Health & Appropriate-Use Disclaimer
PlainVitamins makes dietary-supplement label data legible using the NIH Dietary Supplement Label Database. Please read how to use this information responsibly before acting on it.
Informational Only — Not Medical Advice
PlainVitamins is for general informational purposes only. Nothing on this site is medical, nutritional, pharmaceutical, or professional advice, and it is not a substitute for the judgment of a qualified healthcare provider. We do not recommend, endorse, rank for quality, or evaluate the safety or efficacy of any supplement, ingredient, or brand. Before starting, stopping, or changing any supplement — especially if you are pregnant or nursing, have a medical condition, or take prescription medication — consult a physician, pharmacist, or registered dietitian.
What This Data Is — and Is Not
The figures on PlainVitamins come from the NIH Dietary Supplement Label Database (DSLD), which records information printed on supplement labels. Label data is not laboratory data: independent testing has found that some products contain more, less, or different ingredients than their labels state. Presence in the DSLD does not mean a product has been tested, verified, approved, or found safe. Dietary supplements are not reviewed by the FDA for efficacy before they are marketed, and the FDA does not approve supplements before sale.
Not Affiliated With NIH, the FDA, or Any Brand
PlainVitamins is an independent publication. We are not affiliated with the National Institutes of Health, the Office of Dietary Supplements, the U.S. Food and Drug Administration, or any supplement manufacturer, brand, or retailer. References to these organizations identify the source of public data only and do not imply endorsement in either direction.
Data Reflects DSLD Release Cycles
Figures reflect the most recent DSLD source files we have processed. The DSLD records a product's label at the time of entry, so a formulation shown here may not match a manufacturer's current product; serving sizes, amounts, and ingredients can change without the database being updated immediately. Always confirm a product's current label with the manufacturer, and verify health information at ods.od.nih.gov before making a decision.
Reporting a Problem With a Supplement
If you experience a harmful reaction to a dietary supplement, stop using it and seek medical care. You can report a serious adverse event to the FDA through MedWatch / the Safety Reporting Portal. To report a figure on this site that looks wrong, see our corrections process.
Limitation of Liability
PlainVitamins provides this information "as is" without warranty of any kind. We make no guarantee that the data is complete, current, or error-free, and we are not liable for decisions made on the basis of information presented here. Your use of the site is governed by our terms of use.
