The Claim

Supplementation with 3.36 grams per day of EPA and DHA omega-3 fatty acids for 30 months significantly reduces gingival crevicular fluid levels of macrophage inflammatory protein-1β in the left quadrant and lowers the systemic neutrophil-to-lymphocyte ratio in adults with stable coronary artery disease on statin therapy, suggesting a direct anti-inflammatory effect on both oral and systemic compartments.

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.

Cause and effect

In plain English

Taking a specific type of fish oil supplement every day for two and a half years may help reduce inflammation in the gums and lower a blood marker of body-wide inflammation in people with stable heart disease who are already on statins.

What the research says

1 study
  1. Study: Omega-3 fatty acids and oral and systemic inflammation: A secondary analysis of a randomized trial in patients with coronary artery disease.

    Taking omega-3 supplements for two and a half years helped reduce inflammation in the gums and blood of heart disease patients, just like the claim says. It’s like the supplements acted as a natural anti-inflammatory for both the mouth and the body.
