The Best Supplements For Your Preconception Period

The Best Supplements For Your Preconception Period

If you are thinking about starting a family it’s important that you begin to nourish your body at least 3 months prior to beginning to try and conceive. Supporting your body with the right nutrients will help to support a healthy hormone balance, regulate you thyroid, nourish your egg cells and ensure that your general health and wellbeing are optimal to support a pregnancy.

Diet plays a huge role in laying the foundation for a good healthy preconception period. As a rule of thumb, it’s a good idea to start acting like your pregnant- this means reducing your coffee, alcohol and refined sugar intake, while boosting your intake of fruits, vegetables, healthy fats, whole grains and good quality lean proteins. Making lifestyle choices as well will help to reduce your exposure to toxic chemicals and endocrine disrupting chemicals that can impact your fertility. 


However, you unfortunately can’t get all the nutrients you need in the quantities required from your food. This is where good quality, therapeutic supplements come in to play. Here are the best nutrients you may want to consider supplementing during your preconception period.

PRE-NATAL VITAMIN: Provides you with the nutrients to support healthy hormone balance & build up your nutrient stores to support a healthy pregnancy.

Look for one that has: readily available form of folate (activated), choline, iron, B-vitamins, vitamin C, beta-carotene, iodine, magnesium. We stock the Naturobest Prenatal & the Bioceuticals Innatal.

OMEGA-3 FISH OIL: Supports egg quality, reduces risk of miscarriage, reduces inflammation, balances hormones & reduces risk of gestational diabetes.

Look for one that has at least 450mg of DHA & 100mg of EPA per capsule. We stock the Bioceuticals Ultraclean DHA Omega.

IODINE: Supports thyroid health, supports development of baby’s brain and nervous system early in pregnancy 

The current RDI is 220mg during pregnancy. Make sure your prenatal includes iodine, otherwise it’s important to take another supplement between 100-300mcg per tablet. We stock the Herbs of Gold Iodine Max. If you have any thyroid conditions, make sure to check in with your clinical nutritionist or naturopath prior to supplementing. 

CO-Q10: Improves egg quality, supports sperm health & improves IVF outcomes.

 You can ask your GP to get your zinc tested and you want your zinc to be sitting at around 14. Depending on your zinc status you can supplement with between 10-40mg daily.

VITAMIN D: improves fertility and IVF outcomes, supports progesterone (the hormone responsible to support a healthy pregnancy), improves hormone& follicular health

You want to get tested an ensure your vitamin D level is between 80-100 nmol/L. Ideally, you should be supplementing with at least 1000IU daily.

MAGNESIUM: reduces cortisol, supports hormone regulation & thyroid health, reduces risk of pre-eclampsia and gestational diabetes

 You can safely supplement between 150mg-300mg of magnesium daily. Having magnesium at night can also improve sleep.
