Health Reference Library

About the editor

This library is edited by Henry Bond, founder of Nutri Tailor.

Henry's role on the library is purely editorial, he is not a clinician. The Nutri Tailor Health Reference Library does not give medical or personal health advice. It compiles peer-reviewed evidence and statutory guidance, with sources visible on every entry, so readers can verify what the published research shows.

How entries are written

Every entry follows a fixed structure: a question-shaped title, a 200–300 word summary, then canonical sections covering mechanism, dose, form, timing, safety, special populations, interactions, guideline positions, practical framework, and common misconceptions. The structure is designed so the answer to a specific question is easy to find, and so each claim sits next to the source that supports it.

Source-anchoring is at the sentence level. Every clinical assertion in the library is tied to either a peer-reviewed source (cited with PMID or DOI) or a UK statutory body (NICE, NHS, SACN, BNF, MHRA) or an international authority (WHO, EFSA, NIH Office of Dietary Supplements, Endocrine Society, Cochrane).

The BANT-aligned citation standard

The library applies a five-layer citation hierarchy aligned with the British Association for Nutrition and Lifestyle Medicine (BANT) standard:

  1. BANT-curated databases — Nutrition Evidence Database (NED) and NatMed Pro, where applicable.
  2. Evidence hierarchy — Level 1 (systematic reviews, meta-analyses, Cochrane Reviews), Level 2 (RCTs), Level 3 (prospective cohort studies). Lower-tier evidence (cross-sectional, case-control, narrative reviews) is used cautiously and flagged. Animal-only or in vitro-only studies are not cited as evidence for human clinical claims.
  3. Statutory and authoritative bodies — NICE, NHS, SACN, BNF, MHRA, FSA in the UK; WHO, EFSA, NIH ODS internationally.
  4. Bibliographic indexes — PubMed/MEDLINE, Cochrane Library, EMBASE, CINAHL, Web of Science.
  5. Peer-reviewed journals — BMJ, The Lancet, JAMA, NEJM, AJCN, Nutrients, JCEM, and equivalent indexed journals.

The full standard, including what is explicitly excluded, is at /apps/learn/methodology.

What evidence-based practice means here

The library follows the Complementary and Natural Healthcare Council Code of Conduct definition of evidence-based practice (citing Sackett 2000): research evidence + clinical expertise + patient values, weighted equally. The voice is suggestive, not prescriptive — readers are pointed to the evidence and to qualified professionals; no entry tells anyone what to take.

How entries are reviewed

Editorial sign-off is the gate. No entry goes public without it. Sign-off is supported by two earlier passes:

  1. An AI-assisted review against the underlying source literature on PubMed, NICE, NHS, SACN, BNF, MHRA, and recognised international guideline bodies. The pass verifies that each claim is supported by what the cited paper says, that PMIDs match the recorded titles, that DOIs resolve, and that statutory guidance is current.
  2. A second pass that confirms the synthesis is accurate to its sources, sections appear in canonical order, MHRA and ASA wording rules are met, and any claim without direct source support is removed or flagged.
  3. Editorial sign-off — the entry is not published until I'm satisfied with both passes.

Last-reviewed dates appear on every entry. Sources appear on every entry, linked to PubMed (PMID) or DOI where available. Confidence levels are graded explicitly: strong, moderate, limited.

What changes — and how that's logged

Clinical evidence shifts. When a guideline body changes its position, when new research lands that meaningfully changes what the literature shows, or when an error is found in an existing entry, the entry is updated and the change is recorded in a per-entry change log. Change logs are visible to readers — we publish what changed, when, and why, including corrections.
