Available in two versions: the standard RawSeries version and the RawSeries Kyowa Quality® version, certified by the Japanese company Kyowa Hakko Bio, a pioneer in the development of industrial-scale amino acid fermentation technology and a global benchmark for amino acid quality and purity. L-Glutamine is micronized for maximum solubility and rapid dispersion in water, milk, or any drink without clumping. Suitable for vegan and vegetarian diets. Dose: 5g\/day.\u003c\/p\u003e\n\u003ch2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eBenefits\u003c\/h2\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eL-Glutamine: the most abundant amino acid in the body with a central role in muscle, immunity, and the gut:\u003c\/strong\u003e L-Glutamine is the most abundant free amino acid in plasma and tissues of the human body, accounting for up to 60% of the total free amino acids in skeletal muscle. Although classified as a non-essential amino acid (the body can synthesize it from other precursors), glutamine is considered \"conditionally essential\" in contexts of high metabolic stress, including intense and prolonged physical exercise, illness, surgery, or trauma, where the rate of consumption exceeds the capacity for endogenous synthesis and the body enters a negative glutamine balance. Oral supplementation with L-Glutamine replenishes plasma and muscle reserves, supporting multiple physiological functions that depend on adequate availability of this amino acid.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSupport for muscle recovery and reduction of post-exercise catabolism:\u003c\/strong\u003e During intense physical exercise, plasma glutamine levels decrease significantly, especially in long-duration (more than 90 minutes) or high-intensity sessions. This decline is one of the mechanisms responsible for the transient immunosuppression observed after exhaustive exercise (the so-called \"open window\" of immune vulnerability), as well as for the muscle protein catabolism that occurs in the hours following intense training. Supplementation with L-Glutamine post-workout helps to replenish depleted reserves, supporting muscle recovery, reducing protein catabolism, and contributing to the maintenance of immune function in the post-exercise period.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSupport for intestinal mucosa health and integrity:\u003c\/strong\u003e L-Glutamine is the main energy substrate for enterocytes (intestinal epithelial cells), which depend almost exclusively on glutamine (and not glucose) for their energy. Adequate glutamine availability is essential to maintain the integrity of the tight junctions of the intestinal epithelium, which act as a physical barrier against the passage of pathogens, toxins, and undigested food particles into the bloodstream. In athletes with a high training volume, the oxidative and inflammatory stress associated with intense exercise can compromise the integrity of the intestinal barrier, making L-Glutamine supplementation especially relevant for maintaining gastrointestinal health.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSupport for the immune system: fuel for lymphocytes and macrophages:\u003c\/strong\u003e In addition to enterocytes, immune system cells (especially lymphocytes and macrophages) are large consumers of glutamine, which they use as their main energy source for cell proliferation and for the synthesis of cytokines, antibodies, and other immune mediators. In contexts of intense exercise, illness, or stress, the competition between muscle (which releases glutamine into the plasma) and immune cells (which consume it) can result in a negative glutamine balance and compromised immune function. Supplementation helps maintain the plasma glutamine levels necessary for the normal functioning of the immune system during and after periods of high demand.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eKyowa Quality® Version: pharmaceutical purity with world-renowned Japanese certification:\u003c\/strong\u003e The Kyowa Quality® version of HSN L-Glutamine uses raw material produced by Kyowa Hakko Bio, the Japanese company that pioneered the development of industrial-scale amino acid fermentation technology and is now the global benchmark for amino acid quality and purity. Kyowa Quality® certification guarantees production with pharmaceutical quality standards, verified maximum purity, compliance with Japanese (JP), American (USP), and European (EP) Pharmacopoeias, and the absence of animal-derived ingredients or GMOs. L-Glutamine Kyowa Quality® is presented exclusively in the L-enantiomer (the biologically active form), with maximum bioavailability.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePlant-based fermentation: vegan, free from animal-derived ingredients and GMOs:\u003c\/strong\u003e Both versions of HSN L-Glutamine are produced by microbial fermentation from plant sources, without any involvement of animal-derived ingredients or GMOs, making them suitable for vegan and vegetarian diets. The fermentation and filtration process ensures that the final product has a neutral (not bitter) taste, unlike glutamines produced by acid-based processes, which tend to have unpleasant flavours.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMicronization for instant solubility and mixing versatility:\u003c\/strong\u003e HSN L-Glutamine is micronized with a very small particle size that ensures rapid and homogeneous dispersion in any liquid (water, milk, juices, or shakes), without clumping and without precipitation at the bottom of the container.
