Organic-Chelated Base Material for Magnesium Fortification
Magnesium Citrate is an organic-chelated magnesium nutritional fortifier produced by complexation of magnesium ions with citric acid. It is a permitted magnesium source complying with GB 14880. Compared with inorganic magnesium salts, it features good gastrointestinal tolerance, low bitter taste, favourable bioavailability and excellent compounding stability. It is widely used in special-diet foods, health foods, solid beverages, dairy products and other sectors. It has four core attributes: good bioavailability, superior sensory performance, low gastrointestinal irritation and strong formula compatibility.
Main Components: Magnesium citrate, molecular formula Mg₃(C₆H₅O₇)₂, CAS No. 3344-18-1
Core Specifications: Magnesium content ≥12.0 %; heavy metals (lead, arsenic, cadmium) comply with limit values specified in GB 1903.19; loss on drying, sulphates, oxalates and other indicators meet regulatory requirements; customisable particle-size available.
Appearance: White to off-white fine powder, nearly odour-free. Loose and uniform powder with good flowability, free of caking and visible impurities.
Stability: Stable physicochemical properties in solid state; prone to precipitate under strongly-alkaline aqueous-solution conditions. Avoid compounding with high-concentration phytic acid and tannins. Shelf-life: 24 months under sealed, cool and dry storage conditions.
Solubility: Slightly soluble in water, insoluble in ethanol. Dissociates and releases magnesium ions under weakly-acid and neutral conditions. Exhibits excellent compatibility with proteins, colloids, sugar alcohols, vitamins and minerals.
➢Regulatory: Complies with GB 1903.19-2016, listed as an approved nutritional-fortifying magnesium source under GB 14880. Permitted for ordinary foods, complementary foods for infants and young children, special-diet foods and health foods with clean and compliant labelling.
➢Absorption: Organic-chelated structure with low gastric-acid dependence. Less affected by dietary inhibitory factors such as phytic acid compared with inorganic magnesium sources including magnesium oxide and magnesium sulphate, delivering outstanding bioavailability.
➢Sensory: Chelation binds free magnesium ions, significantly reduces bitter-astringent taste of magnesium salts and causes little interference to finished-product flavour and colour.
➢Formulation Suitability: Applicable to both solid and weakly-acid liquid systems; generates synergistic effects together with vitamin D and vitamin K2. Keep away from high-concentration phytic acid and polyphenols to prevent decline in magnesium absorption efficiency.
➢Practicality: Stable magnesium content with controllable addition dosage. Good powder-processing performance and high batch-to-batch consistency, with better comprehensive sensory performance than most inorganic magnesium salts.
The citrate-chelated structure reduces reliance on gastric-acid dissociation. Magnesium ions can be effectively released under weakly-acid and neutral gastrointestinal environments, with low interference from dietary phytic acid and dietary fibre to guarantee magnesium absorption efficiency.
The chelated structure suppresses bitter-astringent off-flavours brought by free magnesium ions. It hardly triggers product discoloration or flavour deterioration, maximally preserves original food taste and fits clean-label formulas.
Less irritating to digestive tract than inorganic magnesium salts such as magnesium sulphate and magnesium oxide, lowering risks of abdominal distension and diarrhoea. Suitable for long-term dietary magnesium supplementation for gastrointestinal-sensitive groups including children, pregnant-lactating women and middle-aged & elderly people.
Freely compoundable with vitamin D, vitamin K2, calcium, zinc, iron, B-group vitamins, sugar alcohols and dietary fibre to exert synergistic physiological functions and adapt to multi-vitamin-mineral compound formulas.
Suitable for powder products, compressed candies, solid beverages, weakly-acid drinks and other dosage forms. Strongly-alkaline environments shall be avoided during production to prevent chelate-structure destruction and magnesium-salt precipitation.
Good compatibility with conventional food-system ingredients, rarely triggers abnormal reactions with proteins and colloids. Applicable to baked goods, meal-replacement powders, reconstitutable powders, functional snacks and many other product categories.
Magnesium Citrate is a safe and compliant organic-magnesium nutritional fortifier with high human-body adaptability and multiple physiological values:
Supplies bio-available magnesium for human body, participates in bone mineralisation, works synergistically with calcium to sustain bone mineral density and supports normal bone development and maintenance.
Magnesium participates in nerve signal transmission as well as muscle contraction and relaxation. It helps soothe the body and maintains normal nerve excitability and muscle functions.
As a coenzyme component for multiple metabolic enzymes, it takes part in human energy anabolism and ensures normal operation of basic bodily physiological activities.
Low digestive-tract irritation. Adaptable to long-term nutritional-conditioning scenarios including magnesium supplementation for adolescent growth, nutritional supply for pregnant-lactating women and daily dietary magnesium intake for middle-aged & elderly groups.
➢Dairy Products
Milk powders & reconstituted milk powders: Magnesium nutritional fortification, mitigates bitter-astringent taste of magnesium salts and stabilises dairy-system flavour.
Plant-protein beverages: Compatible with neutral and weakly-acid systems, reduces sensory deterioration induced by magnesium ions.
➢Special-Diet Foods & Solid Beverages
Foods for special medical purposes & meal-replacement powders: Highly-adaptable organic-magnesium source compounded with multi-vitamins and minerals.
Solid beverages: Good powder flowability, suitable for reconstitutable magnesium-supplement formulas.
➢Cereal & Bakery Products
Cereal flakes & cereal powders: Mineral fortification with uniform powder dispersion and good reconstitution stability.
Bread, biscuits, puffed foods: Stable under high-temperature processing to meet product magnesium-nutrient-content requirements.
➢Confectionery & Snacks
Compressed candies, gummies, cereal bars: Magnesium nutritional fortification with low bitter-astringent taste, ideal for functional-snack formulas.
Multi-vitamin-mineral tablets and dietary powders; magnesium-supplement dietary supplements for adolescents, pregnant-lactating women and middle-aged & elderly consumers. It serves as a mainstream organic-magnesium source for high-end magnesium-supplement health-food products.
Organic-chelated magnesium additive for high-grade livestock-poultry, aquaculture and pet feeds. Improves animal magnesium-nutrition level, safeguards nerve-muscle functions and promotes growth.
