Should we take vitamin D supplementation to fight COVID-19?
SPC has often spoken about the benefits of Vitamin D supplementation as we tend to have limited daylight during winter months in the UK.
Vitamin D deficiency is more common in older people, in people who are overweight, and in black and Asian people – all of the groups who are at increased risk of becoming very ill with Covid.
UK residents are already advised to consider taking supplements over winter when vitamin D levels can dip.
That is to improve general health, not specifically to stop infections.
Is there the research to back up Vitamin D and Covid prevention?
The trial, led by researchers from Queen Mary University of London and funded by Barts Charity, will use higher doses of vitamin D than regular supplements.
Principal investigator David Jolliffe said the trial “has the potential to give a definitive answer” to the question of whether vitamin D offers protection against Covid.
“Vitamin D supplements are low in cost, low in risk and widely accessible; if proven effective, they could significantly aid in our global fight against the virus,” he said.
Although vitamin D supplements are very safe, taking more than the recommended amount every day can be dangerous in the long run.
What about current research?
The Lancet has even gone further to say;
“Pending results of such trials, it would seem uncontroversial to enthusiastically promote efforts to achieve reference nutrient intakes of vitamin D, which range from 400 IU/day in the UK to 600–800 IU/day in the USA. These are predicated on benefits of vitamin D for bone and muscle health, but there is a chance that their implementation might also reduce the impact of COVID-19 in populations where vitamin D deficiency is prevalent; there is nothing to lose from their implementation, and potentially much to gain.
