RX Omega-3 Factors 5 5 3 3
great omegas this product has a perfect balance of omegas and no aftertaste. The gel caps are easy to take. I like them better than any other similar product. December 26, 2013
Natural Factors RXOmega-3 Factors Our entire family including the dog take these. Good quality for the price. October 15, 2013
One of the Best This fish oil has the highest concentration of omega 3's per capsule of any other fish oils that I have ever used. For example, this fish oil contains 400 mg EPA and 200 mg of DHA fatty acids per capsule whereas other high end brands will contain about 300 mg EPA 200 mg DHA or less. Drugstore brands of fish oil doesn't even come close to this stuff. Also, it is pharmaceutical grade so quality and purity is top notch. This is the best fish oil that I have been able to find and have been very satisfied in using it. December 5, 2010
