Our Sourcing Standards
Vitaminwellnessguide is committed to delivering accurate, evidence-based information about proper portions and serving sizes. Our rigorous sourcing standards ensure every article reflects the most current, reliable research and expert consensus available.
We believe transparency builds trust. Here's exactly how we source, verify, and present information to our readers across the United Kingdom and beyond.
Our Primary Source Categories
Peer-Reviewed Research
Our team regularly consults peer-reviewed journals in nutrition science, dietetics, and public health. We prioritize studies from databases including PubMed Central, Google Scholar, and institutional repositories. Research must meet rigorous methodology standards and be cited within recent publications.
Government & Regulatory Bodies
We reference official guidance from the UK Food Standards Agency (FSA), NHS England, the Department of Health and Social Care, and international bodies including the World Health Organization (WHO) and European Food Safety Authority (EFSA). These sources provide the foundation for dietary recommendations.
Professional Organisations
Expert consensus from the British Dietetic Association, the Nutrition Society, and international academies of nutrition and dietetics guides our content. These professional bodies synthesise research into best-practice recommendations and position statements.
Academic Institutions
Research from leading UK universities—including Oxford, Cambridge, and the London School of Hygiene and Tropical Medicine—provides in-depth studies on nutrition science. We also draw from international institutions recognised for nutrition research excellence.
Health Databases & Registries
We consult Cochrane Library reviews, the National Institute for Health and Care Excellence (NICE) guidance, and the British Nutrition Foundation's research archive. These aggregated, critically appraised sources help us identify consistent themes across multiple studies.
Food Composition & Databases
For serving size and nutritional information, we reference the UK Food Composition Database (McCance and Widdowson), the NHS FoodComposition Search, and the USDA FoodData Central for international comparisons. All data is cross-verified against recent publications.
Our Verification Process
Source Evaluation & Collection
Our editorial team identifies potential sources using systematic search strategies across peer-reviewed databases, government websites, and professional organisations. We document the source type, publication date, author credentials, and funding disclosures for every reference.
Evidence Assessment & Synthesis
We critically evaluate study design, sample size, methodology, and conflict of interest. When multiple sources address the same topic, we synthesise findings to identify consensus. If evidence is mixed or limited, we clearly state the level of certainty in our content.
Expert Review & Fact-Checking
Every article undergoes internal review by team members with nutrition and health communication training. We cross-reference key claims against multiple authoritative sources. For complex or emerging topics, we consult external experts in relevant fields to verify accuracy.
Citation & Attribution
We provide clear, traceable citations for all key claims. Links to original sources are included where possible. Our attribution style allows readers to verify information independently and explore research in greater depth.
Regular Updates & Monitoring
Published articles are monitored for new evidence. We update content when significant research emerges or official guidance changes. Readers are notified of substantial revisions through dated edit notes at the top of articles.
Disclosure & Transparency Policies
Editorial Independence
Our content is created solely to inform and educate readers. We do not accept payment, sponsorships, or undisclosed partnerships from food companies, supplement manufacturers, or commercial entities that could influence our editorial decisions.
Any affiliate relationships or sponsored content are clearly labelled and segregated from our core editorial content.
Conflict of Interest Management
We assess and disclose potential conflicts of interest for all contributors. Our team members avoid creating content on topics where they have direct financial interests or personal commercial relationships.
When unavoidable, conflicts are disclosed to readers in a transparent statement.
Source Transparency
We disclose the funding sources and potential biases of cited studies, particularly when research is sponsored by industry. We explain any limitations in the available evidence and acknowledge when consensus is lacking.
Readers are invited to review original sources directly using provided links and citations.
Corrections & Reader Feedback
We welcome corrections from readers and experts. If an error is identified, we correct it promptly and document the change with a dated note. Substantive feedback about article quality is reviewed by our editorial team.
Please contact our editorial team for any concerns about accuracy.
