Without this net full of small holes, even if it is supplemented with excessive calcium, it will be lost in vain. The characteristic amino acid hydroxyproline of collagen is a tool for transporting calcium from plasma to bone cells. The bone collagen in bone cells is the binder of hydroxyapatite, and together with hydroxyapatite, it forms the main body of the bone. The production rate of new collagen is lower than the rate of mutation or aging of old collagen. Studies have shown that if collagen is lacking, no amount of calcium supplementation can prevent osteoporosis. Therefore, only by taking in enough collagen that can be combined with calcium can calcium be digested and absorbed faster in the body and can be more effective. It quickly reaches the bones and deposits.
