Search “best supplements to get pregnant” and you’ll quickly hit a debate: folic acid or methylfolate? Some brands charge more for “active” folate, and people with an MTHFR result often feel they must switch. Here’s what the public-health guidance actually says, how to read the label, and how to avoid paying for the same nutrient three times.
This is educational, not medical advice. For the full buying picture, see our guide to fertility supplements to get pregnant.
1. What the guidance says before conception
The CDC recommends that anyone who could become pregnant get 400 mcg of folic acid every day, starting at least one month before conception, to help lower the risk of neural tube defects. Health Canada gives similar advice (a daily multivitamin with 0.4 mg folic acid). Folic acid is the form used in the studies behind this recommendation — which is why most prenatals use it. Your doctor may recommend a higher dose in specific situations, such as a previous pregnancy affected by a neural tube defect.
2. Folic acid vs methylfolate: the honest difference
| Folic acid | Methylfolate (5-MTHF) | |
|---|---|---|
| Form | Synthetic form used in fortified foods and most prenatals | A form of folate the body uses directly |
| Evidence for NTD prevention | The form used in the key studies and public-health advice | Less direct research for this purpose |
| Cost | Usually lower | Often marketed as premium |
| Who might choose it | Most people | People whose doctor suggests it |
About MTHFR: common MTHFR variants are very widespread. The CDC states that people with these common variants can process folic acid and should follow the same 400 mcg recommendation. If you’ve had a genetic test, ask your doctor which form they prefer for you rather than switching based on marketing.
3. How to read the folate line on a US label
Since the updated Supplement Facts rules, US labels list folate as mcg DFE (Dietary Folate Equivalents). Because folic acid is absorbed well, 400 mcg folic acid = 680 mcg DFE — so a label showing “680 mcg DFE (400 mcg folic acid)” is the standard amount, not an overdose. The NIH Office of Dietary Supplements sets the adult upper limit for folic acid from supplements and fortified foods at 1,000 mcg per day, unless your doctor prescribes more.
4. Don’t pay for folate three times
Folate hides in prenatals, “fertility” multis, B-complexes and even some gummies. A quick audit:
- List every product you take and write down the folate line (mcg DFE and folic acid).
- Add them up — most people only need the amount in one prenatal.
- Keep one prenatal as your folate source; avoid a second multivitamin on top.
- Choose any add-on for a different reason, not for more folate.

5. Where an AGO formula fits
Think in layers: prenatal first (folate, iodine, vitamin D), then one TTC formula to support overall reproductive wellness. AGO formulas are designed to sit on top of a prenatal, not replace it.
| Your situation | Often considered |
|---|---|
| TTC, regular cycles | Prenatal + AGO Mom |
| Irregular cycles or hormonal concerns | Prenatal + AGO Mom + AGO Eva |
| Trying as a couple | Add AGO Dad — see fertility supplements for couples |

FAQ
Is methylfolate better than folic acid for getting pregnant?
Public-health guidance from the CDC and Health Canada is based on folic acid, the form used in the key studies. Methylfolate is an option some doctors suggest, but it isn’t required for most people. Ask your doctor which form suits you.
I have an MTHFR variant. Do I need methylfolate?
The CDC states that people with common MTHFR variants can process folic acid and should follow the same 400 mcg daily recommendation. Talk to your doctor about your specific result.
Why does my label say 680 mcg DFE?
US labels list folate as Dietary Folate Equivalents. 400 mcg of folic acid equals 680 mcg DFE, so this is the standard amount.
Can I take too much folic acid?
The NIH sets the adult upper limit for folic acid from supplements and fortified foods at 1,000 mcg per day unless your doctor prescribes more. Add up all your products to stay within it.
Does AGO Mom replace a prenatal?
No. AGO Mom is a dietary supplement designed to support reproductive wellness and is meant to be taken alongside a prenatal. Bring both labels to your doctor.
Do you ship to the US and Canada?
Yes. AGO ships to the US and Canada; the care team can confirm delivery times for your area.
