Double Strength 360 EPA / 240 DHA NOW® Super Omega EPA has twice the EPA (360 mg per softgel) as in our regular strength product (180 mg per softgel). This fish oil concentrate is molecularly distilled and manufactured under strict quality control standards. It is tested to be free of potentially harmful levels of contaminants such as PCBs, dioxins, mercury and other heavy metals. From the FDA: "Supportive but not conclusive research shows that consumption of EPA and DHA omega-3 fatty acids may reduce the risk of coronary heart disease. Consuming EPA and DHA combined may help lower blood pressure in the general population and reduce the risk of hypertension. However, FDA has concluded that the evidence is inconsistent and inconclusive. One serving of Super Omega EPA provides 1.2 grams of EPA and DHA." Natural color variation may occur in this product.
