When it comes to fertility, nutrition plays a vital role in preparing your body for conception. However, with so much conflicting information, exaggerated promises, and supplement promotions targeting fertility, it can be overwhelming to know what truly matters. Evidence-based nutrition is key in supporting reproductive health. This can be achieved by prioritising practical and sustainable strategies that nourish the body—without the need for restrictive diets or expensive interventions.

Key Nutritional Considerations for Fertility

Balanced Diet for Hormone Health

A nourishing diet that includes whole foods, healthy fats, quality proteins, and complex carbohydrates helps regulate hormones, support ovulation, and improve egg and sperm quality. The Mediterranean diet—rich in fruits, vegetables, whole grains, olive oil, and fish—has been consistently associated with improved fertility outcomes.

Managing Blood Sugar and Insulin Levels

For women with conditions such as polycystic ovary syndrome (PCOS), managing insulin and blood sugar is essential. A low glycaemic index diet high in fibre, and balanced with healthy fats and protein, can support more regular ovulation and reduce the effects of insulin resistance on reproductive health.

Healthy Fats for Hormone Production

Omega-3 fatty acids and other essential fats play a key role in hormone synthesis. Including foods like oily fish, linseeds, walnuts, and chia seeds can help maintain healthy hormone levels and support fertility by reducing inflammation and promoting hormonal balance.

Micronutrients for Reproductive Function

Key vitamins and minerals—such as folate, B12, vitamin D, zinc, iron, iodine, and selenium—contribute to reproductive health. They support egg and sperm quality, regulate menstrual cycles, and improve the likelihood of conception and healthy pregnancy outcomes.

Anti-Inflammatory Diet

Low-grade chronic inflammation may negatively affect fertility. Diets high in antioxidants, omega-3s, and unprocessed whole foods can help reduce inflammation and support a healthy reproductive environment.

Gut Health and Fertility

A healthy gut microbiome supports hormone metabolism and modulates inflammation. Including fermented foods like kefir, yogurt, and sauerkraut, as well as fibre from vegetables, legumes, and whole grains, may improve gut function and overall fertility.

Understanding BMI and Fertility

While BMI is often used in fertility assessments, it’s important to recognise that weight-related guidance can feel overwhelming—especially for individuals with PCOS, diabetes/prediabetes, chronic dieting history, or disordered eating. Even modest weight changes (e.g. 5–10%) may improve fertility, but a focus on nourishment, hormone support, and reducing stress around food is often more helpful than pursuing strict weight targets.

Stress and Mental Well-being

High stress levels can impact hormone regulation and reproductive function. Supporting mental wellbeing through regular, balanced meals, gentle movement, and mindfulness practices can reduce the burden of stress and help create a more balanced foundation for conception.

Supplements and Evidence-Based Guidance

There is a lot of information, big promises, and supplement promotion for those trying to conceive. While certain supplements may be helpful in specific cases, there is not a one-size-fits-all solution. It’s important to consult your health team before spending money on fertility supplements.

Summary

Nutrition can play a key role in supporting fertility, but it doesn’t need to be complicated or restrictive. By focusing on balanced meals, quality nutrients, and a peaceful relationship with food, you can create the right conditions for conception.
