All Swanson® brand products are produced by Good Manufacturing Practices (GMP) compliant manufacturers that meet specific standards for quality and potency. We require that our manufacturers develop and formulate products that’ll maintain their quality for the expected timeframe.
One of our primary goals is to provide you with the freshest products possible. We bottle all Swanson brand capsules, tablets and softgels in our own facility, which allows us to control our inventory and deliver guaranteed freshness.
Swanson brand products include a Best By date and/or a Manufactured (MFG) date.
A “Best By” date indicates that the product will successfully meet the claims made on its label up until the date given. Our products undergo rigorous stability testing to determine the most accurate dating for our finished products.
A “Manufactured” date states when the product was bottled. In most cases, supplements are considered stable at full potency for 2-3 years from the manufactured date. Most liquid supplements and probiotics are typically stable for one year from the manufacture date. This does not include food items or topical/cosmetic products (creams, lotions, shampoo, etc).
