Editorial policy

Rules that make the dataset auditable

Coverage and calculations follow published rules. Commercial relationships do not determine inclusion, order, or conclusions.

Census, not curation

The project starts from the supplied on-market label census and documents how records move through the coverage funnel. Inclusion records a filed label, without endorsing the product.

Provenance on every number

Table rows carry an NIH DSLD label ID, price observation date, retailer, and verification status. Derived figures state their population and assumptions.

Corrections welcome

Email hello@elementaldose.com. We will acknowledge correction reports within five business days and maintain a public correction log with the affected release.

No paid placement

Commissions, if any, never influence rankings or figures.

Form boundaries

Ordering is permitted only within a magnesium form. Across forms, ElementalDose reports a neutral matrix and does not name a winner.

AI crawler access

The site is launched and AI crawlers are welcome under the published robots.txt rules.

Page-use events

We count page views and selected button actions to see whether pages help people. Events contain the page type and identifier, template, data release and time; this own counter uses no cookies, browser or session identifier, IP address or personal data. Production pages also load Google Analytics through Google Tag Manager, which sets first-party cookies; no advertising cookies are used in the UK, EEA or Switzerland (see About).
