As a service to our community, the UMDF Scientific and Medical Advisory Board continues to monitor credible reports about COVID-19 illness and provide periodic updates. Recent news reports regarding the use of Vitamin D in those with vitamin D deficiency possibly lessening the severity of COVID-19 illness are preliminary and yet unproven. Measuring vitamin D levels (25-hydroxy D) is easy to perform and your provider can recommend the proper dose of vitamin D, if necessary. Vitamin D can have adverse health effects if consumed in improper dosages. The UMDF SMAB strongly suggests patients or caregivers discuss all medication or supplement additions or changes with their health care provider.
