The Study
Effectiveness of Magnesium Supplementation on Sleep Quality and Mood for Adults with Poor Sleep Quality: A Randomized Double-Blind Placebo-Controlled Crossover Pilot Trial
This study tried giving people magnesium pills and saw if they slept better and felt happier. It’s like a fair test where neither the participants nor the researchers knew who got the real pills or fake ones. It found some improvements, but because only 31 people were tested, we can’t say for sure it works for everyone.
Analysis score
Maximum 45 for a randomized controlled trial.
Where the score came from
People who took a daily magnesium pill before bed for two weeks slept a little longer, had less trouble staying asleep, and felt less tense and angry compared to when they took a sugar pill.

Taking magnesium supplements leads to better sleep quality through changes in neurotransmitter activity and reduced nervous system activity.
In adults with mild sleep problems, taking 1 gram of nano magnesium chloride daily for two weeks resulted in a measurable improvement in sleep quality and an increase in total sleep time compared to a placebo.
In adults with mild sleep issues, taking 1 gram of nano magnesium chloride daily for two weeks resulted in lower reported levels of tension and anger and improved overall mood, with statistically significant changes on standardized mood scales.
In adults with mild sleep trouble, taking 1 gram of nano magnesium chloride daily for two weeks increases the amount of deep sleep and improves readiness scores based on heart rate variability, sleep quality, and daily activity balance.
In adults with mild sleep trouble, taking 1 gram of nano magnesium chloride daily for two weeks increased sleep efficiency and reduced nighttime wakefulness compared to a placebo.
In adults with mild sleep trouble, taking 1 gram of nano magnesium chloride daily for two weeks did not cause any side effects and everyone took it as directed.
