There is something quietly heartbreaking about wanting a baby and feeling like your body is not cooperating. Month after month, hope rises and falls, and you begin to wonder whether something you are doing — or not doing — is standing in the way. What many women do not realize is that what is on their plate every single day has a profound influence on their reproductive health, from the quality of their eggs to the regularity of their cycles and the hormones that orchestrate it all.
Fertility is not simply a matter of timing. It is shaped by inflammation, oxidative stress, insulin sensitivity, thyroid function, and nutrient availability — all of which are directly influenced by diet. Conditions such as PCOS, irregular ovulation, poor egg quality, and luteal phase deficiency are frequently rooted in nutritional imbalances that can be addressed before turning to more invasive interventions. Research published in Nutrients and the American Journal of Obstetrics and Gynecology consistently shows that dietary patterns rich in whole foods, antioxidants, and healthy fats are associated with higher conception rates and better IVF outcomes.
In the sections ahead, you will discover the most fertility-supportive foods, the nutrients that matter most for egg quality and hormonal balance, the dietary patterns backed by clinical evidence, and the foods to minimize when trying to conceive. Whether you are just starting your preconception journey or have been trying for a while, this guide gives you an actionable roadmap rooted in science.
Fertility Superfoods: What to Eat More of When Trying to Conceive
The foundation of any fertility diet is nutrient density. Your eggs take approximately 90 days to mature through a process called folliculogenesis, which means the foods you eat today are directly influencing the eggs that will be available for fertilization three months from now. During this window, antioxidants play a particularly critical role by protecting developing follicles from oxidative damage — a key driver of poor egg quality, especially in women over 35.
Leafy greens such as spinach, kale, and Swiss chard are among the most powerful fertility foods available. They are rich in folate, which is essential for DNA synthesis and early neural tube development. Research links adequate folate intake to improved embryo quality and reduced miscarriage risk. Pairing leafy greens with a quality prenatal vitamin — such as Thorne Basic Prenatal with Folate and Choline — can help bridge nutritional gaps, particularly for women who have difficulty absorbing synthetic folic acid.
Fatty fish like salmon and sardines provide omega-3 fatty acids, which reduce reproductive inflammation and support healthy progesterone production. Eggs — particularly the yolk — supply choline, vitamin D, and healthy fat, all of which are critical for hormonal signaling. Berries, particularly blueberries and strawberries, deliver anthocyanins and vitamin C that neutralize free radicals in the reproductive system. Walnuts are exceptional for their plant-based omega-3 and melatonin content, which some research suggests may improve follicle quality.
Full-fat dairy, often overlooked, is associated with better ovulatory function in the landmark Nurses’ Health Study, with women consuming full-fat dairy showing a lower risk of ovulatory infertility compared to those eating low-fat versions. This benefit is attributed to the fat-soluble vitamins and hormonal precursors present in whole dairy that are stripped away during processing. If you are looking to improve egg quality after 35, incorporating these whole-food sources of antioxidants, healthy fats, and folate is one of the most impactful steps you can take.
- Leafy greens (spinach, kale, arugula): rich in folate and iron for cycle regularity and embryo health
- Fatty fish (salmon, sardines, mackerel): provide omega-3s to reduce inflammation and support progesterone
- Eggs and full-fat dairy: supply choline, vitamin D, and ovulatory-supportive saturated fats
- Berries and citrus: antioxidant-rich foods that protect egg DNA from oxidative damage
- Walnuts and Brazil nuts: offer selenium and plant-based omega-3s critical for thyroid and ovarian function
Key Fertility Nutrients: What Your Body Needs to Conceive
Beyond individual foods, specific micronutrients have well-established roles in female reproductive function. Understanding which nutrients are most critical — and where deficiencies are most common — allows you to tailor your diet and supplementation strategy with precision.
Folate (as methylfolate, not synthetic folic acid) is the cornerstone of preconception nutrition. It supports cell division, DNA replication, and early embryonic development. Women with the MTHFR gene variant cannot properly convert folic acid into its active form, making food-based and methylated folate especially important. Closely related, vitamin B12 deficiency has been linked to irregular ovulation and early pregnancy loss — another reason whole prenatal support matters before conception begins.
Iron is frequently overlooked in the fertility conversation. Yet research from the Nurses’ Health Study found that women who supplemented with non-heme iron had a significantly lower risk of ovulatory infertility. Plant-based iron sources such as lentils, pumpkin seeds, and fortified cereals combined with vitamin C support non-heme iron absorption effectively.
Zinc is indispensable for follicle development, ovulation, and progesterone production. Even mild zinc deficiency can disrupt hormonal signaling. Selenium, particularly abundant in Brazil nuts, protects eggs from oxidative stress and is essential for thyroid hormone conversion — a critical factor since thyroid health underpins menstrual regularity and implantation success. You can read more about the role of selenium in thyroid health for conception on our site.
CoQ10 is one of the most researched fertility nutrients, particularly for women over 35. It powers the mitochondria inside egg cells and supports the energy-intensive process of meiosis. Clinical studies show CoQ10 supplementation improves follicle maturation and IVF response rates. Vitamin D acts as a hormone precursor in the ovaries and endometrium — deficiency is strongly associated with longer time to conception and higher miscarriage rates. Ensuring your prenatal supplement includes these nutrients is essential; options like Nature Made Prenatal with Folic Acid and DHA or the more comprehensive Ritual Essential for Women Prenatal Multivitamin can offer a solid nutritional baseline.
- Methylfolate: critical for DNA synthesis, embryo quality, and neural tube protection from conception onward
- Iron (non-heme): supports ovulation; low levels associated with anovulatory cycles
- Zinc and selenium: essential for follicle maturation, progesterone output, and thyroid conversion
- CoQ10 (ubiquinol): mitochondrial support for egg energy production, especially important after 35
- Vitamin D: acts as a reproductive hormone; deficiency linked to implantation failure and cycle irregularity
The Mediterranean Diet and Fertility: What the Research Says
Of all the dietary patterns studied in reproductive medicine, the Mediterranean diet has the strongest and most consistent evidence base for improving fertility outcomes. Characterized by abundant vegetables, legumes, whole grains, nuts, seeds, olive oil, and moderate fish consumption — with limited red meat and processed foods — this dietary pattern addresses nearly every nutritional root cause of impaired fertility in women.
A landmark study published in Human Reproduction found that women who closely adhered to a Mediterranean diet had significantly higher rates of clinical pregnancy and live birth during IVF compared to those with poor adherence. The researchers attributed these benefits to the diet’s combined effect on reducing systemic inflammation, improving insulin sensitivity, and delivering a broad spectrum of antioxidants and micronutrients that support oocyte quality.
The anti-inflammatory properties of the Mediterranean diet are particularly relevant for women with endometriosis or PCOS, two of the most common causes of fertility challenges. Chronic inflammation damages the follicular environment and disrupts the hormonal cascade required for ovulation. Olive oil, a centerpiece of this dietary pattern, is rich in oleocanthal — a compound with anti-inflammatory effects comparable to low-dose ibuprofen — as well as vitamin E, which protects the uterine lining and supports implantation.
Legumes such as lentils, chickpeas, and black beans provide plant-based protein and resistant starch that stabilize blood sugar levels, a key factor in maintaining the hormonal balance needed for regular ovulation. The fiber in these foods also supports healthy estrogen metabolism through the gut microbiome, a mechanism increasingly recognized as central to hormonal regulation. For women with PCOS, where insulin resistance and androgen excess are common drivers, the Mediterranean diet’s emphasis on low-glycemic foods can help regulate cycles and reduce androgen levels without medication. Pairing this dietary approach with targeted hormonal support — such as Wholesome Story Myo Inositol and D-Chiro Inositol for Hormone Balance — may offer additional benefits for those with insulin-related fertility disruption.
Whole grains like quinoa, farro, and oats replace refined carbohydrates that spike blood sugar and trigger inflammatory cascades. The combination of complex carbohydrates, fiber, and B vitamins in whole grains supports steady energy, hormone production, and healthy progesterone levels throughout the luteal phase.
Foods to Limit on the Fertility Diet
Understanding what to remove from your diet is just as important as knowing what to add. Several food categories have been identified in population-level research as negatively associated with fertility, particularly when consumed in high quantities over prolonged periods.
Ultra-processed foods — including packaged snacks, fast food, and refined grain products — are among the most damaging to reproductive health. These foods are typically high in trans fats, refined sugars, and additives that promote systemic inflammation, disrupt insulin signaling, and interfere with the hormonal communication necessary for ovulation. A 2018 study in Human Reproduction found that women who consumed more fast food and less fruit had longer time to pregnancy and higher rates of infertility.
Sugar-sweetened beverages deserve special attention. Regular consumption of sodas and sweetened juices has been linked to irregular menstrual cycles and reduced fertility in women. High-fructose corn syrup, the primary sweetener in many of these drinks, impairs insulin sensitivity and raises uric acid levels — both of which negatively affect ovarian function. Replacing these with filtered water, herbal teas, or infused water is one of the most straightforward dietary improvements a woman trying to conceive can make.
Alcohol consumption, even at moderate levels, has been associated with hormonal disruption and reduced conception rates in multiple prospective studies. Alcohol raises estrogen levels through altered liver metabolism, which can suppress ovulation and impair the luteal phase. While an occasional glass may not be cause for alarm, eliminating alcohol entirely during the preconception period is generally recommended by reproductive endocrinologists.
Excess caffeine — typically defined as more than 200 mg per day — has been associated with longer time to pregnancy and increased miscarriage risk in some studies, though evidence remains mixed. Erring on the side of caution by limiting coffee to one cup daily and avoiding energy drinks is advisable. Reducing dietary exposure to endocrine-disrupting compounds found in canned foods lined with BPA and heavily processed meats is also worth considering, as these compounds mimic estrogen and can interfere with reproductive signaling.

Frequently Asked Questions
How long does it take for dietary changes to improve fertility?
Because eggs take approximately 90 days to fully mature, most fertility nutritionists recommend committing to dietary improvements for at least three months before trying to conceive. Consistency during this window can meaningfully influence egg quality and hormonal balance.
Can the fertility diet help with PCOS-related infertility?
Yes. A low-glycemic, anti-inflammatory diet such as the Mediterranean diet directly addresses insulin resistance and androgen excess — the primary drivers of PCOS-related ovulatory dysfunction. Research supports dietary intervention as a first-line strategy for improving cycle regularity and conception rates in women with PCOS.
Should I take a prenatal vitamin even before I am pregnant?
Absolutely. Reproductive specialists recommend beginning prenatal vitamins at least three months before trying to conceive. Early folate and choline status are critical for neural tube development in the first weeks of pregnancy, often before a woman even knows she is pregnant.
Does body weight affect fertility and how can diet help?
Both underweight and overweight status can disrupt hormonal balance and ovulation. A nutrient-dense, whole-food diet helps support a healthy weight range, which is associated with better ovulatory function and higher conception rates without the need for extreme caloric restriction.
Are plant-based diets compatible with the fertility diet?
Plant-based diets can be highly fertility-supportive when well-planned. Key considerations include ensuring adequate iron, zinc, B12, omega-3 (via algae-based DHA), and complete protein intake. Supplementation and food combining strategies can address common gaps in plant-based eating for conception.
