For many asthma sufferers, relief comes from nutrition. In addition to vitamins and mineral supplements that repair tissues and boost immunity, many physicians recommend bioflavonids, quercetin, bromelin and coenzyme Q10, all of which may help reduce the frequency and severity of asthma attacks. Vitamins A, B complex, C and E are considered most important, along with magnesium, selenium, and beta carotene.
In fact, vitamin C may be more significant than previously realized.
In 1995 The American Journal of Clinical Nutrition published a report showing that a diet low in vitamin C is a risk factor for asthma, particularly in environments containing tobacco smoke and similar oxidants. According to this article, 7 of 11 studies on vitamin C have shown significant improvement in respiratory measurement within two hours after the patients took 1 to 2 grams of vitamin C. These studies are the first to show such a positive correlation and the first to use large doses of the vitamin. Previous trials using 500 mg or less were less conclusive.
Vitamin C has been shown to have antihistamine properties; it inhibits experimentally induced bronchial constriction in normal and asthmatic subjects, and in double-blind controlled studies, doses of 1 gram per day have been shown to be an effective, though not curative, preventive measure for some patients with bronchial asthma.
