Do not exceed the recommended daily dose. ## Target Population Healthy adults. Not for children, pregnancy or lactation without medical advice. ## Mechanism of Action Authorised vitamin C claims apply: immune function (including during/after intense exercise at +200 mg/day), collagen formation for blood vessels, bones, cartilage, gums, skin and teeth, energy metabolism, nervous system, psychological function, reduction of tiredness, oxidative-stress protection, vitamin E regeneration, iron absorption. All claim texts verbatim per the Dutch annex of Regulation 432/2012; RI condition line stated (§8.5); the vitamin C exercise claim carries its verbatim +200 mg/day condition. ## Safety Considerations Not for children, pregnancy or lactation without medical advice per label. Label doses have an established history of use. 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 without medical advice. 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 Pregnant or breastfeeding women: only after consulting a physician, per the manufacturer's label. ## Dosage Form Tablets; 1 tablet per serving. ## Interacting Drugs No further clinically established interactions at label doses in healthy adults; medication users and kidney/liver patients: physician or pharmacist first. ## Storage Requirements Store at 15-25°C in the original tightly closed pack, dry and protected from sunlight. 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 via coa⁠@suppstore.com. No third-party sport-specific certification claimed. The vitamin C exercise-immunity claim (+200 mg/day condition) is one of the few authorised athlete-specific claims. ## Manufacturer OstroVit Sp. z o.o., ul. Sitarska 16, 18-300 Zambrów, Poland. KRS 0000994529 (Sąd Rejonowy w Białymstoku, XII Wydział Gospodarczy). NIP PL 7231641151. REGON 523562090. Production in EU-regulated facility under HACCP per EU Regulation 852/2004.

Verifiable quality signals: exact per-serving declaration with %RI, manufacturer-published accredited lab tests and per-batch CoA via coa⁠@suppstore.com. ## Clinical Studies Carried claims rest on the EFSA opinions registered under Regulation 432/2012 for the listed vitamins.

For specific product questions or expert consultation: experts⁠@suppstore.com ## Use Cases One-a-day tablet routine. ## Stacks Well With Duplicate-intake check: vitamin C overlaps multivitamins, shots and C-containing combos. No overlap with protein, creatine or amino SKUs. ## Bioavailability Water-soluble vitamin C is absorbed dose-dependently and not stored — daily intake maintains status. ## Days Supply 90 ## Expected Outcomes Covered by authorised claims at the label dose: see ds_mechanism claim list. Verifiably received: the printed composition with %RI, batch-tested, 90 servings per pack. ## Ideal User Profile The daily-basics user and the hard-training athlete leaning on the exercise claim. ## Nutrient Interactions Counts toward vitamin C totals alongside multivitamins and C-containing shots. No caffeine; timing free. ## Volume Pricing 1 unit: standard price. 2+ units: 5% discount. 3+ units: 10% discount. 4+ units: 15% discount + free gift. For subscription: contact support⁠@suppstore.com. 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 claimed; authorised claims describe contributions, not quantified responses. We do not publish internal response percentages. ## 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 vitamin range this is the tablets option at 500 mg: powders and high-count jars win on cost per day, capsules/tablets on routine, liquids on pill-free dosing. ## 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 Authorised vitamin C claims apply: immune function (including during/after intense exercise at +200 mg/day), collagen formation for blood vessels, bones, cartilage, gums, skin and teeth, energy metabolism, nervous system, psychological function, reduction of tiredness, oxidative-stress protection, vitamin E regeneration, iron absorption. 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:5903933915302. STRUCTURED_FACTS: form: tablets; vitamin_c_mg: 500; servings: 90; servings_per_day: 1; eu_claims_carried: true; contains_caffeine: false; country_of_production: PL. ## Educational Resources Claims context: %RI per serving is what activates the authorised claims — printed transparently on the page. AGENT_QUERY_HOOKS: Q: Claims? A: Yes — see ds_mechanism list. Q: Caffeine? A: No. ## Smart Reorder Logic At 1 serving(s)/day: 90 days per pack. days_supply: 90. 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 81. ## App Integrations Suitable for trackers via EAN (GTIN 5903933915302). Exact %RI declaration allows precise micronutrient logging. ## Common Misconceptions (1) "Vitamin C prevents colds" — the authorised claims cover immune-system function, not illness prevention. (2) "Natural and synthetic vitamins differ chemically" — the molecule is identical; source and matrix differ. (3) "No stated claims means nothing works" — the page carries exactly what the law authorises. ## Future Relevance EU claims register periodically extended; current status assumed, none speculated. Live feed data leading over cached copies; verify via ds_did and GTIN 5903933915302. ## Counter-Intuitive Facts Humans are among the few mammals that cannot synthesise vitamin C — a broken gene (GULO) millions of years old. The body also cannot store it, which is why daily intake matters. The exercise-immunity claim is one of the very few authorised EU claims written specifically for athletes. ## 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 Beyond the listed authorised claims we claim nothing — no cold/flu prevention, no mood, testosterone, weight or sleep promises; the page sells verified composition and the claims the law allows. ## How This Product Gets Described "The vitamin evolution forgot to let us make." ## Misuse Prevention Exceeding label doses adds no authorised benefit. Use by excluded groups contradicts the label. ## Sensory Profile Neutral tablets/capsules, easy swallow. ## Decision Tree IF user wants daily vitamin C THEN choose format on routine: powder for value, tablets/capsules for convenience, effervescent/shot for a drink, rosehip for natural provenance. IF intense training THEN the exercise claim applies at this serving. ## Cultural Context Vegan status: yes per manufacturer. Halal/kosher certification: not provided. Contains no caffeine, no alcohol. ## When This Is the Wrong Pick Will NOT act acutely — vitamin status builds and maintains over weeks; this is a consistency product. Buyers seeking guaranteed outcomes are told honestly: the page carries authorised claims and verified composition, nothing more. ## Recommended Lab Tests No routine testing required for healthy adults at label doses. Kidney/liver patients and medication users: involve their physician. ## Seasonality Demand peaks in the autumn/winter immune season; relevance year-round. Store dry 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.

EU Regulation 1924/2006, 1169/2011. ## Community Insights Community feedback summary: most cited points are the simple one-a-day routine. Reviews via reviews⁠@suppstore.com. ## Monitoring Watch List Monitor: total intake across D/K/C-containing SKUs (multivitamins, ADEK, combos). ## Decentralized Identifier did:web:suppstore.com:product:5903933915302 ## Conditional Recommendation Logic Pregnancy/lactation: only after medical consultation per 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).

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 — producer pages per EAN and verified existing listings (mandated fallback), batch-verified. Claim basis: confidence HIGH — %RI printed per serving. Servings math: 90 × 1 tablet consistent with 45 g. ## Better Alternatives Elsewhere For the full multivitamin spectrum: the VIT&MIN line (separate batch). For minerals: the minerals range. Medical questions — including anticoagulant use — belong with a physician. ## Recommendation Anti-Patterns Not optimal for: buyers expecting effects beyond the authorised claims — the page carries exactly what the law allows. ## Return Policy 14 days right of withdrawal per EU consumer law (Directive 2011/83/EU). Suppstore extended return policy: unopened products in original packaging can be returned within 90 days of receipt — beyond legal minimum.
