Vitamin D and COVID-19
Recent research surrounding COVID-19 positivity rates and infection severity has examined a possible connection to vitamin D levels. In one study that compared hospitalized patients with a control group, vitamin D blood levels were lower in hospitalized COVID-19 patients. This finding suggests that low vitamin D levels could play a role in the severity of the disease.
Vitamin D deficiency has also been significantly associated with increased risk for COVID-19. According to a study from the University of Florida that was published in the The International Journal of Applied and Basic Nutritional Sciences, patients with vitamin D deficiency were 4.6 times more likely to be positive for COVID-19 than patients without a vitamin D deficiency. The same study found that patients with vitamin D deficiency were 5 times more likely to be infected with COVID-19 than patients with no deficiency (after adjusting for age groups).
Another analysis of patient data showed that higher COVID-19 positivity rates are associated with lower vitamin D levels in the blood, reardless of race/ethnicity, sex, or age. The study indicates that when low vitamin D levels exist, infection is more likely.

Frequently Asked Questions
Who needs to take an at-home vitamin D test?
Too much or too little vitamin D can harm your health, so it’s important for all individuals to regularly monitor vitamin D levels in their blood. Fatigue, bone pain, thinning hair, muscle pain, and mood changes (such as depression) can be signs that you have low vitamin D levels, and the only way to identify your levels is to get tested.
What are some natural sources of vitamin D?
You can get vitamin D from the sun or in small amounts from your regular diet. Foods rich in vitamin D are egg yolks, milk, red meat, fish oil, mushrooms, and liver meat. Many foods are also fortified with vitamin D, which means that it doesn’t naturally contain much vitamin D so it was added to prevent a common deficiency.
|Cooked salmon (3 oz)||3 oz||444 IU|
|Low fat milk, 1 percent, fortified with protein & vitamins A & D||8 oz||98 IU|
|Egg yolk||1 large||37 IU|
|Ground beef (3 oz)||3 oz||7 IU|
|Mushrooms, white, raw (1 cup)||8 oz||5 IU|
What are the common causes of vitamin D deficiency?
Clothing, sunscreen, and working indoors decreases your exposure to sunlight and limits your body’s ability to use the power of sunlight to make vitamin D. Your diet also plays a role in your vitamin D deficiency, especially if you follow a vegan or vegetarian diet.
Several medical conditions and medications can also contribute to vitamin D deficiency by decreasing the vitamin’s absorption in the gastrointestinal tract. If you’re worried about your vitamin D levels, get an at-home vitamin D test from empowerDX to get the health answers you need.
What’s in my kit?
Each kit contains one lancet, three test tubes, a biohazard bag, (2) 6 oz ice packs, an insulated shipping envelope, alcohol pad, gauze pad, bandage, FedEx return envelope, and step-by-step instructions.
Should I take vitamin D supplements?
“If you’re deficient in vitamin D, that does have an impact on your susceptibility to infection. I would not mind recommending, and I do it myself, taking vitamin D supplements”
-Dr. Anthony Fauci, director of National Institute of Allergy and Infectious Diseases
If you have a vitamin D deficiency, supplements are one way you can increase your intake. However, Vitamin D levels should be monitored when taking supplements because too much vitamin D can be harmful.
Note: There are some medical conditions where taking vitamin D can cause adverse effects; therefore, we always recommend a discussion with your primary care physician before taking any supplements.
Do I need to stop taking my supplements or medications before the test?
We recommend that you do not discontinue any medications or supplements without contacting your healthcare provider first.
Do I need a prescription before ordering one of your tests?
Nope! You don’t need a requisition or prescription from your physician to order one of our test kits. A requisition is created and approved by our Licensed Ordering Provider Network when you register your test. This service comes at no additional charge to you.
How long is my finger prick sample stable after I collect it in the microtainer tube?
You should ship your sample the same day you collect it. To ensure stability of the sample, we recommend you collect and ship samples Monday through Thursday only.
Is my test kit covered by health insurance?
Right now, we only accept health insurance for the At Home COVID-19 Nasal PCR Test.
For all other test kits, we can’t bill insurance directly. However, you can take the receipt and submit it to your insurance for reimbursement. We will be happy to provide a paid invoice and HSA/FSA receipts to help you seek reimbursement. We can’t guarantee coverage as this depends on your insurance provider.
Please let us know if you need any other documentation. Our team is here to help.
What will my results tell me?
Once you’ve sent your sample back to the lab, we’ll send you your results in 48 hours. Your results will tell you how much vitamin D was in your sample. Below are the values used by our lab to determine how to categorize your vitamin D levels:
- Low: <30 ng/mL
- Mid: 30–100 ng/mL
- High: >100 ng/mL
Can I bring my results to my doctor?
You sure can! We’ll email you the moment your lab results are ready. You can access them in our secure online portal – download or print your results and bring them to your doctor’s office. Or simply upload the digital version during your telemedicine appointment.
How will my doctor know my empowerDX results are legit?
Not to worry. Our clinical labs are CLIA certified and CAP accredited, which means that the FDA and CDC ensure that our tests and practices are up to their rigorous standards.
Each test includes a “requisition” that is created and approved by our Licensed Ordering Physician Network. Our medical advisory team is comprised of experts who carefully design our processes & test results to be accepted by the greater medical community.
Before they’re publicly available, every biomarker undergoes an extensive validation at the lab to make sure that the test is both accurate and precise. However, the At Home COVID-19 Nasal PCR Test Kit is unique to this process –the FDA required an Emergency Use Authorization (EUA) to fast track its availability in the US. The FDA signed off on our Nasal PCR validation study proposal, results and intended use for the duration of the pandemic.
