Answer: B(DHEA has not been shown to alleviate ADHD symptoms)
There is emerging evidence that the herbals Bacopa (A), Pycnogenol (C), and zinc (D) supplementation may lessen symptoms of ADHD.
Bacopa monnieri is an Ayurvedic medicinal herbal widely used as a tonic and memory enhancer. In a small 12-week double-blind RCT, 36 children with ADHD randomized to receive Bacopa, 50 mg BID, showed significant improvement over placebo in tests of sentence repetition, logical memory, and pair-associative learning.1
A standardized extract of the bark from the French maritime pine (Pinus pinaster) may also help reduce symptoms of ADHD. A total of 61 children and adolescents randomized to a standardized extract of French maritime pine bark (Pycnogenol™), 1 mg/kg/d, for 1 month, experienced significant improvements in hyperactivity, inattention, and visual-motor coordination compared with placebo recipients; symptoms returned to pre-treatment baseline levels after a 1-month washout.2
There is also promising evidence that zinc supplementation may mitigate ADHD symptoms. In a large 12-week double-blind placebo controlled trial (N = 400), children and adolescents randomized to a high dose of zinc, 150 mg/d, experienced significant improvement in hyperactivity and impulsivity but not inattention over placebo.3 In an augmentation study, the addition of zinc to methylphenidate resulted in greater improvement than methylphenidate alone.4
