SUMMARY
The constant increase in the number of dietary supplements and the demand for them, as well as the progression of self-medication with the use of over-the-counter medicines, raises questions about their effectiveness, safety and bioequivalence. There are also questions about the criteria for ingredients, production, standardization and registration of finished medicines and dietary supplements.The current legislation of Ukraine regulating the production, quality and circulation of finished medicines harmonized with the EU puts forward requirements for providing the population with quality imported / domestic medicines. Regarding dietary supplements, the procedure of harmonization of the legislation of Ukraine with the EU has started, which in the future should lead to improvement of the quality of these remedies and increase of control from the state.
