Magnesium
articles
As the fourth most abundant mineral in the human body, Magnesium is one of the most multifunctional minerals as it plays a key role in over 300 reactions throughout the body. In fact, 50 to 60% of Magnesium is stored in our bones, 1% is found in our blood, and the rest is stored in cells and tissues. [1] Despite Magnesium’s abundance and importance, a Magnesium shortfall is common, as 54% (that’s over ½) of the U.S. population consumes less than the required amount of magnesium from food. [1]†
Since dietary supplements can help fill in nutrition shortfalls, many people turn to Magnesium supplementation.†
But you may not know that Magnesium exists in multiple forms, including the following:
Regardless of form, the magnesium molecule attaches to another molecule, and this can impact how the nutrient works. [2] The form can affect Magnesium’s bioavailability, which means how easy it is for your body to use.
With so many different forms of this nutrient, let’s look at the difference between two common forms (Magnesium Glycinate vs Citrate) and how they’re absorbed into your body.
Since your body can’t naturally produce minerals, you need to get them through your diet. According to the USDA National Nutrient Database, magnesium-rich foods include rice bran, molasses, pumpkin seeds, seaweed, basil, black beans, and almonds.[3]
As a key nutrient vital to good health, Magnesium is an essential mineral required for more than 300 enzymatic reactions in the body. [4] Magnesium supplementation may help increase your intake of this mineral if you do not consume enough magnesium-rich food in your diet, though you will first want to consult with your healthcare practitioner before adding any new supplement to your daily routine. Here are some benefits of Magnesium:
Magnesium works as an electrical conductor, helping to contract and relax muscles and aids in maintaining a normal heart function. [5]†
The body needs Magnesium for protein synthesis, muscle, and nerve function. [4]†
In order to produce energy, the body needs Magnesium to help metabolize carbohydrates and fats in the foods you eat. [6]†
Magnesium contributes to the structural development of bone. [4]†
Chelates are minerals that are bound to amino acids to improve the minerals stability and remain neutral in solution. The remaining neutral, mineral chelates reduce the binding of dietary components and are therefore better absorbed than their non-chelated forms. As a form that’s easily absorbed by the body, Magnesium chelates are used as magnesium supplements to improve absorption and help to maintain adequate Magnesium levels in the body. [7] Thanks to being more water soluble than inorganic Magnesium forms, organic forms provide better absorption.
Two common forms of chelated Magnesium include Magnesium Citrate and Magnesium Glycinate. But what’s the difference between Magnesium Citrate and Glycinate?
This is a common formulation of chelated Magnesium, and it’s a highly bioavailable form of this key mineral. While there is a difference between Magnesium Citrate and Glycinate (described below), they’re both easily absorbed by the body.
Technically, Magnesium Citrate is composed of Magnesium salt of citric acid. It’s bound with citric acid rather than with a mineral like chloride or oxygen. This allows Magnesium citrate to be better absorbed than magnesium oxide. [8]
As another common form of chelated Magnesium, this form is also highly bioavailable. Created from elemental magnesium and glycine (an amino acid), Magnesium Glycinate is also easily absorbed by the body. Because it’s well tolerated, Magnesium Glycinate is gentle on the stomach.
Because both of these Magnesium forms are more bioavailable than some other forms, they can be good ways to help increase your Magnesium intake.
Which is the best Magnesium supplement? It really depends on your specific health needs and circumstances. For instance, if you want a form of Magnesium that’s gentle on the stomach, you might choose Magnesium Glycinate. If you’d prefer a form with high absorption, you might choose Magnesium Citrate.†
Supplements can help fill in any nutrient gaps to support your health and well-being. Start by talking to your healthcare provider about which supplements may help you meet your individual needs and health goals. When choosing a dietary supplement, whether it’s a Magnesium supplement or something else, look for high-quality supplements with responsibly sourced ingredients. With a trusted brand like Nature Made, we’ve got decades of research as the foundation of our high-quality, science-backed products—and we’ve been an industry leader since 1971. †
As an essential mineral, Magnesium is needed for more than 300 enzymatic reactions in the body. This abundant mineral is available in multiple forms, which can affect how different types of Magnesium work in the body and their ease of magnesium absorption. Magnesium supplements often include Magnesium Glycinate or Magnesium Citrate because they’re highly bioavailable forms. Wondering what’s better—Magnesium Citrate vs Magnesium Glycinate? It really depends on your specific health needs , so talk with your doctor about which one might be right for you.†
