NutriStack is a free iPhone app for everything you take: a daily checklist with dose reminders, a label scanner, and a check of how your supplements and prescription medicines combine, with the published source behind every record.

Note 1 · Coverage The app includes a structured supplement catalog with attached literature and authority links where available. Catalog inclusion is not a finding that a substance is effective, safe, or publication-reviewed. How the catalog is made →

Note 2 · Drug list Medication records are included to help organize safety checks. Their presence does not replace an official label, pharmacist review, or prescriber guidance.

Note 3 · Pairs Pair records can contain a stored effect, mechanism, recommendation, and source links. A source attached to either ingredient does not establish that the exact pair has been clinically tested. The checker is exploratory and is not a clinical decision tool.

Note 4 · Labels The scanner looks products up in a bundled catalog of 31,000+ labels drawn from the NIH Dietary Supplement Label Database, then an online catalog. See what those labels say in our label audit.

Reader questions

Questions, answered.

Common questions about the database, the app, and how to use them together. Email support@nutristackapp.com if yours is missing.

Is NutriStack free to use?

Yes. Tracking, dose reminders, the label scanner, the interaction check and the research library are free. The optional Pro tier ($6.99 / month or $49.99 / year) adds the AI Coach.

Do I need an account?

No. NutriStack works without an account and your data stays on your iPhone. Signing in with Apple, Google or email adds cloud backup, so you can restore your routine on a new phone.

Is NutriStack medical advice?

No. NutriStack is an informational and organizational tool, not a medical service. Everything in the app and on this site is for general educational purposes. Always consult a qualified healthcare professional before changing your supplements or medications.

Where does the evidence come from?

Records may carry PubMed, regulatory, monograph, or review links, but attachment does not prove an exact claim. See the editorial policy and medical-review policy for the publication standard.

Which devices does it support?

NutriStack is an iPhone app for iOS 17 and later. There is no Android version yet. The guides, reports and schedule template on nutristackapp.com work in any browser.

How is NutriStack different from other supplement apps?

Most supplement apps either remind you or rate products. NutriStack also checks your supplements against your prescription medicines, and links every record to its source. We compare it honestly with SuppCo, Medisafe, MyTherapy and others in our app comparison.
