“COVID-19 Mortality Risk Correlates Inversely with Vitamin D3 Status,

a Mortality Rate Close to Zero Could Theoretically Be Achieved at 50 ng/mL 25(OH)D3: (125 nmol/L)

Results of a Systematic Review and Meta-Analysis


Blood calcifediol (25(OH)D3) levels correlate strongly with SARS-CoV-2 infection severity

Cause or effect?

Strength of our immune system,

More or less neglected by the responsible authorities

Nutrition, physical fitness, recreation, sleep

Widespread vitamin D deficiency

Data collected March 2021


Systematic literature search

Retrospective cohort studies (1)

Clinical studies (7) on COVID-19 mortality rates versus D3 blood levels

Reported D3 blood levels pre-infection or on the day of hospital admission

Mortality rates, corrected for age, sex, and diabetes


Negative Pearson correlation of D3 levels and mortality risk

r = −0.4154, p = 0.0770

r = −0.4886, p = 0.0646

Combined data

Median D3 levels were 23.2 ng/mL (58 nmol/L)

Pearson correlation = −0.3989, p = 0.0194

Regression suggested a theoretical point of zero mortality at approximately 50 ng/mL (125 nmol/L) D3


The datasets provide strong evidence that low D3 is a predictor rather than just a side effect of the infection.

Despite ongoing vaccinations, we recommend raising serum 25(OH)D levels to above 50 ng/mL”
