What if removing and replacing part of your blood could turn back some of the measurable signs of aging? Brianna Stubbs talks with Dr. Brad Younggren — emergency physician, former Army doctor, and CEO of Circulate Health — about therapeutic plasma exchange (TPE). They cover how the procedure works, what the blinded Circulate trial found (including an average 2.6-year reduction in biological age over three months), TPE's unique potential to clear microplastics from the bloodstream, and the broader impact of our environment—the exposome—on human healthspan.
