Abstract Background and aims Nutritional status is essential for the maintenance of the immune system, with malnutrition suppressing immunity. The aims of the current study were to assess the immune status of a group of Jordanian adults and to evaluate the association between vitamin C, vitamin D, and zinc consumption and the Immune Status during the COVID-19 pandemic. Methods A total of 615 adults Jordanian participants were enrolled in this study, an online- based cross sectional survey was used as a tool for this study. Data was collected by distributing the questionnaire form link through social media platforms. The association between ISQ score and the supplement intake pattern (daily, weekly, monthly and rarely) was assessed using multinomial logistic regression analysis, described as Odds ratio and 95% CI. Results Data have indicated that the majority of the participants did not take Vitamin D supplements during the pandemic (46.3%). Also, there was a significant association between the frequency of Vitamin D supplement intake and ISQ (r = 12.777; P < 0.05). Data showed that the majority of participants used vitamin C supplementation (49.4%). Also, there was a significant association between the frequency of Vitamin C supplement intake and ISQ (r = 12.797; P < 0.05). Data also have indicated that the majority of the participants did not increase their consumption of Zinc during the COVID-19 pandemic (55.6%). Conclusions The findings of this study suggest a significant association between the frequency of Vitamin D, and vitamin C supplement intake and ISQ. Nutritional status is essential for the maintenance of the immune system, with malnutrition suppressing immunity.
