When my husband and I decided to start our family, I remember staring at my plate wondering if what I was eating could actually make a difference. As it turns out, nutrition plays a significant role in fertility for both women and men. Research from the Nurses’ Health Study found that women who followed five or more fertility-friendly dietary recommendations had a 66% lower risk of ovulatory infertility compared to those who did not.
What you eat in the months leading up to conception creates the foundation for healthy egg development, sperm quality, and the uterine environment where implantation occurs. While no diet can guarantee pregnancy, evidence shows that specific nutrients and eating patterns can meaningfully improve your chances. I have compiled this guide based on peer-reviewed research, registered dietitian recommendations, and real experiences from couples who have walked this path.
If you are looking for broader lifestyle factors beyond nutrition, our article on evidence-based fertility strategies covers supplements, exercise, and stress management in detail.

Why Nutrition Matters for Fertility in 2026?
The connection between diet and fertility operates on multiple levels. For women, nutrients influence hormone production, egg quality, ovulation regularity, and the quality of cervical mucus that helps sperm reach the egg. For men, dietary factors affect sperm count, motility, and DNA integrity. Studies indicate that sperm take approximately 74 days to develop, which means the choices your partner makes today will impact sperm quality in about two and a half months.
A landmark study published in Fertility and Sterility demonstrated that adherence to a Mediterranean-style diet pattern was associated with improved fertility outcomes in couples undergoing in vitro fertilization. The key elements of this pattern include abundant plant foods, healthy fats like olive oil, moderate fish consumption, and limited processed foods.
The preconception period, typically defined as the three months before conception, represents a critical window. This timeframe allows egg follicles to mature with optimal nutrient support and gives sperm time to develop in a nourishing environment. Starting dietary improvements at least 90 days before trying to conceive maximizes the potential benefits.
Key Nutrients for Conception
Before diving into specific foods, understanding the key nutrients that support fertility will help you make informed choices. These building blocks work synergistically to create the best possible conditions for conception.
Folate and Folic Acid
Folate tops every fertility nutrition list for good reason. This B vitamin is essential for DNA synthesis, cell division, and preventing neural tube defects in early pregnancy. The Centers for Disease Control and Prevention recommends that women consume 400 to 800 micrograms of folic acid daily, starting at least one month before conception. Food sources include dark leafy greens, fortified cereals, legumes, and citrus fruits.
Iron
Iron deficiency and anemia are surprisingly common among women of childbearing age and can negatively impact fertility. A study from Harvard found that women who consumed iron supplements had a significantly lower risk of ovulatory infertility compared to those who did not. Iron-rich foods include lean red meat, spinach, lentils, and fortified cereals. Pairing plant-based iron sources with vitamin C-rich foods enhances absorption.
Omega-3 Fatty Acids
These essential fats, particularly DHA and EPA found in fatty fish, support hormone production, improve blood flow to reproductive organs, and help regulate inflammation. Research suggests that adequate omega-3 intake may improve egg quality and promote healthy implantation. If you do not consume fish, algae-based omega-3 supplements provide a plant-based alternative.
Antioxidants
Antioxidants like vitamins C and E, selenium, and glutathione protect eggs and sperm from oxidative stress and free radical damage. This protection is particularly important for egg quality in women over 35 and for maintaining healthy sperm DNA. Colorful fruits and vegetables provide a wide spectrum of these protective compounds.
Zinc and Selenium
These trace minerals are critical for both male and female fertility. Zinc supports hormone regulation and cell division, while selenium acts as an antioxidant and supports thyroid function. Together they play essential roles in sperm formation and embryo development. Good sources include oysters, Brazil nuts, pumpkin seeds, and whole grains.
Vitamin D
Vitamin D deficiency has been linked to infertility and poor IVF outcomes. This hormone-vitamin affects both egg quality and implantation. Many adults are deficient, particularly those with limited sun exposure. Testing levels and supplementing if necessary is a smart preconception step. Food sources include fatty fish, egg yolks, and fortified dairy products.
Choline
Choline is increasingly recognized for its importance in early fetal brain development, but it also supports fertility. Most prenatal vitamins contain little to no choline, making food sources essential. Eggs are the richest source, with one large egg providing about 147 milligrams. Other sources include liver, salmon, and Brussels sprouts.
Best Foods to Boost Fertility (2026)
Now that we have covered the key nutrients, let us look at the specific foods that deliver these fertility-supporting compounds. I have organized these by food category to make meal planning easier.
Dark Leafy Greens
Spinach, kale, Swiss chard, and arugula pack impressive amounts of folate, iron, and calcium. Just one cup of cooked spinach provides over 250 micrograms of folate, more than half the daily recommendation. These vegetables also contain antioxidants that support overall reproductive health.
Practical tip: Add a handful of baby spinach to smoothies, or saute kale with garlic as a simple side dish. Frozen spinach works just as well as fresh and is often more affordable.
Fatty Fish
Salmon, sardines, mackerel, and herring deliver omega-3 fatty acids along with vitamin D and protein. Aim for two to three servings per week of low-mercury options. Wild-caught salmon often contains higher omega-3 levels than farmed varieties, though both provide benefits.
Budget-friendly alternative: Canned salmon and sardines offer the same nutrients at a fraction of the cost. A can of sardines costs around two dollars and provides over one gram of omega-3s.
Colorful Berries
Blueberries, strawberries, raspberries, and blackberries are antioxidant powerhouses. Their high vitamin C content also helps your body absorb iron from plant sources. Studies suggest that antioxidants may improve egg quality, particularly in women over 35.
Fresh berries can be expensive, but frozen berries offer the same nutritional benefits and work beautifully in smoothies, oatmeal, or yogurt parfaits.
Whole Grains
Quinoa, brown rice, oats, and whole wheat provide B vitamins, fiber, and complex carbohydrates that help regulate blood sugar. Maintaining steady blood sugar supports hormonal balance and reduces inflammation. Research from the Nurses’ Health Study found that women who ate more whole grains had lower rates of ovulatory infertility.
Start your day with oatmeal topped with nuts and berries, or substitute quinoa for white rice at dinner. These simple swaps make a meaningful difference over time.
Legumes
Lentils, chickpeas, and black beans offer plant-based protein, iron, folate, and fiber. They have a low glycemic index, meaning they do not spike blood sugar levels. This makes them particularly beneficial for women with PCOS or insulin resistance. A cup of cooked lentils provides 18 grams of protein and nearly 360 micrograms of folate.
Legumes are also incredibly budget-friendly. A pound of dried lentils costs about two dollars and yields multiple servings.
Nuts and Seeds
Walnuts deserve special mention for fertility. UCLA Health research found that walnuts contain omega-3s, polyamines, and spermidine that support ovulation and sperm health. A daily handful of walnuts is an easy fertility boost. Other excellent options include almonds, pumpkin seeds, and ground flaxseeds.
Seeds also play a role in fertility nutrition. Flaxseeds provide lignans that may help regulate estrogen levels, while pumpkin seeds offer zinc. If you are curious about the popular trend of using seeds for fertility, our article on seed cycling for fertility examines the evidence.
Full-Fat Dairy
The Nurses’ Health Study found that women who consumed one or more servings of full-fat dairy daily had a 27% lower risk of ovulatory infertility compared to those eating low-fat dairy. The fat-soluble vitamins in whole milk, yogurt, and cheese appear to support reproductive hormone function.
Choose plain full-fat yogurt over sugary varieties, and opt for whole milk if you enjoy dairy. If you are lactose intolerant, fermented options like kefir may be easier to tolerate.
Citrus Fruits
Oranges, grapefruits, lemons, and limes provide vitamin C and folate. Grapefruit juice has gained attention in fertility circles for potentially improving cervical mucus quality, though evidence is limited. What we do know is that vitamin C enhances iron absorption and provides antioxidant protection.
Avocados
This creamy fruit delivers monounsaturated fats that support hormone production, along with folate, vitamin E, and potassium. Vitamin E is particularly important for protecting sperm membranes from oxidative damage. Adding avocado to salads, smoothies, or toast is an easy way to boost nutrition.
Sweet Potatoes
Rich in beta-carotene, sweet potatoes may help promote healthy cervical mucus production. They also provide complex carbohydrates and fiber that support steady blood sugar. Swap regular potatoes for sweet potatoes, or try roasted sweet potato cubes as a side dish.
Eggs
Eggs are one of the most nutrient-dense foods available, providing choline, protein, vitamin D, and omega-3s if you choose omega-3 enriched varieties. Despite past concerns about cholesterol, current research supports eggs as part of a healthy diet for most people.
Foods to Limit or Avoid When Trying to Conceive
Just as certain foods support fertility, others can hinder it. Here is what to minimize or eliminate during your preconception period.
Trans Fats and Processed Foods
Trans fats not only raise bad cholesterol but also increase the risk of ovulatory infertility. The Nurses’ Health Study found that each 2% increase in trans fat calories consumed was associated with a 73% greater risk of ovulatory infertility. Trans fats hide in fried foods, baked goods, margarine, and anything with partially hydrogenated oils in the ingredient list.
Processed foods often contain refined carbohydrates, unhealthy fats, and additives that promote inflammation. Building meals around whole foods reduces exposure to these fertility-disrupting ingredients.
Excessive Caffeine
The American College of Obstetricians and Gynecologists recommends limiting caffeine to under 200 milligrams per day when trying to conceive and during pregnancy. This equals about one 12-ounce cup of coffee. Higher caffeine intake has been linked to delayed conception and increased miscarriage risk in some studies.
If you are a heavy coffee drinker, consider gradually reducing intake to avoid withdrawal headaches. Green tea offers a lower-caffeine alternative with antioxidant benefits.
Alcohol
Alcohol affects fertility in both men and women. For women, it can disrupt menstrual cycles and hormone levels. For men, it reduces testosterone and sperm quality. The CDC and ACOG recommend abstaining from alcohol when trying to conceive to eliminate any risk to a developing embryo.
High-Mercury Fish
While fish is beneficial for fertility, certain species contain high levels of mercury that can harm a developing nervous system. Avoid shark, swordfish, king mackerel, tilefish, and bigeye tuna. Opt for low-mercury choices like salmon, sardines, trout, and light canned tuna instead.
Processed Soy and Phytoestrogens
Soy contains phytoestrogens that may interfere with hormone function in high amounts. While moderate consumption of whole soy foods like tofu and edamame is likely fine, processed soy ingredients in packaged foods and soy supplements are best minimized during the preconception period.
Sugary Drinks and Refined Carbohydrates
Sugary beverages and refined carbohydrates spike blood sugar and insulin levels, which can disrupt ovulation. Women with PCOS are particularly sensitive to these effects. Replace soda and juice with water, and choose whole grains over white bread and pasta.
Unpasteurized Foods
Unpasteurized dairy, soft cheeses, and raw or undercooked animal products carry risks of foodborne illness. While trying to conceive, it is wise to avoid these foods to protect your health and reduce any potential risks to an early pregnancy.
Fertility Nutrition for Men
Fertility is not just a woman’s concern. Male factor infertility contributes to approximately 40% of infertility cases, and nutrition significantly impacts sperm health. Since sperm development takes about 74 days, the dietary changes your partner makes today will show up in sperm quality in roughly two and a half months.
Key Nutrients for Male Fertility
Men need many of the same nutrients as women for optimal fertility, with some specific emphases. Zinc is crucial for testosterone production and sperm formation. Selenium supports sperm motility. Vitamin E protects sperm cell membranes from oxidative damage. Lycopene, found in tomatoes, may improve sperm morphology.
Best Fertility Foods for Men
Oysters contain more zinc per serving than any other food. Just six oysters provide over 500% of the daily recommended intake. Zinc deficiency is linked to low testosterone and poor sperm quality.
Tomatoes and tomato products are rich in lycopene, an antioxidant that gives them their red color. Studies suggest lycopene may improve sperm count and viability. Cooked tomatoes, like in sauce or soup, provide more bioavailable lycopene than raw.
Walnuts provide omega-3 fatty acids and arginine, an amino acid that may improve blood flow. Research from UCLA found that men who ate 75 grams of walnuts daily experienced improved sperm vitality, motility, and morphology.
Berries offer antioxidants that protect sperm from oxidative stress. Blueberries, strawberries, and raspberries are all excellent choices.
Dark leafy greens provide folate, which is essential for healthy sperm DNA. Studies link adequate folate intake to lower rates of sperm chromosomal abnormalities.
Foods Men Should Avoid
Men should follow the same general guidelines as women regarding trans fats, excessive alcohol, and processed foods. Additionally, soy-heavy diets and anabolic steroid use significantly impair sperm production. Keeping cell phones away from the groin area and avoiding excessive heat in hot tubs or saunas also supports healthy sperm production.
Sample Fertility Meal Plan
Putting all this information into practice can feel overwhelming. Here is a sample day of eating that incorporates fertility-friendly foods at every meal. I have included budget-friendly swaps and vegetarian alternatives.
Breakfast Ideas
Fertility Smoothie: Blend 1 cup frozen berries, 1 tablespoon ground flaxseed, 1 handful spinach, 1/2 avocado, 1 cup Greek yogurt, and almond milk. This delivers antioxidants, omega-3s, folate, and protein.
Steel-Cut Oatmeal: Cook oats in milk, then top with walnuts, sliced banana, and a drizzle of honey. Add a side of eggs for extra protein and choline.
Lunch Ideas
Mediterranean Quinoa Bowl: Combine cooked quinoa with chickpeas, cucumber, tomatoes, olives, feta cheese, and olive oil dressing. Serve with a side of orange slices.
Salmon Salad: Mix canned salmon with avocado, lemon juice, and herbs. Serve over dark leafy greens with whole grain crackers.
Dinner Ideas
Baked Salmon with Sweet Potato: Roast a salmon fillet with lemon and herbs alongside cubed sweet potatoes and steamed broccoli.
Lentil Curry: Simmer red lentils in coconut milk with turmeric, spinach, and tomatoes. Serve over brown rice with a dollop of full-fat yogurt.
Snack Ideas
A handful of walnuts and almonds, full-fat yogurt with berries, hard-boiled eggs, carrots with hummus, or an apple with almond butter all make fertility-supporting snacks.
Budget-Friendly Fertility Eating
Eating for fertility does not require expensive superfoods. Frozen vegetables are often more nutritious than fresh ones that have traveled long distances. Canned salmon and sardines deliver the same omega-3s as fresh fish at a lower cost. Dried beans and lentils are incredibly affordable protein sources. Buying nuts and seeds in bulk reduces cost significantly.
Focus on these budget-friendly fertility foods: eggs, frozen spinach, canned salmon, dried lentils, brown rice, oats, seasonal fruits, and bulk nuts.
Vegetarian and Vegan Adaptations
Plant-based eaters can absolutely follow a fertility-supporting diet with some planning. Emphasize legumes, nuts, seeds, and whole grains for protein and zinc. Include algae-based omega-3 supplements since plant sources like flax provide only ALA, which converts inefficiently to EPA and DHA. Consider B12, iron, and vitamin D supplementation after consulting with your healthcare provider.
For women with PCOS, a lower glycemic index approach may be particularly beneficial. Our article on PCOS-specific fertility guidance offers tailored dietary advice.
Supplements and Lifestyle Factors
Prenatal Vitamins
Most healthcare providers recommend starting a prenatal vitamin at least three months before conception. Look for one containing at least 400 micrograms of folic acid, iron, iodine, and vitamin D. Some also contain DHA, though you may need a separate omega-3 supplement for adequate intake.
Remember that supplements complement, not replace, a healthy diet. The fiber, phytonutrients, and food matrix of whole foods provide benefits that isolated nutrients cannot replicate.
Weight and Fertility
Body weight significantly impacts fertility for both women and men. Women with a BMI below 18.5 or above 30 may experience ovulatory irregularities. Men with obesity often have lower sperm counts. The good news is that modest weight changes, even 5 to 10 percent of body weight, can significantly improve fertility outcomes.
For more detailed information on this topic, read our article on how weight impacts fertility.
Hydration
Adequate hydration supports cervical mucus production and overall reproductive health. Aim for at least eight glasses of water daily. Herbal teas like raspberry leaf and nettle have traditional use for fertility, though scientific evidence is limited. Avoid excessive green tea consumption due to caffeine content.
Exercise
Moderate exercise supports fertility by maintaining healthy weight and reducing stress. However, excessive high-intensity exercise can disrupt menstrual cycles in some women. Aim for 150 minutes of moderate activity weekly, such as brisk walking, swimming, or yoga.
Stress and Sleep
Chronic stress and poor sleep disrupt hormonal balance. Prioritize seven to nine hours of quality sleep nightly. Stress management techniques like meditation, deep breathing, or gentle yoga can support both fertility and overall wellbeing.
Frequently Asked Questions
What not to eat while trying to conceive?
Avoid trans fats found in fried and processed foods, limit caffeine to under 200mg daily, abstain from alcohol, skip high-mercury fish like shark and swordfish, minimize processed soy, and reduce sugary drinks and refined carbohydrates. Unpasteurized dairy and raw animal products also carry food safety risks.
What can I drink to conceive faster?
Water is the best beverage for fertility. Herbal teas like raspberry leaf are traditionally used. Whole milk and full-fat dairy may support ovulatory health. Limit caffeine to under 200mg daily. Avoid alcohol and sugary drinks. Some women drink grapefruit juice hoping to improve cervical mucus, though evidence is limited.
What are 5 foods that improve egg quality?
1. Walnuts provide omega-3s and antioxidants that protect eggs. 2. Berries deliver vitamin C and polyphenols that reduce oxidative stress. 3. Leafy greens like spinach offer folate for DNA synthesis. 4. Fatty fish provide omega-3 fatty acids for cell membrane health. 5. Eggs contain choline and vitamin D that support egg development.
At what age are 90% of your eggs gone?
By age 30, women have lost about 90% of the eggs they were born with. At birth, females have approximately 1 to 2 million eggs. By puberty, this number drops to around 300,000. The decline accelerates after age 35, though women can still conceive naturally into their 40s. Diet and lifestyle can help optimize the remaining eggs.
How long before conception should I change my diet?
Start making dietary changes at least three months before trying to conceive. Eggs take approximately three months to mature from follicle to ovulation. Sperm development takes about 74 days. This timeline ensures that your improved nutrition supports the development of healthy eggs and sperm.
Can diet alone fix infertility?
Diet cannot cure all forms of infertility. Structural issues, blocked fallopian tubes, severe endometriosis, and genetic factors require medical intervention. However, diet can significantly improve ovulatory function, egg quality, and sperm health. The Nurses’ Health Study found that women following fertility-friendly diets had 66% lower risk of ovulatory infertility.
Is the fertility diet expensive?
Fertility nutrition does not require expensive superfoods. Budget-friendly options include eggs, frozen spinach, canned salmon and sardines, dried beans and lentils, brown rice, oats, seasonal fruits, and bulk nuts. Focus on whole foods rather than processed products, which often costs less than convenience foods.
Conclusion
What you eat when trying to conceive creates the nutritional foundation for healthy conception and pregnancy. By emphasizing whole foods, healthy fats, lean proteins, and abundant fruits and vegetables while minimizing processed foods and harmful substances, you give yourself the best possible chance of success. Remember that small changes add up over time, and the three-month preconception window gives you space to gradually transition to fertility-friendly eating patterns.
Both partners benefit from these dietary improvements. Male fertility nutrition is equally important, and making these changes together creates a supportive environment for your fertility journey.
If you have been trying to conceive for 12 months without success if you are under 35, or six months if you are over 35, consult with a fertility specialist. For couples with known fertility issues, seek guidance sooner. Diet is one powerful tool in your fertility toolkit, but it works best alongside appropriate medical care.
