Industrial Uses

1. Pharmaceuticals

  • Magnesium Supplement for Deficiency: Magnesium citrate is one of the most bioavailable forms of magnesium, widely used in dietary supplements and functional tablets to correct magnesium deficiency, which can cause muscle cramps, fatigue, and arrhythmias.
  • Laxative Agent: Acts as an osmotic laxative by attracting water into the intestines, used in oral preparations to relieve constipation and bowel cleansing before colonoscopies.
  • Nerve and Muscle Support Formulations: Integrated into cardiovascular and neuromuscular support products, as magnesium is essential for nerve impulse transmission and muscle relaxation.

2. Food & Healthcare Ingredients

  • Mineral Fortifier in Functional Foods: Added to health drinks, energy bars, and fortified cereals to enhance magnesium intake, particularly for athletes and aging populations.
  • Acidity Regulator: Used to adjust pH in beverages and flavored waters. It helps balance tartness in citrus-based and electrolyte beverages.
  • Dietary Magnesium Source in Beverages: Used in sports drinks and nutritional supplements for replenishment during physical activity or recovery.

3. Personal Care 

  • Skin Soothing Agent: Used in soothing creams, bath salts, and magnesium sprays to help relieve muscle aches and skin irritation, as magnesium helps regulate skin’s enzymatic functions.

  • Relaxing Bath Products: Commonly included in magnesium bath soaks or body sprays, often marketed for stress relief, sleep aid, and post-workout recovery.

4. Animal Healthcare

  • Magnesium Supplement for Livestock: Added to animal feeds or oral solutions to prevent hypomagnesaemia (grass tetany) in cattle and sheep, particularly during high-lactation periods or low-magnesium pastures.
  • Improves Bone Strength in Pets: Used in nutritional pet supplements for bone and muscle development, especially in growing or aging animals.

5. Performance Chemicals

  • Buffering Agent in Lab Formulations: Used in laboratory media and culture preparations as a mild alkaline buffer and magnesium source in biochemical reactions.
  • Intermediate in Pharma Raw Material Synthesis: Used as a source of magnesium ions or as a chelated magnesium compound in certain synthetic pathways or intermediates.
