The present study is part of a project titled 'Magnesium in asthma and chronic obstructive pulmonary disease'. The hypothesis of the main project is that a daily magnesium supplement will benefit patients with asthma and chronic obstructive pulmonary disease.

The aim of this part of the project is to study the effect of a daily magnesium supplement for COPD-patients
