Magnesium is an essential mineral for overall health as it plays a widespread role in your body. It is a vital nutrient for proper muscle function, as it controls their contractions, helps in relaxing them and in reducing muscle spasms and tightness. Moreover, magnesium plays a crucial part in regulating the production of melatonin, which guides your body’s bio clock. So, having adequate amounts of magnesium can improve sleep quality, especially in people who exercise and need to keep their muscles relaxed and flexible.
