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.

Despite feeling like youâre always tired, low magnesium levels and high potassium can cause trouble getting good rest because of ongoing pains and mental disturbances.
