Impacts of Fish Oil on ADHD Symptoms: An Examination of Possible Results
Fish oil supplements, rich in omega-3 fatty acids, have shown modest but positive effects in improving certain symptoms associated with Attention Deficit Hyperactivity Disorder (ADHD), according to recent research.
People with ADHD often have lower levels of omega-3 fatty acids in their blood compared to unaffected individuals, which negatively impacts brain function relevant to ADHD symptoms. Supplementation with omega-3s can support brain health by aiding brain tissue protection and communication between brain cells, leading to symptom improvements in attention, visual learning, memory, and hyperactivity.
Several studies, including a 2017 review and research published in Neuropsychopharmacology, have found that omega-3 supplements reduce hyperactivity and enhance working memory and attention in children and adults with ADHD. For instance, a study found that taking omega-3 supplements could reduce symptoms of inattention in boys, half of which had ADHD.
While fish oil supplements are generally considered safe with mild side effects, users should choose high-quality products free of contaminants and consult healthcare providers before starting supplementation, especially children and those with allergies. Despite promising evidence, fish oil is seen primarily as a complementary treatment, with clinical guidelines such as those from The American Academy of Pediatrics recommending ADHD medications and behavioral therapies as primary treatments.
It is unclear how long omega-3 might take to affect ADHD positively, but a study found an improvement in attention after 16 weeks of supplementation. If someone with ADHD wishes to see an improvement in their symptoms, they could also consider medication, as a 2023 review states that stimulant treatment is effective in treating ADHD cases. However, such medication has potential side effects, including the risk of dependency, changes in appetite, and changes in blood pressure.
In summary, omega-3 fish oil supplementation is backed by scientific evidence as a beneficial adjunct for ADHD symptom management, improving cognitive and behavioral outcomes modestly. It is not regarded as a standalone cure or replacement for established ADHD treatments. If you or someone you know experiences symptoms of ADHD such as procrastination, organizational problems, difficulty following instructions, fidgeting, impulsiveness, or being easily distracted, seek a doctor's advice.
