Does vitamin D help with asthma? More study needed

By Janice Neumann NEW YORK (Reuters Health) - Asthma sufferers who received vitamin D supplements for six months, in addition to their regular inhalers, could breathe a little easier than those who relied only on the inhalers, in a recent study in Iran. The researchers say the results - if confirmed by larger studies - might help the many people who sometimes have troublesome asthma symptoms even though they use medication. “It does build some on the growing amount of data that shows vitamin D might help those affected by asthma,” Dr. Mario Castro, who was not involved in the study, told Reuters Health. “Given that vitamin D is a relatively benign supplement,” the small improvement in lung function “would be worthwhile if it was confirmed with other improvements in asthma control,” he said, such as fewer symptoms or a reduced need for medication.
