Manages Gastrointestinal Problems
When magnesium oxide is mixed with water, it is called magnesium hydroxide—this mixture can help with naturalizing stomach acids. One study of 276 people found that a combination of simethicone (an agent used to decrease gas), activated charcoal, and magnesium oxide was more effective than a placebo for managing indigestion.2 Many antacids use magnesium hydrogen-based substances, but few studies have looked at the effectiveness of magnesium oxide alone.


Relieves Depression
Magnesium oxide may help manage depressive symptoms and behaviors, as it may have positive mental health and stress reduction effects. Several studies have confirmed an association between magnesium intake and depression.3


Reduces Blood Pressure and Risk of Stroke
Research from the American Journal of Clinical Nutrition finds that diets high in magnesium can reduce the risk of stroke, especially ischemic strokes.4

 This type of stroke occurs when the artery to the brain is blocked. The cause of most ischemic strokes is high blood pressure, and research finds that magnesium supplementation can help to lower blood pressure.

Reduces Migraines
Magnesium oxide supplementation may reduce the number and intensity of migraines. Research shows the majority of migraine sufferers are magnesium deficient.5 The American Migraine Foundation finds magnesium to be an ideal treatment for migraine relief and prevention.6

Lowers Colorectal Cancer Risk
Some research indicates magnesium oxide supplements may reduce the risk of colorectal cancer. Research reported in the American Journal of Clinical Nutrition finds that high doses of magnesium are linked to a lowered risk of colorectal tumors. The report suggests that for every 100-milligram increase in magnesium, the risk of developing a tumor is reduced by 12 percent.7
