Fish oil comes from the tissues of oily fish and is one of the richest sources of 2 essential omega-3 fatty acids, EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). Our bodies need omega-3 fatty acids; however, since our bodies cannot manufacture them, we must get them either by the food we eat, for example, sardines, tuna, salmon, mackerel, herring, bluefish, and black cod, or by taking supplements.

When there are low levels of omega-3 in the body, it may cause a variety of cognitive and mood problems some of which can be similar to ADHD symptoms.

ADHD and Omegas

Research shows that people living with ADHD have lower levels of omega-3 in their bodies compared to people who do not have ADHD. This does not mean that having low levels of omega-3 causes ADHD or that taking an omega supplement will cure ADHD. However, research shows that taking a supplement can improve your ADHD symptoms, which is great news.

Benefits of Omega-3 When You Have ADHD

There are many benefits to taking an omega-3 supplement:

- Improvement of ADHD symptoms such as improved attention, ability to focus and memory.

- May contribute to a reduction in the symptoms of coexisting ADHD conditions, such as anxiety, depression, and bipolar disorder.

- Possible reduction in side effects from stimulant medication prescribed for your ADHD. As always check with your doctor before taking supplements.

- Many women with ADHD suffer from PMS, and their ADHD symptoms are exacerbated. Taking an omega-3 supplement can reduce PMS symptoms.

- Improve your general health. When you are living with ADHD it is easy to forget other aspects of your health too. Omega-3 can help with cholesterol levels, heart health and decrease asthma symptoms.
