Can you really slow the aging process? In this episode of Next Level Health, Dr. Melinda Ring talks with functional medicine physician and researcher Dr. Kara Fitzgerald about the science of biological aging and what actually influences it. They unpack DNA methylation in simple terms, discuss why it's never too late to improve your health, explore the evidence behind biological age testing, and explain how a diet rich in polyphenols, protein, and key nutrients may support healthier gene expression. Dr. Fitzgerald also shares practical strategies for healthy aging, women's health, and building habits that promote vitality for years to come.
