To critics, he is a purveyor of pseudoscience, capitalizing on fear
and hope to hawk unproven—and sometimes dangerous—remedies
New York, N.Y. — Dr. Mehmet Oz, the cardiothoracic surgeon turned Emmy-winning television host, has long been a polarizing figure in the medical community. To his millions of loyal viewers, he is a trusted guide through the maze of modern health trends.
To critics, he is a purveyor of pseudoscience, capitalizing on fear and hope to hawk unproven—and sometimes dangerous—remedies. As his media empire expands, so does the debate: Is Dr. Oz a well-meaning educator or a profit-driven opportunist?

The Rise of America’s Doctor
Oz rose to fame in the 2000s as a frequent guest on The Oprah Winfrey Show, where his charisma and surgical credentials made him a relatable authority.
By 2009, he launched The Dr. Oz Show, promising to empower viewers with “the best health information on the planet.”
The show became a ratings juggernaut, blending medical advice with dramatic demonstrations—think “poop bacteria” in Petri dishes and “fat-busting” miracle pills.
But his shift from evidence-based medicine to sensationalist segments soon drew fire. In 2014, he was grilled by the U.S. Senate’s Consumer Protection Committee for promoting weight-loss supplements like green coffee bean extract, which he called a “magic weight-loss cure.” Senator Claire McCaskill (D-MO) accused him of offering “false hope” to vulnerable audiences. “You’re being made an example of because of the power you have,” she warned.
The Pseudoscience Playbook
Critics argue Oz’s tactics follow a familiar formula: amplify anecdotal success stories, tout “groundbreaking” natural remedies, and downplay rigorous science. Episodes have featured segments on psychic mediums predicting cancer, “energy healing” bracelets, and hydroxychloroquine as a COVID-19 treatment—the latter contradicting CDC guidelines at the time.

Perhaps most damaging was his endorsement of dietary supplements. A 2014 British Medical Journal study found that over half of his recommendations lacked credible scientific backing. Many products he promoted, like raspberry ketones and garcinia cambogia, were later linked to misleading marketing and FTC fines.
Dr. David Gorski, a surgical oncologist and outspoken Oz critic, argues his influence is uniquely harmful. “He’s a credentialed expert leveraging his reputation to legitimize quackery. When he says ‘miracle,’ people listen—even if the evidence isn’t there.”
Profits and Partnerships
Skeptics also highlight Oz’s financial ties to the products he promotes. While he claims not to endorse specific brands, investigations reveal indirect benefits. For example, he invested in Sharecare, a health app that partnered with supplement companies. His 2022 Senate campaign in Pennsylvania further fueled accusations of opportunism, with opponents citing his pandemic-era embrace of unproven COVID-19 therapies.
The FDA has repeatedly warned Oz over misleading claims. In 2015, the agency sent a scathing letter about his episode on the antidepressant-like effects of saffron, stating it “raises significant public health concerns.” Meanwhile, supplement makers have paid millions in FTC settlements for false advertising tied to his endorsements.
Defenders: Bridging the Gap Between Academia and Main Street
Oz’s supporters counter that he democratizes medical knowledge for everyday Americans. “He meets people where they are,” says Dr. Jane Simmons, a family physician in Ohio. “Not everyone reads The New England Journal of Medicine. He sparks conversations about health.”
Others argue his holistic approach—blending traditional and alternative medicine—resonates with patients disillusioned by rushed doctor’s appointments and high drug costs. Episodes on mindfulness, nutrition, and preventive care, they note, have inspired positive lifestyle changes for many viewers.
The Broader Implications
The debate over Dr. Oz reflects deeper tensions in public health communication. A 2020 JAMA study found that nearly 60% of Americans struggle to discern evidence-based health advice from misinformation. Oz’s critics argue his blending of fact and fiction exacerbates this confusion.
“He’s a symptom of a broken system,” says Dr. Lisa Schwartz, a Dartmouth researcher who studies medical misinformation. “When entertainment values dictate health messaging, patients lose trust in real science.”
A Legacy in Question
Oz’s pivot to politics—he ran as a Republican for Pennsylvania’s Senate seat in 2022—has further complicated his image. While he lost to John Fetterman, his campaign reignited scrutiny of his medical claims. Opponents aired ads highlighting his COVID-19 remarks and supplement scandals, framing him as a “fraudulent salesman.”
Yet, his popularity endures. With a new wellness-focused podcast and partnerships with companies like Oprah Winfrey’s OWN network, Oz remains a cultural force. His defenders argue that dismissing him outright ignores the nuances of his impact.
Conclusion: Empowerment or Exploitation?
The question of whether Dr. Oz is a “nut” hinges on perspective. To skeptics, his legacy is one of eroded trust and exploited vulnerabilities. To fans, he is a visionary unafraid to challenge rigid medical orthodoxy.
What’s undeniable is his role in shaping how millions approach health. As the line between medicine and entertainment blurs, Dr. Oz’s career serves as a cautionary tale—and a litmus test for how society navigates the murky waters of information, credibility, and commerce.
