Does omega-3 supplementation added to exercise attenuate inflammaging? Effects on circulating interleukin-6 in older adults: A meta-analysis of randomized controlled trials

Systematic Review With Meta-Analysis

Human

Taking omega-3 supplements along with exercise helped older adults lower a key inflammation marker in their blood more than exercise alone. This suggests omega-3s do help reduce inflammation, even if they’re not the only thing helping.

Modulation of Inflammatory Indices by Omega‐3 Fatty Acids Supplementation in Hemodialysis: A Clinical Trial Approach

Randomized Controlled Trial

Human

2026 May

This study gave people with kidney disease omega-3 pills for two months and found that their inflammation levels didn’t go down — they even went up a bit. So, it doesn’t support the idea that omega-3s reduce inflammation like some people think.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Taking 2000 mg of omega-3 fish oil daily for three months doesn't lower a common marker of body inflammation called hsCRP, no matter what your genes say. So, if omega-3s help your cholesterol, it's probably not because they're calming down inflammation.
