It is important to take vitamins during pregnancy, either through diet or through medication. In the diet, it is mainly through eating fresh fruits and vegetables that vitamins can be supplemented, not only to strengthen the body’s resistance, but also to facilitate the normal growth and development of the fetus. In the clinical situation, if the expected effect cannot be achieved through diet, it is also recommended to take oral multivitamins for supplementation, for example, Jin Shier Kang is commonly used in clinical practice, which can supplement multivitamins, improve the immunity of pregnant women, enable the normal growth and development of the fetus, and provide the necessities for the growth of the fetus. When supplementing vitamins in the diet, it is best not to eat cold fruits, such as eating less cold fruits like watermelon and pear during pregnancy, so as not to cause discomfort.
