Vitamin D and COVID-19

Food Sources of Vitamin D

In a pandemic, with a stay at home mandate, there is little you are able to control. However, self-care and diet are one aspect that you do have control over. What you and your child eat can contribute to how your immune system responds to COVID-19. Of particular interest, is the link between vitamin D and respiratory illness. Studies are linking individuals with vitamin deficiencies with more severe cases of COVID-19 and higher mortality rates.  Vitamin D plays an important role in immune function, including fighting diseases.  It has been linked to severity of respiratory infections in the past such as influenza. 

Here are a few ways to naturally increase vitamin D intake:

Vitamin D from the Sun
  • Eat fish. It is found in fatty fish such as salmon and tuna. Eating six ounces of salmon gives you approximately 4,000 IU of vitamin D.
  • Go swimming. Vitamin D can be absorbed by the sun. However, to make enough, you need 15 minutes of sun exposure with no sunscreen and with lots of skin exposed such as wearing a swimsuit. Location and skin type can also affect absorption of vitamin D by the sun. 
  • Eat eggs. Vitamin D is found in egg yolks and can be enhanced by eating eggs from chickens that have been pasture raised. Why is pasture raised important? The chickens absorb sunlight when they are in the pasture, which adds more vitamin D to their eggs.
  • Read about it. Dr. Michael Holick, is a leading authority and researcher on vitamin D, he recommends 2,000 IU a day for adults and 1,000 IU for children. His book, The Vitamin D Solution, offers inexpensive, easy ideas to reverse vitamin D deficiency.

Science tells us vitamin D can reduce the symptoms of infectious diseases such as influenza and COVID-19. It plays an important role in bone and mental health as well. Enhancing intake is easily done with diet and sun exposure. However, it doesn’t hurt to supplement it, especially during a pandemic. When buying supplements make sure you buy from a quality source such as your chiropractor or O’Briens Pharmacy.
