Vitamin D doesn’t prevent COVID-19: study
There's no link between vitamin D levels and development of coronavirus or its severity, researchers say
Supplementation with vitamin D to prevent coronavirus is not supported by a genetic study, which finds no link between genetically predicted levels of the 25-hydroxy vitamin D and development of the disease.
Canadian researchers say theirs is the “strongest evidence” to date that vitamin D does not provide protection against COVID-19.
Their results show no association between genetically predicted 25-OHD levels and infection susceptibility, hospitalisation, or severe disease.
“Hence, vitamin D supplementation as a means of protecting against worsened COVID-19 outcomes is not supported by genetic evidence,” they wrote in Plos Medicine.
