Magnesium oxide as a supplement: Benefits, Side Effects, Dosage, and Interactions
Benefits, Side Effects, Dosage, and Interactions
Magnesium oxide is a supplement often used to treat migraine and constipation. It may provide other health benefits, including potentially lowering blood pressure and blood sugar levels.
Magnesium is a mineral that’s needed for many bodily processes, including blood sugar regulation, nerve function, energy production, and DNA synthesis (1).
It’s found in a number of foods but can also be taken as a dietary supplement. These supplements contain different forms of magnesium, including magnesium citrate, magnesium glycinate, and magnesium oxide.
Magnesium oxide is one of the most common forms sold in supplement form, either as a stand-alone supplement or in multinutrient products.
This article explains everything you need to know about magnesium oxide, including how it compares with other forms of magnesium, its potential benefits and side effects, and how to take it.
Magnesium oxide is an inorganic salt of magnesium formed with ions of magnesium and oxygen (2).
It’s one of many forms of magnesium available for purchase in supplement form. It’s added to dietary supplements as well as over-the-counter medications used to treat constipation, indigestion, and headaches.
Compared with other forms of magnesium, it may be less effective at raising blood magnesium levels (3).
How does it compare with other forms of magnesium?
Magnesium oxide and other inorganic salts of magnesium like magnesium carbonate are high in elemental magnesium, which is the total amount of magnesium in a supplement (3).
However, they have a low solubility rate, making them less bioavailable than other forms of the mineral. So, even though magnesium oxide supplements provide a good amount of magnesium, it’s not the most available form for your body to utilize (3).
A 2019 study confirmed this by testing 15 magnesium supplements and finding that a supplement containing only magnesium oxide had the lowest bioavailability (3).
Meanwhile, a supplement with both inorganic and organic magnesium salts — magnesium oxide and magnesium glycerophosphate, respectively — had the highest bioavailability (3).
Because of its low absorption rate in your intestines, magnesium oxide may lead to digestive effects like diarrhea. In fact, its strong laxative effects are why it’s commonly used to treat constipation (3).
A 2017 rat study demonstrated its low absorption rate, concluding that only 15% of orally administered magnesium oxide was absorbed, while 85% was excreted in the feces. Older research suggests the absorption rate is even lower in humans (4, 5).
In contrast, magnesium citrate, magnesium acetyl taurate, magnesium malate, and magnesium glycinate all have high absorption rates and are more effective at increasing magnesium levels in the body (6, 7, 8, 9, 10).
Still, magnesium oxide has been shown to offer several benefits and is commonly used to treat medical conditions like chronic constipation.
Summary
Magnesium oxide is an inorganic salt of magnesium. Even though it contains high amounts of magnesium, it has low absorbability in the body.
Still, it has been shown to offer health benefits like constipation relief.
Research shows that magnesium oxide is effective at treating certain medical conditions.
May help treat headaches
Magnesium is needed for proper nerve cell functioning. As such, a deficiency in this mineral can lead to migraine headaches.
Studies show that magnesium oxide may reduce headache symptoms. It may even be as effective as some migraine headache medications (11).
For example, a 2021 randomized, controlled, double-blind study in 63 people who experienced migraine found that taking 500 mg of magnesium oxide daily reduced migraine frequency as effectively as a migraine medication called valproate sodium (12).
Older research also suggests that magnesium oxide may reduce migraine in children (13).
However, other forms of magnesium like magnesium sulfate and magnesium citrate may be more effective at treating migraine, as they are typically better absorbed (14, 15, 16).
May reduce stress and anxiety
Magnesium plays an important role in your body’s stress response. In fact, studies have shown that people who experience frequent stress tend to have lower magnesium stores (17).
Some studies have shown that supplementing with magnesium may help reduce levels of stress and anxiety in certain populations.
For example, a 2017 review of 18 studies found that magnesium oxide may reduce stress and anxiety in women with premenstrual syndrome, but only when combined with vitamin B6 (18).
Despite these promising results, researchers acknowledge that the quality of existing studies on the subject is poor, and future well-designed studies are needed (18).
Helps treat constipation
One of the most common uses of magnesium oxide supplements is constipation treatment. The supplement has an osmotic effect, meaning it draws water into the intestines to cause a laxative effect that can help relieve constipation in both children and adults.
In a small 2019 randomized, double-blind, controlled study, 34 women with mild to moderate constipation were treated with either 1.5 grams of magnesium oxide or a placebo daily for 4 weeks (19).
Many women in the magnesium group experienced significantly improved bowel movement frequency, stool form, colonic transport time, and quality of life compared with the placebo group (19).
In fact, over 70% of those treated with magnesium oxide reported overall symptom improvement, compared with only 25% of those in the placebo group (19).
Similarly, a study in 90 people with constipation found that taking either 1.5 grams of magnesium oxide or 1 gram of senna, another laxative, significantly improved spontaneous bowel movements and constipation-related quality of life compared with a placebo (20).
Magnesium oxide has also been shown to prevent constipation after surgery, treat opioid-induced constipation, and improve functional constipation in children (21).
That said, while magnesium oxide has been shown to be safe for treating constipation, it may lead to dangerously high magnesium levels in certain populations, such as those with kidney impairment and older adults (5).
May lower blood pressure
Magnesium oxide supplements may help reduce elevated blood pressure levels.
A 2018 study in 48 people with high blood pressure found that treatment with 300 mg of magnesium oxide per day for 1 month significantly decreased both systolic (the top number) and diastolic (the bottom number) blood pressure (23).
Researchers theorize that the supplement may lower blood pressure by decreasing cellular calcium levels to relax smooth muscle cells and widen blood vessels (23).
May lower blood sugar levels
Magnesium supplements may lower blood sugar levels in people with diabetes.
For example, supplements containing magnesium oxide and zinc have been shown to lower blood sugar levels in people with type 1 diabetes, type 2 diabetes, and gestational diabetes, which is diabetes that can occur during pregnancy (24).
In a 2015 study, 70 women with gestational diabetes supplemented with either 250 mg of magnesium oxide or a placebo daily for 6 weeks (25).
The magnesium oxide treatment significantly improved blood sugar levels. It also reduced triglyceride levels and the inflammatory markers C-reactive protein (CRP) and malondialdehyde, compared with the placebo group (25).
Magnesium oxide supplements have also been shown to improve blood sugar management in Egyptian children with type 1 diabetes and Iranian adults with type 2 diabetes (26, 27).
Summary
Magnesium oxide may help treat migraine and constipation, reduce blood pressure, improve blood sugar management, and decrease levels of stress and anxiety in certain populations.
While supplementing with magnesium oxide may offer some benefits, there are potential side effects to consider.
Magnesium oxide is generally safe when used in appropriate doses. However, taking large amounts over long periods can lead to high blood magnesium levels, or hypermagnesemia, which is a serious condition that can be fatal (28, 29).
Groups particularly at risk of developing hypermagnesemia include those with kidney disease, older adults with bowel disorders, and those taking 1,000 mg of magnesium oxide or more per day (28, 30).
A 2019 case series discussed four cases of hypermagnesemia, one of which was fatal. All of the patients were over 65 years old and had kidney disease (30).
As such, researchers urge healthcare professionals to be aware of this risk and monitor magnesium levels in those being treated with magnesium oxide and other forms of magnesium (30).
Magnesium oxide may also result in digestive side effects like bloating and diarrhea, especially when taken at higher doses (31, 32).
What’s more, the supplement may suppress the absorption of certain medications, including antipsychotic and antidepressant drugs, as well as those used to treat urinary incontinence and Parkinson’s disease (33, 34, 35).
If you’re interested in taking magnesium oxide, consult your healthcare professional to determine whether it’s appropriate and safe for you.
Summary
High doses of magnesium oxide may cause dangerously high blood magnesium levels, which is more likely in specific populations.
It may also cause side effects like bloating and diarrhea and reduce the effectiveness of certain medications.
How much magnesium oxide to take depends on the treatment purpose.
For example, magnesium oxide is used to prevent migraine with daily 500-mg doses (12).
Meanwhile, 300 mg per day has been shown to help treat high blood pressure, while 250 mg per day may help lower blood sugar levels in women with gestational diabetes (23, 25).
Higher doses of the supplement — usually over 1 gram — are used to treat constipation, though daily doses as low as 250 mg may be enough for some people (5).
Summary
Magnesium oxide dosing generally ranges from 250–1,000 mg per day depending on what it’s being used to treat. Taking too much can be dangerous. Speak with your healthcare professional if you have questions regarding dosing or side effects.
Magnesium oxide is a form of magnesium commonly taken as a dietary supplement. It has a lower bioavailability than other forms of magnesium, but it may still offer benefits.
Mainly, it’s used to treat migraine and constipation. It may also help reduce blood pressure, blood sugar, and anxiety in certain populations.
Taking too much magnesium is dangerous and can cause elevated blood magnesium levels, digestive side effects, and hindered absorption of certain medications.

Applications
Magnesium oxide is used in a wide variety of industries.
Food industry
The compound is known as emulsifier E530, a safe food additive. Approved for use in EU countries, in Russia and Ukraine.
Used as an emulsifier and stabilizer in food production.
Introduced into:
- powdered milk and cream
- cocoa products
- chocolate sweets and desserts
- edible oils (butter, margarine, spread).
Used in the production of oils and fats. The presence of MgO in the composition accelerates the hydrogenation of the product (transition of oil from a liquid state to a solid state). Does not change the qualitative characteristics of fats.
Magnesium oxide is added to bulk food products to prevent their clumping and caking.
The amount of the substance added to food has no effect on the body.
Medicine and pharmaceuticals
In medicine, it is used even more actively than in food production. MgO is an ingredient in many drugs.
- Recommended as a means of normalizing hyperacidity of the stomach. Due to this property, it is also used as an antidote for acid ingestion.
- It is used to treat peptic ulcers, as well as pancreatitis, dyspepsia, acute and chronic gastritis, duodenal ulcers.
- Used as a remedy for magnesium deficiencies that result from diabetes or malnutrition. The substance strengthens bones, normalizes the functioning of the nervous system, and ensures the smooth functioning of the heart. To do this, magnesium oxide is introduced into the composition of vitamin-mineral complexes, which can be used independently. It is not recommended for people with normal blood levels of magnesium, allergic to the compound, as side effects are possible.
- Works as a prophylactic to prevent the formation of oxalates in the kidneys. For persons with chronic renal failure and other problems in the excretory system, the drug can be used only on the advice of a doctor.
- Used as a mild laxative.
- It is prescribed for lactating and pregnant women to support the mineral balance in mother and child.
The substance is not harmful when used correctly. An overdose occurs only when the digestive and excretory systems of the body are disrupted.
For internal use, it is sold in powder, tablets, as part of mineral and vitamin complexes.
Production of cosmetics
- Finely dispersed magnesium oxide has a crumbly, friable structure. This allows you to include it in the composition of powder, blush, talc and powders, which do not form lumps even during long-term storage.
- The stabilizing and absorbent properties of the substance have also found application – magnesium oxide is part of lotions, masks, cosmetic preparations against blackheads, baby powders, antiperspirants. All of these skin care products have anti-inflammatory properties, remove excess sebum from the skin.
- Together with zinc, magnesia gives the skin a matte finish and tightens pores, and also exhibits whitening properties.

- Bonding is essential in paper making.
- Demanded in metallurgy and metal processing.
- Used in the production of polymers, rubber.
- Used for the production of optical materials that are superior to ordinary glass in many ways.
- In electrical engineering, it plays the role of a filler for heating elements.
- Used in electronics as a cleaning agent for electronic devices.
- Used in waste disposal as a substance that inhibits the dissolution of radionuclides.
- Connection whiteness is reference
Precautions for handling the substance
Among the negative effects on humans is a general toxic effect upon contact with the substance without protective equipment, if it comes into contact with the skin, it can cause severe irritation, the same effect awaits in case of contact with mucous membranes shell. The maximum permissible concentration inside the working area should not exceed – 1 mg/m.
When working with the substance, it is imperative to use personal protective equipment, such as: respirators, rubber gloves, goggles.
In the premises where work is carried out, it is necessary to ensure the presence of a general supply and exhaust ventilation.

Features of obtaining and using oxide in the form of food additive E530 – a review from Prime Chemicals Group Does not cake, does not dust.
Its formula is MgO. In the literature, it can be called burnt magnesia, magnesium oxide. A highly purified substance is used as a food additive E530. It is sparingly soluble in water, but absorbs well any liquids, including water and oils. Very tough. When dissolved in water, it converts to hydroxide.
Magnesium oxide occurs naturally as the mineral periclase.
Obtaining burnt magnesia
In industry, magnesium oxide, the use of which is associated with many sectors of the economy, is obtained from natural mineral magnesium-containing raw materials. These are: magnesite (MgCO3), dolomite (MgCO3∙CaCO3), brucite (Mg(OH)2), white magnesia (3MgCO3∙Mg(OH)2∙3h3O), bischofite (MgCl2∙6h3O). The starting material is fired in different ways. The properties of the finished product depend on the firing technology: its solubility, water absorption, particle size and weight, color.
In laboratories, the substance is obtained:
• direct synthesis from Mg and O2;
• decomposition of salts or magnesium hydroxide.
Applications of magnesium oxide
Applications of magnesium oxide are based on its properties. There are heavy and light varieties of burnt magnesia. One form or another is in demand:
• for the production of refractory building materials, xylitol, fire-resistant grades of magnesian cements and concretes;
• as a cleaning agent for certain petroleum products;
• as a vulcanization activator and filler in the rubber industry and the automotive industry;
• as an abrasive for cleaning “delicate” surfaces, eg in the electronics industry;
• in the analytics and paint industry, a white standard with absolute reflectivity;
• anti-slip agent for hands and feet of athletes, climbers;
• for the manufacture of paper, LCD screens;
• in radioactive waste processing;
• for purification of water, sewage, industrial gases, restoration of soils contaminated with metals;
• in agriculture to improve the flowability of fertilizers; as a microadditive containing magnesium, it is included in livestock feeds.
Food Grade Reagent Use
E530 food additive is a stabilizer and emulsifier in food production. It is used in the production of milk powder and cream, chocolate and cocoa powder, edible oils, spreads, margarines, cooking oil.
Food grade magnesium oxide used in medicine, pharmaceuticals and cosmetics. Only light grades of magnesia are suitable for these purposes. The powder has antibacterial properties, strengthens bones, intestinal muscles, has a beneficial effect on the heart, prevents caking of bulk products, narrows pores, whitens and dries the skin, absorbent. Also, this:
• antidote for acid poisoning;
• agent for neutralization of high acidity of gastric juice, treatment of heartburn, treatment and prevention of peptic ulcer and urolithiasis, gastritis, pancreatitis, constipation and other diseases;
• component of some drugs and most vitamin complexes;
• consistency stabilizer for creams, masks, deodorants;
• component of powders, talcs, powders, rouges, decorative cosmetics, sunscreens, shampoos.
Safety precautions
The widespread use of magnesium oxide is due to the recognized safety of the substance, even if swallowed. It does not burn or explode, is practically not absorbed into the bloodstream and is easily excreted from the body. But, like almost all bulk substances, the powder irritates the mucous membranes of the eyes and respiratory organs. Therefore, personnel working with the reagent must use respirators and goggles that protect the eyes, mouth and nose. The working room should be equipped with general mechanical ventilation.
Store the reagent in an airtight container or container in a dry warehouse, as it absorbs moisture from the air.
