The mineral getting most of the attention is calcium, but all of the minerals are important, especially magnesium. The reviewed research investigated the importance of magnesium as it relates to cardiovascular health (Zhang W, et al. 2012). The participants were 58,615 healthy Japanese aged 40-79 years and the average follow up time was 14.7 years. Dietary magnesium intake was inversely associated with mortality from hemorrhagic stroke in men and with mortality from total and ischemic strokes, coronary heart disease, heart failure and total cardiovascular disease in women. When adjustments for calcium and potassium intake were accounted for the association were reduced, but the researchers still concluded that dietary magnesium intake was associated with reduced mortality from cardiovascular disease especially for women. This means that if you are going to take a mineral supplement, you are better off not only taking calcium, but should also include other important minerals. There are also other reasons why that is beneficial, you can read more about that by clicking here.
