New evidence
Zinc supplementation improved motor scores in autistic children over 12 weeks — but the finding comes from a reanalysis of six studies, not a fresh trial.
This is one of the first pieces of meta-analytic evidence linking zinc to motor function in autism, but with no blinding and a single 12-week duration, it’s an early signal — not a settled recommendation.
In a reanalysis of six multinational studies, children with autism who took oral zinc showed improvements on two clinical scales: the CARS (a measure of autism severity) and the TGMD-2 (a test of motor skills). The effect was moderate and statistically significant, but because the analysis pooled existing data rather than running a new blinded trial, the results should be treated as promising but preliminary.
Where this fits in the evidence
This is among the first studies we've indexed on Zinc for Improved Motor Function — treat it as an early signal until more research accumulates.
