Trying to conceive? One of the first supplements you may hear about is folate. But should you take folic acid or methylfolate? Both play an important role in preconception and pregnancy health, but the most suitable form depends on your individual health, medical history and supplement needs.
Many women are unsure which form is right for them, especially if they have heard about the MTHFR gene, recurrent miscarriage, IVF or fertility challenges.
This guide explains the difference between folic acid and methylfolate, why folate matters before pregnancy and when personalised advice may be helpful.
Why is folate important before pregnancy?
Folate is a B vitamin that helps the body produce new cells and DNA. During early pregnancy, cells divide rapidly as the baby’s brain, spinal cord and organs begin to develop.
Adequate folate before conception and during early pregnancy helps support healthy neural tube development and reduces the risk of neural tube defects, including spina bifida.
Because the neural tube develops very early—often before pregnancy is confirmed— folate supplementation is usually recommended before conception rather than waiting until a positive pregnancy test.
What is the difference between folic acid and methylfolate?
Although the terms are often used interchangeably, folic acid and methylfolate are different forms of vitamin B9.
Folic acid
Folic acid is the synthetic form of vitamin B9. It is commonly found in:
- Prenatal vitamins
- Pregnancy supplements
- Fortified breakfast cereals
- Fortified breads and grain products
Folic acid is stable, widely available and has been used in public health programs to help reduce the incidence of neural tube defects.
Methylfolate
Methylfolate, also known as 5-MTHF, is a biologically active form of folate.
It does not require the same conversion steps as folic acid before participating in the body’s folate-dependent processes. Some practitioners may recommend methylfolate for selected patients based on their medical history, blood results, genetics or previous pregnancy outcomes.
Is methylfolate better than folic acid?
The most accurate answer is that it depends on the individual.
For many women planning pregnancy, standard folic acid supplementation remains appropriate and is commonly recommended because it has strong evidence supporting the prevention of neural tube defects.
However, individual assessment may be helpful if you have:
- Recurrent miscarriage
- A previous pregnancy affected by a neural tube defect
- Elevated homocysteine
- A known MTHFR gene variant
- Fertility challenges
- A complex medical history
- Difficulty tolerating standard prenatal supplements
Rather than assuming methylfolate is always superior, it is more useful to determine which form and dose are appropriate for your own health and pregnancy plan.
Unsure which prenatal supplement is right for you?
A personalised preconception consultation can help review your current supplements, diet, fertility history, medications and relevant blood results.
What is the MTHFR gene?
The MTHFR gene provides instructions for producing an enzyme involved in folate metabolism and the processing of homocysteine.
Some people carry common MTHFR gene variants that may reduce the activity of this enzyme. This topic has attracted significant attention online, but it has also created confusion.
Having an MTHFR variant does not automatically mean:
- You cannot become pregnant
- You cannot absorb folate
- You must avoid all folic acid
- You will experience miscarriage
- You require high-dose methylfolate
MTHFR status is only one part of the picture. Your practitioner may also consider:
- Homocysteine levels
- Vitamin B12 status
- Folate intake
- Medical and pregnancy history
- Current medications
- Other supplements already being taken
Can folic acid be harmful?
Folic acid is generally considered safe when taken at an appropriate dose during preconception and pregnancy.
Problems are more likely to occur when several supplements are taken together and the total amount of folic acid or folate is not reviewed.
Excessive folic acid intake may also make vitamin B12 deficiency harder to detect. This is one reason why a complete supplement review can be useful, particularly if you are taking a prenatal vitamin, fertility supplement and additional B-complex product at the same time.
Important: More folate is not automatically better. The form and dose should be appropriate for your individual needs and medical history.
What foods are naturally rich in folate?
Food remains an important source of natural folate. Good dietary sources include:
- Spinach and other leafy green vegetables
- Kale
- Broccoli
- Asparagus
- Avocado
- Lentils
- Chickpeas
- Beans
- Oranges and other citrus fruits
A nutrient-rich diet supports overall preconception health, but food alone may not provide the amount of folate recommended before pregnancy. This is why supplementation is commonly advised.
Does folate improve fertility?
Folate is involved in DNA synthesis, cell division and normal tissue development. Adequate folate intake supports reproductive and pregnancy health, but folate should not be viewed as a fertility treatment on its own.
If you are trying to conceive, other important factors may include:
- Ovulation and menstrual-cycle regularity
- Egg quality and ovarian reserve
- Sperm count, motility and morphology
- PCOS
- Thyroid health
- Insulin resistance and metabolic health
- Nutrition and nutrient deficiencies
- Smoking, alcohol, sleep and exercise
- Underlying reproductive or medical conditions
Folate is one important part of a broader fertility and preconception plan.

When should you start taking folate?
Folate supplementation is generally started before conception, often at least one month before trying to become pregnant, and continued during early pregnancy.
Some women may be advised to begin earlier or take a different dose depending on their medical history, medications, previous pregnancies or risk factors.
If you are preparing for IVF, ICSI or another fertility treatment, discuss your supplement plan with your fertility specialist and healthcare practitioner before treatment begins.
Can you take folic acid and methylfolate together?
Some prenatal and fertility supplements contain more than one form of folate. However, taking separate folic acid and methylfolate products may result in an unnecessarily high total dose.
Check the labels of all supplements you use and look for terms such as:
- Folic acid
- Folate
- 5-MTHF
- Methylfolate
- Calcium folinate
A practitioner can help calculate your total intake and determine whether multiple forms are necessary.
When should you seek personalised advice?
Professional guidance may be particularly helpful if you:
- Are trying to conceive
- Are preparing for IVF or ICSI
- Have experienced recurrent miscarriage
- Have PCOS or irregular ovulation
- Have elevated homocysteine
- Have a known MTHFR variant
- Have low vitamin B12 or iron
- Are taking several fertility supplements
- Have experienced side effects from a prenatal vitamin
- Are unsure which folate dose is appropriate

Final thoughts
Folic acid and methylfolate can both play an important role in preconception and pregnancy care.
For many women, standard folic acid remains an appropriate choice. For others, particularly those with a complex fertility history, recurrent miscarriage, elevated homocysteine or specific medical considerations, a personalised approach may be useful.
The goal is not simply to choose the supplement described online as “best.” The goal is to make sure your folate intake, prenatal supplement, diet and fertility plan are safe and appropriate for your individual needs.
