Watch episodeA RECURRING SERIES
From familiar supplements to emerging therapies, George puts the promise alongside the evidence. What is plausible? What has been shown in humans? And what are the trade-offs?
THE QUESTIONS BEHIND THE GRADE
Start with the mechanism.
Look for meaningful human outcomes.
Consider safety, access and uncertainty.
Grades are editorial assessments of evidence and context, not personal treatment recommendations. Stronger evidence can change the score.


MEET YOUR HOST
Dr. George Murphy brings the perspective of a working researcher to the conversation about living longer and healthier.
He is a Professor of Medicine at Boston University and a co-founder of the Center for Regenerative Medicine at Boston University and Boston Medical Center.
His research explores stem-cell biology, regenerative medicine, exceptional longevity, and resilience to age-related disease. On The ReProgram, he brings that curiosity to conversations with scientists—and to the claims we encounter every day.
George earned his doctorate in Molecular and Cellular Biology at the University of Oxford and completed postdoctoral training at Harvard Medical School and Boston Children’s Hospital. His laboratory uses human cellular models to investigate how some people resist age-related disease.
THE REPROGRAM PERSPECTIVE
