Effects of Magnesium Breakthrough on Sleep Quality and Mood in Women With Poor Sleep: A Randomized, Double-Blind, Placebo-Controlled Crossover Trial
Jacksonville University
Summary
This study will test whether a magnesium supplement (Magnesium Breakthrough) improves sleep quality and mood in women ages 35 to 60 who have poor sleep but no diagnosed sleep disorder. Participants will take the magnesium supplement for two weeks and a matched placebo for two weeks, in random order, separated by a one-week washout period. Neither participants nor study staff will know which product is being taken during each period. Throughout the study, participants will wear an Oura Ring to track sleep patterns and will complete short daily and biweekly questionnaires about their sleep, mood, stress, and energy levels. The main measure of interest is change in sleep quality, assessed using a validated sleep questionnaire (the Pittsburgh Sleep Quality Index). The study will also look at effects on mood, stress, and objective sleep measures from the Oura Ring. All study activities - screening, consent, and data collection - are conducted remotely, so participants can take part from anywhere in the United States.
Description
Poor sleep quality affects a substantial proportion of adults, and women are disproportionately affected, particularly during the perimenopausal and postmenopausal transition. While Cognitive Behavioral Therapy for Insomnia (CBT-I) remains the gold-standard non-pharmacological treatment, access is limited. Pharmacological options such as benzodiazepines and common sleep aids carry risks of dependence, tolerance, and next-day cognitive impairment, while their objective sleep benefits are often modest. This has fueled interest in nutritional approaches to sleep support. Magnesium is an essentia…
