Vitamin D Protects Against Covid: A Study That Proved What A Lot Of Us Instinctively Knew

A total of 72 observational studies, covering 1,976,099 patients, met the criteria for inclusion. Compared to those with sufficient vitamin D, the odds of developing COVID-19 among those with deficient or insufficient vitamin D levels were 1.46 times higher.

Their risk of severe disease was also 1.9 times higher, and their risk of death 2.07 times higher. One potential drawback was that all studies ranked “high” for risk of bias. The studies also differed in their definitions of severe illness and vitamin D deficiency/insufficiency, making absolute comparisons difficult.

  • Since December 2021, four large systematic meta-analyses have been published, looking at either vitamin D levels, supplementation or both. In all cases, the data consistently show that low vitamin D levels raise your risk of COVID while higher baseline levels and/or supplementation lowers all risks by 1.5 to three times
  • In the first of these four meta-analyses, the odds of developing COVID-19 among those with deficient or insufficient vitamin D levels were 1.46 times higher than those with sufficient vitamin D. Their risk of severe disease was also 1.9 times higher, and their risk of death 2.07 times higher
  • In the second study, the odds of ICU admission based on vitamin D status were 2.63 times higher among those with severe vitamin D deficiency, 2.16 times higher among those with deficiency, and 2.83 times higher among those with insufficient levels. Mortality was also much higher in all patients with low levels
  • In the third analysis, only 12.19% of COVID patients who received vitamin D required ICU admission, compared to 26.27% of those who did not get vitamin D
  • The fourth and most recent analysis found “significant associations of vitamin D supplementation with COVID-19, encompassing risks of disease worsening and mortality,” especially in seasons characterized by vitamin D deficiency and in patients with mild to moderate infection

Read the whole thing here. I didn’t do the study, but I know I’ve seen enough corroborating evidence that I’ve been taking it since I first heard of Covid.

One last nugget to send you over for the rest….

Therapeutic Role of Vitamin D in COVID

In the first of these four meta-analyses, “Prognostic and Therapeutic Role of Vitamin D in COVID-19: Systematic Review and Meta-Analysis,”3 published December 11, 2021, the researchers sought to determine “the association between vitamin D deficiency/insufficiency and susceptibility to COVID-19, its severity, mortality and role of vitamin D in its treatment.”

A total of 72 observational studies, covering 1,976,099 patients, met the criteria for inclusion. Compared to those with sufficient vitamin D, the odds of developing COVID-19 among those with deficient or insufficient vitamin D levels were 1.46 times higher.

Their risk of severe disease was also 1.9 times higher, and their risk of death 2.07 times higher. One potential drawback was that all studies ranked “high” for risk of bias. The studies also differed in their definitions of severe illness and vitamin D deficiency/insufficiency, making absolute comparisons difficult. That said, the authors concluded.

Why did the doctors recommend the jab instead of a cure? Of course I know to save their jobs because it sure as shooting wasn’t about science.
