The HuberCal® Oyster Difference.  Genuine.

Trust the Market Leader.  Insist on Huber Health & Nutrition Authenticity.

HuberCal® Oyster Shell calcium carbonate is produced from shells naturally-harvested from undersea beds in the San Francisco Bay and are believed to be thousands of years old.  Huber Health & Nutrition sources the high purity, genuine shells from a domestic supplier.

While calcium carbonate suppliers claim to offer oyster shell ingredients, some simply offer naturally mined limestone powder or other types of shells.  Take the Huber Health & Nutrition Oyster Shell challenge.  The photo shows calcium supplement tablets broken open.  The tablet on the right is a genuine oyster shell calcium supplement made with oyster shell ingredients supplied by Huber Health & Nutrition.  The tablet on the left is made with a competitor's ingredients and is also marketed as a oyster shell tablet.  Ask yourself:  Have you ever seen a white oyster shell?

When all is said and done, Huber Health & Nutrition simply offers a higher standard of purity and quality with its HuberCal oyster shells.  They go through a rigorous screening and testing process and exclusive double-was technology to ensure you only get the highest quality formulations.  Insist on Huber Oyster Shell authenticity in your formulation.
