Welcome back to The Fertility Dietitian Podcast. If you're over 35 and trying to conceive, you've probably searched for the best supplements for egg quality—and found yourself overwhelmed by endless recommendations for CoQ10, NAC, melatonin, omega-3s, and expensive fertility supplement bundles. But here's what I want you to understand: you cannot out-supplement a body that isn't being properly supported. Age matters, but your fertility is influenced by so much more than the number of candles on your birthday cake.
In this episode, I'm breaking down the supplements worth discussing for egg quality and fertility after 35, including what the research actually tells us about CoQ10, omega-3 fatty acids, prenatal vitamins, melatonin, and NAC. We'll also talk about the foundations that matter just as much—sleep, nutrition, metabolic health, gut function, and nutrient status—and why your supplement protocol should be based on your individual needs rather than someone else's success story. The goal isn't to take more supplements. It's to build better biology.
