This one, hailing from Italy, found that taking a combination of melatonin, magnesium and zinc led to considerably improved sleep quality. In the study, 22 participants with primary insomnia were given the supplement (5mg melatonin, 225mg magnesium and 11.25mg zinc mixed with 100g of pear pulp) one hour before bedtime every night for eight weeks. 21 participants were given a placebo of just the pear pulp.
Those who took the supplement saw improved sleep quality, found it easier to get to sleep, woke up feeling more refreshed and alert and slept for longer.
This certainly sounds encouraging - but don't go starting a new insomnia treatment regime based on this study alone. Always speak with your doctor first.
