Dietary Supplements

Dietary supplements are vitamins, minerals, herbs and other substances meant to improve diet.

They come in many forms including pills, capsules, powders and liquids. Some people believe that individuals with autism don't have enough of the right nutrients in their bodies, or that their bodies are poor at making use of the nutrients available to them. These people believe that these nutritional deficiencies may be the cause of some of the symptoms of autism, such as impaired communication and social difficulties, and that these problems can be overcome by taking one or more dietary supplements.

Please note:

  • Dietary supplements do not have to go through the testing that drugs do, although some countries (such as the USA) do regulate their use.
  • Some dietary supplements can produce significant and sometimes hazardous side effects in some people.
  • Some dietary supplements can interact with (and sometimes interfere with the action of) other supplements or prescribed drugs
