Quick Start

Introduction

SupplementDEX is an evidence-based dietary supplement and condition handbook for doctors, researchers, and informed patients.

Browse by ingredient or explore conditions — with study-backed summaries you can trust.

Look up individual ingredients — mechanisms, dosing, evidence, and safety.

Find which supplements are studied for a given health condition.

Understand purchase guidance, Effect / Evidence / Trust, and Simple vs Practitioner summaries.

How Effect Size, Evidence, and Trust combine into a single 1–5 score.

Clinical use

SupplementDEX supports clinical decision-making — it does not replace professional judgment or individualized patient care.

Start from a question — e.g. “What can help with PCOS?” or “Is creatine worth it?”
Open the matching section — Conditions for diagnosis-led queries, Supplements for ingredient-led ones.
Read the ratings — purchase guidance plus Effect Size / Evidence / Trust (and DEX score). Open Evidence Review in Simple or Practitioner language.
Check dosing & safety — studied protocols, who it’s for, and key caveats before acting on anything.

Overview & dosage — what it is and studied protocols
Effect graph — scatter of conditions by study volume vs rating
Effect heatmap — sortable grades across conditions (rating, DEX score, and more); click a row to jump to that evidence review
Charts — studies per condition and studies per year
SupplementDEX Database — one block per condition (A–Z) with purchase guidance, Effect / Evidence / Trust, Simple ↔ Practitioner Evidence Review, and expandable studies
Benefit vs risk — practical upsides and downsides
Safety, FAQ & references — caveats and the source trail

Relevant supplements — a table of ingredients studied for that condition (same Rating / Effect Size / DEX Score columns as the Effect heatmap). Click a row to jump to that supplement’s block on the page.
Studies — one section per supplement: purchase guidance, Simple ↔ Practitioner Evidence Review, and a collapsed study list you can open when you need the papers
Evidence visualised — purchase-guidance and effect-size distributions, plus study counts per supplement (transparency trail)
