COVID-19: Vitamin A nasal drops to be trialled to help restore smell loss

A 12-week trial will look at whether nasal drops can help those who lost their sense of smell after having COVID-19. The 'Apollo trial' will treat people who have experienced a loss of smell or altered sense of smell because of coronavirus using vitamin A nasal drops. The University of East Anglia (UEA) said research from Germany has shown the potential benefit of the vitamin, and its team 'will explore how this treatment works to help repair tissues in the nose damaged by viruses'. They hope the trial 'could one day help improve the lives of millions around the world who suffer from smell loss, by returning their fifth sense'.
