The Claim
High-dose omega-3 fatty acid supplementation (3.6 g/day of EPA and DHA) for six months significantly reduces plasma C-reactive protein levels by approximately 23% in heavy smokers or former smokers with baseline CRP >2 mg/L, and this reduction persists for at least six months after discontinuation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking 3.6 grams of EPA and DHA daily for six months lowers blood levels of C-reactive protein by about 23% in heavy or former smokers with elevated inflammation, and this reduction remains for six months after stopping the supplement.
See the scientific wording
High-dose omega-3 fatty acid supplementation (3.6 g/day of EPA and DHA) for six months significantly reduces plasma C-reactive protein levels by approximately 23% in heavy smokers or former smokers with baseline CRP >2 mg/L, indicating a clinically meaningful reduction in systemic inflammation that persists for at least six months after discontinuation.
Omega-3 fats replace other fats in cell membranes, which stops the production of inflammatory chemicals that signal the liver to make CRP, causing CRP levels in the blood to drop and stay low even after stopping the omega-3s.
What the research says
1 studyThis study found that taking 3.6 grams of omega-3 fish oil daily for six months lowered a key inflammation marker (CRP) by 23% in heavy smokers, and the lower inflammation stayed down for six months after they stopped taking it — exactly what the claim says.
