Attention deficit hyperactivity disorder in children and adolescents (ADHD)

The most frequently reported prevalence rate on ADHD is 5 to 7%. The causes of this disorder are still difficult to identify, but are certainly genetic and neurobiological. It usually manifests as hyperactivity (permanent agitation), attention problems and impulsivity (characterized by acting without thinking).

During randomized, double-blind tests, vs a placebo, Professor Suh-Ching Yang, of the Tapei Faculty of Medicine, demonstrated the effectiveness of an Oligopin® supplement (25 mg/day), DRT’s PUREXTRACT® range of pine bark extract, high in OPC.

"The CPT-II test, resulted in a significant improvement in lack of attention (18.5%) and a decrease in impulsivity (18%).”
