The Claim

Daily supplementation with 1 gram of nano magnesium chloride for two weeks significantly improved self-reported sleep quality (as measured by Pittsburgh Sleep Quality Index reduction of 2.68 points) and increased objective sleep duration by an average of 3.7 minutes per night compared to placebo in adults with nonclinical insomnia symptoms (mean age 46, n=31).

In plain English

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.

See the scientific wording

In adults with nonclinical insomnia symptoms (mean age 46, n=31), daily supplementation with 1 gram of nano magnesium chloride for two weeks significantly improved self-reported sleep quality (Pittsburgh Sleep Quality Index reduction of 2.68 points vs. 1.74 in placebo, p=0.05) and increased objective sleep duration by an average of 3.7 minutes per night compared to placebo, suggesting magnesium may modestly enhance sleep quality in this population.

Why this might work

Magnesium enters the brain and blocks overactive brain signals by calming excitatory receptors, while boosting calming signals. This reduces stress hormone levels, which quiets the nervous system at night, allowing deeper and longer sleep.

  1. 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 found that adults with mild sleep problems who took a daily magnesium supplement for two weeks slept a little better and got about 4 more minutes of sleep each night than those who took a fake pill.
