Magnesium Citrate Nonahydrate Description
Magnesium Citrate Nonahydrate is a high-purity, organic mineral compound consisting of magnesium combined with citric acid, containing nine molecules of water of hydration (nonahydrate). It appears as a white, crystalline powder that is freely soluble in dilute acids but only slightly soluble in water.
Magnesium is an essential mineral that plays a critical role in over 300 enzymatic reactions in the human body, including energy production, muscle and nerve function, blood glucose control, and protein synthesis. The citrate form offers excellent bioavailability, meaning magnesium citrate nonahydrate is easily absorbed and utilized by the body.
Our Magnesium Citrate Nonahydrate is manufactured under strict quality control standards to ensure high purity and consistent particle size. It is widely used in the nutraceutical, food, and pharmaceutical industries as a premium source of magnesium for dietary supplementation and food fortification.
