But don't other, non-drug remedies exist for symptoms of ADHD? The short answer is yes. Because experts still aren’t sure what’s causing the jump in ADHD cases—theories range from nutrient deficiencies to growing public awareness to increased toxin exposure—it makes good sense to explore a wide variety of strategies and remedies that may be helpful.

The toxins theory has research chops behind it: A Centers for Disease Control and Prevention study published this year in Pediatrics found children with above-average levels of organophosphates (a common pesticide) in their urine were twice as likely to be diagnosed with ADHD.
