In this “Ask Us Anything,” we break down the omega-3 & atrial fibrillation (AFib) story (who’s at risk—and who isn’t), explain why the Omega-3 Index target is 8–12%, and cover practical decisions like how to read fish-oil labels (EPA + DHA), choosing sources (fish oil, algal oil, krill, salmon roe, ahiflower), and storing products to limit oxidation.

Omega Matters 2026 is back with Dr. Bill Harris (OmegaQuant) and new co-host Kelly Patterson, RD—answering your most-asked questions about omega-3s, the Omega-3 Index, and what the clinical data actually show.

Topics covered:

  • AFib risk: why the signal shows up mainly with high-dose omega-3 in high cardiovascular-risk patients, not typical supplement/food intakes

  • Plaque progression: what the evidence says about slowing coronary plaque growth

  • Brain health: omega-3 status and dementia risk (including early-onset dementia and APOE4)

  • EPA vs DHA (and why “both” usually wins) + common ratio myths

  • Bleeding concerns, SPMs, immunity markers (NLR), dry eye, omega-6 (linoleic acid), and omega-3 for pets
