Your growing womb pushes on your bladder, so expect more trips to the loo.

If you’re trying to conceive (TTC), you probably know that there are certain foods and nutrients that become especially important once you’re pregnant. But nutrition plays a vital role even when trying to conceive, much like laying a strong foundation before constructing a house.

Certain nutrients create that foundation by supporting egg and sperm health (yes, nutrition matters for both partners), hormone balance and creating a hospitable environment for a fertilized egg to implant. In fact, studies show that certain nutrients can help increase fertility and improve success rates for both natural conception and fertility treatments.

‍

In other words, nutrition is a key player in the TTC journey, but getting the right nutrients in the right quantities can be tricky. That’s where supplements come in. Just as you’d take a multivitamin to fill in nutritional gaps for optimal health, fertility supplements can give you that extra nutrient boost.
