Magnesium is one of seven essential macrominerals. These macrominerals are minerals that people need to consume in relatively large amounts — at least 100 milligrams (mg) per day. Microminerals, such as iron and zinc, are just as important, though people need them in smaller amounts.
Magnesium is vital for many bodily functions. Getting enough of this mineral can help prevent or treat chronic diseases, includingTrusted Source Alzheimer’s disease, type 2 diabetes, cardiovascular disease, and migraine.
