Magnesium Citrate Vs. Oxide: Which Laxative Is Superior?

Magnesium is an essential mineral that plays a critical role in several bodily functions, including energy production, DNA synthesis, and bone structure. While it is naturally present in many food sources, such as green leafy vegetables and legumes, magnesium supplements are often necessary to meet the recommended daily intake. Two common forms of magnesium supplements are magnesium oxide and magnesium citrate, which differ in their effectiveness and are used to address different health concerns.

Magnesium citrate is more soluble and has a higher bioavailability than magnesium oxide

Magnesium citrate is a form of magnesium bound with citric acid, which is found naturally in citrus fruits. It is one of the most common magnesium supplement formulations and is easily absorbed by the body.

Magnesium oxide, on the other hand, is a salt that combines magnesium and oxygen. It occurs naturally as a white, powdery substance and may be sold in powder or capsule form.

Magnesium citrate has higher solubility and bioavailability than magnesium oxide. A 2003 study of 46 adults found that magnesium citrate was absorbed better than magnesium oxide. Another study compared the solubility of 25 mmol of magnesium citrate and magnesium oxide in solutions containing varying amounts of hydrochloric acid. Magnesium oxide was virtually insoluble in water, while magnesium citrate had high solubility even in water.

The higher solubility of magnesium citrate means that it is more easily absorbed in the digestive tract. This makes it a more effective supplement for raising magnesium levels in the body. It is also used to treat constipation due to its natural laxative effect.

In summary, magnesium citrate is more soluble and bioavailable than magnesium oxide, making it a more effective supplement for raising magnesium levels and treating constipation.

Magnesium oxide has more elemental magnesium per gram

Magnesium oxide is an inorganic salt of magnesium formed with ions of magnesium and oxygen. It is one of the most common forms of magnesium sold in supplement form.

Magnesium oxide contains more elemental magnesium per gram than other magnesium supplements. It is made by burning magnesium with pure oxygen. It contains around 60% elemental magnesium, which is the highest percentage amount of all types of magnesium supplements.

However, magnesium oxide has a low solubility rate, making it less bioavailable than other forms of the mineral. It has a lower absorption rate in the intestines compared to other forms of magnesium.

Despite this, magnesium oxide is still an effective remedy for magnesium deficiency symptoms. It is commonly used to treat medical conditions like chronic constipation.

Magnesium citrate is a popular form of magnesium used to treat anxiety and osteoporosis

Magnesium citrate is a popular form of magnesium that is often used as a laxative and can be purchased over the counter. It is bound with citric acid, which occurs naturally in citrus fruits. It is also one of the most easily absorbed forms of magnesium by the body.

Magnesium citrate has been shown to have a beneficial effect on mental health. It can help regulate cortisol, a stress hormone, and balance neurotransmitters, which act as the brain's on and off switches. It has been nicknamed "nature's valium" due to its calming effects. However, more research is needed to confirm these effects.

Magnesium also plays a role in bone health. Studies have shown that lower serum magnesium levels are related to the presence of osteoporosis, and that magnesium supplementation can increase bone mineral density and reduce fracture risk.

In summary, magnesium citrate is a popular and easily absorbed form of magnesium that may be beneficial for treating anxiety and osteoporosis, although further research is warranted to confirm these effects.

Magnesium oxide is used to treat constipation and indigestion

Magnesium oxide is a supplement used to treat constipation and indigestion. It is one of the most common forms of magnesium sold as a supplement, either on its own or in multi-nutrient products. It is also added to over-the-counter medications to treat constipation, indigestion, and headaches.

Magnesium oxide is an inorganic salt of magnesium formed with ions of magnesium and oxygen. It is a magnesium mineral supplement that contains magnesium and oxygen ions. It is available over the counter in supplements and some laxatives.

Magnesium oxide is used to treat constipation in both children and adults. It has an osmotic effect, drawing water into the intestines to act as a laxative. It also softens stools, making them easier to pass. It is considered a safe treatment for constipation, but it may lead to dangerously high magnesium levels in certain populations, such as those with kidney problems or older adults.

Magnesium oxide is also used to treat indigestion and heartburn. It has an antacid action, which can help relieve uncomfortable digestive symptoms. However, it is not typically used to treat or prevent magnesium deficiencies, as studies report that it is poorly absorbed by the digestive tract.

The recommended dosage of magnesium oxide varies depending on the purpose of treatment. For preventing migraines, the recommended dose is 500 mg per day. For treating high blood pressure, the dose is 300 mg per day, and for lowering blood sugar levels in women with gestational diabetes, the dose is 250 mg per day. Higher doses of 1 gram or more are typically used to treat constipation.

Magnesium oxide is generally safe when used in appropriate doses. However, taking large amounts over long periods can lead to high blood magnesium levels, or hypermagnesemia, which can be fatal. This is more likely to occur in those with kidney disease or older adults with bowel disorders. Other potential side effects of magnesium oxide include bloating, diarrhoea, and upset stomach.

Both magnesium citrate and magnesium oxide can be used as laxatives

Magnesium citrate is a popular form of magnesium composed of magnesium and citrate ions. It is commonly used in dietary supplements and multivitamins due to its high bioavailability. It is easily absorbed by the body and is more soluble in water compared to magnesium oxide. Magnesium citrate is often used to treat constipation and can be taken orally in tablet or liquid form. It works by drawing water into the bowel to induce bowel movements. It is also used to treat magnesium deficiency and may offer additional health benefits such as improving high blood pressure and blood sugar levels.

On the other hand, magnesium oxide is an inorganic salt of magnesium formed with ions of magnesium and oxygen. It is one of the most common forms of magnesium found in dietary supplements. While it can also be used as a laxative, it has lower bioavailability than magnesium citrate and is poorly absorbed by the body. This means that it may cause gastrointestinal side effects, such as diarrhea, due to its low absorption rate. However, magnesium oxide may be helpful in treating other health conditions such as headaches and constipation.

When choosing between magnesium citrate and magnesium oxide, it is important to consider your specific needs and health goals. Magnesium citrate is generally recommended for most issues and deficiencies due to its high bioavailability and solubility. However, magnesium oxide may be preferred in certain cases, especially if you are looking for a treatment option for headaches or constipation, and are less concerned about potential gastrointestinal side effects. Consulting with a healthcare professional can help determine which form of magnesium is most suitable for your individual needs.
