Prenatal Vitamins And Laxatives: What's The Link?

While prenatal vitamins are recommended for all pregnant women, they can cause some side effects, including constipation due to their iron content. Some women have also reported experiencing diarrhea after taking prenatal vitamins, which may be due to the presence of laxatives in certain brands. Nature Made Prenatals, for example, contain Polyethylene Glycol, which is equivalent to Miralax and acts as a laxative. It's important to consult a doctor if you experience any side effects from prenatal vitamins and to be aware of the ingredients in different brands.

Do prenatal vitamins cause constipation?

Constipation is a common problem during pregnancy. High levels of progesterone slow down the movement of food through the digestive tract, and the growing uterus puts pressure on the rectum, making the passage of stool even more difficult.

Prenatal vitamins can sometimes cause constipation due to the iron they contain. Iron is included in prenatal vitamins to help your body make the red blood cells that carry oxygen to you and your baby. However, it can also slow down digestion and harden stools.

If you suspect that your prenatal vitamins are causing constipation, check the label to see how much iron they contain. Unless you're anaemic, you probably don't need more than 30 milligrams of iron per day. If your prenatal vitamins contain more than this, ask your doctor if you can switch to a different brand or formula with less iron.

To help relieve constipation, it's important to stay hydrated and increase your fibre intake. Aim for at least eight cups (64 ounces) of water per day, and include plenty of fibre-rich foods in your diet, such as whole grains, beans, vegetables and fruit. Remember to increase your fluid intake along with your fibre intake to avoid making constipation worse. Staying active can also help promote regular bowel movements.

What are the side effects of prenatal vitamins?

Prenatal vitamins are a combination of vitamins and mineral supplements designed to support the pregnant woman and her growing baby throughout the pregnancy. They are typically recommended for people who are trying to conceive, are already pregnant, or are breastfeeding. While prenatal vitamins can bridge nutritional gaps, they can also cause some adverse effects.

Some common side effects of prenatal vitamins include:

• Digestive issues: Constipation, nausea, stomach cramps, bloating, and gas. Constipation is often caused by the iron content in prenatal vitamins.
• Skin and hair changes: Dry skin, skin peeling, itchiness, easy bruising, skin rashes, and hair loss. These can be caused by vitamin A or fillers in the vitamins.
• Mouth issues: Teeth staining and sore teeth and gums.
• Other issues: Increased urination, difficulty focusing, confusion, increased mouth watering, strange taste in the mouth, fast or uneven heart rate, and allergic reactions.

It is important to note that the side effects of prenatal vitamins are typically mild and may be similar to symptoms of pregnancy. Additionally, taking too many prenatal vitamins or other supplements can be harmful to both the mother and the baby. Therefore, it is recommended to consult a doctor about the appropriate dosage and to report any serious side effects.

Do prenatal vitamins contain laxatives?

Prenatal vitamins are recommended for all pregnant women, as well as women who are trying to conceive or are breastfeeding. They are important because they supplement a woman's diet and make up for any nutritional deficiencies, ensuring that both mother and baby receive the necessary vitamins and minerals. The most important ingredient in prenatal vitamins is folic acid, a B vitamin that can reduce the risk of serious birth defects of the brain and spinal cord in the baby.

Prenatal vitamins can sometimes cause minor side effects, including digestive discomforts such as constipation, skin and hair changes, and other aches and pains. Constipation is a common complaint, often caused by the iron content in prenatal vitamins. However, it is important to note that prenatal vitamins do not typically contain laxatives. In fact, iron—which is present in prenatal vitamins to help carry oxygen to the mother and baby—can clog up the digestive pipes and lead to constipation.

While prenatal vitamins themselves do not usually contain laxatives, some women may choose to take additional supplements to ease constipation. For example, stool softeners, fiber supplements, and milk of magnesia (magnesium hydroxide) are generally considered safe to use during pregnancy to help with constipation. It is always recommended to consult a doctor before taking any new supplements, as some can have negative side effects or interactions with other medications.

In rare cases, certain brands of prenatal vitamins may include ingredients that have a laxative effect. For example, one person reported that Nature Made Prenatals caused diarrhea, which they attributed to the presence of Polyethylene Glycol, equivalent to Miralax. However, this seems to be an exception rather than the norm, as most prenatal vitamins are more likely to cause constipation due to their iron content.

How to manage the side effects of prenatal vitamins

While prenatal vitamins are important for a healthy pregnancy, they can sometimes cause minor side effects such as digestive discomfort, skin and hair changes, and other aches and pains. Here are some ways to manage these side effects:

Digestive Discomfort

Prenatal vitamins often contain iron, which is important for making red blood cells but can cause constipation. To ease constipation, try the following:

• Drink plenty of water with your prenatal vitamin.
• Increase your fibre intake by consuming whole grains, oats, and fresh fruits and vegetables.
• Incorporate natural prebiotics and probiotics into your diet, such as yogurt, bananas, and onions.
• Talk to your doctor about taking supplements like fish oil and probiotics.
• Switch to a prenatal vitamin with less iron.

Skin and Hair Changes

Skin dryness or peeling may be caused by vitamin A or fillers in prenatal vitamins. If you experience these side effects, consult your doctor about switching to a different brand or type of prenatal vitamin.

Aches, Pains, and Other Changes

Iron, calcium, iodine, and other minerals in prenatal vitamins can lead to side effects such as an increased heart rate, frequent urination, confusion, and more. To manage these side effects:

• Avoid taking other multivitamins, vitamins, supplements, or herbal remedies while taking prenatal vitamins, especially during pregnancy.
• Take prenatal vitamins with food or after a meal to avoid an upset stomach.
• Drink a full glass of water with your prenatal vitamin.
• Swallow the prenatal vitamin whole without chewing, cutting, breaking, crushing, or opening it.
• Consult your doctor if you experience serious side effects or if the side effects persist or worsen.

Remember, it is important to take prenatal vitamins as directed by your doctor, and the benefits of these vitamins typically outweigh the side effects.

What to do if you are constipated while pregnant?

Constipation is a common issue during pregnancy, with up to 2 out of 5 people experiencing it at some point. It can be caused by hormonal changes, medicines or supplements, or a lack of fibre in your diet. If you are experiencing constipation while pregnant, there are several things you can do to find relief:

• Increase your fibre intake: Aim for 25 to 30 grams of fibre-rich foods each day. Fibre softens your stools, making them easier to pass. Good sources of fibre include fruits, vegetables, whole grains, beans, peas, and lentils.
• Drink plenty of water: Aim for eight to 12 cups of water per day. Water helps to soften your stools and keep you hydrated. If you don't like plain water, try low-fat milk, smoothies, tea, or juices with no added sugar.
• Exercise regularly: Get 20 to 30 minutes of moderate exercise three times a week. Walking, swimming, yoga, pilates, and light aerobics are all good options to keep your bowel active.
• Try a different prenatal vitamin: The iron in your prenatal vitamin may be contributing to your constipation. Speak to your healthcare provider about switching to a prenatal vitamin with less iron.
• Make good toileting habits: Go to the toilet as soon as you feel the urge, and try sitting on the toilet for a few minutes after meals, especially breakfast. Use a footstool and lean forward with your back straight when sitting on the toilet.
• Try over-the-counter treatments: If lifestyle changes are not enough, speak to your doctor or pharmacist about over-the-counter treatments, such as fibre supplements or laxatives. Be sure to check with your healthcare provider before taking any new supplements or medications.

Remember, it is always best to consult with your healthcare provider if you are experiencing constipation or any other digestive issues during pregnancy. They can provide personalized advice and recommendations based on your individual needs.
