    Shelf-Life Recommendations for Supplements
    January 2014

    As part of good manufacturing practice, products should meet specifications throughout their shelf-life, and are generally labelled with a date through which the product’s potency is assured by the supplement manufacturer. These guidelines on shelf-life recommendation provide information on factors that could affect shelf-life, parameters to be taken into account for shelf-life testing and sources of data that can be used or need to be developed to assist manufacturers in defining and supporting the shelf-life dates of their products. The publication is also available in Spanish : Recomendaciones sobre la vida útil de los complementos alimenticios
