The Benefits of Prenatal Multivitamins for Pregnancy

Written by: Biostime Nutrition

The journey to motherhood is an extraordinary one, filled with excitement and anticipation. During this time, your body undergoes rapid changes, and has different nutritional needs to ensure the health of both you and your baby. 

While a balanced diet is a great way to make sure you get all the essential nutrients, pregnancy multivitamins can also play a key role in your pregnancy journey. Here’s everything you need to know about these supplements including what they are, multivitamins benefits and how they work. 

What are pregnancy supplements?

Pregnancy supplements, also known as prenatal vitamins, are vitamins that are designed to support the health of the mother and baby during pregnancy. These supplements are formulated with specific vitamins and minerals to ensure that both the mother and baby are getting the necessary nutrients they require during this important time.

When preparing for pregnancy, its recommended that women take preconception multivitamins and transition to a pregnancy specific or prenatal multivitamin once they conceive. 

Why are vitamins important during pregnancy? 

Pregnancy places new pressures and demands on your body, creating extra demand for calories and certain nutrients. Good nutrition can help keep both you and your baby healthy throughout pregnancy1. However it can be difficult to obtain sufficient amounts of certain nutrients from diet alone. 

For instance, pregnancy increases your need for folate (or folic acid) as this helps prevent neural tube defects in your growing baby2, while a higher intake of iron is also vital to support the development of both the placenta and the baby3.DHA is another key vitamin, helping to develop a range of things from your baby’s nervous system to their overall growth and development4. Omega-3 fatty acids are another essential nutrient during pregnancy with numerous benefits, including healthy fetal brain and eye development. 

How pregnancy vitamins support your body?

Vitamins and minerals play an important role in a range of physiological functions and are even more important when you fall pregnant. During pregnancy, your body needs more of these vitamins and minerals to support both you and your growing baby. Including things like calcium, folate and iron5. Prenatal supplements are formulated specifically for women who are pregnant with nutrients and vitamins that are crucial for a healthy pregnancy and fetal development, helping to bridge any nutritional gaps.

What are the benefits of taking multivitamins during pregnancy?

One of the key benefits of taking a pregnancy multivitamin is that they can help fill any nutritional gaps in your diet if you fail to consume adequate nutrients in your daily diet ensuring that you don't miss out on nutrients that are essential for a healthy pregnancy and optimal development for your baby. Aside from supporting your overall health, there are plenty of benefits from taking a prenatal vitamin. Let’s take a closer look.
