    Product Description

    EPA is an ω-3 fatty acid abundantly available in marine organisms. It is oxygenated by COX-1 and COX-2 at rates of approximately 5% and 30%, respectively, compared to arachidonic acid (Item No. 90010).1 EPA has been shown to offer protection against coronary heart disease, thrombosis, ischemic brain injury, scaly dermatitis, and some inflammatory diseases.2,3
