Vitamin therapy has been tried.
It does not work. Do not waste your money.The scientific evidence is there.

If you look closely at the claims, most stop well short of "treating autism," and we have no such treatment at present. Some children may have decreased agitation with certain vitamins, but most do not.
Dr. Jon Ahrendsen
With all due respect to my colleagues, for some children it can make positive changes. vitamin D, B6, and methyl B-12 are some ones that I have seen personally benefit SOME children. Add L-methyl Folate to the list also.

there are no vitamins that have been shown based on double blind controlled studies to have a positive effect on autism.
Lots of research going on currently.

with all due respect, there are 3 double blind placebo controlled studies that show a beneficial effect of Vit B6/Magnesium to help language, austic behaviors. there are an additional 16 non-double blind studies in the literature. Those who say there is no evidence, are not looking hard enough, or discount the published studies as "not big enough"

Vitamin therapy in autism is a very misunderstood topic because random use of vitamins is ineffective for any condition.
However, a thorough evaluation leading to a targeted treatment strategy can be very helpful for anxiety, sensory overload, mood instability, behavior disorder and more. Helping with these symptoms helps a person with autism better access needed behavioral therapies.

Random use of vitamins yes, but targeted approaches have evidence of benefit. There is proof. Do a google search for autism.asu.edu. Jim Adams PhD at Arizona state has a nice summary of published studies that do show an effect.
