In this special Folic Acid Awareness Week episode of The MotherToBaby Podcast, host and genetic counselor Chris Stallman sits down with Dr. Elisabeth Marnik, PhD—a biomedical scientist, mom, and science communicator better known as @ScienceWhizLiz on Instagram. Together, they unpack the science behind folic acid, its critical role in early pregnancy, and why it's one of the most important (yet misunderstood) nutrients for people of childbearing age.
