Summary
This trial is testing if different doses of vitamin D can help prevent people from getting COVID-19 or make the illness less severe.
Who is the study for?
This trial is for adults over 18 living or working in the Chicagoland area who are interested in using vitamin D to prevent COVID-19. They must be willing to take daily doses of vitamin D, attend quarterly blood tests, and complete surveys throughout the 9-month study. People with certain medical conditions like hyperparathyroidism, kidney stones, or high calcium levels can't join.
What is being tested?
The study aims to see if different doses of Vitamin D (low at 400 IU/day vs. moderate at 4,000 IU/day vs. high at 10,000 IU/day) affect the risk of getting COVID-19 among participants from Chicago communities over a period of nine months.
What are the potential side effects?
Potential side effects may include elevated calcium levels which could lead to kidney stones or digestive issues; however, these risks are generally low and will be monitored through regular blood tests during the trial.
