Primal Defense

Hello,
I am thinking of starting Primal Defense and perfect food soon. I am just waiting for more money to come in first. Does that mean I should stop taking my digestive enzymes,HCL, multivitamin, and bowel cleansing supplements? What else should I be taking with it? Also my 3 year old son has autism and I don't know if it's candida related that I passed to him. Would it be ok to give to him? How much? Thank you. There is such great support here!
