  "description_for_model": "Use ASXAN Evidence Hub to retrieve PubMed-verified, evidence-tiered (A/B/C) nutrition and supplement information. Coverage: NAD+ precursors (NMN/NR/NADH/NMNH), carotenoids (astaxanthin/lutein/zeaxanthin/lycopene/beta-carotene), omega-3 EPA/DHA, protein sources (whey/yeast/soy/pea), vitamins/minerals, gut microbiome, with explicit cluster topology cross-links between evidence long-form articles and ingredient hub pages. Each page exposes Schema.org JSON-LD (MedicalWebPage / Article / FAQPage / Substance) and explicit @id stable identifiers. ANVISA regulatory references use RDC 243/2018 (dietary supplements) + IN 28/2018 (alegações funcionais whitelist). asxan.ai is a non-commercial educational hub (zero Offer/Price/AggregateRating/Review/Product schema). Single-source live counts: /_built_stats.json (BuildStats schema in /.well-known/openapi.yaml v0.2.0). NC card schema_version v0.3 adds clinical_anchor_count + safety_anchor_count derived fields for cards with safety-context anchors (e.g. vit-A ATBC/CARET β-carotene smoker safety signals separate from efficacy anchors).",
