The main nutritional supplements after pregnancy are maternal milk powder and some multivitamins, calcium and iron. For pregnant mothers, multivitamins are recommended throughout pregnancy because they are rich in various vitamins needed during pregnancy, such as folic acid, vitamin A, vitamin D, in addition to other minerals, calcium and iron. However, since the demand for iron and calcium increases significantly after the middle of pregnancy, pregnant mothers should take additional calcium and iron preparations in addition to multivitamins. It is important to note that only one cup of maternal milk powder is recommended every day, and if you drink too much every day, it may lead to obesity during pregnancy.
