Vitamin B6 deficiency is com in asthmatics.24 This deficiency supplements may relate to the asthma itself or to certain asthma drugs (such as theophylline and aminophylline) that deplete vitamin B6. supplements Double-blind research shows that fish oil partially reduces reactions to allergens that can trigger attacks in some asthmatics.55 antioxidants and Another double-blind study sho that fish oil supplements prevented exercise-induced asthma attacks in people with asthma. Some researchers antioxidant nutrients have suggested that asthma attacks triggered by exercise might be caused by free-radical vitamins and minerals damage caused by the exercise. Some doctors are currently experimenting with 400 to 1,000 mg of quercetin three times per day. Bromelain reduces the thickness of mucus, which may be beneficial for those with asthma,70 though clinical actions in asthmatics remain unproven. Lycopene, an antioxidant related to beta-carotene and found in tomatoes, helps reduce vitamin shop the symptoms of asthma caused by exercising. In one double-blind trial,23 over half of people with exercise-induced asthma antioxidant nutrients had significantly fewer asthma symptoms after taking capsules containing 30 mg of lycopene per day for one week compared to when they took a placebo. Magnesium levels are frequently low in asthmatics.29 Current evidence suggests that high dietary magnesium intake may be associated with better lung function and reduced bronchial reactivity. Quercetin, a flavonoid found in most plants, has an inhibiting action on lipoxygenase, an enzyme that contributes to problems with asthma.69 No clinical trials in humans have confirmed whether quercetin decreases asthma symptoms. Pycnogenol is a proprietary mixture of flavonoids extracted from the bark of a French maritime pine tree. Asthma involves free-radical damage that selenium might protect against. In a double-blind trial, supplementing with pycnogenol significantly improved lung function and asthma symptoms and significantly reduced the need for rescue medication in a group of children (ages 6 to 18 years) with asthma. People with low levels of selenium have a high risk of asthma. Beta-carotene is an antioxidant that protects against free-radical damage.. In a small double-blind trial, supplementation with 100 mcg of sodium selenite (a form of selenium) per day for 14 weeks resulted in clinical improvement in six of eleven patients.
