Myths vs facts: Omega-3 Index and blood sugar

The Omega-3 Index (percentage of EPA and DHA in red blood cells) is often marketed as a biomarker for cardiovascular health, but its link to blood sugar is more nuanced. Some studies suggest that higher omega-3 levels, especially EPA, may improve insulin sensitivity, while others report a slight increase in fasting glucose with very high doses. This is not a myth but a complex relationship: effects depend on dose, baseline status, and individual genetics. The Omega-3 Index alone is not a reliable predictor of blood sugar issues and should not replace standard measures like HbA1c or fasting glucose. MyBody-X tests are for adults and provide lifestyle orientation, not medical diagnosis. Evidence is moderate (human-moderate) from intervention studies and meta-analyses, but insufficient for clinical recommendations. Caution: self-supplementation without medical guidance can be risky, especially in individuals with diabetes or prediabetes.
