If you’re trying to conceive, you’ve likely heard this advice:
“Make sure you’re taking folic acid.”
And yes — vitamin B9 is essential for a healthy pregnancy.
But here’s what’s often missed:
The form of B9 you take matters.
Because for many women, synthetic folic acid may not be the most supportive — or effective — option for fertility or pregnancy.

Let’s simplify this:
Folic acid = synthetic form (used in most supplements and fortified foods)
Folate = naturally occurring form (found in whole foods)
Your body doesn’t actually use folic acid as-is.
It must first convert it into its active form: methylfolate.
And that conversion step is where things can break down.
When intake is high — especially from both supplements and fortified foods — your body may struggle to fully convert folic acid.
This can lead to a buildup of unmetabolized folic acid, rather than usable folate.
Over time, this may interfere with optimal folate status — rather than support it.
Folate plays a critical role in:
Low or poorly utilized folate has been associated with:
Again — the goal isn’t to avoid folate.
It’s to make sure your body can actually use it.
The MTHFR gene helps convert folate into methylfolate (the active form your body uses).
Variations in this gene are common—and can reduce how efficiently your body performs this conversion.
For some women, this means:
From a fertility perspective, this can impact:
Even without testing, this pathway is often worth supporting.
Keep it simple and actionable:
Look for:
This is the active form your body can use immediately — no conversion required.
Common sources include:
These can significantly increase total intake — without improving absorption or use.
Prioritize whole food sources like:
If you’re trying to conceive or have experienced miscarriage, testing may offer helpful insight.
That said, many practitioners take a “support first” approach — since these strategies are broadly beneficial.
When choosing a supplement, look for:
Think of supplements as support — not a substitute for a nutrient-dense diet.
Here’s the only folate supplement that I recommend.
You will also want a quality prenatal vitamin that does not contain synthetic folic acid. My number one recommendation is the Prenatal Pro Essential Bundle.
This is a comprehensive 30-day supply of three formulas designed to support a healthy pregnancy and fetal development. The Prenatal Pro Essential Bundle contains your prenatal multivitamin, a broad-spectrum multimineral and a high quality omega-3 fish oil, providing potent levels of all necessary vitamins and minerals that play a part in the intricate processes of pregnancy.
Folate is essential for fertility and pregnancy — but the form matters.
A more supportive approach:
Because when your body can actually use the nutrients you’re taking — that’s when things start to shift.
Folate is the natural form of vitamin B9 found in food and plays a critical role in the production of RNA and DNA. This nutrient is especially important for supporting cells and tissues that are growing rapidly, like during infancy, adolescence, and pregnancy. It also works in tandem with vitamin B12 to stimulate the production of red blood cells. Folic acid, on the other hand, is the synthetic, shelf-stable version of folate and is not as readily absorbed or assimilated.
Pregnant women need lots of vitamin B9 to support their growing babies while staying healthy themselves; however, taking folic acid supplements is not the answer. Not only will the synthetic nutrient fail to help mama and baby, but it could actually end up causing more harm than good. If you have the MTHFR (methylenetetrahydrofolate reductase) gene mutation, for example–and roughly 40% of the population does–your body cannot metabolize folic acid at all. Should this be the case, taking supplements that contain folic acid will result in a buildup of the unmetabolized nutrient. Since it would accumulate on the cell receptors that are looking for actual folate, your body will remain deficient even when you consume foods rich in folate because it thinks it already has enough.
There are two ways to increase your folate intake. The first is by consuming lots of folate-rich foods. Examples include dark leafy greens, broccoli, citrus fruits, peas, beans, and lentils. You can also take methylated folate supplements. These are different from folic acid supplements because your body can use the folate in them without having to metabolize it. My favorite source for this kind of folate is in the Prenatal Pro Essential Bundle.
If you’ve been told everything looks normal but you’re still not pregnant — or you have a diagnosis like PCOS, endometriosis, or poor egg quality and still aren’t getting results — you don’t need another supplement or another failed cycle. You need a plan that actually changes the outcome.
The Fertility Code is my 12-week, high-touch fertility program designed to identify the hidden drivers preventing pregnancy and address them — so you can conceive naturally or move into IVF with confidence — without sacrificing another year to confusion, uncertainty, or repeated disappointment.
This is not a course you consume alone. It’s a close-proximity, expert-guided experience. We examine your full history, run the right labs, refine your nutrition and lifestyle, and build a personalized protocol tailored to your body and your timeline. With 1:1 coaching, direct access between calls, lab reviews, evidence-based content, and structured accountability, you stop second-guessing and start moving forward with clarity.
