Why nutrition matters before you conceive
Caring for your body starts well before a positive test. The months leading up to conception are an ideal time to build habits that support a healthy pregnancy from the very beginning.
Good preconception nutrition supports egg development, hormone production, and the earliest stages of fetal development — much of which happens before you know you're pregnant. Whether you hope to conceive in weeks or in a year, today's choices lay a lasting foundation.
Folic acid (Vitamin B9)
Supports early development of baby's brain and spinal cord and reduces the risk of certain neural tube defects.
Recommended: 400–800 mcg daily before conception, unless your provider advises otherwise.
Food sources: spinach, kale, broccoli, lentils, black beans, asparagus, oranges, fortified cereals.
Because food alone can fall short, many providers recommend a prenatal vitamin containing folic acid before pregnancy.
Iron
Supports healthy red blood cells and oxygen delivery. Strong iron stores before pregnancy help meet its increased demands.
Sources: lean beef, chicken, turkey, lentils, chickpeas, spinach, pumpkin seeds, fortified cereals.
Tip: pair iron-rich foods with vitamin C (oranges, strawberries, bell peppers, tomatoes) to boost absorption.
Calcium
Builds strong bones and teeth and supports muscle and nerve function.
Sources: milk, yogurt, cheese, fortified plant milk, calcium-set tofu, kale, bok choy, sardines with bones.
Vitamin D
Helps absorb calcium and supports bone health and immunity.
Sources: fatty fish (salmon), egg yolks, fortified milk and plant beverages, fortified cereals.
Some people need a supplement if levels are low. Ask your provider about testing.
Omega-3 fatty acids
DHA supports brain and eye development in pregnancy and your own heart health.
Sources: salmon, sardines, trout, chia seeds, flaxseeds, walnuts.
If you don't eat fish, ask about an algae-based DHA supplement.
Protein
Builds and repairs tissues and supports hormone production. Include a protein source at every meal.
Choices: eggs, chicken, turkey, fish, beans, lentils, Greek yogurt, cottage cheese, tofu, tempeh, nuts and seeds.
Fiber
Supports digestion and helps reduce constipation.
Sources: oats, brown rice, quinoa, whole-grain bread, fruits, vegetables, beans, lentils, chia seeds.
Drink plenty of water as you increase fiber.
Build a balanced plate
Half the plate: fruits and vegetables.
One quarter: lean protein.
One quarter: whole grains or starchy vegetables.
Add healthy fats: avocado, olive oil, nuts, seeds.
Hydration
Water fuels nearly every body function. Sip throughout the day and carry a reusable bottle.
Increase fluids during exercise or hot weather. If plain water is hard, add lemon, cucumber, berries, or mint.
Foods to limit before pregnancy
Highly processed foods and foods high in added sugars.
Sugary beverages and excess sodium.
Excessive caffeine — follow your provider's guidance.
Alcohol, especially when actively trying to conceive.
Healthy weight and lifestyle
Being underweight or overweight can affect fertility for some. Focus on balanced meals, regular activity, sleep, and stress management — not restrictive diets.
Movement: aim for ~150 minutes of moderate activity weekly (walking, swimming, cycling, strength, yoga) unless advised otherwise.
Sleep: 7–9 hours nightly supports hormone regulation.
Stress: meditation, deep breathing, journaling, gentle stretching, time outdoors, and connection with supportive people.
Should you take a prenatal vitamin?
Many providers recommend starting one before pregnancy. Look for folic acid, iron, vitamin D, iodine, and B12 (especially on a vegetarian or vegan diet).
Your provider can help you choose the right prenatal for your needs.
Sample one-day preconception meal plan
Breakfast: veggie omelet, whole-grain toast, fresh berries, glass of milk or fortified plant milk.
Morning snack: Greek yogurt with blueberries and chopped walnuts.
Lunch: grilled chicken salad with mixed greens, quinoa, tomatoes, cucumber, olive oil vinaigrette.
Afternoon snack: apple slices with peanut or almond butter.
Dinner: baked salmon, brown rice, roasted broccoli, side salad.
Evening snack: cottage cheese with fresh fruit.

Perfection isn't the goal — small, consistent improvements make a meaningful difference over time.
