Omega-3 for ADHD: what the evidence says

Omega-3 is a group of fatty acids found in oily fish and some plants, sold as a supplement and taken by some people for general health. It is not a treatment for ADHD. Some research has explored a possible modest role, but the evidence is mixed and it is not a recommended ADHD treatment. If you want to try it, speak to a pharmacist or clinician first, especially if you take medication. This is information, not medical advice.

Information only, not medical advice. Omega-3 does not treat or cure ADHD. Speak to a pharmacist or clinician before starting any supplement, particularly if you take medication, are pregnant, or have a health condition.

What omega-3 is

Omega-3 fatty acids, including EPA and DHA, occur in oily fish such as salmon and mackerel, and in plant sources such as algae and flaxseed. They are sold as supplements, often as fish oil or, for those avoiding fish, algae-based capsules. As a supplement, omega-3 is marketed for general health, not as a medicine for ADHD.

What the evidence does and does not say

The honest position is that omega-3 is not a treatment for ADHD. Some studies have looked at whether it has a modest role, but findings are mixed and reputable bodies do not recommend it for that purpose. Treat strong claims with caution, and remember a supplement is not a substitute for clinical care. For the wider picture of managing adult ADHD, see what actually helps.
