Mark Hyman wants you to believe he’s biologically 39 years old. The 66-year-old functional medicine guru and twelve-time New York Times bestselling author has built an empire on the promise that the right combination of supplements, lifestyle changes, and cutting-edge treatments can literally reverse aging. “We can reprogram our genes back to a younger you,” he states in one way or another in countless podcasts. “[At] 63 I could use certain transcription factors and turn my biological clock back to 25. Make my wrinkles go away, my hair turns black, my joints get healthier.”
But earlier this year, Hyman revealed something that threatens to undermine his entire brand: he almost died.
Not from old age. Not from some unavoidable disease. From sepsis—a severe infection that spread through his spine after what he vaguely described as “a pretty common injection” for back pain.
And he’s not alone. Jordan Peterson, the pop psychologist who promotes anti-wokeness as a key to mental well-being, was also hospitalized for sepsis as well. Peterson remains largely out of the public eye, and it’s unclear whether he’ll ever fully return.
Here’s where it gets interesting: both men share the same doctor—Adeel Khan, a regenerative medicine physician who runs a string of stem cell clinics out of Mexico, Dubai, and Japan. Khan’s patient roster reads like a who’s who of celebrity wellness: the Kardashians, Tony Robbins, and yes, both Hyman and Peterson.
Over the past two months, I’ve been investigating a story that these three highly public medical professionals have taken great pains to keep under wraps. It’s a story about how two of the most prominent wellness influencers in the world promoted Khan’s dubious stem cell therapies, then nearly died while under his care. And even after their close calls, they’ve remained largely silent—because admitting what happened would undermine the very grift pipelines that fund their lifestyles.
However, since their legal team has already been in touch, I would like to offer you a necessary disclaimer.
Important disclaimer: Everything I present here is my opinion based on investigative work using publicly available information, interviews, and independent analysis. I haven’t directly inspected private medical records, so my conclusions are circumstantial. References to “scams,” “fraud,” or “lies” should not be taken as definitive findings of fact or legal conclusions. No statement should be interpreted as a categorical declaration that any person has violated civil or criminal law unless a court has so ruled. I encourage you to examine the evidence and reach your own conclusions.
With that said, let me tell you what I found.

The Mystery Injection
When Hyman appeared on Jay Shetty’s “On Purpose” podcast to explain his six-month absence from public life, he told a carefully curated story. He explained that he’d suffered from chronic back problems since age 32, when he “ruptured a disc” while “chopping wood” in Idaho. (The “chopping wood” detail is fascinating—it’s become a testosterone-boosting lifehack in wellness circles, and the story positions Hyman as some sort of uber-masculine figure in touch with his primal nature. In reality, according to his biography, he was a small-town doctor at the time, not a lumberjack.)
This old injury had caused “chronic disc degeneration,” Hyman explained, and he’d been seeking treatment. “I ended up having an injection, which is a pretty common treatment to help relieve pain,” he told Shetty. “And one of the risks of injections of any needle is infection.”
Notice how vague that is. What injection? From whom? Where?
According to Hyman, the infection “took off” in the closed space of his spine. Within days, he couldn’t walk. Within a week, he had surgery. But the surgeons “couldn’t reach the abscess” and essentially gave up. “They said, ‘We can’t do anything,’ and basically left me to die. They gave me antibiotics and said, ‘Cross your fingers, and here are some painkillers.’”
Does that sound plausible to you? Can you imagine any doctor shrugging their shoulders and leaving Mark Hyman—a man with massive social media reach and the ability to ruin a medical practice with a single post—to die?
The story gets stranger. Hyman claims a doctor friend had to tell him to seek a second opinion. Think about that: Mark Hyman, whose entire career is based on providing second opinions to mainstream medicine, needed someone else to suggest he get one?
Eventually, he made it to UCSF, “the top neurosurgery center in the world,” where a “Hail Mary surgery” saved his life. He was “maybe a couple of days away from dying.” He lost 25 pounds. He couldn’t brush his own teeth or “wipe my own ass.”
But here’s what he didn’t say: what was that injection, and who gave it to him?
The evasiveness in Hyman’s story made me suspicious. If he’d simply gotten a standard cortisone injection that happened to cause a rare infection, why not just say so? Why the vagueness?
A source in my network—someone I’m not going to name—told me they’d heard Hyman got the injection from a clinic in Mexico, and that the clinic had gone into emergency mode to control the story before it leaked.
That tip led me to Dr. Adeel Khan.
In July 2024, Khan posted a reel on social media featuring Mark Hyman. In it, Hyman explained: “The main reason I’m seeing Dr. Khan is to deal with chronic disc degeneration and disc herniation.”
Khan then described the treatment in a jump cut: “Mark Hyman has severe spinal canal stenosis, severe facet arthritis. This means the spine is very degenerated and the only way to avoid surgery, we had to use a combination of our engineered mesenchymal stem cells and also mesenchymal exosomes... So we injected them epidurally using catheters. We also injected them into the facet joints.”
Bingo. An injection into precisely the spot where Hyman’s infection began.
But there was a problem with the timeline. Hyman’s podcast with Shetty aired in August 2025, and he said the incident happened “seven months” before recording. That would place the infection somewhere between October 2024 and February 2025. Khan’s reel was from July 2024—too early.
Unless Hyman had gone back for a follow-up treatment.
That’s when I discovered something remarkable: In November 2024—right in the middle of my target timeframe—Hyman had recorded a podcast with Khan titled “The Secret to Reversing Chronic Pain & Aging Before It’s Too Late.”
And that podcast had been scrubbed from the internet.
Out of more than 1,000 episodes of Hyman’s podcast available on YouTube and Apple Podcasts, this was one of the only ones completely removed. Even the episode page and transcript had been wiped from his website. The only traces remained on the Wayback Machine and in abandoned AI summaries.
After I posted about the missing interview, one of my readers helped me obtain the audio file.
In it, Hyman tells Khan: “Last time I saw you was in Cabo when you were about to inject me with a bunch of interesting compounds that are biological compounds they use in regenerative medicine for my disc issues.”
He goes on: “I’d had steroid injections, I’d had radio frequency ablation, which I didn’t know at the time would cause secondary consequences of damage to my back through damaging the muscles in my back. So basically, I really struggled. And the only thing that’s helped me take away my back pain are these compounds that are from this toolkit of regenerative medicine.”
They even discussed opening a mutually-branded clinic together in Abu Dhabi.
Here’s my working hypothesis: Hyman had been seeking stem cell treatments from Khan’s clinic in Cabo for his ongoing back pain. According to clinical literature, these treatments require multiple injections over time. After the first shot worked, Hyman decided to have Khan on his podcast to promote this “miracle” treatment. They recorded the interview in November 2024. Right after recording, Hyman likely received his follow-up injection.
And something went horribly wrong.
The needle introduced an infection. Hyman’s dreams of recovery transformed into a near-death experience. And that’s why he deleted every reference to Khan he could find—including the podcast they’d just recorded together.
Now, you might argue that Hyman has a right to keep his medical history private. That’s the whole point of HIPAA—to prevent doctors from releasing patient information that could be used against them.
But I believe that ethic doesn’t apply to medical influencers who use their personal health histories to sell millions of dollars worth of supplements, treatments, and services.
As a public-facing doctor appearing on podcasts that reach millions, Hyman has a duty to tell the whole truth about his medical experiences, not just a highly curated spin. The Hippocratic oath states that doctors should “do no harm”—and omitting this key information harms any patient who follows his recommendations.
Hyman built his career on the promise that functional medicine and regenerative treatments are superior to mainstream medical interventions. He’s made millions selling supplements and promoting alternative therapies. His entire brand is built on the idea that he knows better than conventional doctors.
Yet when one of the treatments he promoted nearly killed him, he didn’t warn his audience. He didn’t tell them which clinic or which procedure went wrong. He just... disappeared for six months, then came back with a vague story about a “common injection” and unnamed doctors who “left him to die.”
Meanwhile, the allopathic medicine he’s spent his career positioning himself against—the emergency surgery at UCSF—is what actually saved his life.
Hyman’s case isn’t isolated. Jordan Peterson, who has also been treated by Khan, suffered his own bout with sepsis and has largely vanished from public life. Khan’s clinic has treated numerous celebrities, all while operating in jurisdictions with less regulatory oversight than the United States.
Khan himself has posted about the risks of stem cell injections on LinkedIn, noting that “the shot is not the most dangerous part of his procedures—especially in a well-run lab.”
Which raises the question: Is this a well-run lab?
The regenerative medicine field is full of promise. Stem cell therapies may one day revolutionize how we treat degenerative diseases. But it’s also rife with grift—clinics operating in regulatory gray zones, making extraordinary claims, charging enormous fees, and leaving patients to deal with the consequences when things go wrong.
What makes this case particularly egregious is the silence. These are not private citizens seeking experimental treatments in desperation. These are public health influencers with massive platforms, promoting specific doctors and treatments to millions of followers. When those treatments nearly kill them, they have a moral obligation to speak up.
Instead, they scrub the evidence and move on, hoping no one connects the dots.
The wellness industry has exploded into a multi-trillion-dollar global phenomenon. It promises everything from reversed aging to cured chronic disease to optimized performance. And it’s built largely on the personal testimonials of influencers like Hyman and Peterson.
But what happens when those testimonials are incomplete? When the success stories are highlighted and the near-fatal complications are hidden?
We’re left with a fundamentally dishonest picture of what these treatments can and cannot do. We’re left with desperate people spending thousands or tens of thousands of dollars on treatments that may not work—or worse, may harm them.
The irony is almost too perfect: Two men who built careers on questioning mainstream medicine, on promoting alternative approaches, on promising their followers they could transcend the normal limits of human health... nearly died. And the medicine that saved them wasn’t functional medicine or stem cells or supplements. It was emergency surgery performed by conventional doctors at a top-tier hospital.
I’m not saying all alternative medicine is worthless. I’m not saying regenerative medicine has no future. I’m saying that when the people selling you these treatments won’t tell you the whole truth about their own experiences—including the catastrophic failures—you should be very, very skeptical.
I’ve pieced this story together through social media posts, deleted content, interviews with experts, and conversations with confidential sources. But I haven’t seen Hyman’s private medical records, which means my conclusions remain circumstantial.
The only way to know for certain is to hear it directly from Hyman, Khan, or someone with verifiable direct knowledge of what happened. I’ve reached out to both Hyman and Khan for comment. So far, neither has responded, though Khan’s legal team has been in touch with increasingly threatening letters.
This is just the beginning of this investigation. In future installments, I’ll be diving deeper into Dr. Adeel Khan’s network of clinics, his other celebrity patients, and what happened to Jordan Peterson. I’ll also be examining the broader world of regenerative medicine—the legitimate science, the regulatory gaps, and the grifters exploiting desperate patients.
If you have information about Khan’s clinics, or about similar stem cell operations in Mexico or elsewhere, I want to hear from you. You can reach me at scott@foxtopus.ink.
Why This Matters
Three years ago, I left mainstream media—a career that included bylines in the biggest magazines in America and six published books—to become a full-time crowdfunded investigative journalist. It was terrifying. But in the last few months, I’ve finally found my footing. This community has grown to over 200,000 people who believe, as I do, that independent investigative journalism matters.
In a world where traditional media is collapsing, where health misinformation spreads faster than facts, where influencers can promote dangerous treatments without accountability—this kind of work is more important than ever.
The wellness industry doesn’t want you to hear stories like this. They want you to see the before-and-after photos, the glowing testimonials, the promises of eternal youth. They don’t want you to know about the infections, the hospitalizations, the near-death experiences.
But you deserve the whole truth. And I’m committed to finding it.
If you found this investigation valuable, please consider subscribing (it’s free) and sharing it with others. The more people who know these stories, the harder it becomes for the wellness industry to hide them.
And if you want to support this work financially, paid subscriptions make investigations like this possible. I don’t have corporate backing or advertising revenue. I have you—readers who believe that accountability matters, that truth matters, that someone needs to ask the hard questions that wellness influencers desperately hope no one will ask.
Thank you for being here. Thank you for reading. And stay tuned—because this story is far from over.
