High intakes of vitamins A, E, and D are linked to fewer respiratory illnesses, experts have suggested, as they called for further research into their effect on coronavirus.
A new long-term study involving 6,115 adults starting in 2008 suggests that taking the vitamins either through food or as a supplement may reduce the number of respiratory complaints.
It comes after Health Secretary Matt Hancock ordered a review into the use of vitamin D for preventing coronavirus after previously saying it did not appear to have any effect.
Those taking part in the latest study self-reported their vitamin intake and any respiratory issues, rather than them being diagnosed by a doctor.
