Inflammation & the cytokine route to low mood
One of 5 mechanistic pathways to 🌤️ Mood & stress resilience · 11 options
Inflammatory cytokines cause depressive symptoms directly — give someone interferon and a meaningful fraction become clinically depressed. Where mood tracks with illness, gut trouble or autoimmunity, this pathway is the one to test before the monoamine ones.
Give someone interferon and a meaningful fraction become clinically depressed — the causal link is not in doubt. If CRP is raised and mood is low, this pathway comes first.

What engages this pathway
Ordered by how directly each one acts on the mechanism above — never by how much trial evidence exists. Each links to its full breakdown with dosing, half-life and vendor.
🧬 Omega-3 (Fish Oil)
Meta-analyses show antidepressant effect, and it is specific to EPA-predominant formulations — a detail that explains most of the negative trials, which used DHA-heavy oil.
🧬 Super EPA (Fish Oil)
The high-EPA concentrate the successful trials actually used.
🧬 Curcumin
Several RCTs show antidepressant effect, plausibly through NF-κB and IDO — the enzyme that diverts tryptophan away from serotonin under inflammatory conditions.
🧬 NAC
Trial evidence in bipolar depression, OCD and trichotillomania. Glutathione restoration plus glutamate modulation.
🧬 Vitamin D
Deficiency correlates strongly with depression across cohorts. Supplementation trials are mixed and best in those who were genuinely deficient.
🧬 Probiotic
Specific strains reduce anxiety and depression scores in trials — the gut-brain axis operating through vagal signalling and cytokine reduction. Strain specificity is not optional here.
🧬 High-Potency Probiotic
Multi-strain coverage for the same argument.
🧬 Saffron
Antioxidant and anti-inflammatory activity alongside the serotonergic effect.
💉 Low Dose Naltrexone
Microglial TLR4 antagonism, where the depression looks inflammatory.
🧬 Palmitoylethanolamide (PEA)
Glial modulation with a good safety record.
🧬 SPMs (Pro-Resolving Mediators)
Direct resolution signalling where the inflammatory load is the driver.

Frequently asked questions
Inflammatory cytokines cause depressive symptoms directly — give someone interferon and a meaningful fraction become clinically depressed. Where mood tracks with illness, gut trouble or autoimmunity, this pathway is the one to test before the monoamine ones.
11 options are mapped to this pathway in the Vault, including Omega-3 (Fish Oil), Super EPA (Fish Oil), Curcumin, NAC. They are grouped by the mechanism they act through rather than ranked by how much trial evidence exists — 9 carry clinical validation and 1 are mechanistic predictions.
Give someone interferon and a meaningful fraction become clinically depressed — the causal link is not in doubt. If CRP is raised and mood is low, this pathway comes first. The markers worth checking are hs-CRP (High-Sensitivity C-Reactive Protein), TNF-Alpha, ESR (Sed Rate), ANA (Antinuclear Antibodies).
Unproven is not the same as ineffective. Of the 11 options on this pathway, 9 have clinical validation and 1 are graded theoretical — meaning the mechanism is sound but the specific human trial has not been run, which is true of a great deal of what works in this space. Nothing on this page is ordered by evidence tier, because sorting by trial count would bury the compounds you came looking for.
