Are you currently expecting and worried you’re gaining too much weight too quickly? Do you wonder if your prenatal vitamins could be contributing to your weight gain?
It’s never too early to start taking care of your baby, and a prenatal vitamin will get you both off to a healthy start. But are there any risks associated with prenatal vitamins? Could they possibly cause weight gain or any other side effects?
We will discuss why it’s important to take a prenatal vitamin and when you should start taking one. We’ll also consider whether they cause weight gain, and what to do if you’re experiencing sudden weight gain or other side effects possibly from your prenatal vitamins.
Why Take A Prenatal Vitamin?
Proper nutrition is important for you and your baby’s health. Your baby depends on you for all of their nutrition needs, and it’s likely your diet could be lacking in vitamins and minerals needed to support a healthy pregnancy.
Taking a prenatal vitamin will fill those nutritional gaps essential for healthy fetal development. It’s even more important to take a prenatal vitamin if you have any dietary restrictions, health issues, or pregnancy complications (source).
Other benefits of prenatal vitamins include:
- Reduced nausea: Vitamin B6 has been shown to reduce nausea associated with morning sickness. Women who use prenatal vitamins before conception tend to have less nausea in the first trimester than those who don’t.
- Fertility boost: Research proves that taking a prenatal vitamin boosts your chances of conceiving a healthy baby faster.
- Reduced risk of congenital disabilities: The biggest reason to take a prenatal vitamin is to ensure you get enough folic acid. Folic acid drastically reduces the risk of neural tube defects in your growing baby (source).
Can’t I Just Take A Multivitamin?
Prenatal vitamins are specifically formulated to meet you and your growing baby’s nutritional needs, whereas a multivitamin will only meet the needs of your body.
Pregnancy increases your daily intake requirement for vitamins and minerals to support proper fetal development. Prenatal vitamins typically provide higher doses of folic acid (folate or folate supplements) which help prevent neural tube defects. They also supply iron which prevents anemia and supports baby’s development, and calcium to support bone development.
Most prenatal vitamins also contain DHA (docosahexaenoic acid) to support the development of the baby’s brain, eyes, and nervous system.
When Should I Start Taking Them?
Healthcare professionals recommend starting a prenatal vitamin three months before you conceive to prepare your body to grow a baby. However, we all know pregnancies aren’t always planned. So if you were just surprised with a positive pregnancy test, start taking a prenatal vitamin right away.
Will They Make Me Gain Weight?
No study can prove prenatal vitamins make you gain weight. Most pregnant women gain about 25-35 pounds throughout their pregnancy whether they use a prenatal vitamin or not. And since vitamins contain zero calories, the weight gain is likely just due to the pregnancy itself.
But Why The Sudden Weight Gain?
If you experience sudden weight gain at any point throughout your pregnancy, visit your doctor as soon as possible. This is a common sign of preeclampsia (source).
Preeclampsia is nothing to mess with. It can have severe effects for both you and your baby, such as low birth weight, miscarriage, stillbirth, seizures, and even maternal death.
Other Side Effects Of Prenatal Vitamins
There is no way to tell if prenatal vitamins can make you gain weight, but they can cause other minor side effects for some women, such as:
- Nausea and vomiting.
- Constipation or diarrhea.
- Dark stools.
- Metallic taste.
- Loss of appetite.
- Bright yellow or green coloration in urine.
However, most of these side effects are symptoms common with pregnancy, so it can be difficult to determine if it is truly the prenatal vitamin causing them. Talk with your healthcare provider about any side effects you may have from taking prenatal vitamins (source).
To Sum it Up
Taking a prenatal vitamin will support you and your baby’s health. They’ve even been shown to reduce nausea, boost fertility, and reduce the chances of birth defects. By taking a prenatal vitamin 3 months before planning to conceive, you will receive enough folic acid, calcium, and iron to support a growing baby.
Although prenatal vitamins can cause constipation, bloating, and other minor side effects for some women, there is no definitive proof they can cause weight gain. Because they contain zero calories, your weight gain is most likely just from the pregnancy itself.
