NCT ID NCT04868903

Summary

This study aimed to see if taking higher daily doses of vitamin D could help prevent people from getting COVID-19. Researchers in Chicago enrolled nearly 1,500 adults and randomly assigned them to take either a standard low dose (400 IU) or a much higher dose (4,000 or 10,000 IU) of vitamin D daily for nine months. They tracked who got sick with COVID-19 to see if the higher doses offered better protection.
