Huber Nutrition Calcium

Huber Specialty Minerals is the manufacturer behind HuberCal®, a line of naturally pure ground calcium carbonate products designed for use in dietary supplementation, food fortification, pharmaceutical applications, antacids, and granulations. Operating under the broader J.M. Huber Corporation umbrella, the specialty minerals division produces calcium carbonate from high-purity natural sources at its manufacturing facility in Quincy, Illinois. The HuberCal® product line is specifically engineered to serve formulators in the health, nutrition, and pharmaceutical sectors who require a cost-effective yet high-quality calcium source as an alternative to precipitated calcium carbonate.

HuberCal® ground calcium carbonate is distinguished by its exceptional purity, demonstrated low levels of lead and arsenic impurities, low abrasivity that extends processing equipment life, and particle-size versatility that allows formulators to optimize texture and mouthfeel in finished products. The product line is available in multiple grades — including 950, 850, 500, 250, and 150 micron median particle sizes — each with distinct surface area, bulk density, and screen residue characteristics to suit a wide range of application requirements. This particle-size flexibility makes HuberCal® suitable for tablet granulations, powdered dietary supplements, fortified foods, and antacid formulations alike.

Independent analysis has validated the performance advantages of HuberCal® powder versus precipitated calcium carbonate, confirming that formulators do not need to sacrifice quality for economics. The manufacturing and production facilities associated with Huber's ground calcium carbonate operations are certified to ISO standards, underscoring the company's commitment to consistent quality and process control across its global operations. Additional Huber business units operate ISO-certified facilities in North America and Europe, covering ground calcium carbonate as well as fire retardant additives.

The company serves a broad range of industrial and specialty markets through its various divisions, with the health and nutrition segment focused on ingredient supply to dietary supplement manufacturers, food and beverage producers, and pharmaceutical companies. Its product finder and sample request infrastructure indicate active engagement with B2B formulators and procurement teams seeking qualified calcium carbonate suppliers for large-scale production. Huber Specialty Minerals represents a reliable, technically supported source of functional mineral ingredients for CPG and pharmaceutical supply chains.
