RxOmega-3 Factors  A recent article, published in the Journal of the American Medical Association, showed that there was a clear relationship between dietary intake of fish and omega-3 fatty acids and reduced risk for coronary heart disease. RxOmega-3 Factors from Natural Factors is an example of a new generation of fish oil products, longchain fatty acids from marine lipid concentrates, that are revolutionizing nutritional medicine. RxOmega-3 contains more than twice the EPA and DHA per capsule contained in other brands - 400mg EPA and 200mg DHA. A 2:1 ratio of EPA and DHA, as in RxOmega-3 Factors, has been the primary ratio proven in scientific studies reporting clinical benefits from the use of pharmaceutical-grade fish oil products.
