I've set 2 things aside that came from the ND, and even though I think he's a good practitioner, I've had to figure this out myself (I would encourage you to read the Cutler book, and read back posts here)
I set aside the zeolite spray
and the Liver Detox capsules that I figured out were what was causing a persistent headache--I hadn't read the label for the ingredients- and at the dosage he had me taking, I was getting 800 mg of ALA per day. The headache went away when I quit taking it.
ALA is in alot of products today, and you'll hear alot being said about it being the antioxidant everyone needs to take--but, according to Cutler, it stirs up mercury in the brain, and needs to be used in the way he lays out in his chelating protocol. I hadn't realized that the the NAC product I had taken for my liver also had it in it.
