Synopsis

Source of validity: Scientific
Rating (out of 5): 2

DHA (docosahexaenoic acid), an omega-3 fatty acid found abundantly in fish oil, has been investigated for its potential role in supporting or treating depression. The rationale for its use is primarily scientific rather than traditional. Epidemiological studies have observed that populations with high fish consumption tend to have lower rates of depression, suggesting a possible link between omega-3 intake and mood regulation. Biologically, DHA is a key component of neuronal membranes and is involved in modulating neurotransmission and inflammation, both of which are implicated in depression. However, clinical evidence is mixed. Some randomized controlled trials (RCTs) and meta-analyses suggest that supplementation with omega-3 fatty acids—particularly EPA (eicosapentaenoic acid), often alongside DHA—may provide a modest benefit for individuals with major depressive disorder, especially as an adjunct to conventional treatments. The effect appears to be more pronounced with higher EPA content, and results specific to DHA alone are less consistent. Major guidelines do not recommend DHA as a standalone treatment for depression, but some practitioners may suggest it as a complementary approach due to its favorable safety profile. Overall, while there is a scientific basis and some supportive clinical data, the strength of evidence for DHA's efficacy in treating depression is moderate at best, justifying a rating of 2 out of 5.
