Taking omega-3 supplements might help lower inflammation in older people, especially if they also exercise, which could help them keep their muscles stronger as they age.
See the scientific wording
Omega-3 supplementation reduces inflammatory biomarkers such as IL-6 and CRP in older adults, particularly when combined with exercise, suggesting an anti-inflammatory mechanism that may support muscle preservation.
Correlational — new studies may shift this
One low-scoring study links this claim to the outcome, but causation is not established.

The Role of Omega-3 Polyunsaturated Fatty Acids on Sarcopenia and Aging Muscle
Narrative ReviewReview2026
Taking omega-3 supplements, especially with exercise, helps older adults reduce body inflammation and keep their muscles stronger. The study shows this combo works better than either one alone.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Systematic Review of Omega-3 Supplementation and Exercise on IL-6 and CRP in Older Adults
Population: Adults aged 65+; Intervention: Daily omega-3 supplementation (e.g., 2g EPA/DHA) combined with structured resistance exercise; Comparator: Placebo plus no exercise or placebo plus exercise alone; Outcomes: Serum IL-6, CRP, and muscle mass/function measures (e.g., grip strength, lean mass via DEXA); Duration: Minimum 12 weeks with follow-up at 24 weeks.
Double-Blind RCT of Omega-3 Supplementation with vs. without Exercise on Inflammatory Markers in Older Adults
Population: Healthy older adults (65–80 years); Intervention: 12 weeks of daily 2g omega-3 + supervised resistance training; Comparator: Placebo capsules + supervised resistance training; Outcomes: Change in serum IL-6, CRP, and muscle protein synthesis markers; Duration: 12 weeks with pre- and post-intervention measurements.
Prospective Cohort Study of Omega-3 Intake, Exercise, and Inflammatory Biomarkers in Older Adults Over 5 Years
Population: Community-dwelling adults aged 60+; Intervention: Self-reported omega-3 intake and physical activity tracked over time; Comparator: Low vs. high omega-3 consumers with varying exercise levels; Outcomes: Annual measurements of IL-6, CRP, and muscle mass via bioimpedance; Duration: 5 years.
In Vitro Effects of Omega-3 Metabolites on IL-6 and CRP Expression in Human Muscle Cells Under Simulated Exercise Conditions
Population: Human myoblast cell lines; Intervention: Exposure to EPA/DHA metabolites; Comparator: Vehicle control; Outcomes: mRNA and protein levels of IL-6 and CRP; Duration: 24–72 hours with and without simulated mechanical stretch.
