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

  • Reduced leg cramps or RLS
  • Preventing osteoporosis
  • Helping with nausea and morning sickness
  • Improves your delivery process

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.

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 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 very well topically too. 

Magnesium chloride promotes deep sleep, healthy digestion, bone health, and a calming presence - both mentally and physically. The one main side effect with magnesium chloride is diarrhea. But, this is pretty uncommon unless you go overboard on your dosage.

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.

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.

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.

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). 

What Is The Best Type Of Magnesium To Take While Pregnant?

The best type of magnesium to take while pregnant is sort of up for debate. There are a few that we know work very well. Most doctors will recommend you take magnesium with a high bioavailability, which narrows it down to a few. These include magnesium chloride, oxide, citrate, and glycinate.
