When you’re trying to conceive, especially in your 40s, every nutrient matters. Omega-3 fats are among the most well-researched nutrients for reproductive health, yet many women don’t get enough. These essential fatty acids support healthy cell membranes throughout the body and are important for egg and sperm health, ovarian function, implantation, and early embryonic development.
In fact, research suggests that adequate omega-3 intake is associated with better fertility outcomes in both women and men. And during pregnancy, DHA plays an important role in your baby’s brain, nervous system, and vision development.
This is why getting the right kinds of omega-3s (and enough of them) is so important. Not all omega-3 sources are created equal, and quality matters just as much as quantity.
The Best Sources of Omega-3s
The richest sources of omega-3 fats are found in wild-caught seafood, particularly cold-water fatty fish such as salmon and sardines.
For optimal health and fertility, our omega-6 to omega-3 ratio should be between 1:1 and 4:1. Wild-caught salmon naturally falls within this range at 3:1, while farmed salmon sits at roughly 14:1, a dramatic difference that highlights why food quality plays such a critical role in fertility nutrition.
Why Omega-3s Matter for Fertility & Pregnancy
The forms of omega-3s found in fish, EPA and DHA, have been shown to:
- Support egg quality and ovarian reserve
- Support healthy ovulation
- Reduce inflammation that damages eggs and sperm
- Support sperm count, motility, and morphology
- Support balanced hormones and healthy cycles
- Reduce the risk of early preterm birth (by over 40% with 600–800 mg DHA daily)
- Support your baby’s brain and nervous system development
Plant-Based Omega-3s: What You Need to Consider
Plant foods such as flax, chia, hemp, and walnuts contain ALA, a type of omega-3 that must be converted into EPA and DHA. Because this conversion is limited, relying on ALA alone may not provide enough EPA and DHA to optimally support fertility.
Fortunately, microalgae oil provides a vegan-friendly source of preformed EPA and DHA, making it an excellent alternative to fish oil for those following a plant-based diet.
How to Meet Your Omega-3 Needs
Aim for:
✔ 2–3 servings of wild-caught cold-water fish weekly, or
✔ A high-quality fish oil or algae oil supplement daily
Omega-3 Rich Foods to Emphasize
✔ Wild-caught salmon
✔ Wild-caught herring
✔ Wild-caught sardines
✔ Anchovies
✔ Pasture-raised eggs
✔ Grass-fed meat
