There is more than one kind of food for people to supplement calcium. Usually, food already contains a lot of calcium. The key is insufficient absorption and supplement. There is no need to add and improve a lot. Too much is a waste and unnecessary. I think the main nutritional components of shrimp skin and shrimp skin are the same, but the content is different. If the price of shrimp skin is too high, shrimp skin can be used and the same effect can be achieved.

Hope to adopt
