When AI Doctors Go Rogue: The Shocking Truth Behind Their Dubious Health Advice
Ever stumbled upon a so-called “doctor” on Instagram who’s pushing some wild health cure—like soaking your feet in hydrogen peroxide to ‘reset your immune system’? Sounds bizarre, right? Well, buckle up, because Dr. John Valentine isn’t your typical medical professional. In fact, he’s not even a real person. This AI-generated avatar is part of a growing army of synthetic doctors spreading dubious health advice to millions across social media—amassing massive followings while blurring lines between fact and fiction. How are these digital doctors reshaping the way we consume health info, and more importantly, what does that mean for truth in the age of AI? Let’s dive into this intriguing blend of technology, trust, and truth. LEARN MORE.

Taylor Coffman first encountered Dr. John Valentine when a relative sent her one of his videos.
“It’s the classic tale of arguing with a relative about something that they’re just sort of dug in on,” she said.
The argument was about hydrogen peroxide, and Dr. Valentine was a huge fan. His one minute Instagram video, which attracted over 275,000 likes and more than 20,000 comments, advised people to soak their feet in the liquid for 10 minutes before bed.
“By morning, your entire immune system resets. After one week, chronic infections disappear,” he said.
Coffman, an actor who writes about health on Substack and creates video content while fighting a rare disease, recognized the claims as nonsense. She texted a duck emoji to her relative—shorthand for quack.
“My relative texted me, ‘Well nothing you say is checking out about hydrogen peroxide and this is a doctor and you’re not,’” Coffman said.
Except he’s not a doctor. He’s not even human. The Dr. Valentine account (@healthylifesage) uses an AI avatar in surgical scrubs to dispense often dubious health advice to more than 1.3 million followers.
As for the account’s claims about the healing powers of hydrogen peroxide, Dr Margot Burnell, president of the Canadian Medical Association, told Indicator that they’re “misleading and disturbing.”
The fake Dr. Valentine is one of more than two dozen accounts identified by Indicator that feature synthetic doctors and medical professionals across Instagram, Facebook, Threads, TikTok, and YouTube. They collectively have more than 8.5 million followers or subscribers, and often receive tens or even hundreds of thousands of engagements on their content.
