Oyster calcium is a natural calcium supplement made from oyster shells through processes such as cleaning, calcination, crushing, and purification. Its core component is calcium carbonate (with a content of over 90%), and it is also rich in trace elements like magnesium, zinc, and selenium. Thanks to its unique natural properties and functional advantages, oyster calcium is widely used in fields such as health preservation, food processing, medicine, and agriculture.
I. Core Advantages of Oyster Calcium
Compared with synthetic calcium or other calcium sources, oyster calcium has multi-dimensional advantages, enabling it to occupy an important position in the market:
Natural and Safe with High Biocompatibility Derived from marine oyster shells, oyster calcium is a natural biological calcium source. Its mineral composition bears a certain similarity to the calcium-phosphorus structure in human bones and teeth, making it easier for the human body to recognize and absorb. Its biocompatibility is far superior to that of chemically synthesized calcium.
Nutritious, Providing Both Calcium and Trace Elements In addition to calcium carbonate (its core component), oyster calcium naturally contains a variety of essential trace elements for the human body, including magnesium, zinc, selenium, and strontium. This compound nutritional structure of "calcium + trace elements" allows it to not only supplement calcium but also synergistically regulate human metabolism, giving it more nutritional advantages than single-component synthetic calcium.
Relatively High Absorption Rate After being processed by the calcination process, the calcium carbonate in oyster calcium has a looser crystal structure and improved water solubility. It can quickly dissolve and dissociate into calcium ions in the gastric acid environment, with an absorption rate of 30%-40%.
Environmentally Friendly and Sustainable, Enabling Resource Circulation Oyster shells are the main waste from the seafood processing industry, and random disposal of them can easily cause environmental pollution. By using oyster shells as raw material to produce oyster calcium, this waste is effectively recycled, reducing environmental pressure and achieving the sustainable use of resources.
With its core advantages of "natural safety, diverse nutrition, and environmental sustainability", oyster calcium has expanded from a single calcium supplement to a cross-field functional raw material. It not only meets the needs of human health but also provides green solutions for industries such as food processing, medicine, and agriculture.
