Background

PlainVitamins is an independent data-journalism portal that analyzes the NIH Dietary Supplement Label Database (DSLD) to provide plain-language insight into supplement composition, labeling, and the brands and ingredients on the U.S. market. Pages are rendered directly from the source label records by a continuous editorial pipeline, no figure is hand-typed by an editor, and the team is responsible for how the data is sourced, framed, and corrected, maintaining editorial independence by not accepting payment from entities it covers.

Editorial approach

The PlainVitamins Editorial editorial process follows PlainVitamins's Editorial Standards for Data Journalism. Every dataset we cover is traced back to its originating public source, and we publish the provenance of each statistic on the page so readers can verify it independently. We do not accept compensation, sponsorship, or influence from entities we cover.

When we present derived numbers (rankings, ratios, comparisons), the methodology page documents exactly how the figure was computed. If a number cannot be computed consistently across every entity in the dataset, we either disclose the gap or omit the comparison rather than present misleading data.

How content is produced

Raw source figures shown on a data page are reproduced directly from the upstream source agency, and the originating dataset is named and dated on the page. Where a figure is derived (a ranking, ratio, score, or estimate computed from those raw inputs) rather than a raw agency number, it is computed using a documented formula (see the methodology page) and labeled accordingly — "estimated," "modeled," or a named score — never presented as an unmodified source value. The plain-language summaries and explanations that surround those figures are written to help readers interpret the data, while the underlying values are computed directly from the source, not hand-entered.

Source attribution is shown on every page; the methodology underlying any derived figure is documented at the link above. We follow the guidance of Google Search Central's Helpful Content principles — write for readers, document sources, and disclose the editorial process — and welcome any factual flag at the contact link below.
