What elements do hyperactive children usually lack? First of all, we have to figure out if it is ADHD, because children are more athletic and active and curious, and we can’t treat active and curious as ADHD, hyperactivity is a common manifestation in children. According to the clinical point of view, zinc deficiency and ADHD are related, that is, the lack of trace elements zinc, so zinc supplementation is equally important. In case of zinc deficiency, supplementation is done at 0.5-1mg/kg. There is also a little experience from clinical work that children with lead poisoning are also hyperactive, so don’t forget to check for lead and troubleshoot lead poisoning.
