The Claim

Daily supplementation with 1 gram of nano magnesium chloride for two weeks in adults with nonclinical insomnia symptoms significantly reduced self-reported tension and anger and improved overall mood as measured by the POMS subscales, with statistically significant differences (p ≤ 0.05) compared to baseline or control.

Cause and effect
1 study reviewed
In plain English

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.

See the scientific wording

In adults with nonclinical insomnia symptoms, daily supplementation with 1 gram of nano magnesium chloride for two weeks significantly reduced self-reported tension (POMS tension subscale: 3.04 vs. 1.42 points improvement, p=0.05) and anger (1.86 vs. 0.50 points, p=0.01), and improved overall mood (POMS total: -7.55 vs. -3.61, p=0.05), indicating a modest but statistically significant mood-enhancing effect.

Why this might work

Magnesium enters the brain and blocks overactive stress signals in nerve cells, while boosting calming signals. This reduces the body's stress response, lowers stress hormone levels, and allows the brain to regulate emotions more effectively, leading to less tension and anger and a better overall mood.

  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 felt less tense, less angry, and generally in a better mood compared to when they took a fake pill. The results suggest magnesium might help improve mood in people with mild sleep issues.
