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.
People who have trouble sleeping may want to use magnesium supplements to help. The right dose may fall between 200 and 400 mg/day.
