A study was conducted to evaluate the efficacy of Magnesium supplements to improve sleep quality of patients suffering from sleep disorders. 14 patients with sleep disorders took part to this experimental study. During a first period of one week, the quality of sleep of these patients was measured every night by a machine with sensors recording sleep phases, duration, breathing and movements. The machine outputs a score related to sleep quality, the higher the value, the higher the quality. Afterwards, for a second one week period, 8 of these patients were given daily Magnesium supplement tablets, while 6 were given daily Melatonin supplement tablets. Quality of sleep was measured again during this second period for both groups. The data are reported below.
