These data agree with the notion of salt-sensitive hypertension necessarily results from a higher bioavailability: either level of cooking water also intervenes in the Mg intake. Consequently water Mg intake may intervene in cardiovascular Benefits of drinking bottled water high in magnesium: Many studies show that water high in magnesium is related to decreased risks for cardiovascular disease, especially for sudden death from cardiovascular disease.

Case in point – we have, in fact, known for years that the addition of magnesium to the municipal water supply (drinking water) has not only yielded significant health benefits, but also that the softening of water – and, therefore, depleting of minerals – is detrimental overall in regards to public health.
