Omega 3 fatty acids have been headline news for the past few years, especially for their effects on mood, concentration and brain health. Omega 3 covers a range of fatty acids including eicosapantaoneic acid (EPA) and docosahexanoic acid (DHA), both of which found in plentiful quantities in oily fish. EPA and DHA are important in the maintenance of brain cell membranes while DHA is associated with transmission of important mood-regulating hormones such as serotonin, dopamine and norepinephrine.
Fish oil has demonstrated a ‘significant antidepressant effect’ in a wide range of clinical trials. Omega-3 makes up a substantial portion of the brain tissue and fights inflammation, considered to be a major driver of depression.
As a result, low levels of omega 3 in the body are associated with mood disturbance, cognitive issues (such as mental processing speeds and memory),depressive symptoms and low energy*. The good news is that many trials show supplementation can help reverse this, improving mood, cognitive function and elevating energy levels*. This is particularly important in the UK, as the standard British diet lacks the oily fish intakes in east Asian or Mediterranean diets.
