Fatty Acids
Omega-3 (EPA + DHA)
The fatty acids your brain and heart depend on.
Omega-3 fatty acids EPA and DHA reduce chronic inflammation, lower triglycerides, and support brain structure throughout life. Large cohort studies consistently link higher omega-3 blood levels with reduced cardiovascular mortality and slower cognitive decline. The Framingham Heart Study found that participants in the top quartile of DHA levels had a 47% lower risk of developing dementia.
Dosage
RDA: 250-500mg combined EPA and DHA daily (AHA recommendation)
Optimal for longevity: Longevity researchers suggest 1,000-2,000mg combined EPA and DHA daily, targeting an Omega-3 Index of 8-12%.
Deficiency signs
~68% of Americans have an Omega-3 Index below 4%, considered high risk
- Dry, flaky skin
- Difficulty concentrating or brain fog
- Joint stiffness and pain
- Mood changes or low mood
