Magnesium deficiency is often a precursor to sleep disorders, such as anxiety, hyperactivity and restlessness. Itâs been suggested that this is because magnesium is vital for GABA function, an inhibitory neurotransmitter known to âcalmâ the brain and promote relaxation.
Of course, it's not that easy to tell if you have a magnesium deficiency; the effects are mostly vague, stuff like hyperexcitability, muscle weakness, and sleepiness, as well as, um, fasciculations. So make sure to eat high-magnesium foods like leafy greens, nuts, and wheat bran.
