Product Features
The purity of the product, calcium and phosphorus ratio appropriate to ensure a higher degree of its biological effects. Phosphorus content greater than 22% of the products, their biological effects better.
This unique high-tech companies use technology to make our products crystallization, high purity and its harmful impurities significantly below
standards:HG28611997
Drying process advanced products, products with low free water under the premise that the product does not lose crystallization of water, avoid the product in the drying process for the loss of water caused by crystallization of biological effects of the reduction.
