Magnesium
articles
You’re familiar with the vitamin and mineral superstars, like Vitamin D and Calcium, but you might not be as familiar with another key nutrient—Magnesium. Did you know, for example, that Magnesium is the fourth most abundant mineral in the human body? Or that it plays a key role in many bodily functions?
While you can get Magnesium from a variety of food sources (ranging from whole grains and dark green leafy vegetables to nuts and beans), you can also get it from dietary supplements.
You might be surprised to learn that there are different forms of Magnesium and that some forms of Magnesium are more easily absorbed by the body. Read to learn more about the various types of Magnesium and what they’re used for.
Commonly identified as an electrolyte, Magnesium is touted for its role in maintaining mineral balance because it works hand-in-hand with Calcium. In fact, 50 to 60% of Magnesium is stored in our bones, while the rest is stored in blood, cells, and tissues.[1]
However, it is estimated that 10-30% of people have a Magnesium deficiency and 54% of the U.S. population consumes less than the recommended amount of Magnesium from their diet alone.[1,8] That’s more than ½ of the U.S. population!
As a key nutrient vital to good health, Magnesium is an essential mineral the body requires for more than 300 enzymatic reactions.[2] It delivers a variety of health benefits, including the following: [2,3,4]
Since dietary supplements can help fill innutrition gaps, you might be thinking about taking a Magnesium supplement. But since Magnesium exists in multiple forms, you might be wondering, “What type of Magnesium should I take?” It really depends on your individual needs and health goals. Let’s break down the different types of Magnesium.
This is one of the most common types of Magnesium, and this form of magnesium is highly bioavailable, which means it’s easier for the body to absorb. Magnesium Citrate is chelated form of Magnesium. Chelated forms of Magnesium have special molecular bonds to other organic compounds, in this case citric acid, which make them more stable and allow them to be better absorbed in the body than some other forms of Magnesium, such as Magnesium Oxide.[5] It’s a good choice if you want to increase your magnesium levels.
Another one of the chelated forms of Magnesium is Magnesium Glycinate (sometimes called Magnesium Bisglycinate), which is elemental magnesium bound with glycine (an amino acid). It’s also better absorbed by the body than other Magnesium forms such as Magnesium Oxide and Magnesium Glycinate is gentle on the stomach.†
Magnesium Oxide is a Magnesium salt that consists of Magnesium and oxygen ions. Magnesium Oxide is commonly found in multivitamins and is generally less expensive than chelated forms of magnesium, but may cause some individuals to experience gastrointestinal issues.
Magnesium Malate is is elemental magnesium combined with malic acid . This form of magnesium is also chelated, which again means it is better absorbed than non-chelated forms, and therefore has higher bioavailability. At Nature Made, Magnesium Malate is commonly found in a Magnesium Complex, which is great for those seeking multiple forms of Magnesium in one product. [7]
As another type of Magnesium salt, Magnesium Chloride contains chlorine. The body absorbs this form more easily than some other forms, which is why it is often used in capsules and tablets to help Magnesium intake.[9]
If you’ve ever taken an Epsom salt bath, then you’re familiar with Magnesium Sulfate. When Magnesium, sulfur, and oxygen combine, they form Magnesium Sulfate, which looks similar to table salt. Instead, it’s often used to relax muscles to help relieve stress. As a salt, it can be dissolved in bathwater, but it’s also added to topical treatments, such as Magnesium oil and body lotions.
When Magnesium binds with lactic acid (naturally produced by your muscle and blood cells), it forms a salt called Magnesium Lactate. It’s often added to fortify foods with Magnesium.
Additional types of Magnesium exist as well, including:
Both are common types of Magnesium that are highly bioavailable and can be easily absorbed by the body. Typically, Magnesium Glycinate is gentle on the stomach, which is why some people prefer supplements with this form. Talk with your doctor or primary healthcare physician to help determine which supplemental magnesium works best for you.
The Recommended Dietary Allowance (RDA) for Magnesium varies, but in general, most adult women need 310-320 mg/day and most adult men need 400-420 mg/day.[4]
It’s unlikely that you’ll consume too much Magnesium from food, especially since your kidneys get rid of any excess through the urine.
However, it’s possible to get too much Magnesium from high doses of supplements or medications. .[2] And Magnesium toxicity can occur from taking mega-doses of antacids or laxatives (typically containing more than 5,000 mg/day Magnesium). .[2]
While eating a healthy, balanced diet would ideally provide the nutrients our bodies need, supplements can help close the nutrient gaps and approximately 54% of us are not eating enough Magnesium from food alone. Whether you need a Magnesium supplement or another dietary supplement, look to a trusted brand that uses quality ingredients. Since 1971, Nature Made has relied on research to serve as the foundation for our high-quality, science-backed products.
Magnesium plays an important role in more than 300 enzymatic reactions and provides a variety of health benefits ranging from supporting muscle relaxation to supporting heart health to converting food into cellular energy. Many kinds of Magnesium exist, such as Magnesium Citrate, Magnesium Glycinate, and Magnesium Oxide. The body more easily absorbs certain types of Magnesium better than others. Magnesium benefits include supporting essential muscle and heart function, supporting nerve function, and helping to support bone and teeth health. Magnesium also helps relax the body. The best magnesium supplement really depends on what you’re using it for. Whether you’re considering a Calcium Magnesium supplement or Magnesium Glycinate capsules, always talk with your doctor to discuss which supplement would best meet your needs.†
