      A parent of a young elementary-school boy with ADHD and autism gives DHA. After a lapse in dosing, spinning and head-shaking behaviors were noticed, but overall no major improvement was seen.

      Side effects in reviews

      The one review we collected mentions no side effects. That doesn't mean there are none.

        Call emergency services or go to the ER right away if your child

        • struggles to breathe or is wheezing
        • has swelling of the face, lips or tongue
        • becomes confused or has a seizure

        If an unusual change lasts more than a few days, tell your child's doctor.

        Where this comes from

        We only pick posts in which parents describe trying something with their own child, from public parent forums and personal blogs. We don't copy the posts: we pull out the result, duration and side effects, write a short summary, and link every review to its original. These are parents who chose to write, so the numbers may differ from the real picture.
