Omega-3 fatty acids made easy: learn EPA vs DHA, how fish oil works, and when to use icosapent ethyl (Vascepa) in real clinical practice. In this lecture from This is Why, Dr. Busti connects PUFAs (polyunsaturated fatty acids) to outcomes, focusing on triglyceride lowering, cardiovascular risk reduction, and the key differences between OTC fish oil supplements and prescription EPA.
You’ll learn how to:
- What omega-3 fatty acids (EPA & DHA) are and how they work
- Fish oil (EPA vs DHA): what matters clinically (and what doesn’t)
- How omega-3s affect triglycerides and hypertriglyceridemia
- Icosapent ethyl vs “fish oil”: dosing, indications, and counseling
The goal = make medical education easy and clinically relevant.
