Do Supplements Expire? How to Read a Date on the Label

A date on a supplement bottle can invite unnecessary drama. Is it an expiry date? A best-before date? A mysterious number invented to make your cupboard feel judged? The useful answer starts with the label itself.

Are dates required on supplement labels?

FDA’s Dietary Supplement Labeling Guide says that expiration dating is not required on labels for dietary supplements. A firm may include date information when it is supported by valid data and is not false or misleading. [1]

That means you may see a date on one product and not on another. Its presence is information to read, not a reason to make assumptions about every supplement in the universe.

Start with the words around the date

Before trying to interpret a string of numbers, check the wording printed beside it. Look for language such as “best by,” “use by,” “expires,” or a storage instruction. The package is the product-specific source; a general article cannot tell you what a particular manufacturer intended without that context.

• Read the exact wording next to the date.
• Check the manufacturer’s storage directions.
• Keep the package information with the product when possible.
• Ask the manufacturer if the code or date format is unclear.

Do not turn a date into a safety verdict

A date by itself does not explain every product-quality question. If a package is damaged, its seal is broken, its appearance has changed, or the directions are unclear, the sensible next step is to contact the manufacturer rather than trying to decode it through vibes and a kitchen light.

FDA advises consumers to read supplement labels carefully and to contact the manufacturer when they need more detailed information about a specific product. [2] For individual health questions, medicines, pregnancy, nursing, allergies, or symptoms, speak with an appropriate qualified professional.

Dates are only one part of the label

A clear label has more to offer than a date: the product name, ingredient information, Supplement Facts panel, directions, warnings, and manufacturer details all provide context. FDA’s labeling guide identifies these as key label statements for dietary supplements. [1]

The best label-reading habit is wonderfully unglamorous: read the small print before the product becomes a mystery novel.

The short version

FDA does not require expiration dating for dietary supplements, but a company may use a date when it is supported and not misleading. Read the words around the date, follow the package directions, and ask the manufacturer when you need clarity.
