Supplements are not a substitute for a nutrient-dense diet. I say that as someone who formulates supplements. Because the research is clear, and I'd rather be honest with you than sell you something without context.
Food comes first. Always. You can't out supplement your diet.
Here's what that actually looks like in the preconception window.
Protein and more than you think
Protein is the structural foundation of every cell, hormone and enzyme your body produces. In the preconception window, adequate protein supports follicular development, hormone production and the cellular environment that an embryo will implant into.
Aim for a palm-sized serve of quality protein at every meal.
Think eggs, meat, fish, legumes, dairy.
If you're plant-based, be intentional about combining sources and consider that your requirements are slightly higher to account for digestibility.
Healthy fats — non-negotiable
Your sex hormones are made from cholesterol. Oestrogen, progesterone, testosterone, all of them require dietary fat to produce. Women who chronically undereat fat often have disrupted cycles and poor luteal phase support, even when everything else looks fine on paper.
Prioritise: avocado, extra virgin olive oil, oily fish (salmon, sardines, mackerel), nuts and seeds, eggs. These also provide the fat-soluble vitamins A, D, E and K - that are critical in the preconception window.
Iron-rich foods
Iron deficiency is one of the most common nutritional issues I see in women trying to conceive and one of the most underdiagnosed. Low iron affects energy, ovulation and the ability to sustain early pregnancy.
Red meat two to three times per week is one of the most efficient ways to maintain iron stores. If you're vegetarian, pair plant-based iron sources (legumes, leafy greens, tofu) with vitamin C at the same meal to enhance absorption. And get your iron studies checked - not just Ferritin as that only tells you what's in storage. We want the whole picture.
Folate-rich foods...not just the supplement
Leafy greens, legumes, avocado, eggs and liver are all rich in dietary folate. These matter alongside, not instead of a supplement containing activated folate. The preconception folate requirement is high enough that food alone rarely covers it, but food-based folate is more readily absorbed than synthetic folic acid and adds meaningfully to your overall status.
Antioxidant-rich foods for protecting egg quality
Oxidative stress is one of the primary drivers of poor egg quality. The antioxidant capacity of your diet directly influences the follicular environment your eggs are developing in and that development takes around 90 days.
Colour is your guide here. Berries, dark leafy greens, tomatoes, capsicum, beetroot, carrots. Aim for variety across the colour spectrum every day, not just a token handful of spinach.
Then comes the supplements.
Food is the foundation. But in the preconception window, even a genuinely good diet often has gaps.
Folate requirements are high enough that food rarely covers them. Iodine is difficult to get from diet alone in Australia. Vitamin D deficiency is widespread regardless of dietary intake. Choline, critical for fetal brain development is almost universally insufficient even in women eating well.
This is where a well-formulated prenatal earns its place. Not as a replacement for what you're eating. As the safety net underneath it.
Natal Support was formulated specifically for this window. With activated nutrients in forms the body can actually use, at doses that move the needle. It's what I took through my own preconception journey, through IVF, pregnancy and now postpartum.
Food first. Then this.
