    Background. Vitamin D occurs in two forms: D2 (ergocalciferol) and D3 (cholecalciferol). Deficiency of vitamin D can lead to rickets in children, while in adults to osteoporosis, depression and multiple sclerosis. The aim of the pilot study was to analyze dietary supplements in terms of the actual content of vitamin D3. Material and methods. The object of the study was ten random samples of dietary supplements from different manufacturers containing in their composition different values of vitamin D3. The manufacturers included a declaration on the content of vitamin D3 on the packaging. The actual content of vitamin D3 was determined using high-performance liquid chromatography (HPLC). The content of vitamin D3 was determined based on a standard curve. Sigma Aldrich’s Cholecalciferol standard was used. Results. In all the analyzed dietary supplements, the actual content of vitamin D is much lower than declared by the manufacturer. The carried-out tests revealed that the content of vitamin D3 in the analyzed supplements varied from 1.02 to 59.56 μg. In three cases borderline low values of vitamin D3 were noted. Furthermore, supplement 6 and 9 contained too low dosage of vitamin D3 to supplement a daily demand of an organism for this vitamin. Conclusions. Controlling the shortage of vitamin D in an organism decreases the risk of occurrence of civilization diseases. The results of own pilot studies and studies of other authors prove that this type of research should be continued in a wider scope on various food categories.

    Health and nutritional behavior of a selected group of south-eastern Poland patients: a pilot study
    (Akademia Bialska Nauk Stosowanych im. Jana Pawła II, 2022-12-24) Domański, Maciej ; Domańska, Anna ; Chęcińska-Maciejewska, Zuzanna ; Lachowicz-Wiśniewska, Sabina ; Żukiewicz-Sobczak, Wioletta ; Weiner, Marcin
    Background. The growing number of people with excess body weight is one of the most important global health issues. The increase in the number of people with excess weight and obesity leads to a shortened life expectancy. Material and methods. The aim of this pilot study was to use a questionnaire survey to determine the lifestyle of the people in a group of 84 Polish patients from south-eastern Poland, including diet, physical activity, and health. The pilot studies were carried out from December 2021 to January 2022 in a family doctor’s clinic among people in search of advice, who willingly volunteered themselves for the study. Results. The results of the study showed that 33% of women and 44% of men have excess body weight. Economic status statistically significantly affects the incidence of overweight and obesity. However, the level of education does not have a statistically significant effect on body weight. The irregularity of meals among the respondents was often explained by irregular work and many responsibilities. Our research also showed a low physical activity of the studied population. Conclusions. Improper nutrition combined with other anti-health behaviors make it significant to introduce intensive health education programs.
