When couples think about preparing for pregnancy, vitamins often get the attention while fats are overlooked. Yet not all fats are equal — and omega-3 fatty acids are among the most talked-about nutrients in reproductive wellness. Here's a clear, practical look at what they are and why they may deserve a place on your plate while trying to conceive.
What are omega-3 fatty acids?
Omega-3s are a family of essential fats, meaning your body can't make them in meaningful amounts and must get them from food. The three you'll hear about most are EPA and DHA — found mainly in oily fish — and ALA, found in certain plants like flaxseed and walnuts. They're considered building blocks for healthy cell membranes throughout the body and are widely recognised as part of a balanced, nutrient-rich diet.
Omega-3s and female reproductive wellness
For women, omega-3s are often discussed in the context of overall hormonal and cellular health. They contribute to a balanced anti-inflammatory diet, and DHA in particular is well known for its role in supporting healthy development during and after pregnancy. While no single nutrient determines fertility, getting enough healthy fats is part of building a strong nutritional foundation before conception — which is why many prenatal and preconception routines emphasise them.
Omega-3s and male fertility
Fertility is a two-person journey, and omega-3s are relevant for men too. Sperm cell membranes are naturally rich in DHA, and researchers have explored connections between dietary omega-3 intake and various measures of sperm health. None of this is a guarantee of results, but it's another reason for partners to share good nutrition habits rather than leaving them to one person alone.
Food sources and signs you may be low
- Oily fish such as salmon, sardines, mackerel and trout (the richest sources of EPA and DHA)
- Plant sources of ALA: flaxseed and flax oil, chia seeds, walnuts and soybeans
- Some fortified eggs, dairy and plant milks
People who rarely eat fish, follow a strict plant-based diet, or eat a lot of processed food may take in fewer omega-3s. There's no simple at-home test, so the practical approach is to focus on regularly including the foods above. If you're unsure about your intake or considering a supplement, it's worth raising with your doctor or a dietitian.
Building omega-3s into a fertility-friendly routine
Small, repeatable habits work best: aim for a couple of servings of oily fish a week, sprinkle flax or chia onto breakfast, and snack on a small handful of walnuts. As part of an overall healthy lifestyle, AGO's herbal-based formulas such as AGO Mom, AGO Eva and AGO Dad are designed to support reproductive and nutritional wellness — a gentle complement to a balanced, omega-rich diet, never a replacement for whole foods or medical care.
