About

Supplement Guide

Features
Read full description

A practical reference for supplements, built around the questions that actually come up in practice: what does the evidence support, what does it interact with, and how much does the dose matter? Search by condition, symptom or supplement name across 27 categories — cognition, cardiovascular, autoimmune, leaky gut, osteoporosis, blood thinning and more — or browse the catalog of 140 entries. What each entry tells you • Evidence strength labeled honestly as Strong, Moderate or Emerging — with emerging entries described as supportive rather than therapeutic • Dose ranges, including when a compound only matters at doses well above culinary or everyday amounts • Major prescription-interaction warnings, flagged only where the interaction is genuinely major • Immune-direction notes for compounds that push TH1 or TH2 activity, so they can be considered in context • Timing and spacing guidance where absorption depends on it Built for reference, not prescription • Filter any category to show only entries carrying major prescription interactions — useful when reviewing a patient's full regimen • Bookmark entries to revisit and star favorites for quick access • View the whole catalog strongest-evidence first — every entry shown under its best-supported use • Works entirely offline — no account, no sign-in A private log of what you take and how you feel • Record each supplement you start, with its start date and your dose • Rate the symptoms you choose to watch, 1 to 5, in a ten-second daily check-in • See it all on a month calendar — a personal record to bring to your clinician Your data stays on your device This app collects nothing. Your log is stored only on your iPhone — there is no account, no analytics, and no data ever sent to us. Important This app is an educational reference only. It does not diagnose, treat, cure or prevent any disease, and it is not a substitute for individualized medical advice. Supplements can interact with prescription medications and with each other. Always consult a qualified healthcare provider before starting, stopping or combining supplements — particularly if you take anticoagulants, are pregnant or nursing, or have a scheduled surgery.
