When you're trying to conceive, you want to do everything in your power to support your body. And while no single food is going to guarantee pregnancy, what you eat plays a genuine and meaningful role in your fertility. The nutrients in your diet affect egg quality, hormonal balance, ovulation regularity, and the uterine environment that a fertilized egg needs to implant and thrive.
The research on fertility nutrition has grown significantly in recent years. The "fertility diet" — a concept supported by the landmark Nurses' Health Study from Harvard — emphasizes whole foods, healthy fats, plant-based proteins, and complex carbohydrates. Here are 15 specific foods that deserve a regular spot on your plate when you're TTC.
Your eggs take approximately 90 days to mature before ovulation. That means the nutritional environment of the past three months affects the quality of the egg you ovulate today. Nutrients like folate, antioxidants, zinc, and omega-3 fatty acids protect eggs from oxidative damage, support healthy DNA replication, and help regulate the hormones that govern your cycle.
Diet also directly impacts insulin sensitivity — which is closely tied to ovulatory function. Diets high in refined carbohydrates and sugars promote insulin resistance, which disrupts LH and FSH signaling and can suppress ovulation. A fertility-focused diet helps keep blood sugar stable and hormones in balance.
Spinach, kale, Swiss chard, and romaine lettuce are rich in folate — one of the most critical nutrients in early pregnancy. Adequate folate before and during early pregnancy dramatically reduces the risk of neural tube defects. Beyond folate, leafy greens provide iron, magnesium, and antioxidants that support overall reproductive health. Aim for at least two large servings daily.
Salmon is one of the richest sources of omega-3 fatty acids (DHA and EPA), which play a crucial role in egg development and embryo implantation. Omega-3s also have anti-inflammatory properties that support a healthy uterine lining. Choose wild-caught over farmed for higher omega-3 content and lower contamination risk. Two to three servings per week is ideal.
Eggs — particularly the yolk — are packed with choline, a nutrient that's critical for brain development and often overlooked in prenatal nutrition. They also provide vitamin D, B12, and high-quality protein. Don't skip the yolk; that's where the fertility-supporting nutrients are concentrated. One to two eggs daily is a great habit to build while TTC.
Avocados are loaded with healthy monounsaturated fats, which are essential for absorbing fat-soluble fertility vitamins like vitamins A, D, E, and K. They're also a good source of folate, vitamin K, and potassium. The healthy fats in avocado support hormone production — since many reproductive hormones are made from cholesterol and fat. Add avocado to salads, smoothies, or toast daily.
Berries are antioxidant powerhouses. They contain vitamin C, flavonoids, and anthocyanins that protect eggs and sperm from oxidative stress — which is one of the main causes of poor egg quality and cellular DNA damage. Blueberries in particular have been shown to reduce inflammation, which supports implantation. A daily handful of mixed berries is an easy, delicious fertility habit.
🥗 Pro tip: Antioxidants in food are more bioavailable than those in supplements. Eating a colorful variety of fruits and vegetables gives you the broadest antioxidant protection.
The Nurses' Health Study found that replacing animal protein with plant protein was associated with a significantly lower risk of ovulatory infertility. Lentils and beans are excellent plant protein sources that also provide folate, iron, and fiber. Iron from plant sources (non-heme iron) — particularly when combined with vitamin C — is linked to better ovulatory function. Try to include lentils, chickpeas, or black beans in meals several times per week.
This one surprises many people. The Nurses' Health Study found that women who consumed more full-fat dairy had a lower risk of ovulatory infertility, while low-fat dairy was associated with higher risk. The theory is that removing the fat from dairy also removes fat-soluble hormones like estrogen that may support ovulation. Full-fat yogurt, whole milk, and cheese are good options — in moderate amounts.
Just one or two Brazil nuts per day provides your entire recommended daily intake of selenium — an antioxidant mineral essential for healthy egg development and DNA integrity. Selenium deficiency has been linked to poor egg quality and increased risk of miscarriage. It's one of the most targeted, specific fertility nutrients, and Brazil nuts deliver it in the most bioavailable form.
Walnuts are the nut with the highest omega-3 content — making them a plant-based alternative to fish for boosting anti-inflammatory fatty acids. They also contain melatonin, which has been shown to protect egg cells from oxidative damage during ovulation. A small handful of walnuts daily is a simple, evidence-backed fertility snack.
Quinoa is a complete protein — meaning it contains all nine essential amino acids — and a complex carbohydrate with a low glycemic index. It's also rich in zinc, folate, and iron. Low-GI carbohydrates help keep blood sugar and insulin levels stable, which directly supports regular ovulation. Quinoa makes an excellent base for fertility-friendly grain bowls.
Sweet potatoes are rich in beta-carotene, which the body converts to vitamin A — essential for the development of healthy eggs and embryos. They also contain vitamin B6, which supports progesterone production (critical for a healthy luteal phase and early pregnancy). Their moderate glycemic index makes them a better carbohydrate choice than white potatoes for women with insulin resistance or PCOS.
Sunflower seeds are an outstanding source of vitamin E, a powerful antioxidant that protects egg cells from oxidative damage and supports endometrial lining development. Studies have shown that adequate vitamin E intake is linked to improved implantation rates. They're also high in folate and selenium, making them a compact fertility superfood.
Pomegranate has been used in traditional medicine for fertility for centuries — and modern research is beginning to support this reputation. It's rich in antioxidants including punicalagins and anthocyanins, and some studies suggest it may improve uterine blood flow and endometrial lining thickness, both of which are important for successful implantation. Pomegranate juice or fresh seeds are both excellent options.
Full-fat Greek yogurt is an excellent source of calcium, probiotics, protein, and — if it's vitamin D fortified — a critical fertility vitamin. Vitamin D deficiency is surprisingly common and has been linked to lower rates of successful IVF and natural conception. Gut health also plays an emerging role in hormonal regulation, and the probiotics in yogurt support a healthy microbiome.
Good news for chocolate lovers: dark chocolate with at least 70% cocoa is a legitimate fertility food. It's rich in iron, magnesium, zinc, and antioxidant flavonoids. Iron supports healthy blood and oxygen delivery to the uterus; magnesium supports over 300 enzymatic processes in the body including hormone synthesis. Keep portions moderate — one or two small squares daily is the sweet spot.
Just as important as what you eat is what you reduce:
Even with a great diet, certain nutrients can be hard to get in sufficient amounts from food alone. Key supplements for women TTC include:
