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](https://www.amazon.com/Dirty-Genes-Breakthrough-Program-Optimize/dp/0062698141)* and founder of [Seeking Health](https://www.seekinghealth.com/), 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.
