Magnesium

"Magnesium is a nutrient that the body needs to stay healthy. Magnesium is important for many processes in the body, including regulating muscle and nerve function, blood sugar levels, blood pressure and making protein, bone, and DNA. The amount of magnesium you need depends on your age and sex. Magnesium is essential for the electrical activity of nerves and muscle, and is indicated to relieve painful cramps (including menstrual cramps), twitching and tremors. Magnesium is important for healthy bones. People with higher intakes of magnesium have a higher bone mineral density, which is important in reducing the risk of bone fractures and osteoporosis."
