Daily supplements of magnesium may improve lung function in
asthmatics, and improve their quality of life, says a new study from
Measures of lung capacity increased by about 6 per cent during six
months of magnesium supplementation, and improvements were also
observed in the bronchial response to methacholine, a chemical that
produces constriction of the lungs, according to findings published in
the Journal of Asthma.
"Although there is conflicting research regarding magnesium
supplementation and asthma outcomes, this study adds to the body of
research that shows a beneficial response to magnesium supplementation
in people who have mild to moderate asthma," wrote researchers, led by
Alexandra Kazaks from Bastyr University in Kenmore, Washington State.
According to the European Federation of Allergy and Airway Diseases
Patients Association (EFA), over 30m Europeans suffer from asthma,
costing Europe €17.7bn every year. The cost due to lost productivity
is estimated to be around €9.8bn.
Epidemiological studies have reported beneficial effects of magnesium
on asthma occurrence and management, but less than half of adults in
the US consume the recommended levels of the mineral, according to the
National Health and Nutrition Examination Survey (NHANES) for
In order to test the hypothesis that magnesium supplements could
improve lung function, Dr Kazaks and her co-workers recruited 55 mild-
to-moderate asthmatics aged between 21 and 55 to participate in their
randomized placebo-controlled, double-blind trial. The participants
were randomly assigned to receive either the a daily dose of 340
milligrams of magnesium or placebo for 6.5 months.
At the end of the study, a 6 per cent improvement in lung function,
measured as the peak expiratory flow rate (PEFR), was observed in the
magnesium group, and not in the placebo group.
