Understanding Magnesium Citrate

Magnesium citrate is a common over-the-counter treatment for constipation. This compound is a combination of magnesium and citric acid. It works as an osmotic laxative, which means it draws water into the intestines. This additional water softens the stool and helps with bowel movements.[1]

Many individuals use magnesium citrate to alleviate occasional constipation. Some also take it as a supplement to increase their magnesium intake. Magnesium is an essential mineral that the body needs for many functions, including muscle and nerve activity, energy creation, and maintaining healthy bones.[2]

Magnesium citrate tends to work quickly and effectively for most people. It is versatile because it can act both as a laxative and a magnesium supplement. However, it’s important to understand how it works and what the potential risks are to use it correctly.[3]

What is Magnesium Citrate?

Chemical Composition

Magnesium citrate is made up of magnesium ions bound to citrate. Citrate is a salt form of citric acid. This combination creates a stable compound that the body can absorb easily.[4]

The chemical formula for magnesium citrate is Mg3(C6H5O7)2. Each molecule contains three magnesium atoms and two citrate ions. This specific structure helps the body receive magnesium effectively.[5]

Compared to other magnesium supplements, citrate has high bioavailability. This means the body can absorb and use it readily. Some other forms, like magnesium oxide, are not as easily absorbed.[6]

Component Role in Magnesium Citrate
Magnesium Active mineral, supports various bodily functions
Citrate Improves absorption, adds laxative effect
Water Dissolves the compound, aids in intestinal fluid increase

Forms and Preparations

Magnesium citrate is available in different forms to suit different needs:

  1. Liquid: This is the most common form for laxative use. It’s typically flavored to make it more palatable. Liquid magnesium citrate works quickly and is easy to take.

  2. Powder: This form can be mixed with water or other liquids. It allows for flexible dosing and is good for those who prefer not to swallow pills.

  3. Capsules or tablets: These are convenient for daily magnesium supplementation. They offer precise dosing but may work more slowly for laxative effects.

Each form has unique benefits. Liquid forms tend to work the fastest for relieving constipation. Powder allows for more flexibility in adjusting the dosage. Pills are often better for long-term supplementation.[7]

Some well-known brands that offer magnesium citrate products include:

  • Phillips’ Milk of Magnesia

  • Nature Made Magnesium Citrate

When choosing a magnesium citrate product, think about what you need and prefer. Factors like taste, how easy it is to use, and what you intend to use it for should influence your decision.[8]

How Magnesium Citrate Works

Mechanism of Action

Magnesium citrate affects the digestive system in several ways. Its main function is to act as an osmotic laxative. It does this by drawing water into the intestines through a process called osmosis.[9]

When you take magnesium citrate, it passes through the stomach without being changed. It begins to break down in the small intestine. The magnesium ions then attract water molecules, which softens the stool and increases its volume.[10]

The increased water content makes the stool easier to pass. It also encourages intestinal contractions, known as peristalsis. These contractions help to move the stool through the colon.[11]

In addition to its laxative effects, magnesium citrate also influences muscle and nerve function. Magnesium is involved in over 300 enzyme systems. These systems control many chemical reactions, such as protein creation, muscle and nerve function, and energy production.[12]

In muscles, magnesium helps to control contractions. It plays a role in how calcium is taken up and released in muscle cells. This action can help to relieve muscle cramps and tension.[13]

For nerves, magnesium works as a natural calcium blocker. It helps to regulate the release of neurotransmitters. This can have a calming effect on the nervous system. Some people find magnesium helpful for sleep and reducing stress.[14]

Absorption and Bioavailability

The body absorbs magnesium citrate effectively. Most absorption happens in the small intestine. The citrate in the compound helps to improve magnesium absorption by forming soluble magnesium citrate complexes.[15]

Compared to other magnesium forms, citrate has high bioavailability. Bioavailability refers to how much of a substance the body can actually use. Research has shown that magnesium citrate is more bioavailable than magnesium oxide.[16]

Several things can affect how well magnesium is absorbed:

  1. Dosage: Large doses are less efficiently absorbed.
  2. Gastrointestinal health: Certain conditions can impair absorption.
  3. Diet: Some foods can enhance or inhibit magnesium absorption.
  4. Age: Absorption tends to decrease with age.
Magnesium Form Approximate Bioavailability
Magnesium Citrate 25-30%
Magnesium Oxide 5-10%
Magnesium Glycinate 20-25%
Magnesium Chloride 20%

This information helps explain why many people choose magnesium citrate. Because it is highly bioavailable, more magnesium reaches your cells. This can lead to better results, especially when used for magnesium supplementation.[17]

Benefits of Magnesium Citrate

Digestive Health

Magnesium citrate is good at promoting regular bowel movements. Its osmotic effect draws water into the intestines, which softens the stool and increases its bulk. This softer, bulkier stool is easier to pass.[18]

For occasional constipation, magnesium citrate can provide fast relief. Most people will have a bowel movement within 30 minutes to 6 hours after taking it. This makes it useful for short-term constipation issues.[19]

Beyond just relieving constipation, magnesium citrate supports overall digestive health. Regular bowel movements help the body remove waste and toxins. This can improve gut health and help with nutrient absorption.[20]

Some people use magnesium citrate for colon cleansing. It’s often used before medical procedures like colonoscopies. The thorough cleansing helps doctors see the colon clearly.[21]

However, it’s not recommended for long-term use without a doctor’s advice. Overuse can cause electrolyte imbalances and dependence. For ongoing constipation, it’s best to talk to a doctor to find out the cause.[22]

Magnesium Supplementation

Magnesium citrate is also an excellent magnesium supplement. Magnesium is needed for many important bodily functions. It helps with energy production, protein creation, and maintaining healthy genes.[23]
