Section Divider: What Causes Low Magnesium

What Causes Low Magnesium?

Several factors can contribute to low magnesium levels in the body. The most common causes include the following:

  • Inadequate dietary intake: Many people don’t consume enough magnesium-rich foods, which can lead to a deficiency over time. (1,2)

  • Gastrointestinal disorders: Conditions that affect the digestive system, such as celiac disease, Crohn’s disease, and inflammatory bowel disease (IBD), can interfere with the absorption of magnesium and other nutrients. (1,2)

  • Medications: Certain medications, such as diuretics, proton pump inhibitors, and antibiotics, can interfere with magnesium absorption or increase the amount excreted from the body. (1,2)

  • Alcohol consumption: Because alcohol can interfere with the absorption of magnesium in the intestines, it may cause low levels of the mineral. Additionally, heavy drinking can also increase the urinary excretion of the mineral. (1,2)

  • Chronic health conditions: Certain chronic health conditions, such as diabetes and kidney disease, can increase the risk of magnesium deficiency. (1,2)

It’s important to note that some people may be at higher risk of magnesium deficiency than others, such as those with gastrointestinal disorders, older adults, and certain chronic health conditions. If you’re concerned about your magnesium levels, it’s best to consult your healthcare provider to determine the underlying cause and appropriate treatment.

Section Divider: Types Of Magnesium Supplements

Types Of Magnesium Supplements:

Magnesium supplements are a type of dietary supplement that can be taken orally to increase magnesium intake. They come in various forms, including capsules, tablets, powders, and liquids. When choosing a magnesium supplement, it’s important to consider the type of magnesium used, the dosage, and any potential interactions with other medications or supplements.

There are several types of magnesium supplements, including:

  1. Magnesium Citrate
  2. Magnesium Oxide
  3. Magnesium Glycinate
  4. Magnesium Chloride
  5. Magnesium Sulfate
  6. Magnesium Malate
  7. Magnesium Lactate
  8. Magnesium L-Threonate

Magnesium Citrate:

Magnesium citrate is a highly bioavailable form of magnesium created by combining magnesium with citric acid. The body easily absorbs this form of magnesium, making it a popular choice for addressing low magnesium levels. In addition to promoting overall health and wellness, magnesium citrate is frequently used to treat constipation by softening stools and promoting bowel movements. It’s important to note that magnesium citrate has a natural laxative effect, which can lead to gastrointestinal side effects. Taking magnesium citrate with food is often recommended to reduce the risk of these side effects. (6,7)

Magnesium Oxide:

Magnesium oxide is a magnesium supplement that forms when magnesium combines with oxygen. This form of magnesium has a relatively low bioavailability compared to other magnesium supplements. Because the body absorbs it poorly, it’s not common to use it for addressing low magnesium levels. However, it can still be helpful for the short-term relief of digestive symptoms like heartburn, indigestion, and constipation. Magnesium oxide may also be used to treat and prevent migraines. Individuals with severe magnesium deficiencies or those requiring rapid absorption may not find magnesium oxide to be the best choice due to its lower bioavailability. (8,9)

Magnesium Glycinate:

Magnesium Glycinate, or Magnesium Bisglycinate, is a magnesium supplement that forms when magnesium binds to the amino acid glycine. This combination can help to increase the absorption of magnesium in the body and decrease the likelihood of gastrointestinal side effects. Because of its high bioavailability, Magnesium Glycinate is a popular choice for those looking to improve sleep quality, promote relaxation, and address low magnesium levels. This is because magnesium is crucial in regulating neurotransmitters that affect these functions. This form is generally well-tolerated due to its high bioavailability and low risk of causing gastrointestinal side effects, even at higher doses. (10,11)

Magnesium Sulfate:

Magnesium sulfate, or Epsom salt, is a magnesium supplement that offers more therapeutic benefits. Manufacturers produce it by combining magnesium with sulfur and oxygen, and it comes in various forms, including crystals, granules, and powders. People often use magnesium sulfate topically as a soaking solution for its relaxing and soothing effects. These effects include reducing muscle soreness and joint pain and improving skin conditions such as eczema and psoriasis.  However, very little evidence supports these uses. (13)

Magnesium Malate:

Magnesium Malate is a magnesium supplement that combines magnesium with malic acid, a naturally occurring compound in fruits like apples. This form of magnesium is highly bioavailable, making it a common choice to address low magnesium levels, but it also has additional benefits. For example, malic acid is known for its ability to reduce muscle pain and fatigue, making Magnesium Malate a popular choice for athletes and individuals with fibromyalgia. Additionally, Magnesium Malate may support overall energy production and improve mental clarity. (14,15)

Magnesium lactate is created by combining magnesium with lactic acid. Because this form of magnesium is highly bioavailable, it’s a great option to treat low magnesium levels and supports cardiovascular health and energy production. Additionally, this form of magnesium may help improve muscle function and reduce muscle cramps. Magnesium lactate is generally well-tolerated and has a low risk of causing gastrointestinal side effects. (16)

Magnesium L-Threonate:

Magnesium L-Threonate, or Magtein, is a unique form of magnesium specifically designed to enhance magnesium’s ability to cross the blood-brain barrier and penetrate cell membranes in the brain. This form of magnesium is a combination of magnesium and L-threonate, a vitamin C metabolite that may enhance magnesium absorption in the brain. Magnesium L-Threonate is known for its cognitive benefits, particularly its ability to improve memory and learning. Additionally, studies suggest magnesium L-Threonate supplementation can increase brain magnesium levels, improving synaptic plasticity and neuroplasticity. As a result, this can enhance learning, memory, and cognitive function, potentially reducing the risk of cognitive decline and Alzheimer’s disease. (17)

In addition to its cognitive benefits, magnesium L-Threonate may also have the potential to treat conditions such as anxiety, depression, and sleep disorders. While more research is needed to understand its effects fully, some studies suggest that magnesium L-Threonate supplementation may help improve mood and reduce symptoms of anxiety and depression.

Section Divider: FAQ


Here are some frequently asked questions about low magnesium and magnesium supplements:

Are There Side Effects From Magnesium Supplements?

Although magnesium supplements are generally safe, they can cause some side effects. For example, the most common side effects include diarrhea, nausea, and stomach cramps. However, these side effects are usually mild and go away once the body adjusts to the supplement.

Magnesium For Headaches/Migraines?

Several studies suggest that magnesium supplementation can reduce the frequency and severity of headaches and migraines in some people. Because migraines are frequently linked to low magnesium levels, magnesium supplements may help to prevent migraines and alleviate the symptoms of an ongoing migraine attack.

Does It Help Weight Loss?

Although magnesium is involved in various metabolic processes, such as glucose metabolism and insulin signaling, studies have not shown a consistent effect on weight loss.
