I kept getting Facebook ads with a man in a lab coat claiming a “Japanese doctor discovered a plant extract that reverses type 2 diabetes in 3 weeks”. The doctor was named Dr. Takashi Kadowaki from University of Tokyo. Big claims. Big red flags. So I did what I should’ve done first: checked if Dr. Kadowaki actually said any of this.
Who Dr. Takashi Kadowaki actually is
Real guy. MD, PhD. President of Toranomon Hospital in Tokyo, professor emeritus at University of Tokyo. He’s legit famous in diabetes research. His lab co-discovered adiponectin receptors AdipoR1 and AdipoR2. Those receptors help regulate insulin sensitivity. He also developed AdipoRon, a small-molecule agonist that mimics adiponectin in mice.
So did he endorse a “diabetes cure”?
No. And that’s where the scam starts.Snopes senior reporter Jordan Liles investigated the exact ads I saw. His finding: scammers created fake marketing using Dr. Kadowaki’s name. The video ads use deepfake AI. Sometimes they show a different man entirely, possibly Kyoto University professor Shinya Yamanaka, not Kadowaki. Dr. Kadowaki never endorsed a “plant extract” diabetes reversal method. The ads lie. youtube.com.
What the scam websites actually do
I clicked through. Same playbook every time:
- Fake authority: Video starts with “CDC, Nature, JAMA, New England Journal of Medicine” logos and quotes. None of those institutions endorse the product.
- The bait: “Free recipe using kitchen ingredients” in the first 5 minutes. Gets you hooked.
- The switch: After 20 minutes of story, they push you to buy supplements.
- The trap: Past victims report hidden subscription charges of hundreds per month. “Money-back guarantees” often aren’t honored.
FTC has been warning about this for years. They sent cease-and-desist letters to companies claiming supplements can “treat, prevent, or cure diabetes” without evidence. FDA rules are clear: no dietary supplement can legally claim to diagnose, treat, cure, or prevent any disease.
What real science says about “curing” diabetes
Dr. Kadowaki’s actual research is on adiponectin and insulin resistance. AdipoRon, his drug candidate, works in obese mice. That’s lab research. Not a supplement. Not a “kitchen recipe”. There’s no cure for type 2 diabetes right now. Endocrinologists are blunt about it: “There’s no cure for diabetes at the moment, but it can be managed”. Diabetes UK and Diabetes.co.uk both warn that sites selling “100% effective cures” prey on hopeful patients.
Red flags that told me this was fake
- Deepfake video: The “Dr. Kadowaki” in the ad isn’t him. Lip sync is off if you watch close.
- Miracle timeline: “3 weeks to reverse diabetes” is not how human metabolism works. Real research takes years.
- Plant extract secrecy: They never name the actual plant or dose until you pay. Real science publishes data.
- “Throw away your insulin”: That exact phrase shows up on scam sites. Any site telling you to stop prescribed meds is dangerous.
- Fake journal citations: Slapping CDC/Nature logos on a sales page isn’t endorsement.
Bottom line
Dr. Takashi Kadowaki is a respected diabetes researcher. But he has nothing to do with these “cure” ads. The ads use AI deepfakes, fake journal names, and emotional stories to sell overpriced supplements with hidden subscriptions. If you have diabetes, talk to your actual doctor before buying anything online. And if you already paid these scammers, file a complaint with IC3 at ic3.gov with screenshots, charges, and the website link. Real research from Dr. Kadowaki’s lab on adiponectin receptors might lead to future drugs. But in 2026, there’s no supplement, plant extract, or 3-week recipe that cures diabetes. Anyone telling you otherwise is selling something.
Dr. Takashi Kadowaki Diabetes Cure FAQs
Did Dr. Kadowaki discover a diabetes cure?
No. He’s a real diabetes researcher at University of Tokyo. He never endorsed a plant extract or supplement. Scammers stole his name for ads.
Is the video real or AI?
AI deepfake. Lip sync is off and sometimes it’s not even his face. Real doctors don’t announce cures in Facebook ads.
Can a plant extract reverse diabetes in 21 days?
No. There’s no cure for type 2 diabetes in 2026. Some plants may help blood sugar, but nothing reverses it in 3 weeks or replaces insulin.
Why do the ads show CDC and Nature logos?
Fake authority. Those groups don’t endorse the product. Real studies get published in journals, not sales videos.
Is the Dr. Takashi Kadowaki diabetes supplement FDA approved?
No. The FDA doesn’t approve dietary supplements before they’re sold. No supplement can legally claim to cure, treat, or reverse diabetes. The products in those Kadowaki ads aren’t FDA approved and the FDA + FTC have warned companies for making fake diabetes cure claims.
What’s the catch if I buy it?
$69 for the first bottle, then hidden $89/month autoship charges. FTC has sued companies for this exact tactic.
I already paid. What now?
Cancel your card, file a complaint at IC3.gov, and tell your doctor what you took.
