Vitamin D supplementation during the COVID-19 pandemic has proven to be useless as a method of preventing respiratory infection or SARS-CoV-2.
This conclusion was made by scientists at Queen Mary University of London and other scientific organizations in the UK, who published the results of a clinical study in the British Medical Journal.
The randomized controlled trial involved 6,200 people over the age of 16 who did not initially take vitamin D supplements.
During the study, which lasted six months, one group of volunteers with initially low levels of vitamin D in the blood took 800 international units (IU) of vitamin D daily, the second group – 3200 IU. The rest took a placebo. The subjects were given a blood test to check the level of calcifediol, a form of vitamin D produced in the liver.
