Magnesium oxide is one of a few types of magnesium supplements you can get without a prescription. It is also an ingredient in some over-the-counter (OTC) medications. It is most commonly used to treat low magnesium levels and constipation. It has also been studied for its effects on blood pressure, type 2 diabetes, and migraines.
Magnesium oxide is generally safe, although it may cause stomach aches and diarrhea. The recommended daily magnesium intake from all sources is between 310 milligrams (mg) and 400 milligrams for younger adults and between 320 milligrams and 420 milligrams for older adults.
This article discusses the possible uses of magnesium oxide, including the side effects, risks, interactions, and how it differs from other forms of magnesium (such as magnesium citrate).
Uses of Magnesium Oxide
Supplement use should be individualized and vetted by a healthcare professional, such as a registered dietitian nutritionist, pharmacist, or healthcare provider. No supplement is intended to treat, cure, or prevent a disease.
Magnesium oxide is a magnesium mineral supplement that has magnesium and oxygen ions.
Magnesium Deficiency
Magnesium deficiency in the general population is uncommon, but low intakes (e.g., older adults) or losses caused by health conditions (e.g., gastrointestinal diseases, type 2 diabetes, alcohol misuse) can lead to a magnesium deficiency.
Early signs of a magnesium deficiency include:
When the deficiency gets worse, symptoms can include:
You can get magnesium through your diet and supplements. Before starting any supplements, please discuss them with your healthcare provider.
Constipation
Magnesium is an ingredient in some laxatives (e.g., Philips' Milk of Magnesium). The supplement draws water into the intestines to soften stool, making it easier to pass (osmotic effect).
One randomized, double-blind, placebo-controlled trial looked at the effects of magnesium oxide in adults with chronic mild-to-moderate constipation. Seventeen people took magnesium oxide for 28 days and 17 took a placebo.
At the end of the study, magnesium oxide significantly improved participants’ overall symptoms, including spontaneous bowel movement, stool form, colonic transit time, and abdominal symptoms compared to taking the placebo.
Magnesium oxide should only be used as a short-term treatment for constipation. If you have constipation, talk to your healthcare provider about the best treatment for you. Call your provider if your constipation does not get better or gets worse after trying magnesium oxide.

Blood Pressure and Risk of Stroke
Magnesium oxide might help reduce high blood pressure (hypertension) and lower the risk of stroke.
A review that looked at seven prospective studies found that diets high in magnesium can reduce diastolic blood pressure and may reduce the risk of stroke (especially ischemic strokes, which happen when an artery in the brain is blocked. This kind of stroke is often caused by high blood pressure).
Another systematic review of 49 studies on oral magnesium supplementation and blood pressure showed promising but conflicting results:
Type 2 Diabetes
Diets high in magnesium have been associated with a lower risk of type 2 diabetes.
One long-term meta-analysis of seven studies including 286,668 people found that 100 milligrams per day in total magnesium intake significantly lowered the risk of diabetes.
Another meta-analysis of 13 studies demonstrated a dose-dependent association between magnesium intake and type 2 diabetes risk. However, this was only statistically significant in people who were overweight.
However, very few short-term clinical trials have been done on magnesium oxide’s effects on controlling type 2 diabetes. The American Diabetes Association (ADA) states there is not enough research to support using magnesium supplements to improve blood glucose in people with type 2 diabetes.
If you have diabetes, talk to your provider before starting magnesium oxide supplementation.
Migraines
Magnesium oxide supplementation may reduce the number and intensity of migraines.
A randomized, double-blind crossover study showed that taking 500 milligrams of magnesium oxide appeared to be as effective as valproate sodium in preventing migraine attacks. Sixty-three people in the study took either magnesium oxide or valproate sodium.
The American Academy of Neurology and the American Headache Society concluded that magnesium therapy is "probably effective" for migraine prevention, but research is limited.
It’s also important to note that the typical dose of magnesium used for migraine prevention is higher than magnesium's tolerable upper limit (UL). Therefore, it should only be used under the supervision of a healthcare provider.
Please discuss the use of magnesium oxide supplements with your healthcare provider before taking them if you have migraines.
How It Compares to Other Forms of Magnesium
Other types of magnesium supplements include:
Magnesium chloride
. This form of magnesium supplement is often used in topical products, like skin creams. It's better absorbed by the body than magnesium oxide.Magnesium citrate
. This form of magnesium supplement is one of the most widely used. It's one of the best forms of magnesium absorbed by the body. It can have similar uses to magnesium oxide, including as a laxative.Magnesium glycinate
. This form of magnesium is very helpful in fixing a deficiency because the body absorbs it well, and it is less likely to cause diarrhea than magnesium oxide.Magnesium lactate
. This form of magnesium is bound withlactic acid
, which your muscles make when they are working hard. It's more absorbable than magnesium oxide and does not usually cause diarrhea. Sometimes, this form of magnesium is added to foods and drinks to help balance their acidity.Magnesium malate
. This form of magnesium is absorbed well by the body and some people claim that it helps with whole-body symptoms like fatigue and muscle pain.Magnesium orotate
. This form of magnesium hasorotic acid
, which helps the magnesium get into the body's cells. It can be used as a supplement to help with deficiencies but is not as popular as other forms of magnesium, and may not be safe at higher doses.Magnesium sulfate
. This form of magnesium is commonly known as Epsom salt, which some people use to make baths that are soothing for sore muscles. It's generally not the preferred choice for trying to correct a magnesium deficiency because it can be dangerous if you take too much.Magnesium L-threonate
. This form of magnesium is combined withthreonic acid
, which comes from vitamin C. It can be used to help with a deficiency and may have some other health benefits as well, such as for immune function.What Are the Side Effects of Magnesium Oxide?

Upset stomach and diarrhea are the most common side effects of magnesium oxide. Taking magnesium oxide with food can often prevent these side effects. If side effects do not get better or are getting worse, it is best to talk to your healthcare provider.
Severe allergic reactions to magnesium oxide are rare. However, seek immediate medical help if you develop:
Precautions
People with kidney problems should ask their providers before starting magnesium oxide supplements. In addition, pregnant and lactating people, as well as children, should avoid magnesium oxide supplements because the risks to these groups are unknown.
Dosage: How Much Magnesium Oxide Should I Take?
Always speak with a healthcare provider before taking a supplement to ensure that the supplement and dosage are appropriate for your needs.
The following is the Recommended Dietary Allowance (RDA) for magnesium:
Magnesium oxide supplements should be taken by mouth with meals to reduce the chances of stomach upset. Do not crush or chew the supplements, as consuming them this way can increase the risk of side effects. If taken in liquid form, shake and measure the proper dose according to the instructions on the supplement's label.
Discuss your use of magnesium oxide with your provider to find out the safest and most effective amount to take for your needs.
What Happens If I Take Too Much Magnesium Oxide?
It is possible to take too much magnesium oxide. Large doses of magnesium oxide can cause magnesium toxicity, but this is more likely in people with kidney problems.
Taking too much magnesium oxide may cause:
If you have any of these symptoms after taking magnesium oxide, seek medical care right away.
Interactions
Magnesium oxide may prevent the absorption of several medications. Before starting magnesium oxide supplementation, please discuss the prescription and OTC medications, vitamins, or herbal supplements that you take with your healthcare provider.
Magnesium oxide might reduce how well the Parkinson's disease treatment Sinemet (levodopa and carbidopa) works. However, more studies are needed.
Other medications that can interact with magnesium oxide include:
Bisphosphonates
such as Fosamax or Binosto (alendronate
) (take magnesium-containing supplements at least 2 hours from when you take bisphosphonates)tetracyclines
andquinolones
(take antibiotics at least two hours before or 4 to 6 hours after a magnesium supplement)furosemide
), Bumex (bumetanide
), and Microzide (hydrochlorothiazide
)esomeprazole magnesium

Other interactions may occur. Before starting magnesium oxide, ask your healthcare provider or pharmacist for a complete list of potential drug, supplement, and food interactions.
Carefully read a supplement's ingredient list and nutrition facts panel to know which ingredients and how much of each ingredient is included. Please review this supplement label with your healthcare provider to discuss any potential interactions with foods, other supplements, and medications.
Sources of Magnesium Oxide
Magnesium is found in many plant and animal foods and beverages, including green leafy vegetables (spinach), legumes, nuts, seeds, and whole grains. Usually, foods that are higher in fiber are rich in magnesium.
Magnesium oxide supplements are available OTC without a prescription. Magnesium oxide is sold under several brand names. Your healthcare provider or pharmacist can advise you on which brand might fit your unique situation and overall health.
Before starting a magnesium supplement, it is a good idea to have your magnesium levels checked by your provider. There is no way to know if the symptoms you are having are related to a magnesium deficiency, another nutritional deficiency, or an illness. You should tell your provider about any health conditions you have and all medications you’re taking to avoid interactions or adverse reactions.
Summary
Magnesium oxide is a type of magnesium. It’s often an ingredient in laxatives and supplements.
Getting enough magnesium is important for good health. Without it, the body cannot function properly. Eating magnesium-rich foods, like green leafy vegetables, legumes, nuts, seeds, and whole grains, is usually enough to get the magnesium you need.
It’s important to make sure you get enough magnesium without getting too much. You should always talk to your provider before starting any supplement. If you think you have low magnesium levels, ask your provider to check them.
What is the best source of magnesium?
The best way to get magnesium is through your diet and eating a variety of magnesium-rich foods, such as spinach, legumes, nuts, seeds, and whole grains.
Supplements are an option for maintaining magnesium levels in people whose levels remain low despite diet changes. Please talk to your healthcare provider before starting a magnesium oxide supplement.
How do I know if I should take a magnesium oxide supplement?
A healthcare provider can assist you in determining if magnesium oxide supplements are needed for maintaining and/or increasing magnesium. A blood test is usually used to check the level of magnesium in your blood.
Anyone who thinks their magnesium is low should talk to their healthcare provider before starting a supplement.
Magnesium is a type of electrolyte (an electrically-charged mineral categorized as a healthy metal) responsible for regulating many bodily functions including muscle contraction, the central nervous system, blood pressure, blood sugar levels and more.
Due to its various roles within the human body, sufficient magnesium is necessary for the body to function properly. The Recommended Dietary Allowance for magnesium varies based on age and gender, ranging from 30 milligrams to 420 milligrams. Regularly low magnesium levels can lead to a magnesium deficiency, which could cause quite a few complications.
“Magnesium deficiency (hypomagnesemia) can be associated with negative health outcomes including neurologic, muscular and cardiovascular conditions,” says Michelle Pearlman, M.D., a board-certified gastroenterologist based in Florida.
Certain health conditions like diarrhea and chronic alcoholism can lead to persistent low intake or excessive losses of magnesium, as well as common medications. Blood pressure medications in particular are among those that may deplete magnesium.
Some foods, like dark leafy green vegetables, are rich in magnesium. However, the National Institutes of Health notes that many people in the U.S. receive less than the recommended amount of this important nutrient through diet alone, and deficiency is associated with inflammation. Further, fertilizers and pesticides can prevent magnesium absorption in vegetable food sources.
For those needing an additional source of magnesium, dietary supplements are a viable second option. Magnesium supplements come in a number of different forms, and some are more easily absorbed by the body than others. Among the different magnesium supplements is magnesium oxide.
