Caltron’s Oyster Shell Calcium Carbonate Powder

Caltron introduces OY-CAL, its esteemed brand of oyster shell calcium carbonate, solidifying its reputation as a leading manufacturer in the field. We ensure the utmost authenticity and purity in our oyster shell calcium powder, meticulously selecting and processing shells to meet stringent healthcare standards. As one of  Europe’s largest exporters, we maintain top-quality shells to cater to both domestic and international demands.

Our Oyster Shell Calcium Carbonate Powder serves as a versatile ingredient for various pharmaceutical, food, nutraceutical, and cosmetic formulations, including tablets, capsules, suspensions, soft gelatin capsules, and chewable tablets. Recognizing the body’s high demand for calcium, we emphasize natural sources over obsolete rock-based supplements, which may lead to kidney stones over time.

Derived from marine sources, our oyster shells naturally contain vital minerals such as Calcium, Magnesium, and Silica, essential for bodily functions. Through a specialized purification process, we ensure minimal impurities, upholding the integrity of the final product.

Oysto Teratta

Derived from the Oysto Teratta species, Calcium Carbonate powder boasts superior quality. With a highly fibrous nature, the powder exhibits a flaky texture and contains approximately 1.5% magnesium alongside calcium. Despite their fragility, these shells are exceptionally clean. While availability is limited, we’ve secured contracts with excavation teams worldwide to ensure uninterrupted, top-quality supplies throughout the year.

Meta-Calciota

Another abundant species of oyster shell calcium, though with a lower CaCO3 assay compared to Oysto Teratta, serves as a cost-effective alternative to the latter.
