Prevention
By Mayo Clinic staffThere's no proven way to prevent morning sickness. Before conception, however, it may help to take prenatal vitamins. Several older studies suggest that women who take multivitamins at the time of conception and during early pregnancy are less likely to experience severe morning sickness. The folic acid in prenatal vitamins also helps prevent neural tube defects, such as spina bifida.
