Studies and Research
As per a study published in Progress in Neuro-Psychopharmacology and Biological Psychiatry, taking zinc supplements can alleviate the symptoms of ADHD or attention deficit–hyperactivity disorder in children.
Researchers from Iran executed a controlled clinical trial to evaluate the benefits of prescribing zinc supplements alongside the more conventional methylphenidate treatment.
The study involved 44 children who were diagnosed as suffering from ADHD; and none of these patients had taken any medication before the trail.
For the six weeks, half the children were given zinc sulphate (55mg/day) in addition to the conventional treatment; while the other half were given a placebo. A child psychiatrist examined the children's improvements.
The researchers found that children taking supplementary zinc sulphate on a daily basis showed significant improvements than those taking a placebo.
Other Clinical Support for the use of Zinc in ADHD Therapy
Serum Zinc Levels and Hyperactivity
A 2005 study published in Journal of Child and Adolescent Psychopharmacology by 9 researchers from the Ohio State University examined the relationship between serum levels of zinc and severity of ADHD symptoms.
48 children between the ages of 5 and 10 partook in the study. The zinc serum levels for these kids were determined and then the parents and teachers ratings of their ADHD symptoms were obtained. These parent and teacher ratings ranked the children for signs of hyperactivity and inattention.
The study results showed a strong correlation between serum zinc levels and the perceived extent of ADHD symptoms.
