A study out of England found that vitamin D supplementation reduced chronic obstructive pulmonary disease symptoms by forty percent in patients who were previously deficient in that vitamin. The symptoms of this disease include coughing, overabundance of mucus, shortness of breath and tightness of chest. These problems have the potential to worsen and lead to hospitalization. All patients who supplemented with vitamin D saw a modest reduction in their flare ups, but those patients who were not vitamin D deficient did not see the dramatic forty-percent reduction.
This is the first clinical trial to investigate the impact of vitamin D supplementation on severity and duration of COPD symptoms. One previous trial has linked vitamin D to a reduction in COPD disease flare ups but this was limited to patients with very severe conditions. This trial is larger and studied patients with a much broader spectrum of diseases, ranging from mild to severe.
Vitamin D deficiency is so widespread that it has been recognized as a pandemic, according to the American Journal of Nutrition. Two-thirds of US adults and children are thought to be deficient in this most necessary vitamin. Possible side effects from vitamin D may include greater risk of cardiovascular disease, cognitive impairment in older adults, severe asthma in children, cancer, diabetes 1 and 2, hypertension, glucose intolerance and multiple sclerosis: WEB MD.
