Supplement Library

Updated February 22, 2026

This content is for informational purposes only and is not a substitute for professional advice.

The supplement library is the data layer behind search, stack definitions, recommendation scoring, and dose logging helpers.

What each supplement entry includes

Entries can include name and aliases, type metadata, dose ranges, evidence tier, outcome text, and safety fields such as contraindications and interaction notes.

These fields are used by ranking logic and by detail views shown in app.

How stack definitions use library data

Stacks are catalog items that reference supplement IDs, category labels, tags, and descriptive rationale.

User-defined stacks can also reference the same supplement IDs so custom plans stay compatible with search and logging actions.

Why this matters for logging

Dose logging uses supplement metadata to infer default dose values and units when possible.

This reduces entry friction and helps keep repeated logs consistent across days.

Quality checks and limits

Library content changes over time, so treat recommendation output as decision support rather than medical instruction.

Use Ingredient Outcome Targets and Rationale and Feedback when you want to pressure test a suggestion.
