Calcium Carbonate DC95 (36% Ca)

Calcium Carbonate DC95 is a direct-compression grade of calcium carbonate granulated with a small amount of starch binder. The result is white, irregular granules that flow freely, compress into hard tablets and disintegrate predictably - the properties that make DC grades the industry standard for high-dose calcium tablets. Calcium carbonate is the most concentrated and economical source of elemental calcium, and this granulated form overcomes the poor flow and capping problems of plain fine calcium carbonate powder. It is widely used in calcium supplements, multivitamins and antacid tablets. Produced under USP 44 and food-grade specifications with strict purity controls and a two-year shelf life, it is a dependable workhorse for large-scale supplement tableting. Because calcium carbonate neutralizes stomach acid quickly, the grade also suits chewable antacid formats. It is packed in 25 kg bags and keeps for two years in shaded, cool, dry, ventilated warehouses. The granulation combines calcium carbonate with a small starch binder for consistent tablet performance. In practice the granules run on high-speed presses at full speed with consistent weight and hardness, allowing calcium tablets to be produced with simple, low-cost formulas. They also suit chewable formats where crunch is welcome. Batch records and test reports are available for every delivery, supporting buyer qualification, regulatory filing and long-term supply relationships. How DC95 works: calcium carbonate is the most concentrated and economical source of elemental calcium, but its fine powder flows poorly and caps in tablet presses. DC95 solves this by granulating calcium carbonate with a small starch binder, producing white, irregular granules that flow freely, compress into hard tablets and disintegrate predictably. The result is high-dose calcium tablets produced on simple, fast-running lines. Practical guidance: direct-compress calcium tablets and calcium-vitamin D combinations; build bone-health supplements and multivitamin-mineral tablets; produce chewable formats where the chalky bite is welcome; use the granules in antacid products for rapid acid neutralization; and fortify cereals and powdered drinks with granulated calcium. Quality assurance: produced under USP 44 and food-grade specifications with calcium content, heavy metals and microbiology tested per batch, with documentation for every delivery. Packed in 25 kg bags with a two-year shelf life in shaded, cool, dry storage. For supplement manufacturers, DC95 removes the last formulation barrier to high-dose calcium tablets. 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 formulated into direct-compression calcium tablets, calcium-vitamin D combination products and bone-health supplements. Multivitamin and mineral tablets use it as a calcium source with reliable compression behavior. Antacid tablets use its rapid acid-neutralizing property, and food fortification uses the granules in cereals and powdered drinks for calcium enrichment.

Advantages

The DC95 granulation removes the formulation headache of calcium carbonate: it flows, compresses and holds hardness on high-speed presses without capping, letting manufacturers run high-dose calcium tablets with simple, low-cost formulas. Its high calcium density keeps tablets small enough to swallow. USP 44 compliance, a two-year shelf life and steady supply make it the safe default for calcium tableting operations.
