Magnesium is a hardworking mineral that assists in over 300 enzyme functions in your body. It contributes to the proper functioning of your bones, muscles, nerves and mood, amongst others. Unfortunately, it is estimated that between 50%1 and 75%2 of Americans do not get enough from their usual daily diet. The rise of processed foods, intensive agricultural practices that have decreased magnesium in the soil and even health conditions such as celiac disease can contribute to low magnesium levels.

Yet, it can be difficult to diagnose a magnesium deficiency because your body stores most of it in your bones and the rest in your tissues. Therefore, blood tests are not accurate in measuring magnesium in your body.3 Plus, low magnesium symptoms are not easy to identify because they resemble other conditions like tiredness or irritability.

Eating foods high in magnesium can benefit your health because of magnesium’s many contributions to your body’s essential functions. In some cases, a magnesium citrate supplement can also help you achieve an optimal daily dose if you’re not getting enough through your diet. There are various reasons why your diet may lack magnesium, but there are easy measures you can take to boost your levels.

What is Magnesium?

Magnesium is a chemical element with the symbol “Mg” and atomic number 12. It is a shiny gray solid and belongs to the alkaline earth metals group on the periodic table. Magnesium is abundant in the Earth’s crust and is the ninth most abundant element by mass.

The importance of magnesium in your body’s daily processes cannot be overstated. Magnesium is present in around 80% of metabolic functions, including energy production, DNA synthesis, muscle contraction, nerve function and regulation of blood pressure. But this mineral is still poorly understood in scientific communities as opposed to other micronutrients like calcium or iron.4 One of the reasons is the difficulty in determining magnesium deficiency in clinical testing.

Magnesium Benefits

Having optimal magnesium levels can benefit your body and mind in a surprising number of ways.

Prevention of Migraines icon

Prevention of Migraines

Magnesium can help as a complimentary treatment to prevent the onset of migraines, especially migraines with aura.5 Magnesium oxide, taken as an oral supplement, may soothe inflammation that triggers migraines.6

Stronger Bones icon

Stronger Bones

Higher amounts of magnesium translate into higher mineral bone density, which could lower risk of fractures.7 This finding is especially interesting as a potential preventative treatment like osteoporosis, though more research is needed.8

Stress Management icon

Stress Management

When you’re stressed, your body loses magnesium at a quicker rate, which can lead to a deficiency.9 A magnesium deficiency, in turn, can increase your susceptibility irritability and mild anxiety.10 Making sure you get enough magnesium can improve your body’s ability to cope and prevent the vicious cycle of stress.

Improved Heart Health icon

Improved Heart Health

High magnesium intake improves the processing of glucose and insulin. This lowers the risk of diabetes, hypertension, stroke and cardiovascular diseases.11 Magnesium also helps transport electrolytes like calcium and potassium, which are essential to produce normal heartbeats.12

The Science-Backed Benefits of Magnesium

Learn more about the science-backed benefits of magnesium. Although the benefits of magnesium are many, it remains a difficult mineral to study in clinical trials. However, recent promising scientific research continues to make important discoveries on its impact on our health.

Magnesium may improve memory, according to a clinical study based on healthy Chinese adults.13 Researchers issued a standard memory test to participants and observed that those who had received magnesium supplements showed significant improvement over the control group. Additionally, older participants performed better than the younger ones. This study shows magnesium’s ability to positively affect brain function and neuron activity.

Another interesting recent research project discovered that magnesium microneedling patches improve under-eye wrinkles.14 Microneedling is a common procedure used for the treatment of skin conditions like wrinkles and acne scars. It is available as a convenient at-home beauty treatment. Clinicians determined there was a significant improvement in wrinkles after 12 weeks of treatment. The non-absorbable magnesium microneedling patches offered effective results with minimum discomfort.

Magnesium oxide is made by combining magnesium with oxygen. It is readily available at most pharmacies as capsules or powders. Magnesium oxide is generally used to treat heartburn, indigestion or as a short-term solution to occasional constipation?15 It is not absorbed by the body well, so won’t substantially improve magnesium levels.16

Magnesium Citrate

Magnesium citrate supplements are also commonly found in pharmacies or online. Magnesium citrate is easy to take orally, as a supplement or as a powder that you dissolve in water or juice. It can be used to boost magnesium levels and contribute to better sleep. In high doses, it can have a laxative effect.17

Magnesium Malate

Magnesium malate combines magnesium with malic acid, an organic compound that you find in certain foods. This supplement can help boost energy, athletic performance and skin health.18 Although this supplement is generally well tolerated, it can have adverse side effects when taken with medications like diuretics or antibiotics. Speak to your healthcare practitioner if you have any concerns or questions.

Magnesium Lactate

Magnesium lactate is the resulting salt formed from magnesium binding with lactic acid. It is not generally popular as an over-the-counter supplement. However, due to its easy absorption in the digestive tract, it may be a good option for people who need to take high doses of magnesium and cannot tolerate other forms.19

Magnesium Sulfate

Magnesium Sulfate is available at the pharmacy as a short-term treatment for occasional constipation. It can also be used externally as a soaking solution for muscle or joint discomfort.20 You may recognize it as Epsom salts at your local drugstore. Today, there isn’t enough data to support the claim that using a magnesium soak will raise your body’s magnesium levels.21

Choosing the best magnesium supplement depends on various factors, including your specific health needs, preferences and any existing medical conditions. Are you looking to address a magnesium deficiency? Support bone health? Or do you want to improve your sleep? Your goals will help guide your choice. Before starting any new supplement, especially if you have underlying health conditions or are taking medications, consult your healthcare provider. They can help you determine the appropriate supplement and dosage for you.
