Vitamin D plays a role in the body’s immune system and is known to enhance the function of immune cells. In this case, vitamin D inhibits some of the inflammation that can make COVID-19 more severe. The is study aims to determine the serum levels of vitamin D, calcium, and phosphorus in COVID-19 patients. Methods: This was a cross sectional study conducted during the period from January 2021 to July _____________________________________________________________________________________________________ *Corresponding author: E-mail:; Asian J. Res. Biochem., vol. 11, no. 2, pp. 29-38, 2022 Ali et al.; Asian J. Res. Biochem., vol. 11, no. 2, pp. 29-38, 2022; Article no.AJRB.94190 2021. 50 COVID-19 patients as a case study and 50 healthy individuals as a control group were included in this study. Blood samples were collected from the study group and measured for vitamin D using Enzyme-linked immunosorbent assay (ELISA) technique. Calcium and phosphate were measured by the Cobas 6000 fully automated analyzer (Roche, Germany). Results: The study result showed that in COVID-19 patients, vitamin D (27 ± 5 ng/mL), p-value = 0.000, and calcium (10.2 ± 4 mg/dL), p-value = 0.000, in comparison with control. There was a correlation between vitamin D (r = -.771; p =.000) and calcium (r = -.752; p =.000) and the severity of disease. Conclusions: According to our research, vitamin D deficiency may increase the risk of developing COVID-19 and the risk of developing severe illnesses. Keywords: COVID -19; vitamin D; calcium; phosphate.
