Attention-Deficit Hyperactivity Disorder (ADHD) is generally considered to be a developmental disorder, largely neurological in nature, affecting about 5% of the world’s population. The disorder typically presents itself during childhood, and is characterized by a persistent pattern of inattention and/or hyperactivity, as well as forgetfulness, poor impulse control or impulsivity, and distractibility.

According to Dr Hoffer’s ABC of Natural Nutrition for Children, many learning and behavioural disorders including ADHD are a result of insufficient nutrition to the brain. Some other factors include toxic metal poisoning of soft tissues, an impaired ability to manage glucose, and food and environment allergies.

  • Overconsumption of sugar and refined flour
  • Gestational and early childhood nutrition
  • Vitamin and mineral supplementation
  • Exposure to food additives
  • Food sensitivities and allergies
  • Toxic exposure (especially in cities with pollution)

Orthomolecular treatment of ADHD often includes the use of the following supplements:

    “(A) study by the University of Adelaide in Australia found (that) when 130 children between the ages of 7 and 12 with ADHD were given fish oil capsules daily, behavior dramatically improved within three months. . . When the researchers compared their results to studies of Ritalin and Concerta for ADHD, they found that fish oils were more effective.” (The Daily Mail June 20, 2006; ABC News Online June 21, 2006)
