Research is showing that Vitamin D may reduce the severity of COVID-19. The following is a recent excerpt from a peer-reviewed study done at the College of Physicians:
“The severity of COVID-19 is determined by the presence of pneumonia, severe acute respiratory distress syndrome, myocarditis, microvascular thrombosis and/or cytokine storms, all of which involve underlying inflammation.
A principal defence against uncontrolled inflammation, and against viral infection in general, is provided by T regulatory lymphocytes (Tregs). Treg levels have been reported to be low in many COVID-19 patients and can be increased by vitamin D supplementation.
Low vitamin D levels have been associated with an increase in inflammatory cytokines and a significantly increased risk of pneumonia and viral upper respiratory tract infections.
Vitamin D deficiency is associated with an increase in thrombotic episodes, which are frequently observed in COVID-19.
Vitamin D deficiency has been found to occur more frequently in patients with obesity and diabetes. These conditions are reported to carry a higher mortality in COVID-19.” *
This is only one of many studies of its kind!
Pandemic aside, Vitamin D is also very important for:
promoting healthy bones and teeth.
supporting immune, brain, and nervous system health.
regulating insulin levels and supporting diabetes management.
Anyone living with an autoimmune condition.
supporting lung function and cardiovascular health.
Approximately 30% of Canadians are Vitamin D deficient (even higher in the winter). Some studies have shown that number to have gone higher during the pandemic given how many people stayed indoors more than usual (= less sun exposure).
As we head into winter/cold/flu season – you should know that Vitamin D supplements protect against acute respiratory infections including colds and flu – and may also help combat symptoms of Seasonal Affective Disorder (SAD).
Vitamin D is a fat-soluble vitamin and can “build up” in your system – so always take with food, and do speak with your healthcare practitioner about how to safely supplement with Vitamin D.
