Pregnant women can take appropriate collagen supplements throughout pregnancy because collagen maintains skin elasticity and prevents the development of stretch marks. It can also maintain the integrity of the bone structure, and the normal thickness and toughness of the blood vessel walls, and lower cholesterol and bile acids. But you must be careful in choosing collagen, you must choose the type that matches the type taken during pregnancy. Pregnant women can use collagen to supplement their diet during pregnancy because of anorexia due to pregnancy reactions and the increase in nutrients needed for fetal development, resulting in a large loss of collagen. Of course, collagen can also be supplemented through food, such as you can eat more chicken wings, fish skin, corn, pig’s feet, cow’s feet and cartilage. In addition, pay attention to a certain amount of fresh fruits and vegetables, pay attention to a balanced diet during pregnancy, appropriate physical exercise, and keep a happy mood.
