Retrospective 510 patients in Iran, showing lower risk of severity with vitamin D (statistically significant) and zinc (not statistically significant) supplementation. IR.TUMS.VCR.REC.1398.1063.
risk of severe case, 70.9% lower, OR 0.29, p = 0.02, treatment 131, control 379, adjusted per study, multinomial logistic regression, RR approximated with OR.
risk of hospitalization, 37.9% lower, RR 0.62, p = 0.11, treatment 28 of 131 (21.4%), control 143 of 379 (37.7%), NNT 6.1, adjusted per study, inverted to make RR<1 favor treatment, odds ratio converted to relative risk, binary logistic regression.

Objective: The coronavirus disease 19 (COVID-19) is a highly transmittable and pathogenic viral
infection, causes severe acute respiratory syndrome and was spread throughout the world in early 2020.
The effects of vitamin and micronutrient supplements on the prevention and treatment of COVID- 19
seems challenging in scientific considerations. On the other side generally, experts warn against overconsumption of these supplements.
Materials and methods: This study aimed to investigate the vitamin and micronutrient supplementation
usage pattern in past history of patients with COVID-19 via a cross-sectional inquiry. Totally 510 patients
referring to the infectious disease clinic of Imam Khomeini Hospital in Tehran from March 2020 to May
2020 were recruited. The inclusion criterion was suspected patients for COVID-19 based on clinical
findings and CT scans of the lung. The infected patients included both inpatients (171) and outpatients
(339). Demographic information, clinical signs, and the supplement pattern use were collected through
a questionnaire and the data were statistically analyzed.
Results: Vitamin D3 intake was reported in 30% (103 patients) of outpatients and 16.5% (28 patients) of
hospitalized patients, which is statistically significant (P=0.001). It shows that, the frequency of vitamin D3
consumption in the outpatient group was higher than inpatient group. This significant difference has also
been shown in zinc consumption, in 29 patients (9%) outpatients versus 4 patients (2%) inpatients were
reported (P=0.007). Multi nominal regression showed that vitamin D3 intake has a supportive effect and
reduces the risk of exacerbation and worsening of the disease. (OR=0.291; 95% CI 0.102-.0834, P=0.022).
Conclusion: According to the results of the present study and the findings of other studies, considering
the supportive effect of vitamin D3 in reducing the severity of infectious diseases; Clinical trials with an
appropriate sample size are recommended to investigate the functional role of this vitamin in improving
viral diseases of the respiratory tract.
