Pine Bark Extract (Pycnogenol) for Adhd Support

Strong evidence 19 studies

Research suggests that pine bark extract (Pycnogenol) shows meaningful promise as a complementary approach for ADHD symptom support, with several randomized controlled trials reporting reductions in hyperactivity, inattention, and impulsivity in children, alongside improvements in oxidative stress markers and catecholamine levels. A 2024 network meta-analysis ranked Pycnogenol among the more effective antioxidant-based interventions for ADHD, and multiple systematic reviews and narrative reviews identify it as one of the better-supported herbal options in this space, often alongside Bacopa monnieri. That said, the overall body of rigorous evidence remains modest in scale — the RCTs are relatively small and short in duration, and several earlier reviews characterized the evidence as mixed or preliminary, calling for larger and longer trials before firm conclusions can be drawn. Studies indicate the research direction is generally positive, but the evidence base is not yet strong enough to position Pycnogenol as a clinically established ADHD treatment, and it is most accurately described as a supplement with encouraging but still-developing support.
