  • WorksStimulant medicationThe strongest short-term evidence of anything for ADHD, in children and adults.

    Methylphenidate (Ritalin, Concerta) and amphetamines (Adderall, Vyvanse) beat placebo clearly, whether you, your doctor or a neutral observer judges. In adults the effect is medium-sized.

    Large population studies also link being on medication with fewer accidents, injuries and deaths. Side effects such as lower appetite, poorer sleep and a small rise in pulse and blood pressure are common, so a doctor adjusts the dose and checks your heart readings.

    Stimulants carry an FDA warning about misuse and addiction: store them safely and never share them.

  • WorksNon-stimulant medicationWorks, less strongly than stimulants on average. An option if stimulants do not suit you.

    In children, atomoxetine (Strattera), viloxazine (Qelbree), guanfacine (Intuniv) and clonidine all beat placebo. In adults the clearest evidence is for atomoxetine; viloxazine is also approved for adults, while guanfacine and clonidine are approved in the US for children only.

    Effects are smaller on average than stimulants, and more people stop atomoxetine and guanfacine than placebo. They are not controlled drugs, so the stimulant shortage does not affect them.

    Atomoxetine and viloxazine carry an FDA warning about suicidal thoughts in children and teens, so watch for mood changes, especially early on. Guanfacine and clonidine lower blood pressure and pulse rather than raising them, and must not be stopped suddenly because blood pressure can rebound.

  • WorksCBT for adultsThe best-tested talking therapy for adult ADHD. Moderate benefit, best alongside medication.

    ADHD-focused CBT teaches concrete skills: one calendar and task system, breaking tasks down, planning the first step, and handling the thoughts that lead to putting things off. Trials show a moderate improvement in symptoms.

    The 2025 review found the benefit showed up clearly when clinicians rated it and less when patients did, so expect real but not dramatic change.

  • WorksParent trainingReliably improves behaviour, family stress and parenting. The first step for children under 6.

    Behavioural parent training teaches routines, clear instructions, praise and consistent consequences. It improves behaviour and home life in blinded studies, and the American Academy of Pediatrics recommends it first for children under 6.

    Its effect on the core ADHD symptoms themselves is more modest.

  • WorksBetter sleep (behavioural sleep help)In children with sleep problems, fixing sleep improved sleep and ADHD symptoms in a large trial.

    In a trial of 244 children, two short sessions on bedtime routines and sleep habits improved sleep, ADHD symptoms, behaviour and parents’ wellbeing. Melatonin helps children fall asleep sooner, but has not been shown to improve ADHD itself.

    Adult trials are few, but poor sleep makes attention worse for anyone, so it is worth checking first.

  • Weak evidenceIron or zincMay help only if you are actually low, and even then results are mixed. Get a blood test first.

    A few small trials suggest children who are low in iron (ferritin) or zinc may improve when the shortfall is corrected, but results are inconsistent. There is no good evidence that topping up someone with normal levels helps, and too much iron is harmful.

    Ask your doctor for a test rather than guessing.

  • MixedExerciseSmall to moderate benefits in children, less proof in adults. Cheap, safe, worth doing anyway.

    Meta-analyses in children and teens find small-to-moderate gains in symptoms and thinking skills. The best-run trials show smaller effects, and adult studies are few.

    It is good for mood and sleep, so it is a sensible add-on, not a replacement for treatment.

  • MixedMindfulness and meditationSmall benefits in trials. Low risk, but the evidence does not single it out.

    Mindfulness programmes show small benefits in trials. In adults they looked good when clinicians rated them but not when patients rated themselves.

    Many people enjoy it and it is low risk, but the evidence is not strong enough to single it out.

  • MixedtDCS (mild electric brain stimulation)Experimental. Some trials positive, others not. Not something to try at home.

    In the 2025 adult review, tDCS beat control only when clinicians rated it, not when patients did. One home-based adult trial was positive for inattention; trials in teenagers were mostly negative.

    Treat it as research, not treatment.

  • Weak evidenceADHD coachingPeople like it, but there are few good trials.

    The studies so far are few and mostly small, often with college students and without strong comparison groups. A larger structured campus programme (ACCESS) helped, but it was built on CBT rather than coaching alone.

    A good coach may well help you; there just is not the proof to say coaching in general works.

  • Weak evidenceBody doublingPopular and harmless, but almost no research yet.

    Working alongside another person (in the room or online) is one of the most talked-about ADHD tricks. As of 2026 the research is a 12-person virtual reality study, a student poster and a thesis, with mixed results.

    It is plausible, cheap and harmless, so try it if it helps you. Our free focus room is one way.

  • Weak evidenceElimination diets and removing food coloursLook good when parents rate them, mostly vanish when outsiders do.

    Strict "few foods" diets show large effects in parent ratings, but those trials are small and parents know what their child is eating. Removing artificial colours shows a small effect, and studies disagree on whether it holds up when teachers or observers rate it.

    A small group of children may react to specific foods; this needs a dietitian, not guesswork.

  • Weak evidenceMagnesium and vitamin DSmall, low-quality trials. Not enough to recommend.

    A handful of small trials suggest a possible small add-on effect, but they are not good enough to rely on. If you are low in vitamin D for other reasons, treat that.

    High-dose supplements can cause harm, so check with a doctor first.

  • Weak evidenceSaffronA few small trials from one country. Not replicated.

    Small trials in Iran reported saffron doing about as well as a low dose of methylphenidate. Nobody else has repeated those results, so it is too early to trust them.

  • Weak evidenceEndeavorRx (prescription video game)Improves a score on a computer attention test, not clearly daily life.

    The FDA-cleared game improved children’s results on an attention test, but did not clearly improve what parents saw at home in the main trial. The maker was sold in 2024 for about $34 million.

  • Doesn't workOmega-3 (fish oil)No meaningful effect on ADHD symptoms.

    The Cochrane review, the most careful kind of summary, found little evidence that omega-3 or omega-6 supplements improve ADHD symptoms in children and teens. It is widely sold for ADHD anyway.

  • Doesn't workNeurofeedbackNo benefit when the people rating the results do not know who got the real thing.

    Across 20 trials and 1,214 people, neurofeedback showed essentially no effect when the people rating it didn’t know who had the real thing. Trials using standard protocols showed a small effect, not enough to justify the cost: it is often sold as a course costing thousands of dollars.

  • Doesn't workMonarch eTNS (forehead nerve stimulator)FDA-cleared, but a larger fair trial found it no better than a fake device.

    The device was cleared in 2019 on a study of 62 children. A later trial of 150 children with a sham (fake) device found it safe but no better than the sham on symptoms, attention, mood or sleep.

  • Doesn't workCaffeineDid not clearly beat placebo in small children’s trials. No adult trials.

    Seven small children’s trials, taken together, showed no clear benefit over placebo. Plenty of adults with ADHD use coffee to get going, and that is fine, but it is not a treatment, and it can make sleep worse.

  • Doesn't workCutting out sugarSugar does not cause or worsen ADHD in controlled tests.

    In blinded studies where neither parent nor child knew who had sugar, there was no effect on behaviour. Cutting sugar is fine for general health; it will not change ADHD.

How this works, and why

How we rate

We trust studies where the people judging the results didn’t know who got the real treatment. Many ADHD remedies look great when parents or patients rate them and shrink to nothing when a neutral observer does. That gap explains most of the hype.

The short version

Medication has the strongest evidence, for children and adults. For adults, ADHD-focused CBT is the best-tested non-drug help; for young children, parent training comes first. Good sleep matters for everyone. Exercise is worth doing anyway. Fish oil, neurofeedback, cutting sugar and the FDA-cleared forehead stimulator did not hold up in fair tests.

No ADHD treatment yet has high-quality evidence beyond about a year, according to a 2025 review of every meta-analysis in the field. Most trials last weeks or months.

Common questions

What is the most effective treatment for ADHD?

Stimulant medication (methylphenidate or amphetamines) has the strongest short-term evidence in both children and adults. Non-stimulants work too, more modestly.

Does fish oil (omega-3) help ADHD?

The 2023 Cochrane review found little evidence that omega-3 supplements improve ADHD symptoms in children and teens.

Does neurofeedback work for ADHD?

A 2025 meta-analysis of 20 trials found essentially no effect when the people rating results did not know who had real neurofeedback.

What helps adult ADHD without medication?

ADHD-focused CBT has the best evidence, with a moderate benefit. Exercise, mindfulness and good sleep are reasonable add-ons with weaker or mixed evidence.
