When you’re considering starting a family or if you’ve just found out you’re pregnant, one of the first things to consider is to start taking prenatal vitamins. They provide essential nutrients like folic acid, iron, and calcium that are vital for your baby’s development and can help prevent congenital disabilities. 

Prenatal vitamins support your health during pregnancy, helping to fill any gaps in your diet. This article discusses everything you need to know about prenatal vitamins.

Ingredients to Watch out for in Prenatal Vitamins

During pregnancy, the body requires specific minerals to ensure the health of both you and your developing baby. While there isn’t a universal standard for prenatal vitamins ingredients, it should include essential nutrients such as:

  • Folic acid: 400 micrograms (mcg) 

  • Vitamin D: 600 international units (IU) 

  • Calcium: 1,000 milligrams (mg) 

  • Vitamin C: 80 mg  

  • Thiamine: 1.4 mg 

  • Riboflavin: 1.4 mg
     
  • Niacin: 18 mg  

  • Vitamin B12: 2.6 mcg 

  • Vitamin B6: 1.9 mg

  • Vitamin E: 15 mg 
     
  • Zinc: 11 mg 

  • Iron: 27 mg 

  • Vitamin A: 770 mcg

When selecting pregnancy vitamins, it’s essential to check their expiration date to ensure they are not expired or nearing expiration. It’s important to assess the brand reputation, whether the vitamins undergo independent testing, and if the ingredients fulfill your nutritional requirements. 

If you’re uncertain about the quality of prenatal vitamins or need guidance, it’s advisable to consult your doctor for recommendations on trusted brands.

Benefits of Prenatal Vitamins

Taking prenatal vitamins may reduce the risk of a child developing rickets, a condition marked by weakened and softened bones due to vitamin D deficiency. 

Vitamin D is vital for calcium and phosphorus absorption, crucial for bone health. Inadequate vitamin D during pregnancy can lead to a baby born with deficiency, increasing the risk of rickets, abnormal bone growth, and delayed development. 

Prenatal vitamins containing vitamin D can help ensure an adequate supply, thus helping to prevent these complications.

Adequate intake of the B vitamin folic acid, both before conceiving and early in pregnancy, significantly lowers the risk of your child developing neural tube defects like spina bifida (cleft spine) and anencephaly (improper brain and skull bone development).

Ensuring an adequate intake of calcium during pregnancy helps safeguard your health from the impacts of calcium deficiency. Sufficient calcium levels can lower preeclampsia and hypertension (high blood pressure) risk.

 If your diet lacks calcium during pregnancy, your developing baby may extract it from your bones, potentially compromising your future health. Prenatal vitamins can assist in meeting some of your daily calcium requirements, thus supporting your overall health during pregnancy.

Taking folic acid supplements during pregnancy may potentially decrease the chances of a baby being born with congenital disabilities like cleft lip, cleft palate, or heart defects.

Consuming adequate calcium is essential for your child’s growth and development. Women aged 19 and older should aim for 1,000 mg of calcium daily before, during, and after pregnancy, while those 18 and younger should aim for 1,300 mg.

Calcium is crucial for your baby’s development of strong teeth and bones, a healthy heart, nerves, and muscles, and maintaining normal heart rhythm and blood-clotting functions.

Ensuring adequate intake of folic acid early in pregnancy may decrease your chances of developing preeclampsia, a serious condition marked by high blood pressure, fluid retention, and excessive protein in the urine.

In severe instances of preclampsia, when blood pressure reaches dangerous levels, emergency C-sections might be necessary.

During pregnancy, women require significantly more iron, about double the amount compared to before conception. Iron is essential for producing haemoglobin, which carries oxygen in the blood for you and your baby during pregnancy. It facilitates the transfer of oxygen from your lungs to your baby’s body and the rest of your body.

Taking prenatal vitamins containing iron can help prevent iron deficiency anaemia, a condition characterized by severe fatigue and other symptoms, by ensuring an adequate supply of this vital nutrient.

Preventing iron-deficiency anaemia decreases the likelihood of delivering prematurely, having a low birth weight baby, and experiencing infant mortality.

Iodine is crucial in maintaining healthy thyroid function during pregnancy. Insufficient iodine levels can lead to serious consequences, including miscarriage or stillbirth, and can adversely affect a baby’s development. 

Inadequate iodine intake can result in stunted physical growth, severe mental disabilities, and deafness in the baby. Therefore, ensuring sufficient iodine intake is essential to support optimal fetal development and prevent these adverse outcomes.

Side Effects of Prenatal Vitamins

Just like anything you ingest, prenatal vitamins can potentially cause side effects. While these effects are generally mild, they can impact various body parts. Additionally, taking prenatal vitamins might exacerbate some of the symptoms you’re already experiencing due to pregnancy.

Prenatal vitamins can affect the digestive system, leading to nausea, constipation, stomach cramps, bloating, and gas. These side effects can occur due to the concentration of certain nutrients in the vitamins or individual sensitivities to specific ingredients. 

These skin and hair are areas where some women may experience side effects from prenatal vitamins. Hair loss, skin dryness and itchiness, easy bruising, or even skin rashes can occur. These effects may result from changes in hormone levels, reactions to specific vitamins or minerals in prenatal supplements, or individual sensitivities to certain ingredients. 

In some cases, prenatal vitamins may affect the mouth, leading to teeth staining and sore teeth and gums. These side effects can occur due to certain vitamin ingredients or changes in saliva composition. Teeth staining may result from the iron content in prenatal vitamins or other minerals in the formulation. Sore teeth and gums may be due to increased sensitivity or irritation caused by the vitamins. 

Tips to Manage Prenatal Vitamins Side Effects

The benefits of taking prenatal vitamins are generally considered to outweigh the potential side effects, especially when taken as directed by a healthcare provider. 

Prenatal vitamins are crucial in supporting maternal health and fetal development during pregnancy. However, it’s important to consult a doctor to determine the most suitable prenatal vitamins formulation for your and your baby’s needs.

To minimize or avoid side effects from prenatal vitamins, consider the following tips:

  • Take prenatal vitamins with food, as consuming prenatal vitamins with a meal or snack can help reduce the likelihood of digestive discomfort.

  • Consume a full glass of water with your prenatal vitamins to help it go smoothly.

  • Take the prenatal vitamins; do not chew, cut, break, crush, or open it.

  • Don’t take other multivitamins, supplements, or herbal remedies while consuming prenatal vitamins, particularly during pregnancy.

  • Consistently take your prenatal vitamins as directed, ensuring you adhere to the prescribed dosage.

  • If taking the full dose of prenatal vitamins at once causes discomfort, consider splitting the dose throughout the day as your healthcare provider recommends.

  • Some prenatal vitamins come in different formulations or varying levels of certain nutrients. Discuss your specific needs and preferences with your doctor to find the best option.

Risk of not Taking Prenatal Vitamins

If you don’t get enough vitamins, it can raise the risk of various health problems during pregnancy. These complications may include anaemia, a condition where you don’t have enough red blood cells to carry oxygen to your body’s tissues. 

Preeclampsia is another concern, characterized by high blood pressure and signs of organ damage. Insufficient vitamins intake could also increase the chances of miscarriage or stillbirth, premature birth, and having a baby with low birth weight. 

Additionally, insufficient vitamins may elevate the risk of neural tube defects, which affect the baby’s brain, spine, or spinal cord and could lead to developmental delays later on.
