Vitamin D could help fight off coronavirus

Vitamin D can help to fight off the coronavirus, according to a new study.

 Researchers from Trinity College Dublin say it plays a crucial role in preventing respiratory infections, such as Covid-19. 

Vitamin D is produced in the skin by exposing the body to 10 or 15 minutes of sun a day. 

One in eight Irish adults under the age of 50 is deficient in it.
