Now Magnesium Inositol Relax Powder is a dietary supplement with a formula that combines magnesium and inositol. Magnesium is a highly important mineral in the body, especially at the nervous level. It contributes to the reduction of tiredness and fatigue and normal psychological and nervous function because it participates in nerve impulses, the production of neurotransmitters, and other biochemical reactions important for maintaining cognitive functions, mood, and mental performance. Inositol is a nutrient associated with the B complex that has been shown to be useful for relaxation (studies show a decrease in the frequency of panic attacks), and its deficiency in the brain has been associated with nervous disorders such as depression.
