Sources Methodology This page explains how Supplement Explained thinks about source quality, evidence hierarchy, and what should or should not count as support for a supplement claim. It exists so readers can see the sourcing rules behind the content instead of having to guess at them. A clear sources methodology should tell readers which source types are prioritized, which ones are treated more cautiously, and how uncertainty is handled when the evidence does not line up cleanly. Methodology layer Source quality before confidence Trustworthy supplement content usually comes from explaining source quality and evidence limits, not from sounding certain all the time. Evidence review How We Review Evidence See how these source rules are applied once a page is being written. Workflow Research Process See how sourcing fits into the broader editorial workflow. Publishing rules Editorial Policy See what the source methodology is expected to protect. Applications Quality See where label claims and testing language are translated into practical decisions. Why does sources methodology matter for supplement content? Because supplement pages can sound confident while standing on weak support. A visible sources methodology helps readers see whether a site is leaning on real evidence, marketing copy, or isolated claims that only look scientific from a distance. What kinds of sources are prioritized most? Broader institutional sources are usually the starting point for facts, safety, and regulation. After that, better evidence summaries and stronger human studies help clarify what has actually been studied, in whom, and at what dose. Primary studies matter, but a single paper should not get to overrule a wider evidence picture too easily. How do we exclude weak or misleading support? We look at design quality, population fit, dose fit, outcome quality, and whether a source is actually addressing the claim being made. A flashy mechanism, a weak study, or a page built around one exciting number should not be treated like settled proof. How are older studies, forums, and product selection handled? Older studies can still matter, but age alone does not make them strong. Forums are used for reader-intent and anecdotal context, not as proof. Product decisions add another layer because a product label may not match the ingredients, doses, or forms that were actually studied. What should readers look for in a trustworthy sources methodology page? Look for clear source priority, visible limits, honest uncertainty language, and a real explanation of how conflicting evidence gets handled. If the page talks about trust but never explains what counts as good evidence, that is a problem. Key Takeaways Source quality matters as much as writing quality in supplement content. Institutional sources, evidence summaries, and stronger human studies usually carry the most weight. Anecdotes can help explain reader questions but should not replace evidence. A good methodology page explains both what gets included and what gets treated cautiously. Next Questions to Read How We Review Evidence Research Process Editorial Policy Quality Products Source hierarchy Institutional and regulatory sources first. FDA, FTC, NIH ODS, NCCIH, MedlinePlus, and similar sources help anchor broad facts, safety, and regulatory context. Systematic reviews and meta-analyses next. These often help show where the evidence leans overall and where it stays mixed. Stronger human trials after that. Randomized and better-designed human studies matter most when use-case detail, dose, or population fit becomes important. Anecdotes stay in a separate lane. Public forums may help with reader language and recurring complaints, but they do not replace evidence.
