In general, magnesium is considered to be healthy and essential for maintaining good health. However, it is important to consume the recommended daily amount of magnesium, as getting too little or too much can have negative effects on health. The recommended daily intake of magnesium varies depending on age, sex, and life stage, but most adults should aim to consume between 310 and 420 milligrams per day. It is generally easy to get enough magnesium from a healthy diet that includes a variety of whole foods, such as leafy green vegetables, nuts, seeds, and whole grains. However, some people may need to take a magnesium supplement if they are at risk of deficiency, such as those with certain medical conditions or those who have had gastrointestinal surgery.
