OmegaMatters

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

Conflicting Omega-3 Index World Maps (What's Correct?)

OmegaMatters: Episode 48
Hosts: Drs. Bill Harris and Kristina Harris Jackson
About this episode: In this episode, Drs. Harris and Jackson talk about a new world map Omega-3 paper, which prompted the question: “Why do different laboratories provide different values for blood Omega-3 fatty acids, which resulted in two very different world maps of Omega-3 status?” So they dug into the paper to see if they could understand better why they have two very different views on Omega-3 status in the world.
