About this directory

This page lists every dietary supplement product label currently cataloged in the National Institutes of Health (NIH) Office of Dietary Supplements (ODS) Dietary Supplement Label Database (DSLD), sorted alphabetically by product name. Use the alphabetical index above to jump to products starting with a specific letter, or switch the sort order to surface the newest entries or to group products by brand.

Each row links to a product detail page that breaks down the declared ingredient list, serving size, market status, and Daily Value (DV) percentages, when those values were submitted to the NIH on the original label filing. Many products in the DSLD include only a structural ingredient list without per-row Supplement Facts panel data; in those cases the detail page renders "Not disclosed on label" rather than a fabricated estimate. We do not invent values, fill gaps with industry averages, or substitute manufacturer-website data for what the NIH cataloged.

How the DSLD is built

The NIH DSLD is updated on a rolling basis as new label submissions arrive from manufacturers and as existing labels are revised. The database is the most comprehensive government-maintained record of supplement label information sold in the United States, and unlike third-party retail catalogs, DSLD records are collected systematically without commercial filtering. The database itself stretches back to 2011, so directory rows include both currently-on-market and historical (off-market) labels, the off-market labels are preserved for research, consumer historical lookup, and tracking how formulations have changed over time.

Inclusion of a product in the DSLD is a documentary record, not an FDA endorsement. Dietary supplements in the United States are regulated under the Dietary Supplement Health and Education Act (DSHEA, 1994), which does not require pre-market FDA approval for safety or efficacy. Manufacturers are responsible for ensuring their products are safe and that label claims are truthful and non-misleading; the FDA's role is largely post-market enforcement. A product appearing in this directory has had its label catalogued; it has not necessarily been independently tested for ingredient potency, bioavailability, or contamination.

How to use this directory

For comparing products within a class, for example, vitamin D supplements, fish oil capsules, or multivitamin formulas, start from the type-filtered supplement directory rather than this alphabetical list. From a product detail page, you can navigate to the brand profile to see the manufacturer's full lineup, or click an ingredient name to see all supplements that contain that nutrient along with NIH ODS dosing context (RDA, UL, unit conversions, drug interactions where applicable).

Researchers and journalists who need bulk programmatic access to the DSLD should fetch directly from the source at dsld.od.nih.gov; PlainVitamins is a derived presentation of that public dataset and does not republish raw bulk exports. Educational use of individual product profiles (homework, school projects, journalism, consumer research) is encouraged and requires no attribution beyond crediting the NIH ODS as the original source.

Data limitations

Three caveats worth noting. First, the DSLD captures what manufacturers self-declare on the label as filed with the NIH; it does not reflect independent laboratory verification. Studies of supplement potency have historically found discrepancies between labeled amounts and laboratory-measured contents in some categories, and third-party verification programs (USP Verified, NSF Certified for Sport, ConsumerLab) exist precisely because of this. Second, formulations can change without prompt updates to the DSLD, always check the physical bottle label for the most current ingredients and amounts before consumption. Third, the DSLD captures only US-marketed dietary supplements; products marketed exclusively outside the United States are not in the database.

PlainVitamins is an informational reference compiled by our editorial team. We do not recommend, endorse, or rank supplements by perceived quality. Decisions about supplement use should be made in consultation with a qualified healthcare provider, particularly for individuals taking prescription medication, those who are pregnant or nursing, individuals with kidney or liver conditions, and anyone planning surgery (some supplements affect bleeding risk).

A note on directory completeness

The DSLD does not capture every dietary supplement marketed in the United States. Some manufacturers have not submitted labels for cataloging, particularly very small private-label brands, products marketed only through limited regional channels, and short-lived limited-edition formulas. The directory totals shown on this page reflect only what the NIH ODS has cataloged at the time of our latest database snapshot, not a census of all possible supplements ever sold. New product submissions arrive on a rolling basis as manufacturers update their filings.

Brand profiles are normalized at indexing time to handle common variations in capitalization and abbreviation, so a search for "GNC" surfaces records cataloged variously as "GNC", "GNC General Nutrition Center", and similar variants under a single canonical brand record. Ingredient indexing is a similar normalization step: the same chemical compound (e.g., vitamin D3) may appear on labels under multiple ingredient names (cholecalciferol, vitamin D-3, vitamin D3), and our per-ingredient pages aggregate these. When the chemical form matters for your clinical question (D3 vs D2, methylcobalamin vs cyanocobalamin, magnesium glycinate vs oxide), check the individual product page where the manufacturer's original wording is preserved.
