The high-purity, low-lead and low-arsenic calcium carbonate products are characterized by high purity and extremely low impurities and lead and arsenic. During the application process, the interference of trace element complexation is avoided, ensuring that the taste and flavor of the product remain unchanged.
The purity of calcium carbonate is high and the heavy metal contents are low: iron:≤20ppm, manganese:≤0.5ppm, Lead:0.1ppm, Arsenic: 0.1ppm.Lead (Pb), cadmium (Cd), arsenic (As), and mercury (Hg) are harmful heavy metals that can pose significant health risks when consumed even in small amounts. High-purity calcium carbonate undergoes rigorous testing and purification to ensure that the content of these heavy metals is well below the permissible limits, usually below 0.1 ppm (part per million) for lead and 0.1ppm for arsenicThis low heavy metal content makes the product safe for use in sensitive applications such as baby food, pharmaceuticals, and dietary supplements.

1. Safety and Compliance
One of the primary advantages of high-purity calcium carbonate with low heavy metal content is its safety profile. By minimizing harmful contaminants such as lead, cadmium, and mercury, this type of calcium carbonate complies with strict food safety regulations and ensures that it is safe for long-term consumption, even in vulnerable populations like children and pregnant women.
2. Better Absorption and Efficacy
The fine particle size and high purity of this calcium carbonate make it more bioavailable, meaning it is easier for the body to absorb and utilize. This results in better efficacy in calcium supplementation and food fortification, helping to prevent calcium deficiency more effectively.
3. Versatility in Applications
The high purity and low impurity levels make calcium carbonate suitable for a wide range of applications, including food products, pharmaceuticals, and cosmetics. Its versatility allows manufacturers to create high-quality products that meet both consumer needs and regulatory requirements.
