"If I had to recommend one nutrient for people with asthma, it would be magnesium," says Dr.Firshein. The mineral act as a natural bronchodilator, meaning that it relaxes and opens the bronchial tract, the airway to the lungs that becomes contricted during asthma attacks. He recommands taking a daily 500-milligram supplement of either magnesium aspartate or magnesium citrate. You can take this supplement every day for 6 months, he suggests.
