In this episode, I welcome back Dr. Jim Stephenson Jr., a dedicated citizen researcher who has spent years investigating the complexities of vitamin D3 supplementation. After a personal journey spurred by his wife's health challenges, Jim discovered that the common advice to supplement with D3, K2, and magnesium didn’t yield the results they hoped for. Today, we’ll explore his groundbreaking insights into how D3 functions in the body, its various metabolites, and the real implications of sun exposure. Join us as we tackle lingering questions and examine the role of vitamin D3 in health and disease, along with the surprising risks of supplementation.
