The selected supplements are all available over-the counter (OTC) and considered by the FDA to be GRAS (generally recognized as safe) and fall under safety regulations of the DSHEA Act (Dietary Supplement Health and Education Act). We have chosen to obtain the supplements from a highly reputable compounding pharmacy, Kirkman Laboratories to avoid additives and food dyes often present in OTC supplements that may cause negative side effects in some autistic children. Kirkman Laboratories has been manufacturing prescription drugs and nutritional supplements since 1949 using Standard Operating Procedures required by the FDA (FDA registration 3025062). Their manufacturing process is based on "Good Manufacturing Practices" as defined by the FDA and is monitored by an independent quality control department.
