Adequate magnesium intake may support heart health in heart attack survivors, researchers say

Researchers examined the magnesium intake of 4,365 patients over 12 years (including follow-up) and found an inverse relationship between mineral levels and CVD mortality.

A high magnesium intake of 322 mg daily was associated with a lower risk of CVD and total mortality, and especially among participants taking diuretics.

Based on current results and previous evidence, the authors suggest that magnesium intake may be more strongly associated with mortality risk in CVD patients than in the general population.

“Our findings highlight the importance of adequate magnesium intake in patients with cardiovascular disease, in addition to treatment with cardiovascular medications.” ​write the researchers in Frontiers in Cardiovascular Medicine.

“The highest risk of CVD mortality was observed at below-average magnesium intakes. Estimates of protective risk for CVD mortality are shown for magnesium intakes above adequate intakes.

Different requirements

The findings add to an ever-growing body of science supporting the mineral’s potential health benefits. The National Institutes of Health (NIH) lists magnesium as necessary for more than 300 biochemical reactions in the body, from helping maintain normal muscle and nerve function to maintaining a steady heart rate, maintaining a healthy immune system, and maintaining healthy bones. The mineral is also needed for blood sugar management and healthy blood pressure.

European experts recommend a daily magnesium intake of 350 mg for men and 300 mg for women, as adequate levels can help control blood sugar levels, blood pressure and myocardial metabolism.
