1. The Foundation of a Quality Prenatal
Not all prenatal vitamins are created equal. When reviewing a Supplement Facts label, we recommend looking for nutrient amounts that are as close as possible to the following evidence-based targets.
A Note on Folate
Folic acid is the form of folate that has been extensively studied and proven to reduce the risk of neural tube defects during pregnancy. For this reason, we recommend choosing a prenatal vitamin that contains at least 400 mcg of folic acid.
If you have a known MTHFR variant or are concerned about folate metabolism, it is reasonable to add an additional 400 mcg of methylfolate (5-MTHF) to a prenatal vitamin that already contains 400 mcg of folic acid. However, based on current evidence, methylfolate should not replace folic acid during preconception or pregnancy, as it has not been studied as extensively for neural tube defect prevention.
2. Making the Most of Your Prenatal
Keep these foundational principles in mind as you begin selecting your prenatal vitamin:
- Timeline Strategy: Start your prenatal vitamin at least 3 months before trying to conceive. This gives your body time to build up key nutrient stores that support healthy egg development, early fetal growth, and a healthy pregnancy from the very beginning.
- Whole-Food First: Prenatal vitamins are meant to supplement a healthy diet—not replace one. Think of them as a nutritional safety net, helping fill in potential gaps while supporting a healthy pregnancy.
- The Gummy Limitation: Gummy prenatal vitamins can be a convenient option, but they often do not contain iron (which may or may not be needed depending on your individual needs) and may also be missing other important nutrients, such as iodine. If you choose a gummy prenatal vitamin, carefully review the Supplement Facts label to ensure it provides the key nutrients recommended during preconception and pregnancy.
- Managing Constipation: If your prenatal vitamin causes constipation, don't stop taking it without first discussing alternatives with your Beyond Care provider. Instead, we recommend managing constipation proactively by staying well hydrated, increasing your dietary fiber intake, remaining physically active, and using a stool softener if needed. If symptoms persist, switching to a prenatal vitamin that contains a gentler form of iron, such as iron bisglycinate, may help improve tolerability.

A Note from Our Team
Our goal is to provide you with evidence-based information so you can make informed decisions about your health. Every person and every fertility journey is unique, and the "best" prenatal vitamin depends on your individual health history, laboratory results, diet, and specific nutritional needs.
