Nutrients play a vital role in the defense against infectious diseases and the regulation of inflammation; however, little is known with regards to COVID-19. We measured concentrations of vitamins B1, B6, B12, folate, vitamin D (25-hydroxyvitamin D), selenium, and zinc in 50 patients with COVID-19. Vitamin D deficiency was shown in 76% of patients and selenium deficiency in 42%. There was a significant difference compared to a control group of 150 people (vitamin D deficiency 43.3%). Among 12 patients with respiratory distress, 11 (91.7%) had one or more nutrient deficiency. The relationship between immunity and nutrition is well known and its role in coronavirus disease 2019 (COVID-19) is also being paid great attention. However, the nutritional status of COVID-19 patients is unknown. Vitamin B1, B6, B12, vitamin D (25-hydroxyvitamin D), folate, selenium, and zinc levels were measured in 50 hospitalized patients with COVID-19. Overall, 76% of the patients were vitamin D deficient and 42% were selenium deficient. No significant increase in the incidence of deficiency was found for vitamins B1, B6, and B12, folate, and zinc in patients with COVID-19. The COVID-19 group showed significantly lower vitamin D values than the healthy control group (150 people, matched by age/sex). Severe vitamin D deficiency (based on a cut-off of ≤10 ng/dl) was found in 24.0% of the patients in the COVID-19 group and 7.3% in the control group. Among 12 patients with respiratory distress, 11 (91.7%) were deficient in at least one nutrient. However, patients without respiratory distress showed a deficiency in 30/38 cases (78.9%; p =  0.425). These results suggest that a deficiency of vitamin D or selenium may decrease the immune defenses against COVID-19 and cause progression to severe disease. However, more precise and large-scale studies are needed.
