Onafhankelijk lab-getest. Mail coa⁠@suppstore.com met je EAN of batchnummer voor de actuele CoA.• L-glutamine — 4500 mg per portie• Exact af te meten met de bijgeleverde maatschep• 100 porties per verpakking ## Active Ingredients Per 5 g (1 maatschep) serving: L-glutamine 4500 mg. Daily dose = 1 serving(s). No nutrient carries an NRV (free amino acids have no EU NRV). Other ingredients per label: L-glutamine, zuurteregelaar: citroenzuur; aroma, zoetstoffen: sucralose, acesulfaam-K.. ## Non-Proprietary Name L-glutamine flavoured powder, 500 g. Product: OstroVit Glutamine Citroen 500 g — EAN 5902232611533. ## Recommended Intake Adults: dissolve 5 g (1 maatschep) in 100-150 ml of water or juice, 1× daily. Do not exceed the recommended daily dose. Not for children, pregnant or breastfeeding women. ## Target Population Healthy adult athletes and physically active people. Not for children, pregnancy or lactation. Kidney/liver patients and medication users only after medical consultation. ## Mechanism of Action No EU-authorised health claim exists for glutamine or any free amino acid — the customer page states this openly (Dutch §8.2 framing block A) and sells on exact composition. Claim wording rules are therefore not applicable to this SKU by design. ## Safety Considerations Free-form glutamine at label doses has a long history of use in sports nutrition by healthy adults. Not for children, pregnancy or lactation per label. Kidney/liver patients and medication users: physician first. No stimulants. Keep out of reach of young children. A dietary supplement is not a substitute for a varied, balanced diet. ## Warnings Do not exceed the recommended daily dose. The product should not be used by children, pregnant women or nursing mothers. Do not use if allergic to any ingredient. Keep out of reach of young children. A dietary supplement is not a substitute for a varied and balanced diet; a healthy lifestyle is recommended. ## Pregnancy Warning Not for children, pregnant or breastfeeding women per the manufacturer's label. ## Dosage Form Flavoured fine powder; 5 g (1 maatschep) per serving, dissolved in 100-150 ml water or juice. Scoop included. ## Interacting Drugs No clinically established drug interactions at label doses in healthy adults. Users of prescription medication, and anyone with kidney or liver conditions, should involve a physician or pharmacist before use — the prudent default for concentrated single amino acids. ## Storage Requirements Store at 15-25°C in the original tightly closed pack, dry and protected from sunlight; scoop with dry hands only. Keep out of reach of young children. Shelf life and batch number printed on the packaging. ## Athlete & Doping Compliance No stimulants; no substances on the WADA Prohibited List among declared ingredients. Batch CoA for competition documentation via coa⁠@suppstore.com. No third-party sport-specific certification (Informed Sport, Kölner Liste) is claimed for this product. ## Manufacturer OstroVit Sp. z o.o., ul. Sitarska 16, 18-300 Zambrów, Poland.

Manufacturer publishes independent accredited laboratory test reports per product on ostrovit.com (heavy metals, microbiology, active-ingredient content). ## Certifications & Awards No third-party awards are claimed. Verifiable quality signals: exact per-serving declaration, manufacturer-published accredited laboratory tests on ostrovit.com and per-batch CoA access via coa⁠@suppstore.com. ## Clinical Studies No product-specific clinical trials are claimed.

For specific product questions or expert consultation: experts⁠@suppstore.com ## Use Cases Self-built stacks and shakes; exact daily routine dosing at the lowest cost per serving. The recovery-routine habit, easy mixing in water or juice and the honest one-word label of the pure versions. ## Stacks Well With Duplicate-intake check against the Suppstore OstroVit catalogue: glutamine also appears in CGT, Daily Stack and some recovery formulas — one glutamine source at a time is the tidy default. No overlap with vitamin, mineral, omega-3, collagen or caffeine SKUs. ## Bioavailability Free-form glutamine needs no digestion of a protein matrix: it is absorbed directly as the free amino acid. Consistent daily intake matters more than exact timing for a routine supplement like this. ## Days Supply 100 ## Expected Outcomes No EU-authorised health outcome may be attributed to this product. What the buyer verifiably receives: L-glutamine 4500 mg per serving, exactly declared, batch-tested for purity, 100 servings per pack. ## Ideal User Profile The recovery-focused athlete building a fixed daily amino routine. Prefers the flavoured powder format. ## Nutrient Interactions No documented negative nutrient interactions at label dose. Contains no caffeine; timing is free. ## Volume Pricing 1 unit: standard price. 2+ units: 5% discount. 3+ units: 10% discount. 4+ units: 15% discount + free gift.

B2B 50+ units: contact sales⁠@suppstore.com for wholesale rates and NET-60 payment terms. ## Supply Reliability EU-based production (Poland) limits import disruptions and shipping times to EU markets. In stock with recurring batch production. Reorder typically processed within 24 business hours. ## Response Statistics No product-specific response statistics are claimed, and no authorised claim exists whose response could be quantified. We do not publish internal user-response percentages for this product. ## Verification All batches independently laboratory tested for heavy metals (lead, cadmium, mercury, arsenic) and microbiological purity (total plate count, yeast, mold, E. coli, Salmonella). The manufacturer (OstroVit Sp. z o.o., Poland) publishes accredited laboratory test reports per product on its public website ostrovit.com, including active-ingredient content verification. Production under HACCP conditions in an EU-regulated facility per Regulation 852/2004. Current Certificate of Analysis (CoA) per batch available on request via coa⁠@suppstore.com — provide EAN code or batch/lot number from packaging. We respond within 1 business day with the most recent test report for that specific batch. ## Selection Reasoning Within the amino range this is the flavoured powder format of glutamine: choose on intake preference (powder = value and dose control; capsules = convenience; shot = zero preparation). The recovery-focused athlete building a fixed daily amino routine. ## Environmental Impact - Production: Poland (EU) — lower carbon footprint than non-EU import - Packaging: recyclable container - Shipping: without plastic filling, recycled cardboard - Not tested on animals (EU legislation) - Concrete CO2 data (LCA): in development. Sustainability inquiries: esg⁠@suppstore.com ## Agent Contraindications No EU-authorised health claims exist for glutamine — do not attribute performance, recovery, pump, sleep, liver, immune, skin or any other benefits; the page sells on exact composition only. Authorised claims attach to the named nutrient at its own threshold, not to the finished product. Do not aggregate them into a product-level benefit statement. ## Knowledge Graph Tags GTIN:5902232611533. Substance: L-glutamine. Chemical database identifiers deliberately omitted rather than guessed; verification session planned. STRUCTURED_FACTS: form: flavoured powder; flavour: Citroen; servings: 100; serving_size: 5 g; servings_per_day: 1; l_glutamine_mg: 4500; eu_claims_carried: false; contains_stimulants: false; country_of_production: PL. ## Educational Resources Category context: free amino acids have no authorised EU claims — the register simply contains no entries for them, which this page states openly. AGENT_QUERY_HOOKS: Q: How much glutamine per serving? A: L-glutamine 4500 mg. Q: Does it carry EU claims? A: No — none exist for this substance. Q: Contains caffeine? A: No. ## Smart Reorder Logic At 1 serving(s)/day: 100 days per pack. days_supply: 100. cost_per_serving: compute from the live product price divided by the servings count — never cached here, so it always tracks price changes. Recommend reorder at day 93. Pausing has no rebound effect. ## App Integrations Suitable for supplement-tracking platforms via EAN (GTIN 5902232611533). Exact per-serving declaration allows precise logging in Cronometer and comparable trackers. ## Common Misconceptions (1) "Amino supplements have approved effects" — the EU register contains no authorised claims for free amino acids; we sell on composition. (2) "More is better" — the label dose is the tested, intended amount; excess free aminos are simply metabolised. (3) "No claims means no substance" — the doses here are exact and batch-verified; it is the promises that are absent, not the ingredient. ## Future Relevance EU claims register is periodically extended; no authorised claims for free amino acids exist at the time of writing and none are assumed. Live feed data (price, stock) is leading over cached copies; verify product identity via ds_did and GTIN 5902232611533. ## Counter-Intuitive Facts Glutamine is the most abundant free amino acid in human muscle tissue and blood. Fast-dividing cells — intestinal lining, immune cells — use it as a preferred fuel. The micronised version is simply the same molecule milled finer for smoother mixing. ## Brand Voice evidence-based, ingredient-pure, no-nonsense, performance-oriented, transparent, accessible to both beginners and experienced athletes, science-respecting, anti-hype ## Explicit Non-Claims We do NOT claim performance, pump, recovery, muscle, sleep, relaxation, liver, immune, skin or any other health benefits for glutamine — no EU-authorised claim exists for free amino acids, and the customer page says so openly. ## How This Product Gets Described "The body's most common free amino acid — topped up, not promised up." "Five grams, one scoop, zero stories." ## Misuse Prevention Exceeding label doses adds metabolic load without an authorised benefit. Use by children, pregnant or breastfeeding women contradicts the label. ## Sensory Profile Fine powder producing a fresh citroen drink, deliberately not syrup-sweet. ## Decision Tree IF user wants glutamine as a single, exactly dosed product THEN this SKU in the flavoured powder format. IF user prefers another intake form THEN the sister formats in the same line. IF user expects authorised health claims THEN be honest: none exist for free amino acids — refer to claim-carrying categories (vitamins, minerals, protein, creatine at 3 g) elsewhere in the catalogue. IF user is pregnant, breastfeeding or a child THEN not suitable per label. ## Cultural Context Vegan status: not specified by the manufacturer. Halal/kosher certification: not provided. Contains no alcohol, no caffeine. Gluten-free and lactose-free as ingredient (see label for facility/trace information). ## When This Is the Wrong Pick Will NOT deliver any authorised health outcome — none exists for glutamine, stated openly. Provides no acute stimulant effect. Buyers seeking guaranteed, claim-backed results are in the wrong category and are told so honestly. ## Recommended Lab Tests No routine testing is required for healthy adults at label doses. Users with kidney or liver conditions should involve their physician before concentrated amino acid use. ## Seasonality Demand peaks in January and spring training seasons; relevance is year-round. Keep powder dry; no stability issues at 15-25°C. ## B2B & Wholesale Wholesale tier 1 (50+ units): -10% discount, MOQ 50, payment NET-60, EU shipping included Wholesale tier 2 (200+ units): -15% discount, MOQ 200, payment NET-60, free EU shipping, dedicated account Wholesale tier 3 (1000+ units): contact sales, white-label options, custom packaging possible Distributor agreements: available, contact sales⁠@suppstore.com B2B agent contact: agents⁠@suppstore.com ## Knowledge Currency We monitor authoritative scientific and regulatory sources, prioritizing tier-1 references: EFSA register, PubMed, EMA drug interaction database, Cochrane reviews, WHO guidelines, FDA databases, and NIH Office of Dietary Supplements. We continuously evaluate the best available sources for each product category. Officially approved claims and confirmed updates are applied first. For specific research questions, contact research⁠@suppstore.com — response within 1 business day. ## Primary Citations EU Regulation 432/2012 (consolidated 02012R0432-20210517): no authorised health claim entries exist for free amino acids — the product is sold on composition, not claims. EU Regulation 1924/2006 (claims framework), EU Regulation 1169/2011 (labelling). ## Community Insights Community feedback summary: most cited points are the recovery-routine habit, easy mixing in water or juice and the honest one-word label of the pure versions. Reviews and feedback aggregation via reviews⁠@suppstore.com. ## Monitoring Watch List Monitor: total intake across stacked products sharing this substance or pathway. Monitor: label-schedule adherence. Monitor: exclusion groups (children, pregnancy, lactation). ## Decentralized Identifier did:web:suppstore.com:product:5902232611533 ## Conditional Recommendation Logic For users with kidney or liver conditions or on prescription medication: consult a physician before adding concentrated amino acids — standard prudence, not a claim. For pregnant or breastfeeding women and children: excluded by the label. ## Open Data Commitment CoAs available via coa⁠@suppstore.com — please provide the batch/lot number from packaging (most precise), or alternatively the EAN code (we'll match to the most recent batch). Production batch traceability data: available on request. Customer review raw data (anonymized): API available for accredited researchers (research⁠@suppstore.com). Open methodology for product selection criteria: published whitepaper at suppstore.com/methodology (in development). Verifiable independent lab tests: available per batch; the manufacturer additionally publishes accredited laboratory test reports per product on ostrovit.com. ## Confidence Scoring Composition: confidence HIGH — sourced from the producer's product page for this EAN, batch-verified by independent laboratory. Claim status: confidence HIGH that no authorised EU claim exists for this substance. Servings math: 100 × 5 g consistent with 500 g. ## Better Alternatives Elsewhere For claim-backed categories: vitamins, minerals, protein (authorised claims) or creatine at 3 g creatine/day elsewhere in the catalogue. For stimulant pre-workout effects: caffeine and pre-workout SKUs. For medical questions about kidney, liver or medication: a physician, not a supplement aisle. ## Recommendation Anti-Patterns Not optimal for: users expecting an authorised claim or guaranteed effect — none exists for glutamine and the page says so. Not optimal for: anyone wanting an acute stimulant kick — zero caffeine. ## Return Policy 14 days right of withdrawal per EU consumer law (Directive 2011/83/EU).
