The Connection between Vitamin D and Covid 19

More and more studies show a significant connection between vitamin D and COVID-19. A research group that recently examined 216 people with Sars-Cov-2 found that 80 percent of those affected did not have enough vitamin D in their blood. According to the study, vitamin D deficiency can be a decisive factor influencing the disease’s course and severity.  As part of this study, published in the Journal of Clinical Endocrinology & Metabolism, researchers examined 216 COVID-19 patients in a Spain hospital.

The study results at a glance:

-80 percent of those affected by Covid-19 did not have enough vitamin D in their blood

-Men had lower levels of vitamin D compared to women.

-Those affected with low vitamin D had higher inflammation markers such as ferritin and D-dimer in their bodies. These elevated levels have been linked to a prolonged and more difficult recovery with Sars-Cov-2.

-Hospital stays due to COVID-19 were longer than for people with adequate vitamin D levels.

-People with vitamin D deficiency had a higher prevalence of high blood pressure and cardiovascular disease.

Vitamin D is crucial for stimulation of intestine

“It looks like patients with poor vitamin D status could have more severe COVID-19,” stated Dr. Hans Konrad Biesalski, professor at the University of Hohenheim, Germany in “Healthline.” He evaluated vitamin D and COVID-19.  Here is his explanation for vitamin D level problems: “The most important vitamin D source is through the formation of sunlight in the skin, which seems to works less with an increased age.”

Also, both the elderly and the chronically ill often spend less time outdoors and cannot get enough sun. People tested with low vitamin D levels tend to be older or more likely to have previous illnesses than people with normal vitamin D levels. Over 60 years of age, a reduction in the synthesis of vitamin D in the skin becomes apparent. This may be the main reason they get sicker with a Sars CoV-2 infection.

“An additional intake of vitamin D is particularly recommended for people with a previous illness or older adults,” said the doctor. Vitamin D levels are often devastatingly low in people in nursing homes. But people in home offices or people who stay longer in closed rooms and rarely go outside can also have an inadequate vitamin D supply.

Vitamin D deficiency increases Covid-19 mortality 19-fold

One study concluded that COVID-19 patients who received a high enough vitamin D dose had a 51.5 percent lower risk of dying from the disease and a significantly reduced risk of complications.

Another new study found the same thing – it found that more than 80 percent of people with COVID-19 did not have adequate amounts of the “sunshine vitamin” in their blood. The risk of a fatal outcome was 19-fold increased with vitamin D deficiency compared to normal vitamin D levels.

 Vitamin D is recommended for the prevention of respiratory diseases. COVID-19 is an acute respiratory disease. Studies have shown that vitamin D supplementation reduces critical respiratory disease risk in people with low vitamin D levels by up to 70 percent. 

Dr. José L. Hernández from the University of Cantabria and co-author of one of the studies, said, “Identify (test) and treat vitamin D deficiency especially in high-risk groups as the elderly, chronic patients and nursing home residents.  Those are the primary target for COVID-19,”

 People who are at high risk for COVID-19 can take vitamin D.
“Supplementation of Vitamin D should be recommended to COVID-19 patients who have low levels of vitamin D in the blood, as this approach could have beneficial effects on both the musculoskeletal system and the immune system,” said Hernández in an explanation.
