What is the difference between casein and casein phosphopeptide?

Casein is the main protein in the milk of mammals including cows, goats and human beings, and Casein Phosphopeptide is a biologically active peptide produced by biotechnology using cow’s milk casein as raw material.
More precisely, casein phosphopeptide is made from casein hydrolyzed by pancreatic enzyme or trypsin and refined and purified. Casein phosphopeptide is used in health and nutritional products to promote the absorption of iron, calcium and zinc. Some studies have shown that casein phosphopeptide has the effect of preventing osteoporosis by reducing the destruction of bone by osteoclasts and inhibiting the resorption of bone formation.
Casein also has the role of regulating blood pressure, regulating blood lipid function, but also to prevent iron deficiency anemia and magnesium deficiency neuritis, the human body has a certain regulatory effect.
It is recommended to take it under the guidance of a doctor.
