Naturopathic and Integrative Claims for ADHD and Autism: What Is Known and Cautions

What research shows about diets, supplements and other approaches for ADHD and autism, which treatments have no evidence or may be dangerous, and why your child's clinician comes first.

Back to Naturopathy & Integrative Practices

Families, and adults with ADHD or autism, are often offered a long list of natural or alternative treatments. This page sets out what the research shows, specific approach by specific approach. It is information only. For a medical emergency in the US, call 911. If a child may have swallowed a supplement, chemical or medicine, call Poison Help at 1-800-222-1222. See also poison help by country.

Start with your child's clinician

NCCIH advises talking to your child's health care provider to assess what, if any, complementary approach would help, because children may respond differently. [1] It notes that few complementary approaches have been studied for children, and that taking too much of a supplement or substituting supplements for prescription medicines can be harmful and even life-threatening. [1] Do not stop an ADHD or other prescribed medicine on your own.

Standard ADHD treatments include medication and psychosocial interventions such as cognitive behavioral therapy, parent training and school interventions. [2] For autism, NCCIH lists behavioral interventions, social skills training and speech and occupational therapy, and says early interventions and supports can greatly enhance a child's development. [1] Autism spans a range of abilities and strengths that can change over a lifetime. [1]

ADHD: what is known

8 items reportedMost serious first. The colour shows how severe each report was.
  1. St. John's wort

    Moderate

    Current evidence suggests it is no better than placebo, and it can weaken the effects of many medicines. [3] [6]

    No good evidence of benefit; interaction risk

  2. Omega-3 fatty acids

    Unclear

    NCCIH says current evidence is inconclusive on whether they help ADHD symptoms. [3] A 2013 meta-analysis found small but significant reductions even with probably blinded assessments. [4] A 2017 review of meta-analyses said the small average effects mean they are unlikely to make a tangible contribution. [5]

    Mixed

  3. Artificial food color exclusion and restricted elimination diets

    Unclear

    The 2013 meta-analysis found larger effects for color exclusion but often in children selected for food sensitivities, and said better blinded evidence is needed for restricted elimination diets. [4] The 2017 review said more research on color elimination is required before advising it. [5]

    Mixed

  4. Acupuncture

    Unclear

    Insufficient evidence to draw conclusions in children and adolescents. [3]

    Insufficient evidence

  5. Exercise, including yoga

    Unclear

    Short-term aerobic exercise, including yoga, has shown small-to-moderate beneficial effects on core symptoms. [3]

    Promising but limited

  6. Neurofeedback

    Unclear

    Evidence is mixed. [3]

    Mixed

  7. Homeopathy

    Unclear

    No evidence that homeopathic products help. [6]

    No good evidence of benefit

  8. Melatonin (for sleep)

    Unclear

    Limited evidence from rigorous trials in young people with ADHD. [3]

    Insufficient evidence

NCCIH's overall conclusion is that none of these has been conclusively shown to be more effective than conventional therapies. [3] See meditation for ADHD, yoga for ADHD and ADHD in adults.

Naturopathic and integrative care as a whole

Proper evidence not found for whole-system naturopathic care as a treatment for ADHD or autism. A PubMed search for naturopathic care with ADHD or autism returned two records, neither a trial of naturopathic treatment. Practitioners differ in training. NCCIH describes licensed naturopathic physicians as completing graduate-level education at an accredited naturopathic medical school, traditional naturopaths as training through varied non-accredited programs, and scope of practice as varying by state. [9] Pediatricians, psychologists and therapists also have their own training and rules. See credentials and scope of practice and naturopathic and integrative care for children. For vaccine questions, use health authorities: vaccines and naturopathic care. We do not list or rank practitioners.

Red flags

Be cautious of any offer that promises to "cure" autism, requires stopping medicines or therapy, sells a product to remove "toxins," or asks for an IV, injection or detox program. Ask the questions in how to evaluate a therapy claim.

Frequently asked questions

Can natural treatments cure ADHD or autism?

NCCIH says none of the ADHD approaches has been conclusively shown to be more effective than conventional therapies, and for autism it lists several treatments with no scientific evidence of benefit. [3] [1]

Is chelation safe for autism?

NCCIH says there is no scientific evidence that chelation helps people with autism and that inappropriate use may be harmful. [1]

Does fish oil help ADHD?

Evidence is inconclusive per NCCIH, and a meta-analysis found small effects. [3] [4]

Do special diets help autism?

Results are mixed, and children on special diets need monitoring by a clinician. [1]

What should I do before trying a supplement?

Talk with your child's health care provider first, since few complementary approaches have been studied in children. [1]

More details: evidence, limits and cautions

Autism: what is known and where the warnings are
NCCIH says there is no scientific evidence that secretin, hyperbaric oxygen, chelation therapies or antifungal agents can help people with autism. [1] These are not FDA-approved for autism, and inappropriate or off-label use may be harmful. [1] Chelation is a medical treatment for confirmed metal poisoning, not an autism treatment: see chelation therapy: legitimate medical uses versus alternative claims and risks of IV therapy and chelation.
ApproachWhat the sources foundEvidence label
Melatonin for sleepLow doses may help with sleep problems; providers should discuss side effects and the lack of long-term safety data. [1]Promising but limited
Omega-3, acupuncture, massage, oxytocinNCCIH says studies exist, but it is not clear whether they improve health, and they should not replace conventional treatments. [1]Insufficient evidence
Gluten-free and casein-free dietsA meta-analysis of 8 studies (297 participants) found that 5 studies reported significant reductions in stereotypical behaviors, though most studies were single-blind. [7] A separate meta-analysis of 7 randomized trials (338 participants) concluded that diet therapies can significantly ameliorate core symptoms, but found no statistically significant change in the gluten-free and casein-free subgroup, and the authors noted small trials and the need for better ones. [8] NCCIH says the research has had mixed results. [1]Mixed

Diets deserve special care in children. NCCIH says anyone wishing to try a special diet should consult a physician and have their overall nutritional needs evaluated before and during the diet. [1] NCCIH notes some people on the autism spectrum may have food selectivity that requires intervention to increase nutrition intake, and that people with autism need to be closely monitored on a special diet to avoid harmful side effects. [1]
