Fragile X syndrome
Supplements studied for fragile x syndrome.
Overview
Fragile X syndrome has one reviewed supplement: Acetyl-L-Carnitine (DEX Score 44; low effect size, low evidence, medium trust). Oral acetyl-L-carnitine did not appear to improve thinking skills in children with fragile X syndrome across the available trials, with no clear cognitive gains on standard measures.
Some parents reported less hyperactive behavior, but teachers did not observe the same improvement in those studies. Evidence does not support cognitive benefit from this supplement in the available research. See the heatmap and evidence reviews below for details.
