Along with a heart healthy diet and regular cardio exercise, I would recommend eating fatty fish like cod or salmon at least twice a week. In lieu of this, any quality pharmaceutical grade fish oil supplements will supply the heart-healthy omega 3 fatty acids to your diet. It’s important to take a quality fish oil to avoid contaminants like mercury and other PCBs. You need to be careful in eating fresh fish, too – choose fish caught in the Alaskan shores or upper north in latitude where the waters are still unpolluted. I, myself, prefer fish oil supplements and take one called Triple Strength Omega 3. High in purity and omega 3 potency. But there are others out there.
