What every parent planning a pregnancy should know about folic acid, folate, and the prenatal environment that shapes a child's neurodevelopment.
I'm joined today by Dr. Ben Lynch, DNM — one of the most knowledgeable experts I know on methylation pathways, biochemistry, and how prenatal nutrition shapes a child's lifelong health. Dr. Lynch is the author of Dirty Genes and founder of Seeking Health, and over the years he has become one of the physicians I turn to most for insight on these critical early developmental windows. In this episode, we go deep on a topic that doesn't get nearly enough attention in conventional obstetrics: the difference between synthetic folic acid and the natural folate forms that developing babies actually need — and what happens when we get it wrong.
In this episode, we cover:
- Why folic acid is not the same as folate — and why that distinction matters profoundly in pregnancy
- How synthetic folic acid can block natural folate from reaching the developing brain
- The connection between folic acid food fortification and rising autism rates
- Sperm health, chromosomal integrity, and the 90-day fertility preparation window
- Practical guidance on prenatal nutrition, real food, and folate-based supplement choices
- Why acetaminophen during pregnancy depletes glutathione in both mother and baby
- How vaccine adjuvants interact with the immune tolerance state of pregnancy
