Sunergetic Magnesium Complex puts two types of magnesium to work in one supplement: magnesium citrate and magnesium oxide. Each type of magnesium is linked to an array of health benefits, including magnesium citrate for better sleep and magnesium oxide for migraine relief.
This supplement also delivers a hefty dose of its magnesium blend, at 500 milligrams per serving (119 percent of daily value). Be aware, that dosage is significantly higher than the Tolerable Upper Intake Level for magnesium supplementation (350 milligrams per day). Excess magnesium could result in side effects such as nausea or diarrhea, so check with a healthcare professional before taking this or any other magnesium supplement.
Registered dietitian Destini Moody advises caution with supplements that exceed the Tolerable Upper Intake Level, or UL. "Higher doses of magnesium supplements may be warranted in certain cases," says Moody, who specializes in sports performance, body composition changes and injury recovery. "Doses of up to 400 milligrams have been used to treat migraines, but it should be noted the subjects in which this was found effective were deficient before supplementing. The same dosage has been used to prevent the development of diabetes in those with prediabetes and to help lower lipid profiles in those with certain heart conditions." However, she adds that these doses were administered under the supervision of medical professionals and that she believes the findings of their effectiveness require more study.
Sunergetic Magnesium Complex is manufactured in a GMP-compliant, FDA-registered facility. The capsules are unflavored and vegetarian.

What Is Magnesium?
Magnesium plays a part in numerous bodily functions—over 300 enzyme systems, in fact—and is crucial for the healthy function of your brain, bones, muscles and blood. It's also a nootropic, a type of natural or synthetic cognitive-enhancing substance that can reduce anxiety, anger, depression and confusion.
"Magnesium is a mineral electrolyte that is best known for its calming properties," says Nastasi.
"It's thought to be one of the most commonly found nootropics, a buzzword that's going around the industry right now."
In the body, magnesium can be found within bones or on a cellular level. In food sources, it’s often associated with green vegetables, whole grains and seeds, as well as some fibrous fruits and vegetables like apples, broccoli and carrots.
Unfortunately, getting magnesium from food isn't as easy as it once was—which makes magnesium supplements all the more useful.
"Our soil is very magnesium-depleted," says Nastasi. "What this means is that plants that used to have a high concentration of magnesium no longer do. So a magnesium supplement might be beneficial for you."
Magnesium Benefits
Insomnia relief
Magnesium citrate and glycinate may be beneficial for sleep. One study reported improved insomnia for adults receiving 500 milligrams of magnesium per night. Try taking 200 milligrams of magnesium in these forms to start. Also, as a muscle relaxant, magnesium is helpful for calming down later in the day. It’s a possible addition or alternative to insomnia medication because it won’t make you drowsy the next day.
Anxiety
"The reason why magnesium is classified as a calming nootropic is because it's found to be extremely helpful in people who have anxiety," says Nastasi.
Most forms of magnesium can reduce anxiety and stress by relaxing your body. Many people opt to try magnesium before medication for anxiety because magnesium supplements have fewer side effects.
Muscle cramps
"Magnesium is essential for the nervous system to function properly, including muscle control and muscle contraction," says nutritionist and holistic health coach Christina Amado.
Magnesium can help reduce leg cramps, especially if you're pregnant. "Studies have shown that pregnant women suffering from nocturnal leg cramps may have a slightly higher success rate than the average person when taking magnesium," says Amado.
Also, magnesium supplementation can reduce muscle cramps after exercise, since exercise depletes your body’s magnesium stores. Amado recommends magnesium citrate, magnesium glycinate and magnesium oxide to help with leg cramps.
Heart health
"Magnesium is imperative for heart health because of the way it promotes healthy blood flow and encourages contraction of the cardiac muscles," says Amado. "When magnesium is deficient in the body, the heart is vulnerable to conditions such as calcified arteries, blood pressure issues and heart attacks."
The body's highest concentration of magnesium in the body is found in the left ventricle, according to Amado. By regulating the amount of calcium that enters the heart, it helps prevent a hyper-contraction of the muscle cells that can lead to angina or a heart attack.
For some congestive heart failure patients, magnesium supplementation has led to better outcomes and improved quality of life.

Bone building
To build strong bones, get enough Vitamin C and magnesium. Vitamin C is essential for collagen formation and bone development, and magnesium improves bone density (nearly 60 percent of magnesium is stored in the bones) to prevent osteoporosis. Magnesium also builds new bone cells and prevents bone inflammation.
Constipation relief
For constipation, try magnesium hydroxide or magnesium citrate. The hydroxide form is commonly called “milk of magnesia.” For these saline laxatives, the onset of effect is anywhere between 30 minutes and six hours. Saline laxatives draw water into the stool for an easier bowel movement. Be aware that magnesium hydroxide and citrate should not be used long-term for constipation. Check with your pharmacist or health provider for the best dosage.
Headache relief
Many specialists recommend magnesium oxide for migraine treatment and prevention. Magnesium is a nutraceutical, which is a nutrient that also has medicinal effects. For headaches or migraines, 400-600 milligrams of magnesium oxide may provide relief.
Mineral absorption and transport
Essential minerals like calcium and Vitamin D need magnesium to work. For example, magnesium turns Vitamin D into its active form, and activated Vitamin D helps your body use calcium to build healthy bones.
Cellular energy
As the fourth most abundant mineral in the body, magnesium plays a vital role in DNA and RNA synthesis. It’s an essential coenzyme that assists with hundreds of vital processes in your body.
High magnesium concentrations are found in the mitochondria of the cell. Magnesium also activates amino acid and protein synthesis. This is why magnesium is essential for cell function and energy production.
Diabetes
Some people with diabetes, particularly type 2, may have lower magnesium levels. Magnesium, insulin and glucose (otherwise known as blood sugar) are all interconnected. To ensure each is doing its job and functioning properly in the body, ensuring magnesium levels are healthy is crucial.
What to Consider Before Taking Magnesium
You may be wondering, "How much magnesium should I take? What kind of magnesium should I be using?" First things first—before taking magnesium think about other medications or supplements you may already be taking.
The RDA (Recommended Dietary Allowance) is how much you need daily for sufficient nutrition, and it reflects the dietary needs for 97–98 percent of all healthy individuals. According to the National Institutes of Health, these are the RDAs for different age groups and populations:
Recommended Dietary Allowances (RDAs) for Magnesium: Child to adult
| Age | Male | Female |
|---|---|---|
Four to eight years | 130 milligrams | 130 milligrams |
Nine to 13 years | 240 milligrams | 240 milligrams |
14 to 18 years | 410 milligrams | 360 milligrams |
19 to 30 years | 400 milligrams | 310 milligrams |
31 to 51+ years | 420 milligrams | 320 milligrams |
Recommended Dietary Allowances (RDAs) for Magnesium: Pregnancy and Lactation
| Age | Pregnancy | Lactation |
|---|---|---|
14 to 18 years | 400 milligrams | 360 milligrams |
19 to 30 years | 350 milligrams | 310 milligrams |
31 to 50 years | 360 milligrams | 320 milligrams |

Moody says it's also essential to consider the Tolerable Upper Intake Level for magnesium, which is 350 milligrams per day.
"While some water-soluble vitamins like Vitamin C can play a little more fast and loose with mega-dosing supplements due to the ease with which the body can clear the excess through urine, minerals like magnesium do not have the same luxury," says Moody. "It must be remembered that minerals like magnesium and iron are metals and aren't technically meant to be consumed in the quantities included in supplements, but in trace amounts from our food. So, it's advised that the public takes Tolerable Upper Intake Levels seriously when it comes to fat-soluble vitamins and minerals."
Moody also points out that the 350 milligram-per-day threshold is the most clinically observed dose that offers no risk of gastrointestinal side effects in most people, according to the The Institute of Medicine. However, Moody says exceeding that limit doesn't necessarily guarantee GI distress. "Many times, it depends on the individual's gut and the type of magnesium salt that is being used for supplementation."
Who Should Take Magnesium?
Magnesium is involved in over 300 biochemical reactions in the body, yet many people are magnesium deficient. Low magnesium, also known as magnesium deficiency or hypomagnesemia, can cause a host of health issues involving hormonal imbalance, lowered levels of calcium and potassium, neuromuscular and cardiovascular problems and more.
So how can you tell if you have low levels of magnesium? Here are some signs and symptoms:
Early signs
- Decreased appetite
- Nausea
- Vomiting
- Fatigue or weakness
Worsening symptoms
- Numbness
- Tingling
- Muscle cramps
- Abnormal heartbeat
- Seizures
Who’s at risk of magnesium deficiency?
Older adults are especially at risk for magnesium deficiency. Insulin resistance puts people with diabetes at risk for low magnesium levels. Stomach issues from chronic diarrhea or Crohn's disease can also increase your risk, as well as alcoholism or gastric bypass surgery.
Basically, anything that affects your nutritional absorption can alter serum magnesium levels and contribute to low magnesium.
Medications linked to magnesium depletion
Certain medications may also cause magnesium depletion, so check with your doctor to see if you should take a magnesium supplement with your prescriptions.
"If a medication alters the function of the gut or the digestive system, it is almost guaranteed to affect magnesium levels within the body," says Amado. "This same rule of thumb applies to synthetic hormones, either enhancing or suppressing, as well as cholesterol medications like statins."
Medications and treatments that deplete the body of proper magnesium levels include:
- Acid blockers
- Antacids
- Antibiotics
- Antiviral agents
- Blood pressure medications
- Central nervous system (CNS) stimulants
- Cholesterol agents
- Corticosteroids
- Hormone replacement therapies
- Oral contraceptives
- Immunosuppressants
"The reason cholesterol medications deplete magnesium from the body is because these prescription medications bind to the fats that are necessary for mineral absorption, therefore reducing the body's ability to utilize magnesium," says Amado. "Blood pressure medications are often diuretics, which remove excess fluid from the body, and magnesium can therefore be at risk from being removed from the body at too quickly of a rate, creating a deficiency."
Unfortunately, magnesium supplements can also cause interactions—which underscores the importance of talking to your healthcare provider before adding magnesium to your routine. We address potential interactions in the next section.
Who Shouldn’t Take Magnesium?
Here are some situations where you should avoid taking a magnesium supplement:
Potential interactions with medication
Examples of drugs that may interact with magnesium supplements include:
- Antacids
- Certain antibiotics and antifungals, such as aminoglycosides and amphotericin B
- Heart medications such as digitalis
- Diuretics
- Proton pump inhibitors
- Some chemotherapy drugs
Stomach surgery, diarrhea and dehydration
Pay attention to the different types of magnesium as well, because some might have more interference with medications than others. For example, don't take magnesium citrate if you've had stomach surgery, have diarrhea or are dehydrated because its laxative effect can make you more dehydrated.
Kidney disease or kidney failure
Don't take magnesium if you have kidney failure. The kidneys filter excess magnesium, so the risk of magnesium imbalance is higher with kidney disease.
Forms of Magnesium
"Magnesium comes in a wide array of different formulations," says Nastasi. "This can include anything from magnesium chloride to magnesium oxide to magnesium threonate. And these have very different absorption abilities within the body."
For example, magnesium citrate is readily absorbed and used in your body, but magnesium glycinate and chelated forms are absorbed better than citrate or lactate forms. Chelated forms of magnesium are easier for your body to absorb because of their molecular structure.
So what's the best form of magnesium? Higher bioavailability is better, because it means your body can absorb more nutrients.
Glycinate
Magnesium glycinate is easily absorbed in the body, and is less likely to have a laxative effect. That's because glycinate is absorbed by a different part of your intestine, in contrast to other types of magnesium.
Citrate
Magnesium citrate is an over-the-counter drug for occasional constipation and acid indigestion. It’s often used as a laxative over other forms of magnesium because it’s gentler and better absorbed in the body.
Malate
Magnesium malate, or the magnesium salt of malic acid, strengthens bones. It also optimizes calcium absorption. Malic acid is widely used in the food and beverage industry for flavor and acidity.
