A new study from researchers at Trinity College Dublin said that vitamin D deficiency may be linked to higher death rates from COVID-19.
And that boosting the body with the common vitamin may be a game changer in the fight against the virus.
Published in the Irish Medical Journal, the report analyzed vitamin D levels of older people in countries heavily affected by the coronavirus.
The researchers found that places with high death rates from COVID-19, including Italy and Spain, also had rates of vitamin D deficiency.
Countries such as Norway, Finland and Sweden, although typically less sun-filled, actually showed lower rates of vitamin D deficiency as well as lower mortality rates from COVID-19.
The researchers suggest that “supplementation and fortification of foods” could be why vitamin D is at healthy levels there and that “optimizing” vitamin D levels elsewhere may prevent serious coronavirus complications.
