Republican congressman Glenn Grothman has introduced a House Resolution to recognize what he says is the significant role vitamin D may play in the fight against COVID-19. Grothman says infectious disease expert Dr. Anthony Fauci has recommended people take vitamin D supplements to lessen your susceptibility to infection, including the possibility of the coronavirus. Grothman says studies from Northwestern University and Trinity College in Dublin, Ireland, have shown that vitamin D deficiency may play a role in increasing the severity of symptoms and overall mortality rate in COVID-19 patients.
