Extended data
CPP is also a new nutritional product developed with the aim of improving the absorption and utilization rate of calcium. It is one of the bioactive peptide food additives that have been industrialized so far. Compared with VD, CPP has high absorption rate and no toxic side effects, and can improve the absorption rate of other divalent minerals such as zinc and iron. CPP can promote the passive diffusion and absorption of unsaturated calcium in the lower part of small intestine, which is independent of age and VD.
Nano-calcium carbonate, whose fineness is as high as 20,000 meshes, is dozens of times worse than domestic calcium, so it is easier to be absorbed and utilized by human body. We all know that the smaller the calcium supplement particles are, the easier it is to be absorbed by human body. Of course, it can't be achieved only by our chewing. The main reason is that the product uses science and technology to reduce calcium molecules to several microns, which makes it easier to be dissolved and absorbed. It interacts with CPP and D3, and it strengthens the absorption and utilization of calcium.
