Magnesium is a mineral that is important for many bodily functions, including nerve and muscle function, protein synthesis, and blood pressure regulation. There are different types of magnesium supplements available, including magnesium citrate and magnesium oxide. While both of these supplements provide dietary magnesium, they have different benefits and drawbacks. In this article, we will discuss the difference between magnesium citrate and magnesium oxide. We will also explore when it might be best to take each supplement.
What is Magnesium Citrate?
Magnesium Citrate is a chemical compound that is commonly used as a laxative and digestive aid. It is available in both oral and injectable forms. Magnesium Citrate works by drawing water into the intestinal tract, which softens the stool and makes it easier to pass. It is typically taken once or twice a day, depending on the severity of constipation. Magnesium Citrate is generally well tolerated, but side effects may include abdominal cramping, bloating, and diarrhea. Magnesium Citrate is available over-the-counter and does not require a prescription.
What is Magnesium Oxide?
Magnesium oxide is a white solid with the formula MgO. It is a basic magnesium compound. Magnesium oxide is used in a variety of applications, including as an antacid, a refractory material, and an electrical insulator.
- Magnesium oxide can be found in nature as the mineral periclase. It is produced commercially by the calcination of magnesium carbonate or magnesium hydroxide.
- Magnesium oxide is a food additive approved by the US FDA for use as an antacid and a dietary supplement. Magnesium oxide has many industrial uses, including in the production of Portland cement, fireproofing agents, and ceramics.
- It is also used as an insulator in electrical cables and as a filler in plastics. Magnesium oxide is generally safe when used as directed. However, side effects may include diarrhea, stomach upset, and vomiting. Magnesium oxide should not be used by people with kidney disease or heart failure. Magnesium oxide is available without a prescription.
Difference between Magnesium Citrate and Magnesium Oxide
Magnesium oxide and magnesium citrate are two forms of magnesium that are commonly used for supplementation. Magnesium oxide is the most common form of magnesium supplement, and it is also the cheapest. Magnesium citrate is less commonly used but is more expensive. Magnesium oxide is less bioavailable than magnesium citrate, meaning that less of it is absorbed by the body. Magnesium citrate is also more effective at relieving constipation than magnesium oxide. For these reasons, magnesium citrate is generally the better choice for supplementation, although it is more expensive.
Conclusion
Magnesium oxide is the most common form of magnesium supplement, but it’s not as easily absorbed by the body as other forms. Magnesium citrate is a better choice for people with digestive issues because it’s more soluble. If you’re looking for a magnesium supplement, be sure to check the ingredients to see which form of magnesium is used.
