How We Research

Transparency about our methodology builds trust. Here's exactly how NutriState creates supplement research.

Our 6-Step Process

Research & Literature Review

We start with a literature review of relevant peer-reviewed studies, meta-analyses, and clinical trials using PubMed, CrossRef, and Google Scholar. Scope and depth vary by article type.

Source Evaluation

We evaluate sources for quality, methodology, and relevance. Primary sources (clinical studies) are preferred over secondary sources. We assess study design, sample size, and potential bias.

Data Synthesis

We synthesize findings across studies, looking for consensus and disagreement. We highlight mechanistic research (how something works) and applied research (real-world benefits).

Expert Review

Some higher-stakes articles are reviewed by a qualified professional before publication. Not all articles go through this step — reviewer credit appears where applicable.

Fact-Checking & Verification

We fact-check all claims and citations. Claims are verified against original sources, not summarized sources. Ambiguous or contradictory findings are disclosed.

Publication & Updates

Articles are published with full citations. We update articles when new research emerges or errors are discovered. Updates are dated and noted.

Source Hierarchy

We prioritize sources in this order of reliability:

1. Published Meta-analyses & Systematic Reviews
Highest quality: synthesis of multiple high-quality studies by independent researchers
2. Randomized Controlled Trials (RCTs)
Gold standard for clinical evidence; minimizes bias through randomization and blinding
3. Observational Studies & Cohort Studies
Useful epidemiology; less robust than RCTs but can show real-world patterns
4. Mechanistic & Biochemical Research
Explains how supplements work at the cellular level; useful context but not proof of efficacy
5. Expert Opinion & Reviews
Perspective from qualified researchers; useful for interpretation but not independent evidence

What We Do (And Don't Do)

✓ We Do

• Cite primary sources (original studies)
• Disclose affiliate and sponsorship relationships
• Acknowledge research limitations and gaps
• Present conflicting viewpoints fairly
• Update when new research emerges
• Welcome corrections and feedback
• Remove or update outdated information

✗ We Don't

• Make medical diagnoses
• Promise cure-all results
• Recommend without context
• Ignore contradictory evidence
• Promote products based on affiliate ROI
• Use outdated or withdrawn studies
• Rank supplements without disclosure

Content Types

Not every topic requires the same depth. NutriState uses several content types so readers always know what level of coverage to expect.

Cornerstone Article

Longer-form reference guide covering mechanism, dosing research, safety, and practical application. Reviewed where applicable. Evidence level classified.

Featured Guide

Moderately detailed article with good source coverage and practical takeaways focused on a specific topic.

Practical Guide / Quick Guide

Concise and actionable. Focuses on protocol, implementation, or a narrow question. Good for readers who want answers directly.

Reviewed Guide / Comparison

Product evaluation or head-to-head comparison: ingredients vs. clinical benchmarks, label transparency, value analysis. Affiliate status disclosed.

Quality Standards

All NutriState content meets these baseline standards:

Evidence-graded claims — Every factual claim is linked to a primary source. Evidence quality (high/moderate/low) is classified per article.
Depth matched to content type — Cornerstone articles receive the most treatment. Quick guides stay focused on actionable takeaways. Content type is labeled on every article.
FDA/FTC compliant health claims — No unsubstantiated therapeutic claims
Expert review where applicable — Some higher-stakes health and nutrition articles are reviewed by a qualified professional before publication. Reviewer credit appears on those articles.
Full citations — Every claim has a source link where possible
Practical takeaways — Research explained in context: dosage, timing, who benefits, when to expect results

Not Medical Advice

Articles on NutriState are informational only. They do not constitute medical advice. Before starting supplements, consult a healthcare provider, especially if you:

• Take prescription medications
• Have underlying health conditions
• Are pregnant or breastfeeding
• Are scheduled for surgery
