Low serum vitamin D levels increase COVID-19 infection

Objectives:
Do low serum vitamin D levels increase risk of COVID-19 infection?

Study design:
This review article included 13 studies providing data for 14,485 participants.

Results and conclusions:   
The investigators found mean vitamin D levels in SARS-CoV-2 (COVID-19) negative patients was 17.7 ± 6.9 ng/mL compared to SARS-CoV-2 positive patients 14.1 ± 8.2 ng/mL [MD = 3.93, 95% CI = 2.84 to 5.02, I2 = 99%, p 0.001].

The investigators concluded low serum vitamin D levels are statistically significantly associated with the risk of COVID-19 infection. Supplementation of vitamin D especially in the deficiency risk groups is indicated.
