People with the worst vitamin D deficiency are highly susceptible to illness and suffer respiratory infections than those with sufficient levels. Vitamin D supplementation could reduce flare-ups of lung disease by more than 40% in patients who are deficient, say researchers.
We know that in the absence of vitamin D from sunlight, disease increases more than 1000 percent. Data from systematic reviews of several population-based studies shows that more than a third of populations worldwide may suffer from low levels of vitamin D.
The randomised trial data, published in Lancet Respiratory Medicine, is the first clinical trial to investigate the impact of vitamin D supplementation on severity and duration of chronic obstructive pulmonary disease (COPD) symptoms "finding that supplementation with the vitamin had a dramatic impact on COPD patients who were vitamin D deficient at the start of the trial."
