In the first full episode of Think Well, Do Well, Dr. Bradford pays tribute to the late Scott Adams before diving into a topic he discusses regularly with patients at NatureWorks Best: how high-dose vitamin C selectively damages cancer cells while largely sparing healthy tissue.

Cancer cells often have low levels of the enzyme catalase, which normally breaks down hydrogen peroxide into harmless water and oxygen. When vitamin C is given intravenously at high doses, much of it converts to hydrogen peroxide outside the cells. Healthy cells neutralize this easily thanks to abundant catalase; many cancer cells cannot, leading to oxidative stress and potential damage.

Dr. Bradford references University of Iowa research (highlighted in a 2017 Science Daily piece) explaining why earlier vitamin C cancer studies often failed—frequently due to improper delivery and dosing (oral vs. IV). He also covers practical oral “tolerance” dosing for everyday immune support and shares why vitamin C remains a powerful tool for both infection recovery and selective cancer-cell stress.
