It is HFMA policy to require its members to ensure that their products are manufactured according to Good Manufacturing Practice (GMP). Each HFMA member company is required, as a condition of membership, to declare that they adhere to GMP principles at relevant stages of manufacture & distribution.

A number of elements of GMP are envisaged by food legislation, particularly with respect to ‘Due Diligence’ to ensure compliance with both safety (e.g. food hygiene, prevention of contamination and other HACCP) and food information provisions (including the labelling, advertising and presentation of food supplements). For food supplements, these ‘food elements’ of GMP are required in addition to the basic principles of pharmaceutical GMP that are appropriate for the production of the dosage forms in which food supplements are usually presented.

For both general food products and food supplements, the HFMA expects all relevant legislation to be met. For food supplements, the HFMA bases its GMP standards on those included in the ‘Quality Guide for food supplements’ published by the European Federation of Associations of Health Product Manufacturers (EHPM).
