Anti-vaccine advocate Jenny McCarthy has sparked backlash on social media after sharing a video discussing the unproven “correlation” between Tylenol’s active ingredient, acetaminophen, and autism, RadarOnline.com can reveal.
McCarthy’s post divided social media users, with some applauding the “mama bear,” whose son was diagnosed with autism as a baby, for doing her own “research.” Others called out McCarthy and accused her of spreading false and “dangerous” information without a medical degree. McCarthy took offense and clapped back in the comment section.
Jenny McCarthy Promotes Tylenol and Autism Link Theory
McCarthy’s Instagram post focused on acetaminophen’s impact on the body’s detoxification system. She captioned the video with a disclaimer: “So many calls and questions. Hope this helps a little. Note: I’m repeating what the doctors have said. Talk to your own for more info.”
The former Playboy model went on to claim acetaminophen hinders glutathione, a natural antioxidant supporting metabolic detoxification, and decreases the body’s ability to detox harmful toxins like “aluminum found in vaccines.”
Critics Slam Jenny McCarthy for ‘Spreading Misinformation’
She further claimed that while she didn’t take Tylenol during her pregnancy, she naturally has low levels of glutathione and receives weekly IV treatments to help.
Although the former talk show co-host has been open about her anti-vaccine views before, Instagram users were outraged that she was promoting the Tylenol theory. This theory has been dismissed by a significant number of healthcare providers, especially following HHS Secretary Robert F. Kennedy Jr.’s announcement regarding acetaminophen.
One user commented: “No. This is not fully true. This is again DANGEROUS information, you do not have a medical degree or have the expertise – please stop.” McCarthy replied, “This info came from the doctors. Go talk to one.”
Others wrote:
- “Please stop talking like you understand science. Still spreading misinformation. Go back to Singled Out.”
- “Unfollow I’ll listen to real doctors.”
- “Celebrity personalities are now health experts in America.”
One Instagram user warned: “You should be taking advice from board registered certified medical professionals. Nobody else.” Many pointed out the key scientific principle: “Correlation does not equal causation.”
During the heated debate, one critic took a swipe at McCarthy’s stance on “toxics” while undergoing cosmetic procedures, writing: “I don’t understand how these people talk about environmental toxins, natural this and that, gluten – blah blah, yet their entire face and body is filled with toxins, implants, fillers … MAKE IT MAKE SENSE.”
Jenny McCarthy’s Controversial Vaccine History
McCarthy has stirred controversy with her stance on vaccines for over a decade, though she has claimed to be “pro-vaccine” at one point. She wrote an op-ed for the Chicago Sun-Times in 2014, reportedly stating:
“I am not ‘anti-vaccine.’ This is not a change in my stance, nor is it a new position that I have recently adopted. For years, I have repeatedly stated that I am, in fact, ‘pro-vaccine’ and for years I have been wrongly branded as ‘anti-vaccine.’”
