Agreed than anyone trying to make a buck out of swindling parents trying to help their kids is about a low as it gets.
I was pointing it out because it seems legit and some parents of autistic kids might see it.
There's also been some interesting studies looking at heat shock and autism. The original idea came anecdotally from caregivers: some kids' symptoms lessened when they got fevers. Heat shock as in fevers, saunas, heavy exercise - and possibly sulforaphane (all involve the NRF2 pathway).
Caveat: not all kids are helped - and they have NO idea why they might be different from the ones that are not.
