Magnesium Citrate Granular Pure (Mg 14.5%-16.4%)

Magnesium Citrate Granular Pure is a highly bioavailable organic magnesium salt supplied as white, irregular granules. Magnesium citrate is the reference form of magnesium for absorption: the mineral is bound to citric acid, which promotes solubility and gentle uptake in the digestive tract. This granular grade is engineered for direct-compression tableting, with a particle structure that flows freely, compresses cleanly and holds hardness without sticking or capping. It supports energy production, nerve transmission, muscle relaxation and bone health - the core benefits buyers expect from a magnesium supplement. Produced from citric acid and magnesium hydroxide under USP specifications, the product is free of residual solvents and carries a two-year shelf life, making it a dependable choice for high-volume supplement manufacturing. It is packed in 25 kg bags and keeps for two years stored on pallets in shaded, cool, dry, ventilated warehouses. The granulation is produced from citric acid and magnesium hydroxide, with no residual solvents. In practice the granules compress directly into hard tablets without granulation steps, keeping production simple and fast. They also suit effervescent blends where citric acid is already part of the formula. Every batch is released against a full quality panel covering appearance, purity, heavy metals and microbiology, so each shipment arrives with documented conformity and traceable batch records. How Magnesium Citrate works: magnesium bound to citric acid forms a salt with high water solubility, which is the basis of its reputation as one of the most absorbable magnesium forms. In the digestive tract the citrate complex releases magnesium gently, avoiding the laxative effect associated with magnesium oxide. Magnesium itself participates in hundreds of enzymatic reactions, supporting energy production, nerve transmission, muscle relaxation and bone health - the core benefits supplement buyers seek. Practical guidance: the granular grade is designed for direct compression - it flows freely, compresses into hard tablets and disintegrates cleanly; in effervescent tablets the citrate naturally partners with citric acid systems; in drink mixes the granular form dissolves quickly in warm water; and in food fortification it blends into dry mixes for magnesium-enriched products. Quality assurance: produced from citric acid and magnesium hydroxide under USP specifications, free of residual solvents, with magnesium content, pH, heavy metals and microbiology tested per batch and documented. Packed in 25 kg bags with a two-year shelf life in cool, dry storage. This pure granular citrate gives supplement manufacturers a single-ingredient magnesium solution that performs on the press and in the body. Specification highlights: it is packed in 25kg/bag with a minimum order quantity of 1000kg. Certificates of analysis accompany every shipment, and sample supply, specification customization and flexible payment terms are available for qualified buyers, supported by the standardized seven-step service process from inquiry to after-sales support. Documented quality from batch to batch: every production lot is verified against the full specification - identity, purity, heavy metals and microbiology - before release, and the resulting certificates and batch records travel with each shipment to support qualification and audit. Raw materials are sourced to defined standards, storage follows the conditions stated in the specification, and the product ships in its original, intact packaging. Shelf life and storage requirements are clearly documented, so purchasing, warehouse and quality teams all work from the same reference. This repeatable quality system is what makes the grade dependable for multi-year supply agreements.

Applications

It is ideal for direct-compression magnesium tablets, including energy, sleep and muscle-recovery formulas. Supplement makers use it in effervescent tablets and drink powders where solubility matters, and food fortification uses it to add magnesium to beverages, dairy and nutrition bars. Sports and wellness brands choose it for electrolyte and cramp-relief products.

Advantages

As a pure granular citrate, it gives tablet manufacturers the twin advantages of high absorption claims and smooth direct-compression processing in one ingredient - no blending aids required. Its organic salt form is gentle on the stomach and less likely to cause laxative effects than inorganic magnesium sources. USP compliance, a two-year shelf life and reliable 25 kg supply make it a practical core mineral for supplement production.
