You don’t need to take soda tablets to prepare for pregnancy, but you do need to take a folic acid supplement. Soda is the common name for sodium carbonate, mainly for industrial use. Baking soda is the common name for sodium bicarbonate, which is mainly used to alkalize urine, which can promote the elimination of acids, and can also neutralize and buffer stomach acid, which is used for hyperacidity. Therefore do not take soda tablets in preparation for pregnancy. During the preparation period, pay attention to a healthy diet, do not eat cold and spicy stimulating food, quit smoking and alcohol, regular life, do not stay up late. Women need to take folic acid supplements during pregnancy preparation, mainly for the prevention of neural tube malformations in the fetus, as well as the prevention of anemia in pregnant women and the reduction of the risk of miscarriage. During pregnancy, pregnant women’s need for folic acid will be much higher than that of the general population, but it is not possible to fully obtain the intake of folic acid through diet, and only through oral medication to supplement sufficient folic acid. Therefore, women need to take folic acid tablets as prescribed by their doctors from three months before pregnancy to the first three months after pregnancy, and can also undergo genetic testing of folic acid metabolism for further guidance on how to take folic acid. Before preparing for pregnancy, both men and women need to go to the hospital to do pre-pregnancy checkups under the guidance of a physician to ensure that their bodies are in the best condition to conceive.
