Acetyl L-Carnitine has shown promise in spinal cord injuries and non-verbal autistics. My grandson, who is 7 yrs. old and severely autistic, was recently placed on Acetyl L-Carnitine 500 mg. daily. Within two weeks, he began to verbalize. Though he doesn't have speech like a normal developing child, Acetyl L-Carnitine has definitely helped launch him into verbalization.
