Overall, compared to those who got the least magnesium in their
diet, those who consumed the most magnesium were much less
likely to have died from heart disease. This was particularly
true for women, with those taking the most magnesium 36 percent
less likely to have unhealthy hearts compared to women who got
the least magnesium. Women who got the most magnesium were more
likely to avoid dying from stroke, heart disease, heart failure,
and all cardiovascular disease. For men, compared to those who
got the least magnesium, those who got the most magnesium were
half as likely to have a stroke. These men were also about half
as likely to have a blood clot in the brain, decreased blood
flow to the heart, and heart failure—the reduced ability of the
heart to pump blood. Doctors concluded getting enough magnesium
in the diet can help extend life by improving blood vessel and
heart health.
