Data publication built on the NIH Dietary Supplement Label Database

Background

PlainVitamins reads the NIH Dietary Supplement Label Database and sets every amount on a supplement label against every other product that lists the same ingredient, the FDA Daily Value and the adult upper limit. Pages are built with AI tools under its editorial policy: every figure comes from database queries over the NIH files, and a person at the studio that owns the site answers for what it publishes and reads every correction request. It takes no payment from the companies it covers.

How to use this site

PlainVitamins publishes reference material, data-driven pages, and explanatory tools. Use the source information, assumptions, limitations, and methodology shown on the individual page to decide whether it fits your situation.

Published information can summarize source data or provide an estimate; it is not professional financial, medical, legal, or engineering advice. For an important decision, compare the relevant page with a primary source or a qualified professional.

How information is presented

Pages that present data or estimates identify the available source, method, and material limitations. Results can differ from real-world outcomes because inputs, rules, rates, rounding, data coverage, and individual circumstances vary.

The methodology page explains the site-level approach and limitations. Check the source information on the page you are using rather than treating site-wide wording as a substitute for the current source.

Feedback
