Title: Effect of a Polyphenol-rich Plant Extract on Attention-Deficit Hyperactivity Disorder (ADHD): A Randomized, Double Blind, Placebo and Active Product Controlled Multicenter Trial.
Brief Summary: This double blind, randomised controlled trial examines the effect of a commercially available nutritional supplement on behaviour of ADHD patients, as well as on their physical and psychiatric co-morbidities, and level of oxidative stress and immune activity, as compared to placebo and standard pharmaceutical treatment for ADHD.

    * No sexual activity
    * Use of acceptable methods of birth control including intra-uterine device, oral, implantable,or injectable contraceptives.

Exclusion Criteria:

1. History of, or current, medical condition or laboratory result which, in the opinion of the investigator, unfavorably alters the risk-benefit of study participation, may jeopardize subject safety, or may interfere with the satisfactory completion of the study and study-related procedures.
2. Serious structural cardiac abnormalities, cardiomyopathy, serious heart rhythm abnormalities, or other cardiac problems that may place the subject at increased vulnerability to the sympathomimetic effects of a stimulant drug.
3. History of seizure disorder (except febrile seizures prior to age 5 and with last occurrence at least 1 year prior to study participation), Tourette's disorder, or intellectual disability of minor severity or greater (DSM5 criteria).
4. History of psychosis, bipolar disorder, anorexia nervosa, bulimia, or suicide attempt. Current depression, anxiety, conduct/behavior disorder, substance use disorder, or other psychiatric condition which, in the investigator's opinion, may jeopardize subject safety or may interfere with the satisfactory completion of the study and study-related procedures.
5. Active suicidal ideation as evidenced by an ideation score of 2 or greater on the C-SSRS.
6. History of severe allergic reaction or intolerance to MPH.
7. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, or creatinine greater than 1.5x the upper limit of normal. Elevated bilirubin due only to Gilbert's syndrome is not exclusionary.
8. History of alcohol abuse or illicit drug use.
9. Use of prescription medications (except per protocol allowed medications) within 7 days of Baseline (Visit 2), except for ADHD stimulant medication (72 hours) and monoamine oxidase inhibitors (MAOIs) (14 days), and over-the-counter medications (except birth control and allowed medications) within the 3 days preceding Baseline (Visit 2). Medications not covered in allowed medications or prohibited medications must be cleared by the medical monitor prior to enrolling the subject.
10. Use of psychotropic medications including antidepressants, mood stabilizers, and antipsychotics.
11. Participation in a clinical trial with an investigational drug within the 30 days preceding study enrollment.
12. Previous treatment experience with HLD200.
13. Positive screening for illicit drug use or nicotine and/or current health conditions or use of medications that might confound the results of the study or increase risk to the subject.
14. In the opinion of the investigator, the subject may have problems complying with the protocol or the procedures of the protocol, or for which the study could pose unnecessary safety risks. This includes current health conditions or use of medications that might confound the results of the study or increase risk to the subject.
15. A sibling or step-sibling that is concurrently participating in this study who resides with and is cared for by the same parent/legal guardian as the subject.
