If you are trying to conceive naturally or through IUI, you can continue taking egg quality supplements until you get a positive pregnancy test.
If you are trying to conceive through IVF, most supplements discussed in the book can be stopped the day before egg retrieval, because at that point they are no longer needed to support egg development. Your doctor may advise you to stop taking DHEA earlier, because it performs its role on the early stage follicles and is not needed during stims.
After egg retrieval, the supplements that are helpful to continue taking in preparation for embryo transfer are:
- Vitamin D
- Vitamin E
- Possibly CoQ10/Ubiquinol
(See the post on preparing for embryo transfer)
After embryo transfer, you can then stop vitamin E and continue with your prenatal and vitamin D. There may be some benefit with continuing CoQ10 and NAC to help miscarriage, as discussed in the book, although there is little research on this.
When you do become pregnant, your supplement regime will focus on supporting your baby’s growth and development, as discussed in my pregnancy book, Brain Health from Birth.
