Good Storage & Distribution Practices of Food Supplement Products
A Food supplement is defined under legislation as foodstuffs the purpose of which is to supplement the normal diet and which are concentrated sources of nutrients or other substances with a nutritional or physiological effect, alone or in combination, marketed in dose form, namely forms such as capsules, pastilles, tablets, pills and other similar forms, sachets of powder, ampoules of liquids, drop dispensing bottles, and other similar forms of liquids and powders.

The Ministry of Public Health of each countries stresses the importance of adhering to this guideline by all parties involved in any aspect of the storage and distribution of food supplement products, as relevant to the particular role that they play, from the premises of the manufacturer of the product to the person dispensing or providing food supplement products directly to a consumer or his agent.
