Immunity Booster Vitamin D

Are you deprived of Vitamin D due to Lockdown?

Vitamin D is a nutrient as well as a hormone which is made by the skin on exposure to sunlight. It is well known for the absorption of calcium, magnesium, and phosphate.

Across the globe, the researchers are analyzing the patient data from various countries, however, the comparison is difficult due to varying factors affecting the respective countries. The scientists are trying to identify the association

between low average levels of vitamin D, and high numbers of COVID-19 cases and mortality rates.

Recent studies have shown low levels of vitamin D are associated with other non-communicable diseases and increased susceptibility to infectious diseases; in particular, upper respiratory tract infections.

Significance of vitamin D

Vitamin D-dependent antimicrobial pathways are known to respond to double-stranded RNA, which is easily produced during viral replication of SARS-CoV-2.

It supports the production of antimicrobial peptides in the respiratory epithelium, thus making the viral infection and development of COVID-19 symptoms less likely. Thus, reducing the inflammatory response to infection with coronavirus.

According to the Lancet “Vitamin D might help to reduce the inflammatory response to infection with Sars-CoV-2. Deregulation of this response is characteristic of COVID-19 and the degree of hyperactivation is associated with a poorer prognosis.”

Vitamin D Supplementation

Levels of the vitamin in the body can also be supplemented through a nutritionally balanced diet including foods that provide the vitamin, such as oily fish, red meat, egg yolk and fortified foods such as breakfast cereals, and safe sunlight exposure to boost vitamin D status.

Vitamin D supplements are widely available from supermarkets and chemists. They may be just vitamin D or part of a multivitamin tablet or even in solution form. The new ready to drink shots have shown better bioavailability, rapid absorption and are convenient than other forms of supplements.


Conclusions and Recommendations

Low vitamin D levels is common and may contribute to increased risk of respiratory infections including Covid-19. Thus, it is recommended that the affected population like the elderly, and other vulnerable people with underlying diseases should be urgently supplemented to enhance the resistance to Covid-19 and all the general adult population should also be advised to fulfill the daily requirement of vitamin D.

Many people may not be able to obtain the minimum amount of vitamin D due to various reasons, thus, consult your healthcare physician for the right supplementation.

Correcting a deficiency is simple, affordable and can have immense health benefits with a strong immune system.
