First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether taking zinc supplements can help Botox injections last longer for people with cervical dystonia, a condition that causes painful neck muscle spasms. About 25 adults will take either zinc or a placebo daily for 3 months, then switch to the other for another 3 months. Researchers will measure how long symptom relief lasts and check for any side effects.
