Systemic Inflammation

Reviewed by the Nimbera editorial team · Last updated May 2026

Chronic low-grade systemic inflammation is a persistent, subclinical activation of the immune system associated with elevated biomarkers such as C-reactive protein (CRP), interleukin-6 (IL-6), and TNF-alpha. Unlike acute inflammation, it produces no obvious symptoms but silently contributes to the development of cardiovascular disease, type 2 diabetes, Alzheimer's disease, and certain cancers. Diet, lifestyle, and specific nutritional compounds have robust evidence for lowering these inflammatory markers.

When to see a doctor

See a doctor if you have persistently elevated CRP or ESR detected on a blood panel, unexplained fatigue lasting more than 4 weeks, joint swelling or pain in multiple joints, unexplained weight loss, or any symptoms suggesting an autoimmune condition. Chronic elevation of inflammatory markers always warrants a medical workup to exclude a diagnosable inflammatory or malignant cause.

Mediterranean Diet Pattern

lifestyle
Galvano et al. (2023) dose-response meta-analysis of 31 RCTs and prospective cohorts (n=17,153) published in Advances in Nutrition found that the highest adherence to a Mediterranean diet was associated with a significant reduction in CRP (weighted mean difference -0.41 mg/L), IL-6, and TNF-alpha compared to control diets (PMID 36774045).
$50-100/month food budget increase over a typical Western diet

Omega-3 Fish Oil (EPA + DHA)

ingestible
Calder et al. (2020) systematic review of 68 RCTs in Biomolecules found that EPA and DHA supplementation consistently and significantly reduced circulating CRP, IL-6, and TNF-alpha across diverse adult populations, with effect sizes greatest at doses of 2-4 g/day EPA+DHA (PMID 32977576).
$25-50/month for a therapeutic 2-4 g EPA+DHA dose

Curcumin (Bioavailable Extract)

ingestible
Tabrizi et al. (2019) systematic review and meta-analysis of 32 RCTs (n=1,520) published in Nutrition Journal found that curcumin supplementation produced a statistically significant reduction in plasma CRP (weighted mean difference -1.06 mg/L, 95% CI -1.47 to -0.65) and IL-6 across all included trial populations (PMID 30497843).
$20-45/month for a bioavailable formulation at therapeutic dose

Green Tea Extract (EGCG)

ingestible
Xu et al. (2020) meta-analysis of 11 RCTs (n=821 participants) published in Nutrition Journal found that green tea supplementation significantly reduced plasma CRP (mean difference -0.36 mg/L, 95% CI -0.55 to -0.18) and IL-6 versus placebo, with the largest effects at doses delivering over 400 mg/day EGCG (PMID 33323121).
