Sources and verification
We prefer current primary sources, including official product labels, manufacturer records, laboratory reports, regulators, trial registrations, and published research. Each product fact is tied to the exact market, variant, serving, and checked date when those details affect the comparison.
Product comparisons and rankings
Comparison criteria are defined before the final order is chosen. The same fields are applied to every product in the stated comparison set. Missing information is not treated as proof of poor quality, and a marketing claim is not treated as an independent test result.
Rankings can change when a formula, price, public test report, availability, or comparison set changes. The page identifies its checked date so readers can see which version of the market was assessed.
Health and evidence claims
HealthPlugged does not present supplements as treatments for disease or turn animal, cell, or mechanistic findings into established outcomes for people. Human research is described with its population, dose, duration, outcomes, and important limitations.
Commercial relationships
A commercial client may be included when the product fits the published scope and can be assessed on the same criteria as every other candidate. The relationship is disclosed on the affected page. Commercial status does not guarantee inclusion, rank, or a positive conclusion.
Updates and corrections
Time-sensitive details are rechecked when an article is materially updated. We do not change a publication date solely to make a page appear newer. Confirmed factual errors are corrected under our corrections policy.
