Why does my prenatal need methylated folate?
Methylated folate (5-MTHF) is the active form of folate that your body can use directly, without needing to convert it first, which matters because folate plays a critical role in fetal neural tube development in early pregnancy.† Always consult your healthcare provider before starting any new supplement, especially during pregnancy. Some people have a genetic variation called MTHFR that affects how efficiently they convert standard folic acid, but the CDC notes that people with this variation can still process all types of folate, so this is about knowing what to look for on a label, not something everyone needs to test for1.
Folate, folic acid, and 5-MTHF are not identical
Folate is the general term for vitamin B9, found naturally in foods like leafy greens and legumes. Folic acid is the synthetic form added to fortified foods and most standard supplements. 5-MTHF, or methylated folate, is the active form your cells actually use for DNA synthesis and cell division2. Folic acid has to be converted through several enzymatic steps, including one involving the MTHFR enzyme, before your body can use it the same way.
Research reviewing neural tube defects and folate metabolism has found that folate plays a key role in preventing these defects, and that maternal folate levels in most affected pregnancies were still within what would be considered a "normal" range, underscoring how sensitive this window of development is to nutrient timing and form3.
What the MTHFR variation actually means for you
This is the part that gets oversimplified online. According to the CDC, people with the MTHFR C677T variant have blood folate levels that are only slightly different from people without it, and the agency's guidance is that all women and teens who could become pregnant should get 400 mcg of folic acid daily from supplements, fortified foods, or both, "even if they have an MTHFR C677T gene variant"1. In other words, folic acid intake matters more for blood folate levels than MTHFR status alone.
That does not mean methylated folate isn't worth choosing. It simply means the framing should be "know what to look for on the label" rather than "everyone must test for MTHFR before choosing a prenatal." A study on periconceptional multivitamin use in women with MTHFR polymorphisms found that folate and homocysteine levels varied meaningfully by genotype, which is one reason many OB/GYNs default to methylated folate as a straightforward, broadly compatible choice4.

What to look for on a prenatal label
- "5-MTHF" or "L-5-methyltetrahydrofolate," the active, methylated form
- A stated folate amount in mcg DFE (dietary folate equivalents)
- Whether the prenatal lists folic acid, folate, or methylated folate specifically, since these are not interchangeable terms on a label
What this looks like in practice
Our prenatal with methylated folate and gentle iron, Total Prenatal is formulated with methylated folate (5-MTHF) to support healthy fetal neural tube development, along with choline, non-constipating iron, and algae-sourced DHA.† Total Prenatal, formulated for first-trimester sensitivity, is designed to be taken from preconception through breastfeeding.
"Every mom deserves to understand what's actually in her prenatal, not just trust a label because it says 'prenatal' on the front," says Amy Suzanne Upchurch, Founder and CEO of Pink Stork.

Frequently asked questions
What is the difference between folate, folic acid, and methylated folate?
Folate is the general nutrient. Folic acid is the synthetic form in most fortified foods and standard supplements. 5-MTHF, or methylated folate, is the active form your body uses directly without additional conversion steps2.
Do I need to get tested for MTHFR before choosing a prenatal?
Not necessarily. The CDC notes that people with the common MTHFR C677T variant can still process all types of folate, and the daily folic acid recommendation applies regardless of variant status1.
Why is folate so important in early pregnancy specifically?
Folate plays a key role in neural tube development, which occurs very early in pregnancy, often before many women know they are pregnant3.
Does Total Prenatal include DHA as well?
Yes. Total Prenatal includes algae-sourced DHA to support healthy fetal brain and eye development, in addition to methylated folate, choline, and gentle iron.†
When should I start taking a prenatal with methylated folate?
Many providers recommend starting a prenatal vitamin before conception, since neural tube development begins very early in pregnancy. Talk with your healthcare provider about timing that's right for you.
