What is magnesium citrate

Magnesium citrate is a magnesium supplement that contains magnesium combined with citric acid. Citric acid is a naturally occurring organic acid found in citrus fruits. This combination creates a compound that is more readily absorbed by the body than some other forms of magnesium.

Magnesium citrate is most commonly used as a dietary supplement to correct magnesium deficiency, which may be caused by insufficient dietary intake, certain medical conditions, medications, or other factors. Magnesium is essential for a variety of bodily functions, including muscle and nerve function, energy production, protein synthesis and maintaining healthy bones and teeth.


What is magnesium citrate


Here are some key points about magnesium citrate:


  • Absorption: Magnesium citrate is often chosen as a supplement because of its relatively high bioavailability, meaning it is effectively absorbed and utilized by the body. The citrate component may increase the solubility of magnesium and its absorption in the gastrointestinal tract.

  • Laxative Effects: In addition to its use as a magnesium supplement, magnesium citrate is also known for its laxative properties. When taken in large amounts, it can act as an osmotic laxative, drawing water into the intestines and promoting bowel movements. Because of this effect, magnesium citrate is sometimes used to relieve constipation or to prepare the bowel for medical procedures such as colonoscopy.

  • Dosage: The appropriate dosage of magnesium citrate varies depending on the individual's needs and health condition. It is important to follow the recommended dosage on the product label or as directed by a healthcare professional.

  • Forms: Magnesium citrate is available in a variety of forms, including liquid solution and tablets. The liquid form is often consumed orally and is commonly used as a laxative. Tablets and capsules are more typical for magnesium supplementation.

  • Health considerations: While magnesium is generally safe for most people when taken within recommended doses, excessive intake may cause side effects such as diarrhea, upset stomach, and potentially interfere with the absorption of other minerals. Individuals with certain health problems or those taking specific medications should consult a health care professional before beginning magnesium citrate supplementation.


Like any dietary supplement, it is important to use magnesium citrate responsibly and under the guidance of a healthcare provider, especially if you have existing health conditions or are taking other medications. They can help determine whether magnesium citrate is suitable for your needs and can advise you on the correct dosage.
