Vitamin E is a fat-soluble vitamin that is essential for the human body. Vitamin E, also known as tocopherol, has a very important role in maintaining the normal function of the ovaries, as well as having good antioxidant and anti-aging properties. The first thing you can do is to take vitamin E during pregnancy, but it depends on the specific situation: 1. If there is no abnormal performance during pregnancy and no symptoms of miscarriage, there is no need to supplement vitamin E by taking vitamin E pills, etc. You can supplement vitamin E through diet, such as egg yolk, walnuts, peanuts, sunflower seeds and other vegetable oils are rich in vitamin E. 2. If the symptoms of preterm miscarriage appear and the progesterone level is considered insufficient after examination, you can take vitamin E. Vitamin E can improve ovarian function and help to preserve the pregnancy successfully.
