Magnesium is known as an ultimate relaxation mineral. Healthy levels of magnesium calm the nerves, promote good sleep and good mood, and bring anxiety and depression levels several notches down. In simple words, magnesium equips our nervous system to respond to stress better. Magnesium deficiency has been associated with a wide range of stressful conditions – jingled nerves, migraine, chronic fatigue syndrome, fibromyalgia, audio-genic stress, depression, anxiety and poor sleep.
