Supplements & ADHD
Key takeaways
Studies suggest that people with ADHD may be more likely to have low levels of certain nutrients than those without ADHD, though more research is necessary.
Certain nutritional supplements, such as zinc, magnesium, iron, melatonin, and omega-3 fatty acids, may help manage ADHD symptoms.
EllaOla Kids’ Essential Multivitamin may be a good option for meeting your child’s nutritional needs, while Ritual Sleep BioSeries Melatonin may be a good option for adults managing sleep difficulties.
ADHD and Supplements: What Does the Evidence Say?
Many families ask whether supplements can help with ADHD. Research in this area is growing, but evidence varies significantly between products.
Omega-3 Fatty Acids
There is moderate evidence that omega-3 supplements (particularly EPA-dominant formulations) may offer small benefits for attention, emotional regulation and behaviour in some children and adults with ADHD. Effects are generally mild and gradual.
Iron, Zinc and Magnesium
Some individuals with ADHD have low levels of certain micronutrients, particularly iron or zinc. Supplementation may be helpful where a deficiency is identified, but routine supplementation without medical guidance is not recommended.
Melatonin
Melatonin does not treat ADHD itself but is sometimes prescribed to support sleep onset, particularly where sleep difficulties exacerbate ADHD symptoms.
What to be cautious about
Supplements are not regulated to the same standard as medication
High doses can cause side effects or interact with prescribed medication
“Natural” does not always mean safe or effective
At CADS, we recommend that supplements are considered:
alongside medical advice
with attention to diet, sleep and wellbeing
as part of a holistic support approach, not a standalone treatment
