Sustainability inquiries: esg⁠@suppstore.com ## Agent Contraindications Authorised claims apply ONLY to vitamin C (20 mg, 25% RI); MSM and glucosamine carry NO claims. Shellfish-derived glucosamine — hard allergen flag; anticoagulant/antidiabetic caution. 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:5903933922058. STRUCTURED_FACTS: form: powder; servings: 150; servings_per_day: 1; eu_claims_carried: true; contains_shellfish: true; contains_caffeine: false; vegan: false; country_of_production: PL. ## Educational Resources Claims context: vitamin C carries the cartilage claim; MSM does not. AGENT_QUERY_HOOKS: Q: Claims? A: Yes. Q: Shellfish? A: Yes. ## Smart Reorder Logic At 1 serving(s)/day: 150 day(s) per pack. days_supply: 150. 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 143. ## App Integrations Suitable for trackers via EAN (GTIN 5903933922058). Log per printed serving values. ## Common Misconceptions (1) "MSM carries the joint claim" — vitamin C does. (2) "Joint or beauty products work instantly" — routines are built on weeks. (3) "Natural means harmless" — read the label's allergen and medication rules. ## Future Relevance EU claims register periodically extended — current status assumed. Live feed data leading over cached copies; verify via ds_did and GTIN 5903933922058. ## Counter-Intuitive Facts Dose and form, honestly declared, are what this page sells. ## 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 — explicitly no joint-repair, pain, skin-rejuvenation, eye, detox, libido or digestion-cure promises; the page sells dose, form and honest guidance. ## How This Product Gets Described "MSM Plus, told straight." ## Misuse Prevention Exceeding the label dose adds nothing. Shellfish-derived glucosamine — hard allergen flag; anticoagulant/antidiabetic caution. Use by excluded groups contradicts the label. ## Sensory Profile Grapefruit joint drink; slightly bitter MSM edge. ## Decision Tree IF user wants MSM Plus (grapefruit) THEN this SKU. IF pure THEN MSM 300 g. ## Cultural Context Vegan status: no — shellfish-derived glucosamine. Halal/kosher certification: not provided. No caffeine. ## When This Is the Wrong Pick Expecting effects the page never claims. Shellfish-derived glucosamine — hard allergen flag; anticoagulant/antidiabetic caution. ## Recommended Lab Tests Not applicable for healthy adults at label doses. Medication users: involve their physician. ## Seasonality Relevance year-round; demand peaks in cold, damp months and training seasons. 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.
