pullulan, a plant-based shell naturally derived from tapioca, with no excipients, additives, colourings or preservatives. The bottle is also designed with an eco-responsible approach, free of bisphenols and phthalates.

The recommended dose is 1 to 4 capsules per day, taken with a meal and a large glass of water. For athletes, taking it after training supports muscle recovery. For gut lining support, spreading the intake throughout the day may be considered.

If you are on medication or have known kidney issues, seek advice from a healthcare professional before starting supplementation.

Is Kyowa Quality L-Glutamine suitable for vegetarians?

Yes, this glutamine is obtained through biofermentation on a plant substrate, with no animal-derived ingredients involved in its manufacture. The capsules are also 100% plant-based, made of pullulan from tapioca.

What is the difference between this L-Glutamine and a standard one?

The Kyowa Quality label certifies superior purity and traceability compared to standard glutamine. The biofermentation process eliminates contamination risks often found in conventional production, resulting in better digestive tolerance and consistent efficacy batch after batch.

When should I take L-Glutamine to optimise sports recovery?

For muscle recovery, the ideal timing is within 30 minutes after physical effort. Outside training periods, taking it with a meal remains appropriate to support gut balance.
