Why an alphabetical letter index?

The alphabetical browse exists because most casual searches start from a known product or brand name. If you remember the bottle in your cabinet starts with "N", this is the fastest way to scan all matching products in the NIH Dietary Supplement Label Database (DSLD). The full directory contains 2,325 products under "N", sortable by name, newest entry, or brand. For comparing products within a category (vitamin D, fish oil, multivitamins), use the type-filtered listing instead. For brand-level analysis, jump to the brands directory.

Per-product detail pages show 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 DSLD records include only structural ingredient lists without the per-row Supplement Facts panel; in those cases the detail page renders "Not disclosed on label" rather than a fabricated estimate. Editorial commentary and ingredient context is compiled by our editorial team. Inclusion in the directory is a label record, not an FDA endorsement, quality verification, or clinical efficacy claim. Always verify amounts on the physical label and consult a healthcare provider before starting any supplement, particularly if pregnant, nursing, taking prescription medication, or managing a medical condition.

Every figure on PlainVitamins is rendered directly from the NIH Dietary Supplement Label Database (DSLD), no number is typed in by an editor. This page draws directly on the NIH DSLD, no figure is typed in by an editor. See our editorial standards & corrections policy, the methodology behind these numbers, or report a data error.
