1. Pharmaceuticals 

• Antacid and Laxative: Light magnesium oxide neutralizes excess stomach acid by chemically reacting with hydrochloric acid in the stomach, forming magnesium chloride and water. This helps relieve symptoms of heartburn, acid indigestion, and upset stomach. As a laxative, it attracts water into the intestines, softening stools and promoting bowel movements, useful in treating occasional constipation.
• Magnesium Supplement: Magnesium is vital for many physiological processes, including muscle contraction, nerve transmission, and enzyme activity. Light magnesium oxide provides a bioavailable form of magnesium in oral supplements, helping prevent or treat magnesium deficiency, which can cause muscle cramps, fatigue, and cardiac arrhythmias.
• Excipient and Buffering Agent: In tablet and capsule formulations, it stabilizes the pH environment, protecting active ingredients from degradation due to acidity, and improves drug bioavailability and shelf life.

2. Agrochemicals 

• Soil Conditioner and pH Adjuster: Many agricultural soils become acidic over time due to natural processes and fertilization. Applying Light magnesium oxide raises soil pH (makes it less acidic), improving nutrient uptake by plants. This adjustment helps enhance crop growth and yield.
• Magnesium Nutrient Source: Magnesium is a core element of chlorophyll, essential for photosynthesis. Light magnesium oxide supplies magnesium directly to the soil, correcting deficiencies that cause leaf yellowing (chlorosis) and reduced plant vigor.

3. Food & Healthcare Ingredients

• Food Additive: Used as an anti-caking agent, Light magnesium oxide prevents clumping in powdered food products like salt, spices, and baking powders. It helps maintain free-flowing properties, ensuring consistent product quality. Additionally, as an acidity regulator, it helps maintain the desired pH in processed foods, preserving taste and texture.

4. Performance Chemicals 

• Raw Material for Magnesium Compounds: Light magnesium oxide serves as a starting material to produce other magnesium chemicals, such as magnesium hydroxide (used in flame retardants and antacids), magnesium sulfate (fertilizer and medicine), and magnesium carbonate (used in food and pharmaceuticals).
• Catalyst and Reagent: Its alkaline properties enable it to act as a catalyst or reagent in various chemical reactions, such as in the production of rubber, plastics, and environmental catalysts.
