Is There a Magnesium Supplement That Doesn't Cause Diarrhea or Upset Stomach?

While a good number of us rely on magnesium supplements to enhance our overall well-being, it can some with side-effects. Notably, at high doses, these supplements can sometimes cause an unwelcome side effect: diarrhea or upset stomach.

But why does this happen? Can it be stopped?

And is there a magnesium supplement that doesn't cause loose stools?

We'll explain all below, also introducing you  to nano magnesium, an innovative solution that provides the benefits of magnesium without the unpleasant gastrointestinal side effects. If you're plagued by continual diarrhea from trying to optimise your magnesium levels, it coud really change your life.

Why can magnesium give you diarrhea

The Best Magnesium for a Sensitive Stomach

Nano Magnesium is the gentlest magnesium supplement, making it the ideal choice for those with sensitive stomachs or who experience diarrhea with other magnesium forms. Its unique formulation, featuring extremely small particle size, ensures highly efficient absorption, significantly reducing gastrointestinal discomfort. This makes Nano Magnesium particularly suitable for individuals prone to digestive issues.

Other forms of magnesium that are reasonably well-tolerated and less likely to cause gastrointestinal issues include Magnesium Glycinate and Magnesium Taurate. These are chelated forms, meaning the magnesium is bound to amino acids, improving its bioavailability and reducing the likelihood of diarrhea.

On the contrary, forms like Magnesium Oxide and Magnesium Citrate are more commonly associated with gastrointestinal side effects, including diarrhea, due to their lower absorbability.

Why can Magnesium give you Diarrhea or Upset Stomach?

There's a very simply reason most magnesium supplements cause diarrhea; It has a laxative effect on the digestive tract due to its ability to stimulate smooth muscle contractions in the bowel wall. This results in the rapid transit of stool through the colon and increased water content in the bowel, leading to diarrhea.

Of course, the degree of laxative effect of magnesium depends on the dose, the form of magnesium supplement, and you own sensitivity. For example, magnesium oxide and magnesium citrate, (which are even used for constipation relief), are known to have the most potent laxative effects.

There's another reason for the diarrhea, too. Certain forms of magnesium supplements are poorly absorbed by the body, leading to a higher concentration of magnesium in the intestines, which can also trigger loose stools. This can be particularly problematic with inorganic forms of magnesium, such as magnesium oxide, which have low bioavailability.

Which Magnesium Won't cause Diarrhea?

Not all magnesium gives diarrhea. A new form, Nano Magnesium, is something you can absorb at high doses without digestive distress, as we'll explain below.

In this section, we will explore the different types of magnesium supplements and how they can affect the digestive system.

While some of the forms mentioned are noteably kinder on the GI tract, to our knowledge they all cause gastrointestinal issues, especially at higher doses to some degree: with the exception of nano magnesium.

What Type of Magnesium Gives you Diarrhea?

 Magnesium Citrate

As a widely-used magnesium supplement, magnesium citrate offers dual benefits: it is easily absorbed by the body and acts as a mild laxative. While beneficial for relieving constipation, this form does present a higher likelihood of causing diarrhea due to its laxative properties.

Magnesium Taurate

Magnesium taurate is a preferred choice for individuals with cardiovascular issues, given its protective effects on the heart. When it comes to gastrointestinal effects, this form is absorbed efficiently and is less likely to cause laxative effects or diarrhea compared to other magnesium forms.

Magnesium Malate

Geared towards individuals experiencing fatigue, magnesium malate also boasts a lower risk of causing gastrointestinal issues. Its high solubility and easily broken ionic bonds contribute to a reduced propensity for causing diarrhea.

Magnesium Glycinate

Among the most bioavailable forms, magnesium glycinate poses one of the least risks for causing diarrhea. This form, which is magnesium bound with the non-essential amino acid glycine, has a minimal laxative effect, making it an ideal choice for those sensitive to gastrointestinal disturbances.

Magnesium Chloride

While only containing about 12% elemental magnesium, this form exhibits high absorption rates. Despite its benefits, magnesium chloride can induce diarrhea in some individuals when ingested orally.

Magnesium Carbonate

Magnesium carbonate undergoes a transformation into magnesium chloride upon interacting with stomach acid, providing antacid benefits. This form has a moderate likelihood of causing diarrhea, particularly in those who are susceptible to gastrointestinal issues.


Which Magnesium Has the Least Laxative Effect?

Nano Magnesium is a pioneering liquid supplement specifically formulated to avoid digestive side effects commonly associated with other types of magnesium.

 The Worst Magnesium for Diarrhea

Magnesium Oxide: Often found in pharmacies, magnesium oxide is non-chelated and has a low absorption rate compared to the forms mentioned above. It has a higher likelihood of causing diarrhea due to its poor absorption.

Magnesium Sulfate: Also known as Epsom salt, magnesium sulfate is an effective constipation aid but not a safe source of dietary magnesium due to the risk of overdosing. Its use as a constipation aid suggests a higher likelihood of causing diarrhea if taken in excessive amounts.

Magnesium Glutamate and Aspartate: It is best to avoid these forms of magnesium entirely, as glutamic acid and aspartic acid can become neurotoxic when unbound to other amino acids. These components are found in the harmful artificial sweetener aspartame. The likelihood of diarrhea is unclear for these forms, but their potential neurotoxicity should be a cause for concern.

Now, let's discuss the one form not mentioned in this list: nano magnesium.

How Much Magnesium Before Diarrhea?

The Tolerable Upper Intake Level (UL) signifies the maximum daily dosage of magnesium that is unlikely to cause adverse effects. For magnesium derived from supplements and medications, the UL is set at 350 mg per day for adults. Exceeding this limit increases the likelihood of experiencing diarrhea.

It's also important to consider individual health conditions that could affect magnesium tolerance. People with kidney disorders, for example, are more susceptible to the adverse effects of excessive magnesium intake. Some medications can also interact with magnesium, affecting its absorption and excretion.

Looking for a Magnesium Replacement Without Diarrhea: Try Nano Magnesium

Nano magnesium offers a novel approach to magnesium supplementation. It is a clear liquid, with no taste or smell that uses the amazing power of nano technology, and is the least likely of any available magnesium to cause diarrhea or laxative effects.

Made with ultra-fine particles of pure magnesium that are highly absorbable by the body, Nano Minerals magnesium supplement is designed to bypass the digestive system and be absorbed directly into the bloodstream.

Nanoparticles – extremely small particles with sizes typically ranging from 1 to 100 nanometers - have an increased surface area, which significantly enhances the absorption rate of magnesium in the body. This means that more of the magnesium ingested is utilized by the body, reducing the concentration of magnesium in the intestines and consequently minimizing or even eliminating the risk of diarrhea.
