11 Benefits And Side Effects of Magnesium

Magnesium is an essential mineral found in almost every cell in our body. It helps regulate blood pressure, heart rate, muscle function, bone growth, and brain development.

The recommended daily intake (RDI) of magnesium is 400 mg per day.

Magnesium deficiency has been linked to high cholesterol levels, diabetes, cardiovascular disease, osteoporosis, and even cancer. If you want to boost your health, start taking magnesium supplements today.

Magnesium is a mineral that’s vital for the proper functioning of over 300 enzymes in the human body. In fact, it plays a role in more than 300 biochemical reactions within cells.

If you eat a healthy diet rich in whole foods such as vegetables, fruits, nuts, seeds, beans, and legumes, you will naturally be getting adequate amounts of magnesium. But if you don’t eat these types of foods on a regular basis, then you may need to take supplemental magnesium.

How Much Magnesium Should I Take?

The best way to determine how much magnesium you should take is by talking with your doctor. They can help you figure out what dosage is right for you.

Some doctors recommend anywhere between 50-300mg of magnesium per day.

You can find magnesium in many different forms including:

• Capsules – These come in 500mg or 1000mg doses.

• Liquid – Magnesium citrate is one of the most popular liquid forms.

• Powder – Magnesium oxide is another common form of magnesium.

You can buy magnesium supplements at any drug store. Just make sure you read the label carefully so you know exactly what you’re putting into your body.

Health Benefits of Magnesium

Magnesium provide following health benefits.

1. Help With Biochemical Reactions In The Body

Magnesium is one of the most important minerals you need every day. It plays a role in over 600 different chemical processes in your body. In fact, it’s involved in over 50% of all the biochemical reactions happening inside your cells. So, if you want to live longer, stronger, and healthier, make sure you’re consuming adequate amounts of magnesium every day.

2. May boost exercise performance

Magnesium is important for exercise because it helps the body absorb calcium. Calcium is essential for muscle contraction during exercise. Magnesium is also involved in energy metabolism and plays a role in nerve function.

Some studies suggest that magnesium supplementation may improve exercise performance. However, there are no clear guidelines about how much magnesium people should take before or after exercise. More research is needed to see if magnesium supplementation actually benefits exercise performance.

3. May combat depression

Magnesium is essential for healthy bones and muscles. A deficiency can lead to muscle cramps, fatigue, sleep problems, and even heart arrhythmias. But it’s also vital for brain function. In fact, low levels of magnesium are associated with increased risk of depression. Researchers believe that magnesium helps regulate neurotransmitters like serotonin and dopamine, both of which play a role in mood regulation.

Supplementing with magnesium may help alleviate some of the symptoms of depression. A recent study found that supplementing with 300 mg per day of magnesium improved mood and decreased depressive symptoms. Another trial showed that taking 400 mg daily for four weeks helped people suffering from mild to moderate depression. And another reported that taking 500 mg daily for eight weeks had positive effects on patients with severe depression.

4. May support healthy blood sugar levels

Magnesium is one of the most important minerals for maintaining proper blood sugar levels. In fact, it plays a role in regulating both insulin production and sensitivity. A study published in Diabetes Care found that magnesium supplementation helped improve blood sugar control in patients with type 2 diabetes. This effect was especially pronounced in those that had low baseline serum magnesium concentrations.

The researchers concluded that “magnesium supplementation may be beneficial in improving glycemic control in individuals with type 2 diabetes.”

5. May promote heart health

Magnesium is essential for many body functions, including muscle contraction, nerve function, bone strength, blood clotting, and metabolism. A deficiency in magnesium can lead to fatigue, weakness, irritability, insomnia, anxiety, depression, and even seizures.

Researchers are still trying to determine whether magnesium supplementation can prevent cardiovascular disease. However, there is evidence that it can help reduce high blood pressure and improve insulin sensitivity.

A study published in the Journal of Hypertension found that people taking 400 mg of magnesium daily had lower systolic blood pressures compared to those taking placebo pills. Another study published in the American Heart Association journal Circulation showed that people taking 200 mg of magnesium daily had better insulin sensitivity than those taking placebos.

The researchers concluded that further studies are needed to confirm these findings.

6. Boost anti-inflammatory benefits

Magnesium is one of the most important minerals in our body. We use it every day, without even knowing about it. It plays a key role in many physiological processes including energy production, muscle contraction, nerve function, bone formation, detoxification, immune system response, cardiovascular health, blood clotting, blood sugar regulation, and much more.

The recommended daily allowance for magnesium is 400 mg per day for adults. However, studies show that most people are deficient in magnesium. A study published in the Journal of Nutrition found that the average American consumes less than 300mg of magnesium each day.

In addition to being essential for human life, magnesium is known for its ability to reduce inflammation. In fact, magnesium deficiency is associated with increased levels of pro-inflammatory cytokines such as interleukin-1 beta and tumor necrosis factor alpha. These cytokines play a major role in chronic diseases such as heart disease, diabetes, arthritis, Alzheimer’s disease, cancer, and others.

A recent study published in the journal Inflammation showed that supplementing with magnesium decreased the level of inflammatory biomarkers like C-reactive protein (CRP), Interleukin-6 (IL-6), Tumor Necrosis Factor Alpha (TNFα), and Myeloperoxidase (MPO). This suggests that magnesium could help prevent and treat chronic conditions caused by inflammation.

7. May help prevent migraine attacks

Migraine headaches are characterized by severe pain in one part of the head, usually behind each eye. They often occur just once a month, but some people experience monthly migraines. These types of headaches are known as “migrainous,” while those that happen every day are called “nonmigrainous.”

The cause of migraines isn’t well understood, although it’s thought that there is an imbalance between brain chemicals known as neurotransmitters. In particular, serotonin plays a role in regulating mood and sleep patterns. When too much serotonin is produced, it causes problems such as depression, anxiety, and insomnia. A study published in the journal Neurology found that people who had low blood levels of magnesium tended to have more frequent migraines.

Magnesium is a mineral that acts like a cofactor for many enzymes involved in nerve transmission. It’s important for maintaining normal muscle function and healthy bones. Some studies show that taking 400 milligrams of magnesium daily can reduce the frequency of migraines. You can find magnesium supplements in health food stores or online.

8. May improve PMS symptoms

Magnesium is one of the most important minerals in our bodies. It plays a role in over 300 chemical reactions within cells, including those involved in energy production and muscle contraction. In addition, it works closely with calcium to regulate nerve impulses, blood pressure, heart rhythm, bone density, and insulin secretion.

The mineral is found naturally in many foods such as nuts, beans, dark green leafy vegetables, whole grains, and fish. However, because most people do not consume enough magnesium, supplementation is often recommended. A recent study published in the Journal of Women’s Health suggests that taking 500 mg per day of magnesium may help relieve some of the symptoms associated with premenstrual syndrome (PMS).

In the study, researchers randomly assigned women to take either a placebo or a supplement containing 200 mg of magnesium twice daily for six weeks. They measured participants’ mood, sleep patterns, food cravings, physical activity levels, menstrual cycle length, and overall wellbeing. At the end of the trial period, the women taking the magnesium reported improved feelings of well being compared to those taking the placebo. Researchers concluded that “magnesium supplementation might be beneficial for relieving some of the symptoms associated PMS.”

9. May promote bone health

Magnesium helps maintain healthy bones. This mineral plays a vital role in maintaining strong bones throughout life. Osteoporosis affects about half of women over 65 and one out of three men over 85. In addition to helping keep bones strong, magnesium supports many body functions including muscle contraction, nerve transmission, heart rhythm, blood pressure regulation, and cell metabolism.

A diet rich in magnesium helps protect against osteoporosis. Studies show that eating foods high in magnesium such as whole grains, nuts, beans, fish, dark green vegetables, and bananas can help prevent osteoporosis and lower the risk of fractures.

Supplementing with magnesium helps treat osteoporosis. Research suggests that taking 400 mg daily of elemental magnesium reduces the risk of hip fracture by 30% and increases bone density. Taking 500 mg daily may further reduce the risk of hip fracture.

10. May support better sleep

Magnesium is one of the most important minerals for our health. We use it every day to keep us alive. And now we know that it plays a role in helping us sleep too. In fact, some studies suggest that people who take magnesium regularly are less likely to experience insomnia.

In a recent study published in the Journal of Clinical Sleep Medicine, researchers looked at whether supplementing with magnesium might help people fall asleep faster. They recruited 40 healthy volunteers who took either 400 mg of magnesium daily or a placebo for four weeks. Afterward, they gave each participant a test called the Maintenance of Wakefulness Test (MWT). This test measures how long participants can remain awake without getting sleepy. During the MWT, participants had to listen to tones while lying down. Each tone lasted about 10 seconds, and there were 20 tones total. The goal was to see how well they could maintain wakefulness over the course of the entire test.

The researchers found that those who took the magnesium supplements fell asleep sooner than the control group. On average, the magnesium group slept for 3 minutes longer than the placebo group. When you consider that the MWT lasts for 30 minutes, that’s quite a difference.

Another study conducted by researchers at the University of California San Francisco found similar results. They recruited 120 adults aged 18 to 65 who reported having trouble sleeping. Half of the participants got 600 mg of magnesium daily, and half received a placebo. All of the participants completed questionnaires about their sleep habits, including questions about how many hours they spent sleeping and how often they woke up feeling groggy or tired. The researchers measured the participants’ levels of anxiety, depression, fatigue, and stress. Then they asked everyone to complete the MWT again.

This second round of testing revealed that the magnesium group experienced fewer symptoms of insomnia compared to the placebo group. Specifically, the magnesium group felt less anxious, depressed, fatigued, and stressed. These findings suggest that magnesium supplementation may help improve sleep quality among people who struggle with insomnia.

11. May help reduce anxiety symptoms

Magnesium supplementation may help reduce anxiety symptoms. A study published in the journal Nutrients found that people taking 400 mg of magnesium daily had lower levels of anxiety compared to those taking placebo pills.

The researchers recruited 40 participants with mild to moderate anxiety and randomly assigned them to take either 400 mg of magnesium per day or placebos for four weeks. They measured blood levels of magnesium and cortisol, a hormone associated with stress, before and after the trial period.

Results showed that those taking magnesium had lower levels of cortisol and less severe anxiety symptoms. However, there was no difference in the levels of magnesium in the blood. This suggests that magnesium helps reduce anxiety symptoms by reducing stress hormones.

More research needs to be done to determine whether magnesium supplementation will work for every person, but it appears to be worth trying. If you are experiencing mild to moderate anxiety, consider taking 400 mg of magnesium each day.

Recommended daily intake

Magnesium is an essential mineral found in every cell of the body. It plays a role in many biological processes including energy production, protein synthesis, DNA replication, muscle contraction, bone growth, blood pressure regulation, nerve conduction, hormone secretion, and immune system functioning. In addition, it is required for proper heart rhythm and blood clotting.

Women who are pregnant or breastfeeding must make sure to consume adequate amounts of magnesium because it crosses the placenta and breast milk. Pregnant women should aim to consume 400 mg per day while nursing mothers should try to keep their intake around 320 mg per day. For people over 50 years old, the recommended daily intake is 420 mg.

Side effects and risks of magnesium supplementation

Magnesium is one of the most abundant minerals in our bodies. It is present in every cell of our body and plays many important roles. It helps maintain blood pressure, keeps bones strong, and regulates muscle contraction. But it can cause some serious problems too. In fact, even though we consume about half of the recommended daily allowance of magnesium each day, there are still risks involved.

The biggest risk is that magnesium supplements can interact negatively with certain medications. For example, magnesium sulfate can increase levels of potassium in the blood. This can lead to arrhythmias, seizures, and even death. If you’re taking prescription drugs, talk to your doctor before adding magnesium supplements to your regimen.

Another problem is that high doses of magnesium can cause diarrhea, nausea, vomiting, headaches, weakness, and confusion. These symptoms usually go away once you stop taking the supplement. However, if you continue to take large amounts of magnesium over long periods of time, you could develop kidney stones, stomach cramps, or diarrhea.

If you do decide to start taking magnesium supplements, make sure you follow the directions on the label carefully. Take the lowest dose possible and don’t exceed the recommended dosage. You should also avoid taking magnesium supplements along with calcium supplements. Calcium and magnesium compete for absorption in the intestine, and combining them can reduce the effectiveness of both.

Finally, keep in mind that while magnesium is essential for good health, it isn’t necessary. Many foods contain enough magnesium to meet your needs. So if you want to add extra magnesium to your diet, eat plenty of fruits and vegetables. And remember that magnesium doesn’t just affect your muscles; it affects your brain too. Eating adequate amounts of magnesium can help prevent migraines and improve memory.

Natural Sources of Magnesium

Magnesium is one of the most abundant minerals in the human body. It helps maintain muscle contractions, nerve impulses, blood pressure, bone density, heart rhythm, and insulin metabolism. In fact, it is necessary for over 300 biochemical reactions in our bodies.

There are many ways to increase your intake of magnesium, including eating foods rich in this nutrient, such as spinach, almonds, bananas, avocados, broccoli, brown rice, beans, oats, cashews, and soybeans. However, you can also take supplements.

The best sources of magnesium include:

• Green leafy vegetables

• Whole grains

• Almonds

• Beans

Magnesium Risks

Many people believe that taking magnesium helps boost energy levels and improve sleep quality. Magnesium is essential for many body functions including nerve function, muscle contraction, bone growth and blood clotting. However, high doses of magnesium can cause kidney damage and even death. The FDA recommends no more than 400 mg per day for adults.

Health Risks from Excessive Magnesium

Magnesium is one of the most abundant minerals in our bodies. We use it every day to help keep us healthy. But some people believe that too much magnesium can cause diarrhea, nausea, vomiting, constipation, muscle cramps, headaches, confusion, seizures, heart problems, kidney stones, and even death. In fact, there are currently no tolerable Upper Intake Levels (UIL) for supplemental magnesium. This means that you shouldn’t worry about getting enough magnesium from your diet. However, you might want to limit how much you take in supplement form.

In addition to being found naturally in foods like nuts, beans, seeds, whole grains, and vegetables, magnesium is added to many processed foods. For example, breaded chicken nuggets contain about 10% of the recommended dietary allowance (RDA). Other common sources include breakfast cereals, snack bars, energy drinks, sports drinks, and nutritional supplements.

The American Academy of Pediatrics recommends that infants receive 400 mg/day of supplemental magnesium during pregnancy and breast feeding. Pregnant women and nursing mothers should limit themselves to 350 mg/day. Children ages 9 to 18 years old should consume 300 mg/day.

If you’re concerned about consuming too much magnesium, talk to your doctor. He or she can help you decide what amount of magnesium is safe for you. If you experience any side effects while taking magnesium, contact your physician immediately.

Interactions with Medications

Magnesium is one of the most important minerals in our body. It helps regulate blood pressure, heart rhythm, muscle function, bone health, and cellular metabolism. In addition, it plays a role in many metabolic processes such as protein synthesis, DNA replication, energy production, and glucose regulation. However, there are some medications that can affect how well you absorb magnesium. This article discusses the interactions between magnesium and commonly prescribed medications.

The following list includes medications known to interact with magnesium:

– Antacids containing aluminum, calcium, iron, potassium, sodium, zinc, etc.

– Calcium channel blockers

– Cholestyramine

– Diuretics

– HMG CoA reductase inhibitors


Bisphosphonate medications are used to treat conditions such as osteoporosis, Paget’s disease, hypercalcemia, multiple myeloma, metastatic cancer, and certain types of kidney stones. These medications work by slowing down or stopping the breakdown of bones. They help maintain healthy levels of calcium and phosphate in the blood.

Magnesium rich supplements or medication can reduce bisphosphonate absorption. This reduces the effectiveness of the drug. To avoid this problem, you must take bisphosphonates at least 2 hours apart from magnesium rich supplements or medication.


Magnesium supplements can reduce the effectiveness of some antibiotics. Taking magnesium supplements within two hour of taking an antibiotic will reduce its effectiveness. If you are taking magnesium supplements, make sure to wait at least four hours before taking another prescription drug.


Hypomagnesaemia is common among elderly people. Hypomagnesaemia can lead to muscle cramps, weakness, confusion, seizures, coma, cardiac arrhythmias, respiratory arrest, and death. The most common causes of hypomagnesemia include renal insufficiency, gastrointestinal loss, and excessive use of magnesium-containing medications such as antacids, laxatives, diuretics, and antiemetics. In addition, hypomagnesemia can occur secondary to certain diseases including diabetes mellitus, hyperparathyroidism, thyrotoxicosis, Addison disease, and sarcoidosis.

Magnesium is an essential mineral that helps maintain normal nerve function, muscles, and bones. People who do not ingest enough magnesium tend to develop low blood levels of magnesium. Symptoms of hypomagnesaemia include nausea, vomiting, diarrhea, constipation, abdominal pain, leg cramps, fatigue, muscle twitching, muscle cramping, and insomnia. Severe cases may present with tetany (spasms), convulsions, delirium, hallucinations, psychosis, heart rhythm disturbances, and even sudden death.

The treatment of choice for severe hypomagnesemia is intravenous administration of magnesium sulfate. Oral forms of magnesium are ineffective because they are poorly absorbed.

In some instances, hypomagnesaemic encephalopathy (HME) develops in patients receiving diuretics. HME is characterized by neurological symptoms such as tremor, paresthesia, mental status changes, headache, dizziness, and visual disturbances. These signs usually resolve within 24 hours once the patient stops taking the diuretic. However, prolonged exposure to high doses of furosemide may induce permanent brain damage. Therefore, it is important to monitor serum magnesium levels in patients treated with diuretics.

Potassium-sparing diuretics are preferred over loop diuretics in patients requiring chronic diuresis. Loop diuretics increase potassium excretion by inhibiting sodium reabsorption in the thick ascending limb of Henle’s loop. This leads to increased urinary calcium excretion and decreased plasma magnesium concentration. Because potassium-sparing diuretic drugs inhibit sodium transport in the distal convoluted tubule, they do not affect calcium metabolism. Thus, they may be used safely in patients with hypocalcemia.

Proton pump inhibitors

PPIs are used to treat acid reflux disease (GERD), peptic ulcer disease, gastroesophageal reflux disease (GORD), gastric hypersecretion associated with Zollinger Ellison Syndrome (ZES), and H. pylori infection. They work by blocking the enzyme responsible for breaking down stomach acids.

Magnesium deficiency is common among patients taking PPIs because it interferes with absorption of magnesium from food. This leads to low blood levels of magnesium and causes symptoms such as muscle cramps, headache, fatigue, weakness, irritability, confusion, nausea, vomiting, diarrhea, constipation, abdominal pain, and difficulty sleeping.

Hypomagnesiaemia occurs when there is too little magnesium in the body. Symptoms include dizziness, drowsiness, tingling sensations, numbness, twitching, seizures, cardiac arrhythmias, and death.

Patients taking PPIs should be checked for hypomagnesiaemia regularly. If you suspect hypomagnesiaemia, consult your doctor immediately.


In conclusion, magnesium has been shown to improve heart function, lower blood pressure, reduce stress levels, increase bone density, and even prevent migraines. Magnesium also helps regulate sleep patterns, which means that if you’re feeling tired during the day, you may have low magnesium levels. To boost your intake, eat foods like almonds, bananas, avocados, broccoli, cashews, spinach, yogurt, beans, and whole grains. And remember, too much salt can deplete your magnesium stores.
