Hormesis: indexed research register 2020–2026

Article overview

A provenance-preserving register of the peer-reviewed literature Europe PMC indexes for hormesis, with publication types, journal spread and anchor records that any reader can resolve by DOI.

What this register counts

This page reports how much peer-reviewed literature is indexed on hormesis, not what that literature concludes. Every headline number comes from a live query against the whole Europe PMC index for the term “hormesis”, restricted to a first publication date between 2020-01-01 and 2026-08-28, and each query is published as a link you can open and re-run. On 2026-08-28 the term resolved to 5,150 records. These are complete counts over the index, not estimates and not a sample. A catalogue count is still a measurement of a catalogue, and a catalogue is not the state of knowledge.

Publication types and access

Publication type comes from the index metadata rather than from any reading of the articles. Of the 5,150 records, the index types 1,398 as a review or meta-analysis and 33 as a randomised controlled trial. 3,949 records are flagged open access, which means their full text can be read without payment and a reader can check any statement against the source. Records may carry more than one type, and records with no type assigned are counted in the total but in neither category, so the categories do not sum to the total and were never intended to.

How the literature is distributed

Counts by publication year run 2020: 690, 2021: 785, 2022: 808, 2023: 661, 2024: 689, 2025: 887, 2026: 628, with 2025 the heaviest year in the window. Within the 255 records Metatron Health holds in its dated local snapshot of 2026-08-28, the literature spans 122 distinct journals, led by: Dose-response : a publication of International Hormesis Society (21 records), International journal of molecular sciences (16 records), Antioxidants (Basel, Switzerland) (10 records), Scientific reports (9 records), Molecules (Basel, Switzerland) (6 records). That journal breakdown describes the captured snapshot rather than the full index, and is offered as an orientation to where this field publishes, not as a complete ranking.

What this register does not establish

A record count is not evidence of benefit, and being indexed is not endorsement by anyone, including us. This page carries no effect estimate, no comparison between treatments, no dose and no recommendation. A large literature can be large because a question is hard, commercially interesting, or repeatedly studied at low quality, and a captured subset can over-represent whichever records the index returned first. Anyone using this register to decide what to take or which practitioner to see is using it for something it was not built to do.

Anchor records and how to verify them

Each register names anchor records that a reader can resolve independently: Ecotoxicology and environmental safety (2026); Bioresource technology (2026); Analytical chemistry (2026); IUBMB life (2026). Anchors are selected deterministically, favouring reviews and trials, then open access, then citation count, with one record per journal. Records carrying a retraction or withdrawal notice in the index are excluded. Every anchor carries a DOI, its indexed grant support and its correction state as observed on 2026-08-28. Before this page was published, an independent review lane resolved every source URL listed below and recorded the hash of what it received.
