Vitamin D and Your Health Autism

Autism Information

Due to its scope, autism is a topic which begets a certain sense of urgency. Vitamin D Council would like to act on that urgency by increasing the accessibility of information which could one day prove pivotal in bringing an end to the growing epidemic.

It is plausible that vitamin D deficiency is a major contributing factor to the onset and progression of autism. Though only still a theory, first put forth by Vitamin D Council Executive Director Dr. John Cannell, the idea of a major role for vitamin D in the etiology of autism is gaining momentum. From Harvard scientists to Swedish research teams, more and more scientists are examining the possible link between vitamin D deficiency and autism in the hopes that Cannell's theory will hold up against scientific scrutiny — what would herald the discovery of a simple, natural solution to an increasingly-common, and very tragic, condition.

Listed below are links to the information on vitamin D and autism that our site has to offer, as well as to the latest studies as published in medical journals.

Quick info: To lower risk of autism, Dr. Cannell recommends at least 5,000 IU of vitamin D3 per day for pregnant women. For autistic children, Dr. Cannell recommends at least 2,000 IU of vitamin D3 per every 25 pounds of body weight per day, with frequent monitoring of 25(OH)D, targeting 100 ng/mL (250 nmol/L).
