Blueprint for Safety: The Handbook That Defined Supplement Science

How do we know how much of a vitamin or mineral is safe to take? In this episode of Supplement Source, we explore the history and impact of the Vitamin and Mineral Safety Handbook, the go-to playbook that has shaped supplement regulations and formulations for decades. Jeff Ventura sits down with Andrea Wong (CRN) and Andrew Shao (Chromadex) to discuss how this handbook became a scientific cornerstone, the fight against overly conservative regulations, and why updating it is more crucial than ever.
