B12 Injections Improves Behavioral Measures in Autism

Published: September 12, 2012

Researchers from the Department of Psychiatry and Behavioral Sciences at the University of California-Davis studied 30 children with autism, dividing them into groups. One group received injectable methyl B12 every three days; the other group didn't. (The dose was 64.5 microgram per kilogram of body weight. A kilogram is 2.2 pounds.) 30% of those receiving the vitamin had "clinically significant improvement" in behavioral measures.

"Methyl B12 may alleviate symptoms of autism…possibly by reducing oxidative stress," concluded the researchers in the Journal of Alternative and Complementary Medicine.
