Review Guidelines – How We Fact Checked

At healthsupplementsexpert.com, we’re committed to providing accurate, science-based information about health supplements. Our readers rely on us to cut through marketing hype and deliver honest, well-researched evaluations. This page explains our rigorous review and fact-checking methodology.

Our Review Process

1. Initial Research & Selection

How we choose supplements to review:

  • Trending and popular products in the market
  • Reader requests and questions
  • Emerging supplement categories with scientific interest
  • Products with significant health claims that warrant investigation

What we don’t review:

  • Products with potentially dangerous ingredients
  • Supplements making illegal disease-treatment claims
  • Products from companies with a history of FDA warning letters or legal issues
  • Supplements with proprietary blends that don’t disclose ingredient amounts

2. Data Collection & Analysis

For each supplement we review, we collect comprehensive data from multiple sources:

Product Information:

  • Complete ingredient list and dosages
  • Manufacturer claims and marketing material
  • Pricing across multiple retailers
  • Manufacturing practices and certifications
  • Company history and reputation

Scientific Research:

  • Peer-reviewed studies on individual ingredients
  • Clinical trials on the specific formula (when available)
  • Meta-analyses and systematic reviews
  • Research from reputable medical journals
  • Position statements from relevant health organizations

Consumer Experience:

  • Verified customer reviews across multiple platforms
  • Social media discussions and feedback
  • Consumer complaint databases
  • Expert opinions from healthcare professionals

3. Evidence Evaluation

We assess the quality of scientific evidence using a tiered approach:

Strength of Evidence Scale:

  • Strong Evidence: Multiple large, well-designed human clinical trials with consistent results
  • Moderate Evidence: Small or limited human trials with generally positive results
  • Preliminary Evidence: Animal studies, in vitro research, or very limited human studies
  • Theoretical Benefit: Based on mechanism of action, but lacking direct studies
  • Insufficient Evidence: Conflicting research or too limited to draw conclusions
  • Evidence Against: Research suggesting ineffectiveness or safety concerns

We consider factors such as:

  • Study design (randomized controlled trials given highest weight)
  • Sample size and study duration
  • Statistical significance of results
  • Whether studies were conducted independently or funded by manufacturers
  • Consistency of findings across multiple studies
  • Whether results have been replicated by different research teams

4. Content Creation

Our content goes through a structured development process:

Initial Draft:

  • Written by subject matter experts with backgrounds in nutrition, pharmacology, or relevant health sciences
  • Structured to address key reader questions about efficacy, safety, and value
  • Includes comprehensive analysis of ingredients, dosages, and formulation

Primary Fact-Check:

  • All scientific claims verified against original research sources
  • Manufacturer claims compared against available evidence
  • Dosages evaluated against clinical research
  • Price analysis and value assessment

Editorial Review:

  • Content edited for clarity, accuracy, and completeness
  • Ensuring balanced coverage of both benefits and limitations
  • Application of consistent rating criteria
  • Implementation of our evidence-based approach

5. Expert Review

Before publication, content undergoes expert review:

  • Scientific Reviewer: Reviews all scientific claims and evidence assessments
  • Medical Reviewer (when applicable): Reviews content discussing specific health conditions
  • Regulatory Compliance Check: Ensures content complies with FTC guidelines and doesn’t make disease claims

6. Regular Updates

Our commitment to accuracy doesn’t end at publication:

  • Reviews are updated when significant new research emerges
  • Product reformulations trigger complete reassessments
  • Reader feedback and questions may prompt additional research
  • Annual comprehensive review of all content

Fact-Checking Standards

Our fact-checking process follows these core principles:

Primary Sources

We prioritize information from:

  • Peer-reviewed scientific journals
  • Official government health agencies (NIH, FDA, etc.)
  • Major medical organizations and associations
  • Direct product information from manufacturers

Verification Process

Each factual claim in our content must be:

  • Verified by at least two independent sources when possible

  • Checked against the most recent available data
  • Qualified appropriately when evidence is limited

Citation Standards

We follow these citation practices:

  • Direct links to scientific studies cited
  • Proper attribution for expert opinions
  • Clear differentiation between scientific consensus and emerging research
  • Appropriate context for research findings

Handling Conflicting Information

When research findings conflict, we:

  • Present multiple perspectives fairly
  • Weigh evidence based on study quality and relevance
  • Disclose limitations and contradictions
  • Avoid cherry-picking only favorable studies

Transparency in Affiliate Relationships

Our commitment to factual accuracy exists alongside our affiliate business model:

  • Editorial decisions and ratings are made independently from affiliate considerations
  • We recommend products based on merit regardless of affiliate relationships
