Background. In recent years, dietary supplements have become the subject of interest among consumers, food producers and the pharmaceutical industry. Dietary supplements are not  medicinal products and are not considered as such. However, the majority of society in many countries treats dietary supplements as equal to medicinal products. The article draws attention to  innovative dietary supplements containing many ingredients from exotic plants, which have not been used in supplements to such an extent so far. The aim of this study was to determine the  physicochemical properties of multi-ingredient Purella Super Mix dietary supplements. These supplements are produced by Purella Food, and the series includes five products with various  advertised effects on the human body. Purella Super Mix products were characterized in terms of their composition and the resulting importance for human health. A number of  physicochemical analyzes of Purella Super Mix were carried out, which have not been published to this extent before. Water content, water activity, bulk density and the angle of repose and cone  angle were measured, as well as the Hausner ratio and the Carr index were determined. These properties deliver important information both for the technological process and for  subsequent stages of the product life cycle.
Results and conclusions. The results of the research on the physicochemical properties of innovative multi-ingredient dietary supplements can be used to predict the durability of these products  and to design the packaging that takes into account the behavior of supplements during storage. The results obtained may also constitute the basis for further research on improving the  composition and properties of multiingredient dietary supplements.
