Vitamin D is recognized to be critical in several physiologic functions. Therefore more attention should be given to supplementation and normal level maintaince.
Regardless of whether vitamin D protects against COVID-19, adequate levels are important for bone health. “Avoiding vitamin D deficiency is always a goal,” Ross wrote. “If the diet doesn’t include vitamin D fortified milk or natural products like fish, then a supplement of the RDA [recommended dietary allowance] amount (600-1000 IU per day) provides good assurance. I consider this a ‘good idea,’ but I don’t want to leave the impression that diet cannot be sufficient.”
In this single-center, retrospective cohort study, likely deficient vitamin D status was associated with increased COVID-19 risk, a finding that suggests that randomized trials may be needed to determine whether vitamin D affects COVID-19 risk.
A regular bolus of vitamin D supplementation was associated with less severe COVID-19 and better survival in frail elderly. It is therefore recommended that the patient take the supplements.
Vitamin D deficiency may cause immune dysfunction. Therefore Novel_Sars-viruses have an easier time causing respiratory injury.
“A greater proportion of vitamin D-deficient individuals with SARS-CoV-2 infection turned SARS-CoV-2 RNA negative with a significant decrease in fibrinogen on high-dose cholecalciferol supplementation.”
to paraphrase the authors: “If vitamin D does, in fact, reduce the severity of COVID-19 then supplements would offer a relatively easy option to decrease the impact of the pandemic.”
