  • Frequently Asked Questions




What Is Magnesium?



Magnesium is an essential mineral, meaning you need to take it in through your diet because your body cannot produce it on its own. After calcium, sodium, and potassium, it is your body’s fourth most common mineral. About 50 to 60 percent of magnesium gets stored in your bones, and the rest is in your soft tissues and muscles. (1)(2)





What Does Magnesium Do?



Magnesium plays an important role in over 300 of your body’s enzyme systems. These systems are responsible for multiple processes, including energy production, protein synthesis, muscle and nerve function, and regulating blood pressure and blood sugar. (1)(2)





In your heart, magnesium helps transport calcium and potassium. This transport affects your heart health, nervous system, muscles, and nerves. Magnesium (and calcium) also contribute to your bone health and development. Because of these important functions, magnesium deficiency has been linked with a higher risk of cardiovascular disease and osteoporosis. (1)(2)

Magnesium helps with energy production by directly affecting your body’s ability to undergo ATP (adenosine trisphosphate) metabolism. It also impacts oxidative phosphorylation and glycolysis. These three processes together help your cells generate ATP for energy. (1)





You’re probably familiar with ATP as a strength athlete — it’s known as “the energy currency of the cell.” ATP is at play when you do short-duration, high-intensity training like weightlifting or sprint workouts. Magnesium also contributes to muscle contraction. (1)





How Much Magnesium Do I Need?



About 56 to 68 percent of Americans do not reach the recommended daily allowance (RDA) of magnesium through their diets. The United States Food and Nutrition Board lists the RDA for magnesium as 420 milligrams for adult cisgender men and 320 milligrams for adult cisgender women. (4)





Low levels of magnesium can lead to chronic health conditions and a lack of energy. Factors like a low-nutrient diet, alcohol intake, cigarette use, and gastrointestinal disorders can lead to low amounts of magnesium. Certain medications like antacids, antibiotics, blood pressure drugs, diuretics, and proton pump inhibitors can also reduce your magnesium levels. (1)





Sources of Magnesium



You can boost your intake of magnesium through food sources and dietary supplements. Nutritionists and dietitians typically recommend reaching your nutrient intake through food first and adding supplements as a boost. Always check with a qualified healthcare provider before trying a new supplement to help determine the right one.

Benefits of Magnesium



Magnesium is essential to several systems in your body. Keeping your magnesium levels high can help with athletic performance, improve sleep, boost bone health, and help prevent migraine headaches. Due to its critical role in your heart, magnesium can help regulate your blood pressure and blood sugar levels, improving your heart health.





May Improve Athletic Performance



Researchers have investigated whether magnesium can be an ergogenic aid to athletes to improve exercise performance. Magnesium is crucial for energy production and storage, healthy nerve function, muscle contractions, and protein synthesis. Many athletes do not get enough magnesium, and if they struggle in some of these areas, it could be the culprit. (5)





Older athletes may particularly benefit from getting magnesium. Some studies show a positive correlation between high magnesium levels in older adults and strength, power, and muscle performance. (6)





There is a popular claim that magnesium supplementation can help ease muscle cramps. However, a 2020 review of studies and many others found no link between magnesium and reducing muscle cramps. (7)

Research shows that magnesium may help reduce delayed onset muscle soreness but not cramps. A study was done on college students training the bench press while supplementing with magnesium. One group took magnesium, and the other took a placebo. They reported their level of soreness 24, 36, and 48 hours after their bench press session. The magnesium group reported decreased muscle soreness after 48 hours, and the placebo group didn’t report any change. (8)





Getting enough magnesium may help improve muscle recovery, potentially leading to better athletic performance over time.





May Improve Sleep



You have probably heard that taking magnesium at night may help improve your sleep — here’s how it may work. Magnesium contributes to healthy nerve function, potentially reducing stress and improving sleep. (9)





Magnesium plays a role in regulating the glutamatergic and gamma-aminobutyric acid (GABA) systems. GABA is an amino acid that functions as a neurotransmitter that inhibits the excitement of your central nervous system. Magnesium binds to GABA and helps calm your nervous system, potentially leading to better sleep. (9)(10)

It may also work in two additional ways. Since magnesium transports calcium, it can help reduce calcium concentration in your muscle cells, leading to muscle relaxation. Studies show magnesium may also help reduce the concentration of the stress hormone cortisol. Relaxed muscles and reduced stress can both lead to better sleep. (9)





Studies suggest that magnesium intake is associated with better sleep quality and reaching the recommended amount of sleep — seven to nine hours. A study in rats also suggests that magnesium can increase melatonin production. Melatonin is a hormone that helps regulate your sleep and wake cycle. (9)





May Help Prevent Migraine Headaches



Low levels of magnesium have been linked with chronic migraine headaches. Getting enough magnesium may be a helpful complementary treatment for preventing and managing migraine headaches. (11)





A 12-week study was done on four groups with a history of migraine headaches. One group took 500 milligrams of magnesium oxide per day. One group took 500 milligrams of L-carnitine (an amino acid) daily. One group took 500 milligrams of magnesium oxide and 500 milligrams of L-carnitine. The fourth group took a placebo. All groups reported some reduced migraine symptoms, but the magnesium group had a significant reduction in all migraine headache indicators. (11)





Improves Bone Health



About 60 percent of your body’s magnesium gets stored in your bones, so it makes sense that getting enough magnesium can impact your bone health. (2)





Research shows that low magnesium levels correlate with low bone mineral density in pre and postmenopausal people. Conversely, a higher intake of magnesium positively correlates with higher bone mineral density in people of all ages and genders. (4)





Osteoporosis is a condition where you lose bone mineral density and bone mass as you age, increasing your risk of fractures. Cisgender women are more likely to develop osteoporosis. Research shows supplementing with magnesium improves bone mineral density in people with osteoporosis, reducing their risk of fractures. Evidence also links a high intake of magnesium with a lower risk of fractures for older adults of all genders. (4)

In a review of multiple studies from 2009 to 2021, the correlations between high magnesium intake and high bone mineral density and the link between low magnesium levels and osteoporosis were repeatedly found. (12)





For older adults with a high risk of osteoporosis, it’s important to pack your diet with foods rich in magnesium, vitamin D, calcium, and protein. Medical professionals also recommend weight-bearing cardio exercise and resistance training for long-lasting bone health. (13)





Boosts Heart Health



One of magnesium’s essential functions is transporting calcium through your heart vessels, which prevents calcium buildup in your arteries. Evidence links magnesium deficiency with an increased risk of heart disease. (1)





Arteriosclerosis is a health condition where your arteries become thick and hardened, preventing the delivery of oxygen and blood through the rest of your body. Getting enough magnesium can help keep your arteries clear by moving the calcium along. (1)

Low magnesium levels can contribute to an irregular heartbeat and increase your risk of heart failure, stroke, and other cardiovascular diseases. (4)





May Help Regulate Blood Pressure



Magnesium may help regulate your blood pressure due to calcium transport and because magnesium increases nitric oxide production in your body. Nitric oxide increases vasodilation — the widening and relaxing of your blood vessels. Better vasodilation improves your blood flow and can lower your blood pressure. (14)(15)

Although magnesium helps regulate blood pressure, studies show that magnesium supplements alone are not enough to help treat high blood pressure or hypertension. Medical professionals recommend increasing magnesium and potassium while lowering dietary sodium and eating a healthy diet packed with fruits and vegetables. (16)





May Help Regulate Blood Sugar Levels



Magnesium plays a role in metabolizing blood sugar (glucose). Low magnesium levels have been linked with high blood sugar and insulin resistance, which can put you at a higher risk for type 2 diabetes. Getting enough magnesium may improve insulin sensitivity, regulate blood sugar levels, and lower your risk of type 2 diabetes. (2)(4)
