At normale nivåer av D-vitamin har positive effekter på helsen vår, og muligens også gir lavere risiko for covid, er ikke helt fjernt. Om det er et argument for å pælme i seg store mengder D-vitamin når du først har fått det, er vel heller tvilsomt.
Vitamin D deficiency is associated with higher risks for SARS-CoV-2 infection and COVID-19 severity: a retrospective case-control study
Patients with very low vitamin D levels (< 30 nmol/L) had the highest risks for SARS-CoV-2 infection and also for severe COVID-19 when infected-OR 1.246 [95% CI 1.210-1.304] and 1.513 [95% CI 1.230-1.861], respectively. In this large observational population study, we show a significant association between vitamin D deficiency and the risks of SARS-CoV-2 infection and of severe disease in those infected.

Whether vitamin D plays a causal role in COVID-19 pathophysiology or just a marker of ill health is not known]
