Episode 477: A Boatload of Data on Omega-3 Benefits
Heart Doc VIP with Dr. Joel Kahn
Outro
Joel Kahn signs off, reiterates key actions and repeats the Fresh Pressed Olive Oil Club offer.
This week, Dr. Kahn dives into four new research papers on omega-3 fatty acids and their impact on heart and brain health. The discussion highlights several eye-opening findings, including reduced atrial fibrillation risk and improved cardiovascular outcomes in patients undergoing hemodialysis. Dr. Kahn also explains how omega-3 intake supports brain health and why the "right" dose depends on the specific condition being addressed. Food sources, fish oil, algae-based supplements, and ahiflower are compared as practical ways to reach optimal omega-3 levels.
Additional topics in this episode include newly approved AI software for early detection of heart disease, the role of statins in patients with type 2 diabetes, the science—and hype—around NAD+ boosters, and emerging data on Prolon fasting for Crohn's disease. Dr. Kahn also reviews concerning research on heart rhythm risks associated with high-intensity endurance exercise in athletes over the age of 50.
As always, the episode blends cutting-edge research with real-world clinical insight to help clarify what actually matters for long-term heart health.

More About This Episode
This episode takes a deeper look at why omega-3 blood levels matter more than simply taking a supplement. Dr. Kahn reviews large population studies linking higher omega-3 levels to lower risks of atrial fibrillation, early-onset dementia, and major cardiovascular events, including in high-risk groups such as patients on hemodialysis. The key takeaway: testing omega-3 status and personalizing intake may be far more effective than a one-size-fits-all approach.
Beyond omega-3s, Dr. Kahn explores several timely and surprising topics, including AI-enhanced CT scan technology designed to detect silent heart disease without additional radiation, real-world data on statin benefits in patients with type 2 diabetes, and why costly NAD+ supplements may ultimately function as a form of vitamin B3. The episode also examines new evidence on fasting-mimicking diets for Crohn's disease and potential heart rhythm risks in high-level endurance athletes over 50.
Throughout the discussion, Dr. Kahn emphasizes practical, evidence-based steps patients can review with their physicians, including omega-3 blood testing, coronary calcium scoring, and tailoring lifestyle and supplement strategies to individual risk factors.
