A new study titled "Vitamin D Deficiency Linked to Poor Lung Function in Adults With Bronchiectasis" was just posted on "Bronchiectasis News Today". Results revealed that the average levels of 25-hydroxyvitamin D or 25(OH)D — the major form of vitamin D in the blood — were significantly lower in adults with bronchiectasis than in healthy individuals, 14.7 vs. 19.8 nanograms (ng)/mL. In addition, nearly three quarters (73.1%) of the patients with bronchiectasis had vitamin D deficiency, with 25(OH)D levels under 20 ng/mL.
Bottom line from the study was, vitamin D deficiency was common in adult bronchiectasis patients and it might be related to severe radiological findings on chest [CT] and poor lung functions,” the researchers wrote.
I would suggest anyone with Bronchiectasis get their blood level checked before taking any supplements. Bill
