Common dietary supplement label mistakes to catch early

Eight recurring review problems

1. Unclear statement of identity: the principal display panel does not clearly identify the product as a dietary supplement.
2. Net quantity copied without format review: the amount may be present but its wording, units, location, or prominence has not been checked.
3. Serving information conflicts: directions, serving size, and amounts per serving do not describe the same use.
4. Supplier data treated as finished labeling: a certificate or formula sheet does not prove the final Supplement Facts declaration, rounding, order, or Daily Values.
5. Other ingredients placed in the wrong area: dietary ingredients and non-dietary ingredients are mixed without applying their separate declaration rules.
6. Claims reviewed without context: headlines are checked while asterisks, footnotes, images, product names, marketplace copy, and implied meaning are ignored.
7. Business role is ambiguous: the label names a company but does not correctly describe whether it manufactured, packed, or distributed the product.
8. Old artwork reused: the label is copied from another formula, serving basis, market, or regulatory version without a fresh source review.

A better review order

Freeze the formula and serving basis first. Then review the principal display panel, Supplement Facts, other ingredients, business information, warnings, and every claim-bearing surface. Compare the final-size artwork with the actual package and keep the regulation version, source links, reviewer, and unresolved questions with the approval record.

What an automated check cannot prove

• OCR can miss small print, columns, curved labels, symbols, and claim-to-footnote relationships.
• A field marked present does not prove that its wording, placement, type size, or underlying evidence is adequate.
• A federal review does not establish complete state coverage or confirm that the product is lawfully marketable.
• No-error output only means the executed rules did not identify a blocking item from the confirmed facts.
