Sometime last year, when the pandemic had begun and people were still looking for solutions and ways to build up immunity to prevent getting infected from COVID-19, vitamin D emerged as an unlikely solution by many championing natural solutions to a virus which had brought the world to a halt.
Vitamin D promotes the human body’s ability to absorb calcium and is known to keep teeth and bones healthy. It’s also an important part of the human body’s immune system.
Now a new study done has found that the risk of testing positive for COVID-19 was higher for people of African origin, with lower vitamin D levels. This study was done on more than 4,000 people in Chicago and has been published in the medical journal JAMA Network Open.
Multiple studies have been done over the past year on the connection between Vitamin D levels and COVID-19, but experts maintain that these studies are inconclusive.
A small study of 129 COVID-19 patients in New York showed that Vitamin D supplements may prevent extreme downfall in health leading to death, or even ventilator dependency. The study is yet to be peer-reviewed and published. It was presented at the Endocrine Society’s annual meeting.
Currently, there is no formal guidance on the use of supplements, of vitamin D, zinc as a treatment for COVID-19 by the World Health Organisation. In February, a study done in Brazil showed that a high single dose of Vitamin D on hospitalised COVID-19 patients did not reduce the length of hospital stay.
It is also important to remember that the human body can only absorb so much Vitamin D before it becomes harmful for our health. While sun exposure remains the best way for the body to produce it, too much vitamin D raises calcium level in blood leading to nausea, weakness.
While some countries are testing therapeutic ways to treat COVID-19, currently vaccination, isolation and wearing a mask is the recommended way to prevent infection.
