A small change can make a big difference
Did you Know
ACETAMINOPHEN WAS NEVER PROVEN SAFE before being approved for infants and children
Over 50 studies DID NOT TEST TO SEE IF ACETAMINOPHEN WAS SAFE FOR A BABY'S BRAIN but claimed it was
PHARMA COMPANIES FALSELY MARKETED IT AS "SAFEST" even though it had never been tested.
The Acetaminophen and Autism Connection
Based on the scientific evidence we now know that many, if not most, cases of autism are a chemically-induced injury which occurs when babies and children with oxidative stress are given acetaminophen (commonly branded Tylenol in the U.S.).​​
How could this be?
Hearing that acetaminophen use in susceptible babies and children causes autism can be very alarming for many parents and guardians.
There is much to consider, like how do we know, how much autism is caused by it, which babies and children are susceptible, and what do we do without acetaminophen?

Acetaminophen was Never Proven Safe
In 2021, we asked the question: Is the medical literature correct? Can the literally hundreds of papers in the medical literature claiming that acetaminophen is safe be correct?
​
The answer was found to be a resounding NO.​
Acetaminophen was never proven safe for a baby’s brain.
It was proven safe for a baby’s liver, but not for their brain. Read more about how this could possibly be true.
What Do We Do Without Acetaminophen?
Scientifically speaking, acetaminophen has never been proven to provide any long-term benefits to children. It also has never been tested as safe for children.
For many, this will be very surprising.
