Re: Coronavirus - is low vitamin D a factor - vitamin D and respiratory conditions

A number of papers suggests that low vitamin D impacts a number of respiratory condition risks including mortality. As ever things are complex and more research is needed, but there is quite a large body of general evidence and results suggesting a protective factor for vitamin D in respiratory disease, and the results are thought provoking.

Consistent with a role in respiratory conditions Vitamin D appears to have a role in tight cell junction function including in the lung and digestive system.

Regulation of tight cell junction function is also a factor in spread in cancer as discussed elsewhere
