"Scientists Say This Supplement May Help Protect You From the Flu"
While there are plenty of natural ways to boost your immune system, new research points to a supplement that may help curb severe reactions to the flu: vitamin D.
That's the takeaway from new research published in The American Journal of Clinical Nutrition. For the study, researchers analyzed health data from 36,258 people who participated in the UK Biobank, a long-term biomedical research resource.
The researchers discovered that people with a severe vitamin D deficiency (measured as less than 15 nmol/L) had a 33% higher rate of being hospitalized for a respiratory tract infection compared to those who had vitamin D levels of 75 nmol/L or higher. For each 10 nmol/L increase in vitamin D, the hospitalization rate for respiratory tract infections dropped by 4%.
