Objectives: The consumption of dietary supplements might prevent the deficiency of necessary nutrients. On the other hand, in cases of overconsumption, adverse effects might occur. In Lithuania, the COVID-19 pandemic provoked an increase in the consumption of dietary supplements. The aim of this study was to reveal the post-pandemic trend of the consumption of dietary supplements among the working-age residents of Lithuania with respect to social and demographic factors and food selection criteria.

Methods: A cross-sectional observational study was performed. In total, using the same methods, 3,200 residents were surveyed: 1,600 in 2021 and 1,600 in 2022. Both samples were representative for Lithuania and included residents of Lithuania aged from 18 to 64 years. According to socio-demographic factors (sex, age, level of education, type of place of residence, marital status, number of family members, presence of children under 18 years old in the household, employment status, level of income), COVID-19 experience (presence of COVID-19 cases among friends or relatives, severeness of COVID-19) and food selection criteria (health strengthening, other) the prevalence of the consumption of dietary supplements was compared between the samples.

Results: The consumption of dietary supplements accounted for 78.1% and 71.6% of the respondents in 2021 and 2022, respectively (p < 0.001). After the COVID-19 pandemic, the prevalence of the consumption of dietary supplements decreased in the majority of social and demographic groups analysed in this article (p < 0.05). The consumption of dietary supplements remained unchanged among those who selected foods for health strengthening (p = 0.098).

Conclusions: The prevalence of the consumption of dietary supplements decreased after the COVID-19 pandemic in most social and demographic groups except those who selected foods for health strengthening.
