Magnesium is an essential mineral with a wide range of biological functions, yet the majority of the population does not get enough dietary magnesium to meet daily requirements. Magnesium makes up the center of every ATP (energy) molecule in the body, but also helps in muscular relaxation. When supplemented in the citrate form, magnesium can also improve gastrointestinal motility. 


What is Magnesium Citrate?

Magnesium is an essential mineral, meaning it is needed by, yet not made within the body. Unfortunately, three-quarters of Americans are also estimated to be deficient in magnesium [1]. 

Magnesium makes up the center of every ATP (energy) molecule in the body and works as a cofactor in over 300 enzymatic reactions in the body [2]. Taking magnesium before bed can help stave off restless leg syndrome [3] and aid in the regularity of bowel movements without causing diarrhea [4]. 

Magnesium citrate is one of the most popular and easily absorbed magnesium supplements. In this form, magnesium is bound to citric acid. Because citric acid is a mild laxative, magnesium citrate is a great choice for individuals with occasional constipation.


How does Magnesium Citrate Work?

Magnesium citrate dissolves in water and is highly absorbable by the gut [4]. Magnesium is a cofactor in more than 300 enzymatic reactions within the body; and thus, it is essential for many crucial physiological functions, such as heart rhythm, vascular tone, nerve function, and muscle contraction and relaxation [2]. Magnesium influences vascular tone and reactivity through regulation of cell membrane sodium pump activity, which in turn affects sodium-potassium transport across cell membranes [5]. Magnesium dependent membrane transport affects nerve signaling, muscle contraction, and normal heart rhythm, as well as healthy glucose metabolism.

As a cofactor in reactions needed for energy production, magnesium aids in several processes leading to the metabolism of carbohydrates and fats. On top of this, ATP, the molecule that provides energy for nearly all metabolic functions, exists primarily as a complex involving magnesium [6]. 

Magnesium is also involved in the utilization of calcium, phosphorus, sodium, and potassium, the synthesis of DNA, RNA, proteins, and glutathione, the body’s “master antioxidant” [6]. The growth and maintenance of your bone structure and mineralization are also magnesium-dependent [6]. 


What are the Suggested Uses for Magnesium Citrate?

  • Regulate bowel movements - Magnesium citrate, specifically, acts as a mild laxative for motility of the gastrointestinal system.
  • Promote a calm mood and healthy sleep - regulation of pain receptors and the relaxation of muscles can aid in a quicker onset of sleep and a more relaxed state of mind and body.
  • Muscle comfort
