Summary

What you eat measurably moves mood — but the honest version is narrower than the headlines: improving a genuinely poor diet and adding EPA-rich omega-3 are real *adjuncts* to depression treatment (not replacements), correcting an actual nutrient deficiency (B12, folate, iron, vitamin D, zinc) reliably lifts the mood and fatigue that the deficiency was causing, and swallowing those same nutrients when you are already replete does close to nothing for your mind. ---

MODERATE that improving a poor diet and adding EPA help *as adjuncts* in clinical depression; MODERATE-HIGH that *correcting a genuine deficiency* lifts mood and energy; LOW that population-wide supplementation of replete people does anything for mood. The single biggest threat to all of it — reverse causation and confounding — is named explicitly throughout.Last updated June 2026
