Why does methylated folate matter if you have the MTHFR gene variant?

Methylated folate (5-MTHF) matters for people with an MTHFR gene variant because it is already in the active form the body uses directly, skipping a conversion step that the MTHFR enzyme normally handles.† Folic acid, the more common form found in many supplements, needs that enzyme to convert it into a usable form first. If that conversion runs less efficiently for you, a prenatal built with methylated folate already active removes that extra step.† It is worth noting that most people with an MTHFR variant can still process folic acid, just potentially less efficiently, so this is about optimizing form, not about folic acid being unsafe.

Always consult your healthcare provider before starting any new supplement, especially during pregnancy, breastfeeding, or while managing a medical condition.

What the MTHFR gene actually does

MTHFR stands for methylenetetrahydrofolate reductase, an enzyme that helps convert folate into the form your cells use for DNA synthesis and methylation processes. According to the CDC, people with a common MTHFR gene variant can still process all types of folate, including folic acid, though folic acid intake itself is actually more important for determining blood folate levels than variant status alone. A 2024 study published in PMC examining prenatal multivitamin use and MTHFR genotype found associations with newborn cord blood DNA methylation patterns, an active area of ongoing research.

Folic acid versus methylated folate

• Folic acid: the synthetic form most common in fortified foods and many supplements; requires enzymatic conversion to become active
• Methylated folate (5-MTHF): the form your body uses directly, without requiring that conversion step†
• Both forms support healthy fetal neural tube development when adequate intake is maintained†

Total Prenatal uses methylated folate as part of its 22-nutrient formula, giving you our prenatal with methylated folate and gentle iron without requiring your body to complete the extra conversion step.† This supports healthy fetal neural tube development and is the bioavailable form of folate the body uses directly.†

Do you need to get tested for MTHFR?

Testing for MTHFR variants is a conversation to have with your provider, not a decision to make from a TikTok video. Some providers order genetic testing when there is a personal or family history that warrants it; many others focus on ensuring adequate folate intake regardless of genotype, since the CDC notes folic acid intake matters more for blood folate levels than variant status alone.

"So many women come to me feeling like they did something wrong because a supplement did not agree with their body. That is not a failure of will, it is biology. Understanding your own body is part of honoring the journey God gave you."

— Amy Suzanne Upchurch, Founder and CEO of Pink Stork

If you are also navigating the transition from trying to conceive into pregnancy, Pink Stork Premium Fertility Gummies, formulated for preconception nutrition also uses methylated folate (L-5-MTHF), so the nutrient form stays consistent as you move from preconception into your prenatal routine.†

Pink Stork's full product line is third-party tested at ISO 17025 accredited labs and manufactured in cGMP-certified facilities.

Frequently asked questions

What is the MTHFR gene variant?

MTHFR is an enzyme that helps convert folate into its active form. Common gene variants can reduce how efficiently this enzyme works, though most carriers can still process folic acid, according to the CDC.

Is folic acid unsafe if I have an MTHFR variant?

No. The CDC notes that people with an MTHFR variant can still process folic acid. Methylated folate is simply an alternative form that skips a conversion step some people's bodies handle less efficiently.

Should everyone take methylated folate instead of folic acid?

Not necessarily. Both forms can support healthy folate status. Talk to your provider about which form makes sense for you.

Can I find out if I have an MTHFR variant?

Genetic testing is available and is a conversation to have with your healthcare provider, who can help you decide if testing is relevant to your situation.

Does Total Prenatal contain methylated folate?

Yes. Total Prenatal uses methylated folate (5-MTHF) as part of its 22-nutrient formula, supporting healthy fetal neural tube development.†
