What's an Omega-3 Index and Why Is It Important to Your Health?
Omega-3 fatty acids are essential for sustaining human life. While many people recognize the importance of omega fatty acids in a healthy lifestyle, recent evidence reveals that low levels of fatty acids in the blood are linked to increased mortality from all causes — including heart disease and cancer.
A comprehensive analysis spanning 17 prospective studies with over 40,000 participants across 16 years demonstrated a 15–18% lower risk of all-cause mortality among those with higher blood levels of polyunsaturated fatty acids (PUFAs). Early detection of omega fatty acid deficiencies and appropriate supplementation can help reduce the risk of chronic disease and premature death.
Although the analysis did not specify how participants consumed polyunsaturated fatty acids (PUFAs), research identifies the best dietary sources as cold-water fish and other sea life. These sources provide optimal concentrations and ratios of omega-3 EPA and DHA — the key fatty acids that reduce chronic inflammation, one of the root causes of many diseases.
Omega fatty acids — particularly omega-3, 6, and 9 — play critical biological roles, including reducing inflammation, combating oxidative stress, and supporting neurological and cardiovascular health. The human brain, composed of roughly 100 billion neurons, is about 60% PUFAs by structure. Every cell in the body relies on PUFA-based membranes for performance, making these nutrients essential to maintaining systemic cellular health.
High-quality fish oil supplements provide the ideal EPA-to-DHA ratio and avoid the harmful toxins (such as mercury) sometimes found in fish. A large-scale study in the UK involving 427,000 participants found that taking fish oil supplements was associated with a lower risk of cardiovascular disease and overall mortality. Similarly, “The Heart and Soul” study showed that low levels of EPA and DHA were correlated with increased all-cause mortality and accelerated telomere shortening — a biological marker linked to faster aging and a shorter lifespan.
Everyone seeks ways to enhance longevity and improve quality of life. Research indicates that maintaining optimal omega-3 levels in the blood contributes to a longer, healthier life with less disease risk. Because omega-3s influence every cell in the body, higher levels translate to more energy, vitality, and sustained wellness — empowering you to continue doing the things you love for years to come.
