DHA supplements prevent depression
Mostly falseThe Claim
There is a common belief that taking DHA supplements can effectively prevent or alleviate depression, given DHA's role in brain health.
Origin
This myth comes from early observational studies and anecdotal reports linking omega-3s to mood improvements.
What Science Says
Current evidence from randomized controlled trials and meta-analyses suggests that the effects of DHA on depression are inconsistent. Some studies show slight mood improvements, but these are often not clinically significant. A 2019 meta-analysis found that while there may be small benefits for depressive symptoms, DHA alone is not a substitute for traditional treatments and shows variable results depending on the population studied.
Verdict
Mostly False
