We’ll explain the different types of magnesium you can take during pregnancy. But first, a quick refresher on why you may need to take magnesium while pregnant.

Why do pregnant women need to take magnesium?

In general, magnesium is an essential mineral. It’s responsible for a myriad of bodily functions, and helps relax our bodies.

It is pretty common for people to experience magnesium deficiency, especially as food quality continues to drop and nutrition becomes poorer.

But, pregnant women are especially susceptible to a magnesium deficiency. While you are pregnant, you are feeding not just yourself, but your growing baby as well.

So, many essential nutrients are siphoned by the fetus. Plus, your changing hormones can contribute to a magnesium deficiency. Some common signs of this include:

  • Loss of appetite
  • Fatigue
  • Insomnia
  • Muscle twitching
  • Poor memory
  • Irregular heartbeat
  • Weakness
  • Nausea and vomiting

Benefits of magnesium supplementation

Even if you aren’t yet deficient, you may want to supplement with magnesium anyways. There are tons of benefits for expecting women, including:

  • Reduced leg cramps or restless leg syndrome (RLS)
  • Preventing osteoporosis
  • Helping with nausea and morning sickness
  • Improves your delivery process
  • Helping manage headaches
  • Positively impacts your child

These are just some of the most prominent benefits of magnesium supplementation. If you want to learn more, check out our complete guide on the benefits of magnesium during pregnancy.

If you want to learn more about this, you can check out our post on the safety of magnesium during pregnancy. But, you came here to learn what the best kind of magnesium to take while pregnant is. So, without further ado, let’s discuss the different types!

Taking magnesium transdermally vs orally

There are two ways you can supplement with magnesium: transdermal or oral. Transdermal supplementation means you are applying a magnesium lotion or gel directly on your skin, typically where you are trying to receive the benefits.

So, if you are experiencing restless legs, you would massage a magnesium lotion into your leg muscles. Or, if you have sore hips, you can massage a lotion into your hips.

Supplementing magnesium orally is what comes to mind for most people. This is where you take a capsule or pill, and ingest it into your system that way.

This is easier for a lot of people, which is why they prefer it. But, which method is really better for pregnant women?

We Recommend Pregnant Women Take Magnesium Transdermally

There are a few reasons taking magnesium topically while pregnant is superior to taking it orally.

For one, it's a great way to massage sore muscles and the benefits can be achieved in a more specific area. By rubbing magnesium directly into sore muscles in your legs, back, hips, feet, etc, you can target the inflammation directly.

But the main reason we don’t recommend taking magnesium orally is because your body cannot absorb it as well. A lot of the magnesium supplements can cause stomach aches and diarrhea, as the body cannot break them down and use them effectively. This means you are wasting your money with magnesium supplements, while adding discomfort to an already stressful and uncomfortable pregnancy.

Topical supplementation, on the other hand, has way higher absorption rates and won’t produce the displeasures of taking it topically. Plus, using a magnesium lotion provides the added benefits of moisturizing your skin! So, in summary:

  • Taking magnesium orally can lead to stomach aches and diarrhea
  • Your body cannot process oral magnesium as effectively or efficiently as transdermally
  • When you apply magnesium lotions, you can target the problem areas on your body more effectively and get better relief

What are the different types of magnesium women take during pregnancy?

There are so many different kinds of magnesium that it can get overwhelming as you do your shopping or research. The big differences between them are the absorption rate and the therapeutic benefits each offers. They also differ in terms of side effects.

there are many different types of magnesium you can take while pregnant

We will just focus on the eight most prominent varieties of magnesium commonly used by pregnant women today. Then, we will offer our selection as the best kind of magnesium to take while pregnant.

Magnesium Sulfate

Magnesium sulfate is most known for its presence in Epsom salts. Using magnesium sulfate topically is one of the best ways to combat sore muscles or aches, and can even be used to help with digestive issues.

This type of magnesium is often prescribed to prevent premature birth and decrease uterine tone in those with heightened risk for these two pregnancy complications. In this instance, you should consult your doctor, as they will help come up with a treatment plan.

However, according to certain studies, magnesium sulfate should not be taken during the first trimester at all. Some even suggest it might not be safe throughout pregnancy at all, unless to treat one of the aforementioned conditions. This form of magnesium should only be taken upon a doctors prescription.

Magnesium Phosphate

This is a very mild form of magnesium, that does wonders for people with cramps or tightness. It calms the body and mind, while simultaneously contributing to healthier bones and teeth, while keeping the body’s processes in balance with one another.

Magnesium Citrate

As the name suggests, magnesium citrate is derived from citric acid. One of the main advantages magnesium citrate has over other types its bioavailability - meaning its easily absorbed and utilized by the body. Mothers experiencing indigestion and acid reflux/morning sickness will be pleased to learn that magnesium citrate can combat these issues.

But, magnesium citrate also has been shown to act as a strong laxative - good for those with constipation issues, not so good for those just looking for relief from leg cramps during pregnancy! Nonetheless, it is considered safe for both you and your child during pregnancy.

Magnesium Oxide

Magnesium oxide has much lower levels of bioavailability compared to magnesium citrate, but is still commonly used to treat digestion related issues. Magnesium oxide is one of the main compounds found in Milk of Magnesia.

According to the National Institutes of Health, it is not advisable to take this form during pregnancy, or any long period of time for that matter.

Magnesium Glycinate

For those that are dealing with stress on top of their magnesium deficiency, magnesium glycinate may be the answer. 

This unique type of magnesium mends a stressed mind and body. It has a bioavailability that rivals that of magnesium citrate, and unlike many types of magnesium, is not a known laxative! Magnesium Glycinate is by far the easiest type of mg on the stomach. But, this form is one that some doctors are hesitant to recommend, and will only prescribe in an instance where the benefits outweigh the risks.

Magnesium Orotate

Magnesium orotate is unique from other types of magnesium, because it also organically encourages heart health. On top of this, it can help repair muscle tissues, leading to an increase in stamina and energy. Because magnesium orotate is such a versatile supplement, it tends to be more expensive than other types of magnesium.

Magnesium L-threonate

This variation of magnesium has been considered a “breakthrough” supplement by some. It features high bioavailability, and has the power to improve cognitive functions (huge for those who suffer from mom brain). 

Magnesium chloride

When you use magnesium supplements, magnesium chloride is usually what you’ll see on the ingredient label. This is the most common kind of magnesium, which is typically extracted from brine or ocean water.

Studies have shown that this variation is the most effective form of oral supplementation, but it works even better topically.

Magnesium chloride promotes deep sleep, healthy digestion, bone health, and a calming presence - both mentally and physically. It also does wonders for nausea and morning sickness. The one main side effect with magnesium chloride is diarrhea, which is typical across all types of magnesium. But, this is pretty uncommon unless you go overboard on your dosage.
