A woman’s nutritional needs become higher once she becomes pregnant. That’s why there is a greater need for her diet to contain the necessary nutrients, including vitamins and minerals – all achieved through a balanced diet. As for the needs of your growing baby, he or she cannot afford deficiencies of a few nutrients as these are essential in the development of vital organs. It is for this reason that your obstetrician would prescribe you some supplements. It is important to note that while not all pregnancy supplements are necessary, the benefits of giving them should outweigh the risks. That said, DO NOT self-prescribe. Always take supplements only after discussing its safety and dosage with your doctor.

Supplementsi Recommended for Pregnancy

One of the most widely prescribed supplements for pregnant women is Folic acid. Due to its critical role to prevent neural tube defect, folic acid supplementation is recommended even as you prepare to conceive.ii You may not realise it, but your baby’s brain starts developing even before your first prenatal doctor’s visit! 400 mcgii of Folic acid is the usual recommendation, but your doctor may decide to give a higher dose if you fall under a high risk category.

In addition to Folic acid, Iron supplement is also generally prescribed. Iron and folic acid, which support the formation of red blood cells, are especially important during your pregnancy when the volume of your blood increases to carry oxygen and nutrients to your body tissues and your baby. Iron deficiency anemia during pregnancy can lead to complications such as premature birth and low birth weight. The World Health Organization recommends that pregnant women take a daily supplement containing 30 to 60 mg of ironii. If you are a vegetarian, you should take more precaution because you may have increased risk of iron deficiency anemia. If you are diagnosed with anaemia during pregnancy, your doctor may increase your elemental iron dose: 120 mg until your haemoglobin rises to normal.

Another supplement that may commonly be given is Vitamin D, as insufficiency seems to be prevalent even in Asia, as people tend to stay in-door and avoid sun exposure. You should be getting 10 μg (micrograms) of vitamin D every day during your pregnancy. Vitamin D helps your body to absorb two important minerals – calcium and phosphorus – which in turn, supports the development of your baby’s bones and teeth. In addition, it also keeps them strong. If you are not getting enough vitamin D during your pregnancy, it may increase your risk of pregnancy related complications such as pre-eclampsia and low birth weightiii.
