From Saving Lives to Selling Supplements: A History of Vitamin A

About this episode:  

Vitamin A is essential for good vision, a healthy immune system, cell growth, and reproductive health, and it has proved to be a critical tool in fighting childhood mortality in parts of the world where access to nutrient-rich foods is limited. But while Vitamin A has saved many lives, supplementation isn't necessary for most people, despite what you may read online. In this episode: a slate of experts from the Johns Hopkins University join host Lindsay Smith Rogers to dive into the history of vitamin A supplementation, how it has shaped global health, and what this incredible nutrient can't do despite its benefits.
