From the Guidelines

There is no scientific evidence supporting the use of sand as a dietary supplement for ADHD. For ADHD management, the most well-supported dietary supplements are:

  • Omega-3 fatty acids (500-1000mg daily, with at least 500mg of EPA) which potentially help with attention and hyperactivity by supporting brain cell membrane function and neurotransmitter regulation 1.
  • Zinc (5-10mg daily) and iron supplements (under physician guidance, only if deficient) may help some individuals, as these minerals are involved in dopamine production.
  • Magnesium (200-300mg daily) might reduce hyperactivity in some children. These supplements should be considered complementary approaches alongside evidence-based treatments like behavioral therapy and prescribed medications. Always consult a healthcare provider before starting any supplement regimen, as they can interact with medications and have side effects. Quality matters with supplements, so choose reputable brands tested by third parties. Remember that supplements work best when combined with a balanced diet, regular exercise, adequate sleep, and established ADHD treatment protocols.

Some key points to consider when managing ADHD:

  • Stimulant medications are highly effective for most children in reducing core symptoms of ADHD 1.
  • Non-stimulant medications, such as atomoxetine, extended-release guanfacine, and extended-release clonidine, have also demonstrated efficacy in reducing core symptoms, although their effect sizes are slightly weaker than those of stimulants 1.
  • Medication adherence is a common problem in ADHD treatment, and regular assessment and open discussion of potential issues can help increase adherence 1.
  • A balanced diet, regular exercise, and adequate sleep are essential components of ADHD management, and can help supplements work more effectively.

It's essential to prioritize evidence-based treatments and consult with a healthcare provider before starting any supplement regimen. The use of nonmedication treatments, such as mindfulness, cognitive training, diet modification, EEG biofeedback, and supportive counseling, is not supported by strong evidence and should not be recommended as a treatment for ADHD without further study 1.

From the Research

Dietary Supplements for ADHD

  • Omega-3 fatty acids have been shown to have a positive effect on ADHD symptoms 2
  • The optimal concentrations of omega-3 fatty acids for ADHD treatment are still unknown and require further research 2
  • Omega-3 fatty acid supplements may be more effective in patients with mild forms of ADHD 2

Doses of Dietary Supplements for ADHD

  • The effective dose of omega-3 fatty acids for ADHD treatment varies across studies, and more research is needed to determine the optimal dose 2
  • Combining omega-3 fatty acid supplements with stimulant medication may allow for a reduction in the dosage of stimulant medication 2

Pharmacological Treatments for ADHD

  • Stimulant medications, such as methylphenidate and amphetamines, are effective in treating ADHD symptoms 3, 4
  • Non-stimulant medications, such as atomoxetine and guanfacine, are also effective in treating ADHD symptoms 3
  • The choice of medication for ADHD is still largely based on a trial-and-error process, but guidelines and data can aid in clinical decision-making 5

Treatment Strategies for ADHD

  • A comprehensive treatment plan for ADHD may include a combination of pharmacological and non-pharmacological interventions 6
  • Individualized treatment plans should take into account the patient's unique characteristics and needs 6, 5
  • Stimulant optimization and consideration of non-stimulant medications and combined pharmacological approaches may be necessary for patients who do not respond to initial treatment 5
