Vitamin D Testing and Treatment for COVID 19

Brief description of study

This study will measure vitamin D levels in adults with COVID 19. Participants with low levels of vitamin D will be entered into an open label trial of supplementation with vitamin D.

Detailed Study Description

Protocol for Part 1:

  • A single blood draw at SCNM to measure levels of vitamin D and other nutrients, comprehensive metabolic panel, and complete blood count with differential
  • Completing a medical history/symptom form
  • Completing a form about COVID-19 symptoms every 2 weeks for 6 weeks
  • Authorization for release of medical records related to COVID 19 testing and/or treatment.

Protocol for Part 2:

  • Take a vitamin D supplement daily for two weeks, at a dosage of 10,000 IU/day b.i.d. (age 18-69 years) or 15,000 IU/day t.i.d. (age 70+)
  • After two weeks of taking vitamin D, return to SCNM for a blood draw to remeasure levels of vitamin D, comprehensive metabolic panel, and complete blood count with differential. If vitamin D levels are still below 30 ng/ml, continue the dosage for 3 more weeks. If vitamin D levels are 30-49 ng/ml, continue at a dosage of 5000 IU/day. If vitamin D levels are 50+ ng/ml, stop supplementation.
  • Completing questionnaires about COVID 19 symptoms at 2, 4, and 6 weeks after treatment begins (5 minutes each time).
