The administration of vitamin therapies (e.g. the vitamin/mineral/amino acid/hormone/enzyme combination) has not been shown to be of benefit in a controlled clinical trial; the rationale advanced for these therapies is unproven; and the previous use of these therapies has not produced any scientifically validated, significant results. Moreover, the long-term effects of chronic administration of many of the ingredients in these preparations are unknown.

Because of the above facts, the National Down Syndrome Society does not endorse the use of vitamin-related therapies. We urge parents considering the use of vitamin therapies for their children with Down syndrome to first consult with their family physicians.

We continue to believe that good health care, quality educational programs, a stimulating home environment, and positive support from family, friends and the community are currently the best avenues for enabling people with Down syndrome to develop their full potential and lead fulfilling lives.
