Swanson products are often marked with a Manufacture (MFG) date rather than an Expiry (EXP) date. Unless specified by an expiry date, products are considered stable at full potency for two years from the MFG date. Exceptions to this include liquids and probiotics which are considered stable for one year from the MFG date.
The Manufacture Date printed on the label represents the date upon which the product was produced and is your assurance of quality and freshness. Often, on a dark coloured bottle, the MFG date will be printed on the bottom of the bottle. All Swanson products are produced by approved Good Manufacturing Practices (GMP) compliant manufacturers to meet specified standards for quality and stability.
Swanson will continue to test and study their products to assure they meet the expected shelf-life (in most cases two years from the date of manufacturer). This change in label dating is due to a modification of regulatory requirements and does not represent a change in the quality of Swanson brand products.
Rest assured that there has been no change to the ingredient selection or manufacturing procedures and Swanson brand products continue to meet and exceed the most stringent quality control standards. Swanson will continue to require that their manufacturers develop and formulate products to maintain their quality for the expected timeframe (two years for most products, one year for probiotics and some liquid products).
This change in product dating applies only to Swanson brand supplements and does not include food items or topical or cosmetic products (creams, lotions, shampoo, etc.)
