Pure and Natural Calcium Carbonate. Genuine Oyster Shell.

A passion for serving our customers with the highest quality products and superior technical and customer service has driven us to create a market-leading health & nutrition business. As a producer of both calcium carbonate powders and granulations, we have control over the quality and reliability of our supply chain. With the addition of our Quincy, Illinois, granulation facility, Huber became the only calcium carbonate granulation producer with two manufacturing locations in North America (the other is in Modesto, California), enabling us to serve our markets with unequaled service and dependability.

Natural, pure HuberCal® calcium carbonate is available in powder or granule form – in food and USP grades. HuberCal® genuine oyster shell products are available as food grade granules. Market Leadership 2 • HuberCal® Pure and Natural Calcium Carbonate The addition of Huber’s Quincy, Illinois, calcium carbonate granulation facility is the perfect compliment to the Modesto, California, operation since it’s strategically located for customers in the Midwest and Eastern U.S. This means: • Enhanced Customer Service • Significant Freight Savings • Food Grade and USP Granulations • Dual-Site Production for Security of Supply At Huber’s state-of-the-art Quincy, Illinois, operation, HuberCal® calcium carbonate is granulated to exact specifications (photo above left). HuberCal products are bagged and prepared for shipment (photo above right). Purity and Versatility HuberCal® Pure and Natural Calcium Carbonate • 3 Texture That Makes Great Chewables. Purity That Makes You Confident. When it comes to choosing a calcium carbonate source for antacids, two factors matter most – texture and purity. HuberCal® Elite gives you both. HuberCal Elite calcium carbonate powders and granulations have been shown to outperform other leading calcium carbonates in sensory perception (mouthfeel). Superior texture and high purity are two great reasons why formulators of antacids have come to rely on HuberCal Elite as their trusted source of natural calcium carbonate. Makers of antacids have also come to praise HuberCal for its low abrasivity, which means less wear on processing equipment and tablet tooling, translating into lower production costs and higher throughput.

Demonstrated Low-Lead and Low-Arsenic Impurities Consumers and regulators alike are increasingly concerned with lead and heavy metals ingestion. The HuberCal product family helps formulators to address this concern. Independent analysis has shown HuberCal to offer lower lead and arsenic versus leading competitive natural calcium carbonates. The data below confirms typical lead in HuberCal to be below 100 parts per billion – significantly lower than competitive products. Typical results for arsenic are below 0.1 ppm. All HuberCal grades meet California Proposition 65 requirements. Compendial Compliance HuberCal® FG grades comply with the Food Chemicals Codex requirements. HuberCal® USP grades comply with the U.S. Pharmacopeia (USP) requirements, and HuberCalElite grades comply with the U.S. Pharmacopeia and European and Japanese† Pharmacopoeia requirements.

†HuberCal Elite meeting Japanese Pharmacopoeia available upon special request The HuberCal® Natural Calcium Carbonate Advantage To be confident in your calcium carbonate, you must be satisfied with its quality. Whether you’re fortifying food products, producing other calcium salts or manu- facturing pharmaceutical or dietary supplement dosage forms, your formu- lation begins with a calcium carbonate product that offers extremely high purity. Every time. That’s HuberCal natural calcium carbonate from Huber Health & Nutrition.

HuberCal gives you a higher calcium carbonate assay – typically greater than 99%. This degree of purity is why food companies, calcium salts producers and pharmaceutical and dietary supplement manufacturers have come to rely on HuberCal natural calcium carbonate. Independently Verified Quality Historically, formulators have had to choose between ground calcium carbonate (GCC) for its cost advantage and precipitated calcium carbonate (PCC) for its purity. Now with HuberCal calcium carbonate, formulators can choose a cost-effective product without com- promising quality. Independent analysis has validated the HuberCal quality advantage.

For the granulator, HuberCal provides an overall better value as a source of calcium for supplements and pharm- aceuticals. For manufacturers of calcium salts other than calcium carbonate, HuberCal products offer a high purity, high performance raw material. Benefits HuberCal® pure and natural calcium carbonate offers a combination of outstanding performance, high purity (calcium assay greater than 99%) and exceptional value vs. precipitated calcium carbonate all backed by unsurpassed Huber customer care and technical service.

4 • HuberCal® Pure and Natural Calcium Carbonate Low Acid Insolubles Another measure of the purity of calcium carbonate is the amount of acid insoluble material contained in the product. When pure calcium carbonate reacts with acid, there should be no residue. Depending on the grade, HuberCal® natural calcium carbonate complies with the Food Chemicals Codex and U.S. Pharmacopeia and European and Japanese† Pharmacopoeia requirements for acid insolubles. †HuberCal Elite meeting Japanese Pharmacopoeia available upon special request Superior Sensory Perception Nine out of 10 new food products fail for one reason – failure to integrate sensory data in product testing.1 Huber Health & Nutrition is aware of the importance of texture. That’s why we commissioned an independent lab to perform a comparative sensory analysis of the texture of competing calcium carbonate products in a generic chewable tablet formulation. The results demonstrate our superior sensory performance.

1 Source: Nutrition Business Journal, Volume VII, May/June 2002 Lower Abrasivity Abrasion of equipment is an important concern for those who process calcium carbonate. A comparative test of samples of precipitated calcium carbonate products from the leading supplier shows that the HuberCal calcium carbonate family of products is much less abrasive. Moreover, our customers have confirmed that the lower abrasivity of HuberCal calcium carbonate leads to longer tooling life in their tablet equipment.

HuberCal® Genuine Oyster Shell • 7 The HuberCal® Oyster Shell Difference. Genuine.

Insist on Huber Authenticity. Huber Health & Nutrition offers the nutritional supplement formulator a directly compressible version of HuberCal® oyster shell calcium carbonate, which is harvested directly from undersea beds in the San Francisco Bay. The oysters are believed to be tens of thousands of years old. Supplement Versatility Do You Know Your Source? While calcium carbonate suppliers claim to offer oyster shell ingredients, some have been known to simply offer naturally mined limestone powder or other types of shells. Huber sources high purity, genuine oyster shells directly from a domestic supplier. Break open a calcium supplement that claims to use oyster shell calcium carbonate. If the interior of the tablet is grey, you are most likely looking at genuine oyster shell supplied from Huber Health & Nutrition.

8 • HuberCal® Genuine Oyster Shell Huber’s Higher Standards of Purity and Quality HuberCal® oyster shell granulations go through a rigorous and thorough screening and testing process to ensure you get only the highest quality formulations. A double-wash technology ensures that impurities are removed from the raw oyster shells prior to processing. HuberCal oyster shell products comply with California Proposition 65 standards for lead and offer extremely low levels of lead for genuine oyster shell (Source: West Coast Analytical Laboratory). This is why HuberCal oyster shell calcium carbonate has earned the right to be considered the standard for quality throughout the nutrition industry. HuberCal oyster shell granulations are also offered with standard binder systems that include maltodextrin, acacia gum and combinations of these materials. Granulations using other binder systems and other sources of calcium carbonate are available by special request. Note: Huber Health & Nutrition does not use oyster shells derived from the processing of live oysters.
