Common questions about evidence sourcing, medical disclaimers, and the 9 CITED specialty sites.
Cited Health is an evidence-based supplement and health information platform. Every health claim is backed by citations to peer-reviewed scientific literature (PubMed-indexed studies, meta-analyses, systematic reviews). Each evidence card includes citation count, study designs (RCT, cohort, case-control), and direct links to PubMed. No 'wellness' or 'natural' claims without sourcing.
No. All Cited Health content is for informational and educational purposes only. Widgets show what research says about ingredients and conditions, but are not a substitute for professional medical advice. Always consult a licensed healthcare provider before starting any supplement — especially if you take medications, are pregnant or nursing, or have a chronic condition. Cited Health does not diagnose or treat.
HairCited (hair growth, loss, supplements), SleepCited (insomnia, melatonin, sleep hygiene), GutCited (microbiome, probiotics, IBS), ImmuneCited (vitamin C/D, zinc, immune support), BrainCited (nootropics, cognitive supplements), WeightCited (metabolism, weight loss), HeartCited (cardiovascular, cholesterol), SkinCited (collagen, retinol, skin barrier). Cited Health is the umbrella hub.
Each ingredient-condition pair has a grade: STRONG (multiple RCTs or meta-analyses with consistent positive findings), MODERATE (some RCTs with mixed results, or strong observational evidence), WEAK (limited or low-quality studies, mechanistic only), INSUFFICIENT (no quality human studies). The widget displays the grade prominently. Browse all ingredients and conditions.
Yes — the interaction widget (data-citedhealth="interactions") shows known supplement-drug interactions documented in DrugBank, NCCIH, and peer-reviewed literature. Severity: MAJOR (contraindicated), MODERATE (use with monitoring), MINOR (clinically insignificant). Always disclose all supplements to your prescribing physician — interactions can be life-threatening (e.g., St. John's Wort with SSRIs).
Citations refresh monthly via the PubMed/NLM API. New systematic reviews and high-quality RCTs added within 30 days of indexing. Old citations preserved (retracted studies flagged with RETRACTED badge rather than deleted). Each evidence card shows 'Last reviewed: <date>'. Full REST API at citedhealth.com/developers/.
