Magnesium is the unsung hero in your body’s daily grind, handling energy, relaxation, digestion, and balance without fanfare—until it’s gone. Suddenly, you’re running on empty, your brain feels like sludge, and muscle cramps hit out of nowhere. Ready to make up for lost time and support your body’s quiet champion? Here’s everything you need to know to take magnesium supplements.

Let’s talk about magnesium—the most underrated member of your body’s health team.

It’s the friend who always shows up early, stays late, and does the dirty work no one else wants to handle.

But what do we do? We totally ignore it until things go sideways.

Then suddenly, your muscles cramp, your energy dips, and you’ve got brain fog that feels like the early stages of zombiehood.

Here’s the thing—your body is always healing.

It’s constantly trying to keep you alive (thank you, body), but it needs a little help.

And magnesium is one of those lifelines.

The sad truth? Thanks to modern farming practices, stress, and less-than-stellar eating habits, most of us aren’t getting enough.

But this sucks-yet-fixable situation can turn around faster than you think.

Keep reading to learn about what magnesium does in the body, why people are deficient, the different types of magnesium and their uses, what to avoid in a supplement, and a list of my favorite magnesium supplements to save you the time and stress of trying to figure it all out.

Key Takeaways

• Magnesium is crucial for health.
• Most of us are deficient in magnesium.
• Magnesium deficiency is fixable – and I’ll share my favorite supplements to get you started.

Why Magnesium Is Important

Magnesium is a powerhouse mineral that supports key functions in your body. It aids energy production, supports bone strength, and helps maintain a stable heart rhythm.

Magnesium’s Role In The Body

Magnesium is the fourth most abundant element in the human body (after calcium, potassium, and sodium), but where do you find it? (1)

• Bone – 50-65%
• Soft tissues, muscles, and organs – 34-39%
• Blood – 1-2% (this is why blood tests don’t effectively measure magnesium levels.)

Magnesium supports virtually every essential body function, helping with digestion, sleep, brain health, and keeping minerals balanced.

It’s used in over 600 enzymatic reactions, including those crucial for muscle contractions and maintaining a healthy heart and immune system (2). (And you thought you were busy!)

Let’s take a closer look at some of the things mighty magnesium does.

Mineral Balancing

Magnesium is vital for balancing other minerals in the body, like calcium, potassium, and sodium.

Think of the body’s essential minerals as a sports team, and magnesium as the head coach.

Magnesium keeps all the players in the right positions, ensuring they function smoothly and don’t compete for attention.

For instance, it prevents calcium from overworking, avoiding muscle cramps and keeping bones healthy.

Energy Production

Every cell in your body needs something called ATP to run – it’s the cellular form of energy, and it’s made in the mitochondria of cells (1, 2).

But ATP is like an uncharged battery without magnesium.

Magnesium helps activate ATP, making it the “charger” that powers every process in your body.

Hormonal Balance

Magnesium has a significant impact on hormone regulation (1, 2).

It supports thyroid health and helps you manage stress, affecting your mood and energy levels (3).

Hormonal imbalances can cause a range of issues, from stress to fatigue.

You know those days where you want to curl up and cry or explode in a fit of anger with almost no provocation? Or when the littlest thing happens and you Just. Can’t. Deal?

Magnesium might help even out your hormones and stress response.

Digestion and Gut Health

Magnesium is important for digestion and gut health.

It helps regulate digestive processes, such as peristalsis, which are wave-like muscle contractions that move food through the digestive tract like a conveyor belt.

This mineral also supports the migrating motor complex, a series of contractions that clear out remaining food in the intestines between meals.

Inadequate magnesium levels can lead to constipation, as it affects water balance in the intestines, softening stools, and promoting smooth passage.

This mineral also maintains gut flora balance, encouraging beneficial bacteria growth.

A 2024 study found a statistically significant inverse relationship between magnesium intake and the development of gallstones (7). (High intake is associated with low prevalence of gallstones.)

Sleep and Relaxation

You may already know that magnesium plays a key role in sleep and relaxation, but do you know how it works?

It helps regulate neurotransmitters like GABA, which promotes relaxation and restful sleep.

Further, adequate magnesium levels can help reduce the stress hormone cortisol.

All of this can lower anxiety levels and soothe the nervous system, paving the way for your sweet dreams (4).

Brain Health and Cognitive Function

Magnesium is essential for brain health, cognitive function, and protection.

It enhances memory and reduces neuroinflammation, which can make you feel unfocused and like you’re wandering around in a fog.

Magnesium supports the formation of synaptic connections, crucial for efficient communication between neurons (5, 6).

Magnesium may help protect against age-related cognitive decline and enhance overall brain performance (5, 6).

Why So Many People Don’t Get Enough Magnesium

Many factors contribute to magnesium deficiency, including poor soil quality, unhealthy eating habits, and stress.

Depleted Soils

Soil health is crucial for producing nutrient-rich foods.

Modern farming practices have changed the way food is grown, which affects the nutrient content of the soil (1).

When industrial chemicals are used, they can drain essential minerals from the earth. This results in crops that contain less magnesium, impacting your diet (1).

Without magnesium-rich soil, even fresh produce can lack this important mineral.

Signs of Magnesium Deficiency

Low energy is a common symptom of magnesium deficiency. It’s like your body’s battery is running low. Other signs of low serum magnesium levels include (1):

• Muscle cramps, spasms, or weakness
• Digestive issues, like poor digestion and constipation
• Nausea
• Headaches and even migraines could be signs as well.
• Mood changes, such as anxiety, depression, or feeling restless
• Irregular heartbeat or heart palpitations
• Numbness or tingling
• Trouble sleeping
• Unexpected chocolate cravings
• Hormonal imbalances, like PMS or thyroid dysfunction
• Chronic diarrhea and heartburn

Different Types of Magnesium Supplementation and Their Unique Benefits

Magnesium comes in various forms, each with its own benefits and uses. Whether it’s relieving muscle cramps or supporting brain health, different types of magnesium supplements may help in different ways.

(Spoiler alert: I’ll share my favorite magnesium products at the end!)

Dietary Choices and Reduced Magnesium Intake

Processed foods are a staple in the Standard American Diet (SAD) even though they often lack magnesium.

One study found that processed white flour loses 82% of its magnesium, polished rice loses 83%, and processed white sugar loses 99% of its magnesium (1).

A reduced intake of magnesium in the diet can lead to low blood levels of magnesium.

Stress

Chronic stress is known to harm your body in many ways, including depleting magnesium levels.

Stress can increase your body’s demand for magnesium, affecting not only your mood but also your overall health (3).

Adverse Effects of Medications

Some medications can cause low levels of magnesium in your body.

Diuretics, proton pump inhibitors, and even some antibiotics can lower magnesium absorption or increase its excretion.

Conditions like type 2 diabetes, and treated with medications such as hydrochlorothiazide (HCT), can also contribute.

Age

As you age, your body’s capacity to absorb magnesium naturally decreases.

Chronic conditions like hypertension and kidney disease become more common and can further affect magnesium levels.

Magnesium Glycinate

Magnesium glycinate is known for its high bioavailability, which means your body absorbs it well (12).

This makes it great for improving sleep quality and reducing stress.

Magnesium Citrate

Magnesium citrate is often used as a natural remedy for digestion issues.

It’s effective for relieving constipation and is sometimes used to prevent or alleviate muscle cramps (11).

Magnesium Malate

Magnesium malate is a type of magnesium that can help boost your energy levels.

It’s also been noted for its potential benefits in easing muscle pain from your latest workout (12).

Magnesium L-Threonate

Magnesium L-threonate is unique for its ability to support cognitive function (12).

It can cross the blood-brain barrier, which enhances its impact on brain health.

Magnesium Oxide

Magnesium oxide is often used as a laxative (9).

It’s less absorbed by the body compared to other forms, but is effective for its intended purpose.

Magnesium Chloride

Magnesium chloride is well-suited for topical applications.

It’s commonly used to relieve muscle tension and promote relaxation (10).

Magnesium Taurate

Magnesium taurate is beneficial for cardiovascular health (8).

It’s specifically known for helping regulate blood pressure.

This type of magnesium combines magnesium with the amino acid taurine, which is good for heart health.

Now that we’ve looked at some of the common types of magnesium, we need to talk about what to avoid in your supplementation.

What To Avoid in a Dietary Supplement

Choosing magnesium supplements can be tricky because of poor absorption and unwanted additives. It’s important to be aware of low-quality forms, fillers, and misleading labels.

Low Quality Forms

Not all magnesium supplements are the same.

Some forms, like magnesium oxide, are poorly absorbed by your body.

This means you might not get all the benefits you’re hoping for.

Look for forms like magnesium glycinate or citrate, which are more easily absorbed.

By choosing the right form, you’ll maximize the health benefits you’re looking for.

Fillers And Flow Agents

Many supplements include unnecessary additives.

Fillers and flow agents are often used in pills to make them easier to produce but don’t add any health value.

Worse, they may even harm your health.

These flow agents can sometimes interfere with absorption, reducing the effectiveness of the magnesium.

When selecting a supplement, check the label for these ingredients:

• Magnesium stearate
• Silicon dioxide (silica)
• Magnesium silicate (talc)
• Calcium silicate
• Titanium dioxide
• Microcrystalline cellulose (MCC)
• Dicalcium phosphate
• Starch
• Maltodextrin

Aim for products that contain pure magnesium without extra fillers or additives, ensuring you get the highest quality available.

Misleading Labeling

Supplement labels can be confusing.

Some products use terms like “proprietary blend,” which can hide the exact amounts of ingredients, making it hard to know if you’re getting enough magnesium.

Misleading labeling may also exaggerate benefits or use small print to hide potential side effects.

Always read the labels carefully and choose reputable brands that clearly list their ingredients and amounts. (How do you know if a brand is reputable? I can help!)

Flavored Magnesium Powders

Flavored magnesium powders might seem appealing, but they often contain artificial sweeteners, coloring, or sugar.

These additives can trigger inflammation and other issues.

Choosing The Right Magnesium For You

Understanding different forms of magnesium can help you make a tailored choice. Consider why you need magnesium, ensure it’s from a reliable source, and explore different methods of use.

Take a Magnesium Supplement Tailored To Your Needs

Different forms of magnesium target specific health areas. Make sure you’re taking the right kind of magnesium for your health concern. For example:

• Magnesium glycinate: Sleep support and stress reduction
• Magnesium citrate: Constipation relief
• Magnesium L-threonate: Brain health and cognitive function
• Magnesium taurate: Cardiovascular benefits

Look For Third-Party Testing

When choosing magnesium supplements, it’s essential to select products that have been independently tested by third-party organizations.

Third-party testing verifies the product’s potency and purity.

Look for certifications on product labels, which indicate that an independent lab has tested it.

Magnesium Oils And Bath Salts are High in Magnesium

If oral supplements are not your thing, consider transdermal options like magnesium oils and bath salts.

Magnesium chloride is often used in sprays for easy skin absorption, providing a convenient way to increase magnesium intake.

Bath salts (like Epson salt) can offer a relaxing experience while allowing magnesium to absorb through the skin.

This method not only helps with muscle relaxation but is one of my favorite ways to unwind after a stressful day.
