Vitamin Therapy and Children with down Syndrome: A Review of Research
The claim that large doses of vitamin-mineral supplements benefit mentally retarded children has captured the attention of the general public and the medical profession. A study by Harrell, Capp,
Supplementation with antioxidants and folinic acid for children with Down’s syndrome: randomised controlled trial
TLDR
This study provides no evidence to support the use of antioxidant or folinic acid supplements in children with Down’s syndrome.
Nutritional supplementation in Down syndrome: theoretical considerations and current status
TLDR
This review was undertaken to determine whether there is a theoretical basis to expect that nutritional supplements may improve the pathology of DS, and to critically examine published trials of nutritional supplements in DS to determineWhether the existing evidence supports claims that nutritional supplement improve the outcome in DS.
Vitamin supplements and purported learning enhancement in mentally retarded children.
TLDR
The efforts of the authors to replicate the Harrell et al. research are documents and, although no significant differences were found between active treatment groups and control groups at study's end, a thorough comparison is made between the two research efforts.

Nutritional, dietary, and hormonal treatments for individuals with mental retardation and developmental disabilities
