Why Do Prenatals Make Me Sick

Dec 1, 2024

Prenatal vitamins are one of the most vital components of pregnancy care, as they avail the baby of important building blocks for development. They contain substantial amounts of folic acid, iron, and calcium that are useful in fetal development and the prevention of complications. While having many benefits derived from taking this medication, the majority of persons describe nausea or other digestive problems.

In the case of prenatals, this might be frustrating, as it adds to the symptoms of morning sickness. However, understanding the reasons behind these side effects and learning how to minimize them can make taking prenatals much easier.

Common Reasons Prenatal Vitamins Can Make You Feel Sick

High Iron Content

Iron is an important ingredient in prenatal vitamins, as it helps prevent anemia and assures the baby gets sufficient oxygen. Large doses of iron, however, can be hard on the stomach, causing nausea, constipation, or bloating, especially if your system is not used to processing all that iron.

Iron supplements may irritate the lining of the stomach, especially if taken without food. This commonly presents itself as a queasy feeling shortly after taking the vitamin. In such cases, reducing iron intake or changing the form of intake may alleviate some of these symptoms.

Vitamin Composition

Some prenatal vitamins, particularly those containing B vitamins and zinc, can cause nausea due to their ingredients. While B vitamins are important for energy production and fetal development, they often have an unpleasantly strong taste or smell that can cause nausea for many women.

Zinc is another popular ingredient linked to stomach upset, especially in large measures. While these nutrients are important, they can be difficult to tolerate, especially if sensitive to them.

Timing and Method of Intake

One of the most common culprits behind nausea includes taking prenatal vitamins on an empty stomach. Without food to buffer the impact, the concentrated nutrients can overwhelm your digestive system.

The time of day you take the vitamins also plays a role. Morning dosing conflicts with the natural queasiness many feel during pregnancy, amplifying discomfort. Most often, switching to an evening routine or taking them with a small, balanced meal can alleviate symptoms.

How to Manage Nausea from Prenatal Vitamins

Take with food

The nausea can be greatly reduced by taking your prenatal vitamins with a meal. Food helps to buffer the impact of concentrated nutrients on your stomach. A light, balanced meal with complex carbohydrates and protein is best: whole-grain toast spread with almond butter or scrambled eggs with vegetables are good choices.

Avoid pairing prenatal vitamins with acidic or spicy foods, as they can irritate your stomach further. Morning sickness can amplify nausea from prenatal vitamins, so consider a light snack beforehand if you’re taking them early in the day.

Split Doses

Splitting your prenatal dose into two smaller portions can make all the difference in your body's nutrient intake. Instead of overwhelming the stomach all at once, dividing the dose allows the system to take it in a little more gently.

For example, take half in the morning and take half with dinner. And to make the strategy a bit more convenient, some brands offer divided-dose formulations. This can definitely minimize most side effects such as nausea and bloating while giving your body time to absorb the nutrients it needs.

Switching Prenatal Vitamins

Consider Low-Iron Options

Iron is a frequent offender of nausea associated with prenatal vitamins. You may be able to switch to a low-iron version if your diet already contains iron-rich foods or if your healthcare provider decides you don't need the extra iron.

These alternatives are less likely to irritate your stomach and can still provide other vital nutrients like folic acid and calcium. However, consult your doctor before making the switch to ensure you’re not compromising on your baby’s nutritional needs.

Opt for Gentle Formulations

Some prenatal vitamins are specifically formulated for sensitive stomachs. These gentler formulations may contain more balanced nutrients in lower dosages, which is why they are easier to tolerate. Look for options labeled as "gentle on the stomach" or "for sensitive digestion."

They can also use different, more gentle forms of nutrients, like ferrous bisglycinate for iron, which is known not to irritate the stomach as much. Often, a switch to a more gentle formula can make the prenatal vitamin a comfortable part of your daily regime.

When to Consult Your Doctor

Persistent Symptoms

If the nausea, bloating, or other adverse effects of prenatal vitamins are constant, even after making adjustments, it's time to speak with a healthcare professional. Ongoing discomfort may signal an iron intolerance, vitamin toxicity, or a digestive sensitivity underlying these conditions that could use medical attention on an individualized basis.

Severe symptoms, such as vomiting, extreme fatigue, or noticeable changes in bowel movements, should not be ignored. These could indicate that the body is not tolerating the supplement well, or that it is getting too much of a particular nutrient. A healthcare professional can conduct tests to see what nutrients are in your body and make adjustments as needed to your supplement intake.

Customizing Your Supplement Routine

Health professionals can work out a prenatal supplement regimen tailored for your needs. They might recommend formulations with lower concentrations of some nutrients or suggest splitting your dose to make it easier to tolerate.

If traditional prenatal vitamins continue to cause problems, your doctor may recommend more targeted alternatives, such as folic acid or iron supplements taken separately. That way, you will still get the nutrition you need but won't experience the side effects from one high-dose tablet.

Additional Tips for Taking Prenatals with Less Discomfort

Hydration and Prenatal Intake

For some, nausea is helped by being well-hydrated during the day, and it also aids in the digestion process for prenatal vitamins. Many times, nausea is worse with dehydration, so fluids are important. Setting your supplement alongside a hydrating drink, such as herbal tea or a smoothie, will further ease the digestion process.

Avoid drinking large amounts of water immediately after taking your vitamin, as it might exacerbate queasiness. Sipping slowly and consistently throughout the day is more effective.

Bedtime Dosing

Taking prenatal vitamins at bedtime can be a game-changer for managing side effects. Nausea and bloating are less noticeable when your body is at rest, making evening dosing a practical choice for many.

You can further help minimize stomach upset by pairing your vitamin with a light snack, like crackers or even a banana. Adding the supplement to your nightly routine makes it less interfering in your day and also ensures continuity.
