As many of you may know, I have attempted to show the benefits of Vitamin D over about 5 years on this thread (General Health ).
Again, I am trying to bring your attention to some remarkable results, from VitD supplementation , as described in this research paper, in the BMJ ( British Medical Journal.)
www.bmj.com/content/bmj/356/bmj.i6583.full.pdf
This publication may be difficult to follow , so , you may want to watch this video by Dr. John Campbell , who clearly explains what it means, with reference to Covid-19 ( coronavirus) . Essentially ... if you have low levels of vitamin D , then you can markedly improve your chances of improving your immune response to it, in other words: Improve your chance of becoming less ill when infected.
Watch here ....
Dr Campbell is the Dr. that the coronavirus thread refers to here on Mumsnet. <a class="break-all" href="https://www.mumsnet.com/Talk/coronavirus/3843290-worried-about-coronavirus-covid19-part-18" target="_blank">www.mumsnet.com/Talk/coronavirus/3843290-worried-about-coronavirus-covid19-part-18</a>
You may also be interested in this series, Dr. Seheult , ( a pulmonologist). This clip is about VitD and coronavirus from 2.50 mins. A more in depth explanation.
I hope this information is of interest or useful for some.
Best of Luck,
BTBH.
