MYF 04 | Gene Mutations & Fertility: MTHFR, PEMT, VDR | Carrier Screening

Mastering Your Fertility by Tiny Feet Dr. Haylee and Kristin.png

In this episode we discuss how certain single nucleotide polymorphisms (SNPs) in our DNA can affect how well we can utilize specific nutrients, such as choline, folate and vitamin D, in our body. The top three SNPs discussed are MTHFR, PEMT, and VDR due to their significant impact on fertility and long term health of baby. 

In this episode you will learn how much of each nutrient you need to overcome the disadvantage of having one of these SNPs. You will hear our personal experience of being homozygous MTHFR and how we were able to maximize their health. 

Towards the end of the episode, Dr. Haylee talks about expanded carrier screening and the advantages of you and your partner being screened before pregnancy.
