In recent years, studies have begun to show that omega-3 fish oils can help people suffering from depression or mood swings. This is a new area of research, so treating depression with omega-3 is not as established as, say, Prozac, but the results so far have been promising.

EPA or DHA?

The active ingredients in omega-3 fish oil are eicosapentaenoic acid (EPA) and docusahexaenoic (DHA). Studies for depression and bipolar have focused on EPA, with doses ranging from about 1g to 4g (note: this is much higher than the average omega-3 supplement you'll find in your local supermarket!)

The use of DHA is controversial. It can have benefits for physical health, but one UK expert believes that supplements containing DHA are less effective. Unfortunately, the only DHA-free supplement available in the UK is very expensive.

However, a US doctor, when summarising current research, concluded that DHA does not seem to interfere with the antidepressant and mood-stabilising actions of EPA.
