Hormonal

Anti-inflammatory interventions (including omega-3 fatty acids, exercise, and cytokine antagonists) significantly improve mood and reduce depressive symptoms, but only in individuals with pre-existing heightened inflammation (e.g., high CRP or IL-6 levels).

If you have depression, ask your doctor about testing inflammatory markers like CRP or IL-6. If these are high, treatments like omega-3 supplements (specifically EPA), exercise, or anti-inflammatory medications might be more effective for you than standard antidepressants alone. If your inflammation is low, these treatments may not help, and you should focus on other therapeutic strategies.

GoodQualifiesHIGH confidence
a theme across research with cytokine antagonists, omega-3 fatty acids, celecoxib, and exercise is that anti-inflammatory interventions have a substantially greater impact on mood in individuals with heightened inflammation.

Why this rating

Supported by multiple meta-analyses, prospective cohort studies, and randomized controlled trials (e.g., infliximab, omega-3s, exercise) showing dose-response relationships between inflammation levels and treatment response.
