Sobre SleepCited
Pesquisa de suplementos baseada em evidências em que você pode confiar.
Nossa Missão
Cited Health is an evidence-based supplement research network. We believe every health claim about dietary supplements should be backed by peer-reviewed scientific research — not marketing hype, influencer endorsements, or anecdotal testimonials. That's why every claim on our sites is cited with its source study.
Our mission is to make supplement research accessible and transparent. We systematically search PubMed for clinical trials and observational studies, extract structured data from each paper, and calculate evidence grades that tell you at a glance how strong the science really is.
O Que Nos Diferencia
Unlike supplement review sites that rely on affiliate commissions to drive recommendations, our evidence grades are calculated algorithmically from study data. An ingredient receives an F grade when the evidence warrants it, regardless of whether we earn affiliate revenue from that product. Our grading methodology is transparent and reproducible.
Nosso Compromisso
Cada nota de evidência neste site é calculada a partir de dados de estudos revisados por pares. Parcerias de afiliados nunca influenciam nossas avaliações.

Nossa Equipe
Cited Health Research Team
Evidence Review — PubMed systematic search methodology
Our research team conducts systematic searches of PubMed and PubMed Central to identify relevant clinical trials, meta-analyses, and observational studies for every ingredient-condition pair.
AI-Assisted Extraction
PICO Data Extraction — Claude AI with human oversight
Study data (population, intervention, comparison, outcome) is extracted using AI assistance, then validated against source publications. Every extraction includes a confidence score and risk-of-bias assessment.
Algorithmic Grading Engine
Evidence Grading — Transparent, reproducible scoring system
Evidence grades (A through F) are calculated algorithmically based on study type quality, result consistency, total sample size, and number of studies. The grading algorithm is deterministic and reproducible.
Fontes de Dados
