One small study of minerals in red blood cells found that young Canadian children with autism had
lower levels of RBC selenium and RBC molybdenum than neurotypical children of the same age, but similar levels of most other minerals.

In contrast, a study of Turkish children with autism found that they had lower levels of zinc in
plasma and RBC compared to neurotypical children.

Research – Treatment
A large, randomized, double-blind placebo-controlled study found that a similar strong, balanced
multi-vitamin/mineral supplement resulted in modest but statistically significant improvements in
the Average Change of all symptoms on the Parent Global Impressions-Revised, and significant
improvements in subscores in expressive language, tantrumming, hyperactivity, and overall
symptoms. The supplement improved the level of many vitamins and minerals. There were also
many improvements in metabolism, including improvements in oxidative stress, methylation,
glutathione, sulfation, plasma ATP. The children with low levels of vitamin Kand biotin (both made
by gut bacteria) improved the most.

One small randomized, double-blind, placebo-controlled study published found that a strong,
balanced multi-vitamin/mineral supplement resulted in improvements in children with autism in
sleep and gut function, and possibly in other areas.
