Hebei Messi Biology Co., Ltd. states that as people increasingly focus on health and quality of life, the market for nutritional supplements is also expanding rapidly. As an important source of magnesium, magnesium oxide (MgO) plays an indispensable role in the preparation of magnesium citrate due to its high purity, good stability, and bioavailability.

Magnesium oxide (MgO) is a common chemical substance often used as an antacid, a nutritional supplement for supplementing magnesium, and has wide applications in the industrial and pharmaceutical fields. Magnesium citrate, on the other hand, is a salt compound formed by the combination of magnesium ions and citrate ions. Magnesium citrate is widely used as a food additive and nutritional supplement because it has good water solubility, is easily absorbed by the human body, and has a relatively good taste, without causing stomach discomfort like some other forms of magnesium supplements. Magnesium citrate can be used to supplement the magnesium needed by the human body, helping to maintain normal neuromuscular function, heart rhythm, and bone health.
Neutralizing Acidity and Alkalinity
Magnesium oxide may play a role in providing a magnesium source during the preparation of magnesium citrate. Specifically, in the production process, magnesium oxide can react with citric acid to produce magnesium citrate. This process is generally carried out under controlled conditions to ensure product purity and quality. In addition, since magnesium oxide is alkaline, it can neutralize the acidity of citric acid, thereby forming a stable magnesium citrate salt.
Improving Magnesium Absorption Efficiency
The application of magnesium oxide in magnesium citrate not only lies in providing the necessary magnesium ions, but more importantly, it can significantly improve the absorption rate of magnesium. Studies have shown that magnesium citrate, formed by combining magnesium oxide with citric acid, can have a magnesium content of up to 11%, and this form of magnesium is more easily absorbed by the human intestinal tract, thereby effectively improving magnesium levels in the body and helping to maintain normal neuromuscular function, heart rhythm, and bone health.
Improving Product Physical Properties
It is worth noting that after adding magnesium oxide, the particle size of magnesium citrate becomes finer, which makes the product easier to dissolve in water or other liquids, greatly improving the convenience of taking it. For those who need to supplement magnesium regularly, this means they can receive more convenient and effective nutritional support.
