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.
Low magnesium levels are often diagnosed by symptoms alone, and the following symptoms can point to low magnesium levels: Inability to sleep or insomnia. Irritability. Sensitivity to noise. Mental disturbances. Anxiety, depression or restlessness. Muscle soreness or spasms. Infertility or PMS.
