Vitamins can be added to the special diet of your autistic child to boost his brain function. You may have already started him on a casein and gluten free diet. Adding certain vitamins known to help stimulate mental faculties can help reduce autistic symptoms. You would probably be aware that in general, a deficiency in specific vitamins can bring about a body or brain malfunction.

Scientific studies show that out of all types of vitamins, B6 is probably the most useful. Since 1965, there have been 18 major studies on the uses of vitamin B6 to fight autism. In 8 of those studies, children with abnormalities in their urine, after taking B6 and magnesium, had normal urine.

Also, B6 and other B vitamins, have been shown to help autistic children with better mental focus and more social awareness. It may sound a little unbelievable but it is reported that some children, after taking vitamins and supplements, even spoke for the first time. Hence, if you have a child who is experiencing some speech delay, then this news can be pretty hopeful. However, if you want to give your autistic child vitamin B6, be sure to also include magnesium

supplements. This is because vitamin B6 causes a magnesium deficiency in the body.

Vitamin C is another vitamin for your consideration to give to your autistic child. In fact, studies show that a lack of Vitamin C can result in confusion and disorientation, for just about anyone. Although there have been relatively few studies on how vitamin C has an effect on autistic symptoms, the few that there have been have been successful. Most of the children tested showed similar result conclusions to the B6. After a period of consuming Vitamin C supplements, these children started showing fewer autistic signs.

There are also a number of other herbs, vitamins and supplements that you can include. These include folic acid, St. John's wort and Ginko Biloba. While no single item has a major positive effect on its own, studies do show that several vitamins taken together can produce great results.

Ask the paedrician of your child about adding vitamins to his diet. Find out which particular combination would be best for your child. In addition, you may want to make a note to monitor your child's progress just to ensure that he did benefit from these vitamins after taking them. It is also important that you let the teachers in school or any child care involved know about the special diet that your child is on. Ask for help so that everyone can chip in to see if there is any improvement in your autistic child.
