Magnesium Citrate


Magnesium citrate is a chemical compound that combines the mineral magnesium with citric acid. It is commonly used as a dietary supplement due to its high bioavailability, meaning it is easily absorbed by the body. The compound is usually available in the form of a white powder or a tablet. Magnesium, an essential mineral, plays a crucial role in various bodily functions. It is involved in over 300 enzymatic reactions, contributing to processes such as energy production, muscle and nerve function, and protein synthesis. However, the body cannot produce magnesium on its own, so it must be obtained through diet or supplementation. Citric acid, a naturally occurring organic acid found in citrus fruits, enhances the absorption of magnesium in the body. This combination creates magnesium citrate, a highly soluble form of magnesium that can be readily absorbed in the gastrointestinal tract. Due to its solubility, magnesium citrate is often used as a laxative to relieve occasional constipation. It works by drawing water into the intestines, softening the stool and promoting bowel movements. Therefore, it is commonly found in over-the-counter laxative products. Moreover, magnesium citrate is sometimes used to prepare the bowel before certain medical procedures or surgeries. Its ability to induce bowel movements helps to empty the colon effectively. In addition to its laxative properties, magnesium citrate is also taken as a dietary supplement to support overall health and well-being. It is believed to help maintain normal muscle and nerve function, support a healthy cardiovascular system, and contribute to bone health. Overall, magnesium citrate is a compound that combines magnesium and citric acid, offering high bioavailability and various potential health benefits.
