As Covid-19 cases continue to rise, many are searching for ways to protect themselves from the virus.
Vitamin D is an important hormone! It is absorbed through the skin directly from the sun, or can be taken through supplements and diet (1).
Research has shown that there is a connection between Vitamin D and the immune system. In the past, research has found that Vitamin D is an important regulator of the immune system. Vitamin D deficiency has been linked to increased chances of immune related diseases, infections and cancer (2).
Recently more research has been conducted to examine the relationship between Vitamin D and Covid-19. Several studies have found that Vitamin D plays a major role when it comes to Covid-19. It may just be the way to prevent and fight Covid-19!
What is the Relationship Between Covid-19 and Vitamin D?
A recent study was conducted to examine the relationship between patients hospitalized with Covid-19 and their Vitamin D levels. 75% of the people hospitalized had Vitamin D deficiency. Also, 85% of those patients required ICU care.
In addition, a study was conducted in Europe, where Vitamin D deficiency is common in northern countries, especially during the winter months. This study found that those who had higher rates of Vitamin D deficiency were more likely to be infected and die from Covid-19 (3).
A third study was conducted over a 6 week period. It examined 2 groups of patients. One group was positive with Covid-19 and asymptomatic. The other group was positive for Covid-19 and severely ill in the ICU. The study found that the second group that was in the ICU were more likely to have Vitamin D deficiency. The death rate was much higher for those who were Vitamin D deficient as well.
How Does Vitamin D Help Fight Against Covid-19?
You may be wondering what the relationship is between Vitamin D and Covid-19. Well, Vitamin D can promote antiviral immunity in the body. It can block viral entry and slow down viral replication. Vitamin D also promotes autophagy. Autophagy is the the body’s way of cleaning out damaged cells, in order to regenerate newer, healthier cells. As you can see, Vitamin D plays a key role in helping your body fight against viruses (4).
Covid-19 is a virus known for attacking the lungs. The respiratory tract is a very large surface in the body. This makes it a suitable environment for pathogens like Covid-19 to live on (4). Research has shown that people with Vitamin D deficiency are more likely to develop respiratory tract infections (3). Vitamin D deficiency can also lead to pneumonia. The antiviral response by Vitamin D can help fight against respiratory tract infections (4).
How Can I Maintain a Healthy Level of Vitamin D?
It can be difficult for many of us to maintain a healthy level of Vitamin D in the body, especially those who live in northern countries and deal with winter weather. I personally discovered that I was quite deficient in Vitamin D a few years ago. I wasn’t absorbing enough naturally through the sun’s UVB rays. I started taking Vitamin D supplements and I am glad I did! We have provided our top recommendations to increase you Vitamin D levels below.
