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. Tune in for an inside look at the science, strategy, and ongoing effort to protect responsible innovation in the supplement industry!
