Trimagnesium dicitrate丨CAS 3344-18-1 is a magnesium salt of citric acid, composed of three magnesium ions and two citrate anions. It is widely used as a magnesium supplement, buffering agent, and functional ingredient in nutritional, pharmaceutical, and food formulations.
Key Applications of Trimagnesium dicitrate丨CAS 3344-18-1
1. Dietary Supplements and Nutrition
● Magnesium Source: Commonly used in tablets, capsules, powders, and effervescent formulas to address magnesium deficiency.
● High bioavailability: Better absorbed than magnesium oxide; comparable to magnesium citrate.
● Supports:
o Neuromuscular health
o Bone strength
o Heart and cardiovascular function
o Energy production and metabolic processes
● Suitable for:
o General supplementation
o Sports nutrition
o Prenatal and geriatric health products
2. Pharmaceutical Industry
● Excipient in tablets: Used as a buffer, stabilizer, or mineral fortifier in solid dosage forms.
● Acid regulator: Helps maintain desired pH levels in formulations.
● Can be used in modified-release formulations and as part of mineral blends.
3. Food and Beverage Industry
● Food additive: Added to fortified foods and beverages as a magnesium source (especially in health drinks, powdered mixes, or cereals).
● pH buffer: Stabilizes pH in certain processed foods.
● GRAS status: Considered safe for use in foods by regulatory bodies such as the FDA.
4. Cosmetics and Personal Care
● Included in some skin care and bath products for its magnesium content, which may have calming and soothing effects on the skin.
● Occasionally found in deodorants, face masks, or mineral-rich bath salts.
5. Agricultural Use (Specialized)
● In some formulations, used as a magnesium micronutrient for foliar sprays or soil conditioners to correct magnesium deficiencies in plants (though less common than magnesium sulfate in this application).
Benefits of Trimagnesium dicitrate丨CAS 3344-18-1
1. Bioavailable and Effective
● Trimagnesium dicitrate丨CAS 3344-18-1 offers superior absorption compared to magnesium oxide and many inorganic salts.
● Gentle on the stomach and less likely to cause laxative effects than other magnesium forms.
2. Multifunctional Use
● Provides both magnesium and citrate, which supports energy metabolism and acts as a natural chelating agent.
● Dual role as a mineral supplement and functional additive (pH control, stabilizer).
3. Well-Tolerated
● Generally safe and non-irritating, suitable for daily supplementation.
● Useful in long-term health maintenance, especially in populations with higher magnesium needs (e.g., elderly, athletes, pregnant individuals).
4. Stable and Compatible
● Good stability in powdered blends and tablets.
● Compatible with vitamins, trace minerals, and plant extracts in multi-ingredient formulations.
Conclusion
Trimagnesium dicitrate丨CAS 3344-18-1 is a versatile magnesium source ideal for nutritional, pharmaceutical, and functional food applications. With high bioavailability, good tolerability, and a wide range of formulation uses, it is an increasingly popular choice for supporting magnesium intake and overall health.
