Magnesium malate is a combination of magnesium and malic acid. Its many health benefits include being anti-inflammatory, alleviating depression, and increasing your ability to tolerate exercise. It can be helpful for treating or preventing many health conditions, including:

  • Alzheimer’s diseaseType 2 diabetesOsteoporosisHeadache and migraineAmyotrophic lateral sclerosis (ALS)Fibromyalgia and related conditions

Magnesium and malic acid both have health benefits and can be taken separately. However, studies suggest your body doesn’t absorb magnesium well when it’s by itself. Binding it to malic acid helps your body use magnesium.

This article looks at the health benefits of magnesium malate, how to get more through your diet, what research says about its use in neuromuscular conditions, the possible risks, dosages, and what to look for when buying magnesium malate supplements.

What Is Magnesium Malate Good For?

Magnesium and malic acid both have several health benefits. Combining them gives you the benefits of both.

Magnesium

Magnesium is the fourth most plentiful mineral in your body. It plays a role in more than 300 reactions with myriad impacts on your health. These include:

  • Producing adenosine triphosphate (ATP), which is the primary form of energy used by your cellsMaking DNA and RNA (genetic material)Forming proteins that your body needs for a variety of functionsRegulating muscle contractionControlling blood pressureInsulin use, which affects blood sugar regulationCardiac (heart) excitabilityContraction and relaxation of blood vesselsNerve transmission

Because it’s involved in all these important functions, getting enough magnesium may help prevent or treat a wide range of chronic illnesses. These include:

  • Neuromuscular conditions: Muscular dystrophies, myopathies (diseases of muscle-fiber dysfunction), amyotrophic lateral sclerosis (ALS), myasthenia gravis, Charcot-Marie-Tooth disease
  • Neurological disorders: Alzheimer’s disease, Parkinson’s disease, epilepsy, stroke
  • Cardiac (heart) problems: Arrhythmias (heart-rhythm abnormalities), hypertension (high blood pressure), heart muscle spasms, fatal heart disease
  • Metabolic disorders: High cholesterol and triglycerides, problems with vitamin D use and bone health, insulin resistance (pre-diabetes), type 2 diabetes
  • Central sensitivity syndromes: Fibromyalgia, myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), anxiety, depression, dysmenorrhea (painful periods), headache, migraine
  • Pregnancy complications: Miscarriage, premature labor, eclampsia
  • General problems: Poor memory, asthma, seizures, paresthesias (abnormal nerve sensations), osteoporosis, sleep disorders, impaired athletic performance, lowered stress tolerance, lethargy, weakness, irritability, electrolyte imbalances

Research also suggests it can help recovery after a nerve injury.

Malic Acid

Malic acid has far fewer roles in your body but still may help prevent or treat some conditions and bolster certain process in your body. Malic acid plays a role in:

  • Energy production via ATP
  • Muscle pain
  • Recovery from exercise
  • Skin health (when used topically)
  • Preventing calcium-oxalate kidney stones

For people who get that type of kidney stone, supplements containing calcium citrate and calcium malate are a source of calcium that doesn’t contribute to stone production.

Research has also suggested that it can help your body absorb medications, and because of this, it’s often given alongside medicines for liver dysfunction or high levels of ammonia in the blood.

Possible Side Effects

Magnesium can have a laxative effect. High doses of magnesium malate are linked with intestinal problems such as:

  • Persistent diarrheaUpset stomachVomitingGas and bloatingCramping

Malic acid hasn’t been researched enough to establish side effects.

Drug Interactions

Some research suggests that magnesium may interact badly with heart medications. Other, unknown interactions are possible.

Be sure to go over your complete list of medications and supplements with your healthcare provider and pharmacist. They can help you identify potential problems.

Contraindications

It’s well-established that magnesium can lower blood pressure. You shouldn’t take it if you’re at risk for hypotension (low blood pressure).

If you’re on medication for hypertension (high blood pressure), ask your healthcare provider if magnesium is safe for you. Combining magnesium with your medication may lower your blood pressure too much.

Dosage and Preparation

Magnesium malate supplements are most often taken orally (by mouth) with a meal.

According to the National Institutes of Health (NIH), the recommended daily allowance (RDA) of magnesium, varies by age, gender, and whether you’re pregnant or lactating.

No recommended daily allowance has been established for malic acid. Daily dosages of malic acid are generally between 1,200 milligrams (mg) and 2,800 mg.

These dosages are general guidelines. You should check with your healthcare provider to see what dosage is right for you based on your health history and current medications.

What to Look For

In the United States, supplements aren’t regulated like pharmaceutical products. When buying them, make sure to check the Supplement Facts. That lists the active ingredients per serving plus any added ingredients such as fillers, binders, and flavorings.

Also, look for a seal of approval from a third-party quality testing organization such as:

  • ConsumerLabU.S. PharmacopeiaNSF International

Seals from these organizations don’t guarantee safety or effectiveness, but they do mean the product matches what’s on the label and is free from dangerous contaminants.

Dietary Sources

You can increase magnesium levels through your diet, as well. Foods rich in magnesium include:

Absorbable Forms

Other forms of magnesium that may improve absorption include:

  • Pumpkin and chia seedsAlmonds, cashews, and peanutsBoiled spinachShredded wheat cerealSoymilkBlack beansEdamamePeanut butterPotatoesRiceYogurtOatmeal

You can get malic acid from several fruits and some vegetables. Foods rich in malic acid include:

A 2016 review of research found that industrial agriculture has lowered the amount of magnesium the average person gets through foods. That means you may need supplements to correct a magnesium deficiency.

Summary

Magnesium malate is a combination of magnesium and malic acid. The combination makes it easier for your body to absorb and use magnesium.

Both supplements have important health benefits and are used to treat and prevent myriad conditions, including Alzheimer’s disease, diabetes, asthma, fibromyalgia, high blood pressure, and some pregnancy-related problems.

Digestive side effects are possible. Magnesium may interact badly with heart medications.

Recommended daily amounts of magnesium vary based on age, sex, pregnancy/lactation status, and health conditions. Recommendations aren’t established for malic acid.

With this or any supplement, ask your healthcare provider whether it’s safe and what dosage is right for you. Look for products that are certified by independent testing organizations. You can also get magnesium and malic acid through certain foods.
