If you’ve ever perused the supplement aisle for magnesium, you know there are plenty of options. This is because many magnesium supplements are mixtures of different types. Fiorella noted that she can tailor the supplements to her symptoms. “For example, if you have constipation and a lot of cramps, I would use magnesium citrate because it is bioavailable so it is easily absorbed,” he said.

What is magnesium used for?
Magnesium helps more than 300 enzymes create chemical reactions in the body. So it is good for general health. And this may be especially true for women and people who were assigned female at birth.
“In general, we have a deficiency of magnesium in our diet and there is a lot of association with menstrual and hormonal-type problems, such as painful periods or menstrual migraines due to this deficiency,” Fiorella said. A supplement can also help with cramps and also general fatigue during menstruation.
Research is being done on the benefits of magnesium, but studies show that magnesium may benefit certain health conditions. These may include:
Studies show higher magnesium levels can reduce the risk of cardiovascular disease and stroke. In one study In postmenopausal women, low magnesium intake was associated with an increased risk of heart failure.
Magnesium plays a role in control blood sugar levels. And people who consume less magnesium tend to have higher blood sugar levels and a increased risk of type 2 diabetes.
Studies show that taking a magnesium supplement can help prevent migraine attacks in some people. “I’ve seen really good benefits for people when they start taking daily supplements with a reduction in the number of migraines they have. It’s not good for stopping a migraine once it starts, but it’s good for prevention,” Fiorella said.
