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 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.
