Adequate magnesium intake can support heart health for heart attack survivors, researchers say

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

A high magnesium intake of 322 mg per day was linked with a lower risk of CVD and all-cause mortality, and particularly among participants taking diuretics.

Based on current findings and previous evidence, the authors suggest that magnesium intake may be more strongly related to mortality risk in patients with cardiovascular disease than in the general population.

“Our findings underscore the importance of adequate magnesium intake in patients with cardiovascular disease, in addition to cardiovascular drug treatment,” The researchers wrote in Frontiers in Cardiovascular Medicine.

“The highest CVD mortality risks were observed for magnesium intake below median intake. Estimates of protective risk for CVD mortality were shown for magnesium intakes above adequate intake. “

Different requirements

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

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