Vitamin-D Deficiency May Lead To COVID-19

COVID-19 and Vitamin-D

COVID-19 is spreading again across the world. Furthermore, people with vitamin-D deficiency are more likely to develop COVID-19 infection. The majority of the world population has low levels of vitamin-D. Additionally, nutrition deficiency leads to various diseases. Vitamins are an essential part of the human body. Moreover, the shortage of any vitamin can result in lethal consequences. 

Vitamin – D

Vitamin D is an essential micronutrient that performs multiple functions in the body. Furthermore, it acts as a vitamin, hormone, and immunomodulatory. Moreover, the action of vitamin D in the immune system is vital. The vitamin is present in most immune-cells. Furthermore, the immune system needs adequate levels of vitamin D to fight against invading pathogens rapidly. 

Vitamin-D performs immunosuppressants, anti-inflammatory, anti-bacterial, and anti-viral actions. Its deficiency can cause COVID-19 infection. There are two types of vitamin D. These are Ergocalciferol-D2 and Cholecalciferol-D3. Both types are fat-soluble. Adults need 2000 IU to 3000 IU per day, while children need 1000 IU per day. Doses above 4000 IU are beneficial in the longer run.

Vitamin-D’s role in the regulation of calcium-phosphate homeostasis is well-known. Furthermore, this vitamin is essential for bone formation. Thus, its levels affect skeletal health during growth and in adult age. The lack of Vitamin-D is known to cause rickets in children and osteoporosis in older people. 

Health professionals linked the deficiency of the vitamin to high levels of three substances in lab tests. Moreover, these tests include serum ferritin, troponin, and D-dimer. The presence of biomarkers at a high level in blood indicates infection and inflammation in the body.

Vitamin-D and COVID-19

According to researchers from Spain, coronavirus patients have a deficiency of vitamin-D. The researchers published their findings in the Journal of Clinical Endocrinology and Metabolism. Furthermore, 216 COVID-19- hospitalized patients were part of the study. Moreover, 80% of these patients have Vitamin-D deficiency. 

For the retrospective study, researchers set 197 controls from the general population. Labs determine the level of vitamin D by measuring levels of 25-hydroxyvitamin D or 25(OH)D. The deficiency cutoff levels for 25(OH)D for the study were in a range of 25 ng/mL to 20.9 ng/mL. 

According to the research, men have more vitamin D deficiency than women. Men with Vitamin-D deficiency and coronavirus infection experience more severity and mortality than women. 

Moreover, Covid-19 patients with vitamin D deficiency have longer stay in the hospital. Furthermore, such patients have a high prevalence of hypertension and cardiovascular diseases. Harvard is researching the link and effect of vitamin D on coronavirus. Moreover, research on the mechanism of action by which vitamin D affects COVID-19 is in progress.

Vitamin D Deficiency Correction

Vitamin-D deficiency is curable. However, people are not sure about the amount of vitamin D that they must intake daily. Some people say that you recover from a shortage of vitamin D with time, but it is not correct. Moreover, you must take proper Vitamin D supplements in the form of tablets, capsules, etc. Furthermore, you must take these supplements to raise your body level of 25(OH)D.

Furthermore, people with deficiency must take Vitamin D rich foods in their diet. Some foods rich in this vitamin are fatty fish, egg yolk, liver, and certain types of UV-irradiated mushrooms. Moreover, cereal, milk, and orange juice provide a small quantity of the vitamin. 

Furthermore, a small quantity is not sufficient for COVID-19 patients. A minute-quantity, like 100 IU per eight-ounce cup of milk, is only useful in preventing gross Vitamin-D deficiency. However, such a minute-quantity is not enough to eradicate the shortage of vitamin D.

Correcting deficiencies with supplements is necessary. Vitamin D3 supplements are available in various dosage forms and dose regimens. Furthermore, after consulting a doctor, you can start taking any of these supplements with a suitable dose.
