Vitamin D, government inaction

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 Methods 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 Results Negative Pearson correlation of D3 levels and mortality risk r = −, p = r = −, p = Combined data Median D3 levels were 23.2 ng/mL (58 nmol/L)
