# suppdoc.io

> suppdoc.io is an evidence-graded supplement intelligence platform. It helps people decide what to take and why, personalised recommendations, an interaction checker, bloodwork analysis, and daily tracking, grounded in published research. We do not sell our own supplements, so recommendations are not biased toward a house brand. Every claim links to the evidence and is being moved under named clinician review.

## What suppdoc does
- Builds a personalised supplement stack from a quiz, plain-English goals, or your labs.
- Audits an existing stack for interactions, redundancies, gaps, and timing.
- Reads a blood test (PDF or photo) and matches biomarkers to evidence-led supplements.
- Tracks adherence and wellness over time with a daily check-in.
- Grades every ingredient's evidence tier (very strong, strong, moderate) and cites real studies.
