what is magnesium for

Magnesium is a mineral that is crucial to the bodys function. It plays many important roles in the body, such as supporting muscle and nerve function, energy production, and regulating blood pressure and blood sugar levels. Magnesium is also important for maintaining bone health and protecting against bone loss. Low magnesium levels usually don't cause symptoms, but chronically low levels can increase the risk of high blood pressure, heart disease, type 2 diabetes, and osteoporosis. Fortunately, magnesium is found naturally in many foods, including nuts, seeds, whole grains, beans, leafy vegetables, milk, yogurt, and fortified foods. Just a few servings of magnesium-rich foods a day can meet your need for this important nutrient. Magnesium supplements are also available, but high doses of magnesium from supplements or medications can cause nausea, abdominal cramping, and diarrhea.
