3. Sleeping troubles
If you aren’t getting enough magnesium, you may notice that you aren’t getting proper sleep. Also, magnesium supplements are often used to treat the symptoms of insomnia. GABA is a neurotransmitter that is needed for deep sleep and to help calm you down. Magnesium is needed to stimulate the production of GABA, so a deficiency in magnesium will result in restlessness, insomnia, and disturbed sleep.
