What to Eat Before Trying to Conceive
Deciding what to eat before trying to conceive is one of the most common first steps couples take once they start planning a pregnancy, and for good reason: nutrition status before conception can influence everything from neural tube development to how the early weeks of pregnancy unfold. The good news is that a preconception diet doesn't need to be complicated or restrictive. It mostly means building on the basics of a balanced diet and closing a few specific nutrient gaps ahead of time.
What to Eat Before Trying to Conceive
Before trying to conceive, prioritize a balanced diet with plenty of vegetables, fruit, whole grains, lean protein, and healthy fats, along with a daily prenatal vitamin containing folic acid. Iron, calcium, and omega-3s also matter. No single food guarantees pregnancy, but steady, varied nutrition supports the body's preparation for it.
What Nutrients Matter Most in a Preconception Diet?
A preconception diet for women centers on a handful of nutrients that research consistently links to healthy early pregnancy outcomes. Folic acid is the standout: the CDC recommends 400 micrograms daily for anyone who could become pregnant, starting at least a month before conception, because the neural tube forms in the first weeks after conception, often before a pregnancy is confirmed.
Beyond folic acid, iron supports the increased blood volume pregnancy requires, calcium supports bone health for both parent and baby, and iodine supports thyroid function, which in turn supports fetal brain development. Omega-3 fatty acids, particularly DHA, are also commonly recommended in the months before conception.
Which Foods Should You Eat When Trying to Get Pregnant?
There's no single fertility superfood, but certain food groups reliably supply the nutrients above. A useful way to think about it is by nutrient and food source rather than by chasing any one "fertility diet."
| Nutrient | Why it matters | Food sources |
|---|---|---|
| Folate/folic acid | Supports neural tube development in early pregnancy | Leafy greens, lentils, fortified cereal, citrus |
| Iron | Supports increased blood volume and oxygen delivery | Lean red meat, beans, spinach, fortified grains |
| Calcium | Supports bone health for parent and baby | Dairy, fortified plant milk, tofu, leafy greens |
| Iodine | Supports thyroid and fetal brain development | Dairy, eggs, iodized salt, seafood |
| Omega-3 (DHA) | Supports fetal brain and eye development | Low-mercury fish, walnuts, flaxseed, algae oil |
Whole, minimally processed foods across these groups generally beat any single "superfood" for building a solid nutritional baseline before conception.
Do You Need to Take Folic Acid Before Pregnancy?
Yes. Folic acid before pregnancy is one of the few preconception recommendations with strong, consistent backing from major health authorities, including the CDC and ACOG. Because neural tube defects can develop within the first month after conception, waiting until a positive pregnancy test to start supplementing is often too late to get the full benefit. Anyone who could become pregnant and isn't actively avoiding it is generally advised to take a supplement with at least 400 mcg of folic acid daily, though people with certain risk factors may be advised to take more under a doctor's guidance.
What Should You Avoid When Trying to Conceive?
Alongside adding nutrients, a few things are worth limiting or avoiding:
- Alcohol, since no amount has been established as clearly safe once trying to conceive
- High-mercury fish, such as swordfish and king mackerel
- Unpasteurized dairy and juice, which carry a higher risk of foodborne illness
- Excess caffeine, generally kept under about 200 mg per day per most clinical guidance
- Crash diets or very restrictive eating patterns, which can disrupt ovulation
None of these need to be treated as high-stakes rules to panic over. They're general guardrails, and an occasional exception is unlikely to matter much against a generally balanced diet.
Is There a "Best" Diet Before Conceiving?
Despite what best diet before conceiving searches often suggest, there isn't one single eating pattern proven superior for fertility. Diets that consistently show up favorably in research, including Mediterranean-style patterns rich in vegetables, whole grains, fish, and healthy fats, tend to succeed because they're balanced and sustainable, not because of any one ingredient. The same logic applies to a fertility diet for women generally: consistency across weeks and months matters more than any individual meal.
Partners are part of this picture too. Nutrition choices that support male fertility and sperm health follow a similar pattern of whole foods and key micronutrients, so preconception nutrition is often worth approaching as a household habit rather than one partner's task alone.
The Bottom Line
What to eat before trying to conceive doesn't require an elaborate overhaul. A balanced diet built around vegetables, whole grains, lean protein, and healthy fats, plus a daily prenatal vitamin with folic acid, covers most of what current guidance recommends. Once conception happens, nutrition priorities shift again, so it's worth reviewing what to avoid during early pregnancy as the next step. And if you're tracking cycles to time conception, ovulation tracking apps can complement good nutrition habits, though neither replaces guidance from your own healthcare provider.
