The International Alliance of Dietary/Food Supplement Associations (IADSA) was founded in 1998 to address the globalisation of food supplement markets and increasing regulatory challenges. Bringing together food supplement associations from six continents, IADSA aims to build a sound legislative and political environment for the development of the food supplement market worldwide. This brochure provides an introduction to IADSA's role, structure and membership in relation to the growth of the global food supplement market and the regulatory framework.
