This article presents results of analysis of existing regulatory documents and approaches to the legislative regulation of production and turnover of special dietary products for people with specific diseases in EU, Ukraine and Russian Federation. According to the EU legislation, production and turnover of food products for nutritional support of people during specific diseases and the rehabilitation period are regulated by the Commission Directive 1999/21/EC, 2009/39/ES, by Regulation Commission (EU) No 953/2009 and documents of Codex Committee. Special food products for people with specific diseases in Ukrainian legislation are classified as nutrition products for special dietary use and are regulated by the following Laws of Ukraine "On the safety and quality of food", "On ensuring of sanitary and epidemiological welfare of the population", "On Consumer Rights Protection", "On advertising" and by other non-legislative acts. According to the current legislation of the Russian Federation, the products for people with specific diseases are classified as healthy dietary food products. The basis of the legal framework are federal laws "On the quality and safety of food", "On the sanitary-epidemiological welfare of the populations", "On technical regulations and technical regulations of the Customs Union "On Food Safety" and "On the safety of certain types of specialized food products, including healthy dietary food products and therapeutic dietary food products".

The proposals for further harmonization of regulatory control in this area have been developed.
