Evidence Report — year over year

Each annual edition gets a stable permalink and a pinned dataset version. New years are added; old years are never repointed to the latest data.

Comparison state

2026 baseline established

2026 is the first permanent baseline. When the 2027 edition is added, this page becomes the year-over-year comparison index without changing the 2026 URL.

Archive rule: an annual route may render calculated report metrics only while the active dataset version matches the version pinned to that edition. If it does not match, the archive fails closed instead of substituting newer data.

Learning context

How this concept connects to supplement decisions

Compare annual State of Supplement Evidence editions and track how the underlying dataset changes over time. Learning pages explain the reasoning layer behind the herb and compound library. They are designed to make mechanisms, evidence quality, safety tradeoffs, and product claims easier to interpret.

Use Evidence Report — year over year to build better questions before choosing a supplement: what outcome is being targeted, what mechanism is claimed, what human evidence exists, what dose was studied, and what risks could change the answer for a specific person?

Mechanistic plausibility is useful, but it should be weighed against trial design, safety history, product quality, and the possibility that a simpler intervention may be more appropriate.
