Dietary supplements are big business, with one recent estimate showing the industry is worth almost $64 billion in the United States alone. Take a casual scroll through your social media and you’ll find influencers hawking all kinds of supplements. But how effective are they? How are they regulated? And why are these “natural” remedies so appealing to millions of Americans?
To size up the science and culture of supplements, Host Flora Lichtman talks with supplement researcher Pieter Cohen, and Colleen Derkatch, author of Why Wellness Sells: Natural Health in a Pharmaceutical Culture.
Guests: Dr. Pieter Cohen is an Associate Professor of Medicine at Harvard Medical School and an internist at the Cambridge Health Alliance where he leads the Supplement Research Program.
Dr. Colleen Derkatch is the author of Why Wellness Sells: Natural Health in a Pharmaceutical Culture and professor of rhetoric at Toronto Metropolitan University.
