Beauty in a tablet - Public knowledge about nutraceuticals

Abstract

Subject of research: Dietary supplements are products which supplement a proper diet with vitamins, bioelements and other biologically active compounds. Nutricosmetics contain vitamin, mineral and biologically active compounds that have a positive effect on the appearance of the skin, nails and hair. The constantly growing consumption of dietary supplements, including preparations improving the condition of the skin of the hair and nails, promotes the creation of new preparations, but does not increase public awareness of the products used. Research objective: The aim of the study was to verify patients' knowledge of dietary supplements, with particular emphasis on preparations improving the condition of skin, hair and nails, determining the amount of supplements taken and assessing the awareness of the combinations used, as well as determining the factors determining the choice of a particular preparation. Materials and methods: The survey was conducted from December 2019 to April 2020 with the participation of a random group of 170 respondents, using the author's anonymous questionnaire containing 33 questions. Results: Based on the results obtained, it can be said that 95% of respondents know the definition of a dietary supplement, but only 47% of respondents know that they are intended for healthy people, 54% of respondents declare taking dietary supplements that support the condition of the skin, hair and nails, 1/3 of respondents when choosing a preparation do not pay attention to whether it is a medicine or a dietary supplement, and 40% of respondents are not aware of the differences resulting from the different registration of both preparations. Over 70% of respondents buy dietary supplements at the pharmacy, but only a quarter of respondents use the pharmacist's professional advice. Almost 40% of respondents simultaneously use two or more dietary supplements, without being aware of the possibility of overdose of active substances contained in the preparations taken. Only half of the respondents are satisfied with the effects achieved thanks to the use of dietary supplements that improve the condition of the skin, hair and nails. Conclusions: Respondents have basic knowledge about dietary supplements used, but constant public education is needed regarding specialist knowledge regarding the quality and method of taking dietary supplements.
