Key Takeaways

  • Get your omega-3 index tested – Aim for 8% or higher EPA/DHA in red blood cell membranes for maximum longevity benefits
  • Take 1.5-2g daily of EPA/DHA – This dose can raise omega-3 index from 4% to 8% in just 3 months
  • Eat fatty fish 3x/week – Wild salmon is ideal (high omega-3s, low mercury)
  • Prioritize EPA/DHA over ALA – Marine sources are more effective than plant sources (walnuts/flax)
  • Omega-3s offset smoking damage – Smokers with high omega-3 index have same life expectancy as non-smokers with low index

Supplements & Protocols Mentioned

  • EPA/DHA: 1.5-2g daily (safe upper limit is 4g as used in prescription formulations)
